DO NOT GO HERE. They lie or at best tell you half truths. They said they could transfer my Smart Watch over to their system, "No problem, do it all the time." But AFTER, yes After they switch me over to T-Mobile they said they couldn't do it. I now have a Dumb Watch thanks to them. They said that my home location had 4G LTE with great speeds ! Even after my friend went to my house with his T-mobile phone and showed 1.3 Download speeds, they said that he didn't have what my phones would have and showed me their coverage map which show top speeds. They even showed me the little "Check Marks" on their map which was supposed to show verified users confirmations of my locations High Speeds. I now have .57 Download speeds at my location, sometimes I get 1.4 ! This AFTER I was transferred over to T-Mobile. Almost everywhere I go the speeds are slow. I called T-Mobile's Customer service to complain. After an hour and a half on the phone with her she told be she would pay the monthly payments for a new watch to correct the situation. She also said she would text me with a confirmation. No text !!! I called back the next day to inquire, they said she didn't write any of our conversation down. So they knew nothing about the agreement, and therefor couldn't do anything about it. They "will investigate". I bought the International Hot-spot package for $25 per month anticipating these High Speeds. But after the .57 speed I decided to go back in and have it removed. They told me as long as I remove it before 30 days, it would be no charges. But when I did they said it could not be taken off this bill they would have to reimburse my account later. (After complaining they took it of then,) I also complained of receiving the FULL Monthly bill coming one week after I made the move over to T- Mobile, not a prorated bill. They said it would be compensated later. Now get this... I asked if all this could be written down. They said we can't do that. I asked why, they said legal reasons. I asked if they could send my confirmation, they said No. I asked if I could take a picture of the screen that they were supposedly writing this all down, they laughed, and said absolutely not. When i tried to take a picture of the guy making all these promises he told me I wasn't allowed to to do that. Soooo, if you want nothing but promises, no verification, a run around, days back and forth to your carriers store, frequent calls to Customer Service, then T-Mobile is for you. Have a good time. read more

Thank you Jonathan and Jeff for the exceptional customer service. My husband and I both decided it was time to leave ATT wireless and give T-Mobile a try. Jonathan and Jeff were both very knowledgeable on your products, services and prices. They thoroughly explained your plans to us and helped us make the best decision for our family. You ported over 4 lines for us and the entire process was quick and easy. We left very happy customers. Again, thank you for going above and beyond our expectations and earning our trust. Your employees rock!! I'm gonna send you my best friend who wants to switch all 5 of her lines. I'm sending over my father and sister as well. Also, thank you T-Mobile for honoring our military with fantastic pricing. read more

I am writing this review to say how much I liked the Customer Service from Alec, From the minute I walked in, He was Soo helpful and attentive, It had been awhile since I had purchased a phone, He was patient and even paired it with the blue tooth in my car, It is nice to have such great Customer Service in these trying times, I would highly recommend Alec to help you with your phone and accessories! read more

Do not sign up with TMobile phone service. This review is for tmobile.com. The workers lie and are idiots. I tried to sign up with them on June 6 and the worker lied and made it sound so easy. The sim card they sent never worked; they said they would send another one- it never arrived, I cancelled service a week later, 6/23,22, and they still robbed me of a payment on June 30. The workers (not in the U.S.) never once said I needed to cancel autopay separately. Logic dictates that when an account is cancelled, the auto pay should be cancelled, too. So far, their workers have lied a total of 7 times. Do not sign up with Tmobile. The customer service is horrible and they lie and rob people, read more

I went to try and upgrade my phone and remove a line from my plan and the customer service was not good at all. The man helping me was very lazy and was no help to me at all. I spent my time on my phone on customer service most of my visit. They offered my no incentives and they were no help in explaining the plans that customer service had offered me. Go to another store if you want to deal with motivated helpful customer service. This place is not where you'll find that. read more

I was extremely impressed on the service we received from Alec Rodriguez. He went over and above providing new service to my family. I highly recommend seeing him in the Upland Store. read more

I got super nervous reading the reviews for this place. Reviews were relentless, and some of them were extremely situational. Some of them were due to an unfortunate employee that may or may not work there. But I figure most people who leave Yelp reviews are overbearing with their opinions. So let me be one of them. I have been searching for the z3 for a long time. I also needed a new phone desperately. I work hard and I felt it was time to treat myself. So I called ahead of time, and Franco answered. He let me know there was one left and he would put it aside for me. I came in, and that he did. He was EXTREMELY helpful, very nice and personable, and on top of that, he wouldn't give up after exhausting all the possible solutions for me. I was about to walk about because I couldn't afford to buy the phone that day, but he expressed he was here to help and gave me several options until they fit what I needed. He had mentioned he came from another store, and if the store is really as bad as Yelp reviews say, he must have had some sort of impact on them. I had a great experience. So if you're hesitant as to whether you should go to the T-Mobile by your house, just ask for Franco and I'm sure you'll be fine. I'm happy with my phone now, and in 2 weeks we worked a great deal for me to get the z3. Tailored to what I can do and how I want it. read more

