Alejandra you are such a gem and followed with Umer. Years of dealing with T Mobil..never seen such proper calm and caring hard working crew. Whoever is in charge straight to corporate. Owning my own corp in telling you this crew handled the crowd like turning a bull out of a gate and turning it into a calm pony. Reward this crew please! And anyone that visits it's like a good Resturant. ITS WORTH THE WAIT! read more

I called today at 3:38 PM and spoke with Jaime, who confirmed they had several Silver iPhone 17 Pros in stock. Despite me offering to put one on hold, he told me "not to worry" because they had plenty. After a 40-minute drive, I was met with a very unprofessional experience. While looking up our info, Jaime made a point to ask about the pronunciation of my fiancée's last name, offering a "guess" that was a blatant racist remark--comparing her name to "horchata" when the name doesn't even start with those letters. He then spent 15 minutes aggressively pushing internet and phone plans, only to eventually "help" us by showing us how to use the app--where the phone was listed as sold out. To make it worse, he giggled and claimed he must have sold the last one 15 minutes ago, then mumbled that "nobody has bought a phone today." This was a complete waste of time and a deeply disrespectful interaction. I have no idea how this behavior is tolerated. read more

Issak provided me with something beyond customer service. He knows how to connect with people on a human level so that you know you are truly in good hands. He is an incredible human, not to mention employee. My phone situation was complicated and frustrating but I never had to wonder if he was giving me his best. I'm also grateful for the manager, Alex. Both of them are incredible professionals. read more

Christian went above and beyond and helped me get several phones paid off as well as getting extra money from rebates deposited in my account. I highly recommend Christian to anyone who comes to this T-Mobile store. He will go above and beyond and help solve your problems. read more

Hello to All, This T-Mobile location is great! When you get here ask for Eric Cuevas, he will get you the best deal they can offer you based on your situation. He genuinely cares for his customers! That then translates to really good customer service from him and his team. This store is also clean, structured and very well organized. I normally don't write reviews, but definitely wanted to take the time to write this one! read more

Isaak from the Sierra lakes location was really helpful explaining things in a way that was easy to understand. Very helpful and patien. Enjoyed the whole experience, even as normally a skeptic person read more

Had a great experience today. Aryel guided me through a lengthy and complex system issue. He never gave up and called customer service, headquarters, and spoke with many other reps to help me sort my issue. This isn't the first time I've been provided with great service at this location. I'm very appreciative. read more

Great customer service! Jacob was really helpful and I am happy with my new phone. Thank you

Let me start by saying I'm a Stay at home mom with 2 toddlers. I called to file a replacement request with my insurance they asked if I wanted to jump into a new phone. I said yes they advised me to go into my local store (instead of checking inventory) I get to my local store, unload the 25lb stroller and my 2 toddlers, I set their tvs up so that they allow me the ability to talk) .. this is an entire process to go into a store on my own. I finally get everyone situated and I'm greeted by an employee who looks like she just bit into a sour lemon. fine, I ignore it and share with her my gripe about the phone I have. she pulls up my info and tells me I'm eligible which I already knew. She then tells me I need to come a claim on my phone which I did, and that I am unable to proceed with my upgrade bc of a computer issue. after that she completely checked out, didn't care to help me, didn't care to answer any more questions. she walked over to the door so I could leave. I literally felt like an inconvenience. I then called to see if someone else could help me over the phone and the idiot I spoke to on the phone started out strong, but then went sour real fast. He wanted to share with me why I was wrong in why I shouldn't be able to get my new phone without delay. I then asked for the mgr bc its apparent this store is in need of customer service training. I was unable to reach them and called back another day, he again was unavailable. i left my name and number and have yet to be called. I will not return. read more

Moises was AWESOME!!! Even when the store closed he had a great attitude and made sure we were taken care of. He has great customer service. All of staff was pleasant and helpful, shout out to Ariel. I'm definitely coming back to this T-Mobile when I need to come in the store. read more

For being in the customer service industry. This place does not understand its role in it. Starting with the manager. It reminded me of why I left the competitor At&_. I was with them for 20 years but left because of their terrible customer service. Well this store may as well be the competition. Not sure how they can carry the T-mobile brand still. They made a mistake and I went back to ask them to fix it. The manager refused to speak to me and would only address the concern through his rep while standing in front of me, completely ignoring me. Keep in mind, that it was their mistake, which they refused to address, admit or fix. I had to take it up with corporate, where I filed a formal complaint and received the required assistance. They were able to find the issue and apologized for the store. The issue should have never gotten this far. It could have simply been addressed and worked out if we could have gone about it as grown ups rather than petulant children where we ignore the affected party after causing them monetary damage. Maybe coaching? Maybe training? Maybe caring? Maybe figuring out what working in the customer service industry means? Probably the worst part is that the manager's attitude will now become the employe's culture at this store. read more