Who said there wasn't great customer service anymore? Well this T-Mobile store was there for me when I needed it. I am a T-Mobile customer and I needed help clearing space on my phone for a vacation. My internal phone space was full and I couldn't load apps or take pics or videos without a storage full message. Eric, the store manager helped me and now I can take all the pics and videos I want. He was great. I would definitely recommend this location for you phone and service. Their staff is extremely knowledgeable and helpful. I recommend becoming a T-Mobile customer. read more

I took in my phone to get my SIM card switched out. The service here is excellent and everyone is very helpful. Both guys that helped me were efficient and my phone works great now. I will definitely come back here again! read more

I haven't went to this store in a while but they have good customer service! But I also would like to thank the company for being caring.. I've lost most of my work hrs and couldn't pay my bill.. they were very kind to help me. There were no question asked.. they said no problem!! I appreciate it!! We all go through things sometimes we need extra help!! The people in this store is real cool!! I like t-mobile. read more

Came in to get an AppleWatch and Kyle was very knowledgeable. He explained, in detail, the model availability, features of the watch, synchronized the watch to our phone, went over the billing, and we left very happy. thanks again Kyle read more

All the guys at T-Mobile on 19th and campus in Upland California are fantastic they help you with anything with a smile n with a big heart n with caring love n with kindness and thoughtfulness.....Just ask for Christian or Jeff or Andy or Kyle the all are Super and will help you please go see them and tell them Diane Z. sent you n you won't be disappointed they'll help you any way they can they go out of their way they are all extraordinary and T-Mobile is excellent I've had no problem. And they always have promotions and Hallelujah no contracts I love T-Mobile so go in and talk to any of the guys and they will help you any way possible they're awesome..... read more

This was my first time walking into this location. It was a Friday afternoon around 2:00. As soon as I walked in I was nicely greated by Christian with a warm welcome. He was professional, help me decide what phone upgrade option I had. I will highly recommend him and his team. On top of that the store was clean and shelf well stocked. I love this store! read more

Adrian has been so helpful. I've been to this store at least 6 times. I now live about 20 miles away but still go to this location and I make sure Adrian is there and able to assist me. read more

Don't believe anything T-mobile is selling you all there promotions are just a pyramid scheme and once they have you in auto pay , they'll change the term from watch you have a contact and agree a-pond , and they'll tell you you've getting a credit for your phone and then they'll apply that credit too your bill and tell you that why your bill went up , because you use that credit to pay your bill , they give you no control over that , so be very careful , and as far as them making it right they have no Intention of making it right , they've all got you !!!! Beware any new customer !!!!!! read more

We switched from Verizon to T Mobile about a year ago as the monthly price was better and the coverage map looked very much the same. The reality is that we have 1 bar of signal strength N of the 210 freeway so reception is often weak or calls are dropped. When traveling to Lake Havasu, AZ calls cannot be made in the center of town but can be made from the N or S side of the city. T Mobile coverage map is very optimistic. read more

This is, and always has been, the slowest location in the Inland Empire. It takes you 30 minutes to get help from a representative, and that's with only 1 person ahead of you. Their communication skills also lack. read more

I went to this T-Mobile station feed up and irritated with my previous provider. Immediately Grant Bunker stepped up to help my mom and I out. He was quick and knowledgeable with all the products. Ultimately helped us get an amazing deal on two of the LG7 SlimQs. Grant did a great job making us feel comfortable feeling like we were getting the best deal possible. He made the prosses quick and painless. I recommend you go here and ask for Grant, you won't be disappointed. read more

Latroye McFarland-Wilson was our mobile expert and sales associate at T-Mobile. He is truly amazing! We just switched our longtime AT&T account over to T-Mobile and could not be happier. Only regret is that we didn't do it sooner. If you go to this store do yourself a favor and ask for Latroye to help you. Latroye not only has expert knowledge he is the most polite and kind person, he continuously smiles and answers every question you may have without having to ask someone else. He has the answer instantly he goes above and beyond with his customer service he has the patience of a saint. I like going in just to say hi and be cheer'd up with his smile. This T-mobile store is always accommodating we bought several accessories including the screen protectors which have a life time guarantee and they gladly replace them for you in the store. And especially Latroye makes you feel like it's never a bother. T-mobile is very lucky to have Latroye as their employee, seriously!! read more

Most people here are pretty nice. When the place is crowded it can take FOREVER. There is one guy that works here with the worst attitude, dosnt talk, smile, look at you, don't like dealing with this particular person. read more

I just have to say...Jonathan was amazing at helping me so promptly and perfectly with my damaged phone. He is extremely knowledgeable and eager to help. Thank you so much! read more

..The employees in this store do not seem to value professionalism. I asked the employee if he was the only one working that evening as he had a family of five with him and four other customers waiting. He said 'Yes' then he said 'just joking'. Then he became passive agressive and asked me 'Are you the customer service police'. I came in again today the same employee was speaking at the top volume to the other employees while i was being helped. I mentioned to the employee helping me how inappropriate the other individuals behavior was and he had no reaction. The individual's unprofessionalism is a turn off. People pay good money for their phone plans and they deserve respectful customer care. We do not go to your store to serve your needs. Customers should matter. Also in the middle of my appointment other employees were interrupting me and the tmobile employee to say goodbye. The manager also said he set up my sim card but when i got home it wasnt working. read more

I have to share that since the time of my last review, this store stepped it's customer service all the way up. I went in for a warranty exchange an was greeted by the same blond I talked about in my original post. She said hello and told me someone would be with me soon. About 3 minutes passed and I was greeted by Franco, who provided excellent customer service. Franco was very helpful in explaining the transaction, he took the time to put a new cover on my new phone, he explaned how I should utilize dropbox to free up the memory on my phone, and he assisted me in purchasing a wireless charger. I am very happy to see that the team was focused on providing a positive customer experience. I do appreciate the good customer service. read more

I love this location very calm, chill and welcoming!! I called and Christian answered the phone let me tell you he has the best customer service ever he helped me get a new phone and was very alert and patient read more

Seriously the worst customer service ever!!!! Dominic blew smoke up our ass to make a sale and promised the phone Tuesday in store and it "didn't come in" and he didn't even call to say it didn't come in and we drove out here for nothing. Then he guaranteed us over night delivery and we'd have it Wednesday and still nothing. We call and now we have to wait a week....what a joke! Not a great start to someone that was planning on switching from Verizon! Think we will stay there now. Not worth the horrible customer service! read more

Why the bad reviews?! Maybe you didn't get Kyle? At any rate, my finacee and I were both looking to switch from Verizon since we were about to lose our unlimited data with them when we upgraded our phones (we were rocking iPhone 4S still LOL). I called around 12 on Friday (today is Monday) and Kyle answered the phone and answered a few quick questions I had about T-Mobile, data plans, and he said he had 2 iPhone 64 gigs that just arrived and he would put them on hold for me...he said he got off at 5PM and I told him I wouldn't be there until 6:30PM, he said he'd wait for me to show up...sure enough he did. He greeted us with a warm smile, talked us through the plans, had our 64 gig iPhone 6s ready to go and switched us over from Verizon with no problems at all. He was very friendly, patient, and must have spent about a good 90 minutes - 2 hours with us explaining everything and being very thorough. He showed us what was different about the new iPhone vs. my old 4S, transferred my pictures, my contacts and recommended some good cases for us. We would totally come back here just for the experience we had with him. Again, can't understand why so many bad reviews...you must not have been helped by Kyle - THANKS KYLE! read more

This store was awesome. I went in to have them activate my new iPhone 7's and switch all of my info from my old ones as well. I was helped by a gentleman named Eli. He was great. For the first time I felt someone in a T-Mobile store actually liked what they did for a living. He was very helpful and made sure I was in and out as quick as possible with no problems. Everyone else was also really nice. The store had a really nice vibe. I'd give it a 5 star but a five star to me is like Bigfoot... very rare sightings. lol read more

This place is always packed with people waiting to be helped and employees who seem not-at-all knowledgeable. While I waited there for a half hour today (before being told they couldn't help me), I heard people trying to pay their bills being told they'd have to wait 40 minutes, all the while employees were milling around. When I mentioned to the guy that they needed a better system for helping people just trying to pay their bills or get quick questions answered, he said he'd "relay the message." Get it together, T-Mobile. read more

I have been a customer of this location for 4yrs now & let me say I've Never been so Disgusted by their employees.. Not only did they talk me into changing my existing plan to accommodate adding my daughter & reduce my bill (Which was not reduced btw). Then was told if for any reason if I wanted to suspend the line I could do so & not in cure the $50 monthly charge. So for the past 2mos the line has been suspended little did I know I'm still getting billed. Corp says No.. I'm now on a family plan & even if I suspend it its still $10 monthly. Also if i dont want to pay the $10 i can suspend both lines & no money would occure. Well that's not what was explained & No I need my phone. Needless to say this location is very miss leading in the information they give to their customers. I don't even think they know there own policy & procedures. Only to find that they have done this time & time again to other customers also. Lieing about what type of crdt report will be ran (hard or soft). Anyways let's just say I'm Not Happy & I Will Never Go Back To This Location..!! This Place couldn't get 1 star from me even if they had real ones inside.. So that star above was just so I can get this post up.. #getmoretraining read more

The customer service at this location truly is horrific. It's amazing that some of the staff there ever were hired, and even more so that they still have their jobs. The demeanor of one male employee there with whom I was forced to deal is totally unsuited to customer service: he doesn't smile, he doesn't make eye contact, he doesn't explain what he's doing while you're waiting for him (no matter how long), in fact he barely speaks. Need I say more? It's as though the guy has been lobotomized. Another employee there--female--is the epitome of bitchiness and stupidity. How she ever came to hold any position of responsibility is completely beyond me--but then we ARE talking about T-Mobile, one of the greediest, most incompetently-run companies on planet Earth. If you're thinking of switching to T-Mobile, all I can say to you is, DON'T. They will lie through their teeth to get your business, then treat you like garbage when you are forced to complain. ANY OTHER CELL PHONE COMPANY WOULD BE A BETTER CHOICE. If you're already a T-Mobile victim, however, stay as far away from this branch as possible and go to the one on Milliken in Ontario--they're light years ahead of the idiots at the Upland branch, though that still isn't saying much. But one employee in Ontario detected and corrected mistaken settings in my phone for which the Upland branch was indisputably responsible. read more

They were really helpful when my mom and I decided to switch over from Cricket. Everything took about 15 mins. It is best to have the account number and pin ready or you'll be waiting for a while. We are satisfied with the customer service. read more

Worst service ever. They don't greet customers as they walk in. If there's a whole lot of people inside, they become unorganized. There is no first come first serve rule of thumb here...its whoever goes up to them with a question. I will not come back. read more

One of the worst possible T-Mobiles to ever exist! I have been a customer for nearly 13+ years and was certainly not treated like one! Save yourself some time and go anywhere else. Hell, even go to Verizon. This will definitely be the reason that my contract is ending! read more

Garbage. Me and my wife both wanted new phones and mine was broken so I had to get one. The man would have sold us 2 phones guaranteed but he wouldn't answer any questions and seemed not to care. Went to the t mobile near foothill and haven where there is real service. read more

Quickly helped me solve a mystery problem with my phone. No complaints here.

They only have 2 associates working on a Saturday!! And of course a friend comes in and one of the guys takes time to help them out while you have a line of people waiting!! read more

If there was an option for no stars, that's what I would give this place. Went in to pre-order a Note 4 and when the worker (tall guy with dark hair and beard...possibly Jose. They seemed to have a hard time giving me his name when I called back and was put on hold forever right after leaving. There were two guys working there...must be hard keeping names straight.) realized I wasn't going to keep the service very long (which is how their business is set up...no contracts) he told me he didn't want to complete my pre-order because he wouldn't get his commission! Are you kidding me? Refusing service because they won't make enough commission. Wow. T-Mobile must not provide a great service if their employees are that hard up for cash. Thanks for nothing. read more

Came here the other day with my daughter to upgrade her phone... Excellent customer service experience! The phone upgrading itself took a while but the staff was very pleasant and social so the time went by fast! Kyle was a great help and took the time to show her the new & updated features on her new phone. This is definitely our go to location for any cell needs. It's worth driving the extra bit for better customer service!! read more

Latroye, Jonathan, Alec and Andy are all god sent. I drive from 30 miles away to specifically come from this store. They have helped with every problem I've ever had, every upgrade I've ever done. I have been loyal to this store for the last 8 years, will never leave t mobile and will always come to this store. Highly recommend this store. read more

My family had been with Verizon for 20 years prior to switching to T-Mobile this past March. We were sick and tired of the high costs and poor customer service at Verizon. We have been with T-Mobile for a bit now and I have to say. Best move we have made in a while. The coverage isn't the best but it is pretty damn good. The customer service on the phone, in store, on twitter, and everywhere else they offer it, is supreme to any other phone company that I have witnessed first hand. The T-Mobile reps that I have worked with in this store are fantastic. They love to listen to your rants about your previous carrier and rants about life and they are really nice. When we first switched over from Verizon, Latroye (probably spelt it wrong) stayed like 30 minutes past closing just to help us! He never fussed and he answered all of our questions, explained our new bill, and everything that T-Mobile has to offer. We were really impressed. The T-Mobile reps that we have encountered seem to genuinely enjoy their jobs. Where as when we went to Verizon stores, they gave attitude, impatience, and were just horrible. I love this T-Mobile location but most of them have good employees like this one. I highly recommend the switch to T-Mobile if you are questioning. You will not be let down. read more