I came im here with my wife to simply change my screen protector when my wife bought me the phone she also bought the unlimited screen protectors and i do want to point out that this is NOT the store we bought the phone at but nonetheless we walked in there and no one greeted us we had to walk up them and ask for help and when we told her that we juss needed a screen protector and she puts in my number and apparently couldn't "find" my account. Then continued to say we would have to buy the screen protector online and then go in store to put it in which makes no sense at all and they genuinely all looked like they did not want to do their job and they juss all kept talking within each other read more

I got the worst customer service here. The guy helping me seemed like he wanted to argue with me and lied to me about their prices. I felt horrible even being helped by him. I left and went to the one on summit where I was greeted and helped the way I should be helped. I do not recommend anyone going to the store on Sierra lakes pkwy Worst customer service ever. read more

I came into T-Mobile to switch 5 lines from Verizon on Friday afternoon. I was quickly greeted and assisted by Jacob. I let him know we also wanted to add a new line. He walked me through the process we'd need to take. He was very thorough and knowledgeable. He made sure I was getting all the promotions that were available to me. He also told me to reach out at all if I had any questions or needs. He is definitely part of the reason we switched over to T-Mobile. read more

Christian Soto was extremely helpful. He made our experience very enjoyable. Thank you Chris

DO NOT COME TO THIS STORE!! Evelyn is the store manager and let me just start off by saying, she is rude and no help! She tried telling us that even though we had purchased the warranty for screen protector they are not able to replace it as We did not have the old one on there! Nothing in my warranty does it mention that. She also stated that there is people who abuse the warranty! First off you pay for a warranty to have it replaced 1xbox a month we have had this phone for almost a year and only replaced it 1 other time!!!! when I called T mobile Corp. They did not understand where Evelyn (store manager) sees that on the warranty T mobile Corp. also called another store and they never heard of such a thing!! T mobile was apologetic about the situation.... Please go to the T mobile off summit Avenue they are a lot more friendlier! No hassle! read more

Christian has the best customer service he was very helpful and patient made it a over all great experience

I wanted to take a moment to write a review for a kind gentleman named Luis who works at T-Mobile at Sierra Lakes. He is wonderful. Sometimes, as we know going to a cell phone store is anything but pleasurable. Sometimes, sales people can be pushy, rude and simply be interested in talking you into things you would not do otherwise. I am so pleased to report that Luis is the epitome of a wonderful customer service individual. He's kind, courteous and genuinely concerned with the client. It was clear he was not trying to push a product. In fact, I had no idea that these individuals were commission based relative to how great I was treated by Luis! He is outstanding and he wants his clients to be happy. He also is interested in getting the customer the absolute best deal possible. I would recommend anyone wanting to visit a T-Mobile in this area to visit Luis. I also wanted to add that he is great with senior citizens. My dad who is almost 70 came in with me and I plan on going back to Luis to sign him up for T-Mobile. Luis is a great communicator. My dad is not an easy sell by any means! However, for the first time he is far more willing to upgrade his technology because Luis was so awesome and can help us out! I have read some of these other reviews and I empathize. I have gone into this store before and was less than impressed with staff and service. The culture is a little young. However, I am now willing to go to this location simply to see Luis. Sometimes, I've found with these types of agencies that management and service could be very lacking. Therefore, finding that person is so important and I am pleased to report that I found mine! read more

Moises and staff at the Fontana t-mobile provided outstanding customer service. The process of getting a new phone was fast and smooth. Moises explained everything clearly and answered all my questions. I purchased the Samsung s23 ultra, and the phone is excellent. I definitely recommend this location to anyone looking for a new phone. read more

Wow!! There must have been a miscommunication! That's what I was told by the T-Mobile agent who we will just call Mr. J. I went into T-Mobile on July 12 and thought I pre-ordered the Samsung Galaxy Fold 6. Mr. J said he could order the Fold 6 and I could pick it up on the 24th which I knew was the release date for the Fold 6. I sent Mr. J a couple text messages confirming the pre-order and he called me back and said he would have the phone ready for me on the 24th. Well, on the 24th I received a call and was advised that the phone did not come in. I told Mr. J I was waiting for that phone and was expecting it for my upcoming vacation. He said he would try to locate it, which he did, and that they had it at the Rialto T-Mobile store. I went to Rialto store and was told by their manager that they did have the Fold 6 but it was half the memory that I requested. I was also advised that I would not get the phone I requested which was 512 GB for a while and that the promotion had ended the day before, which I knew. Now I can understand the phone not coming in but what really bothered me was when Mr. J stated that he never pre-ordered it for me. It was a misunderstanding on my part. I advised Mr. J I had the text messages stating that the phone was pre-ordered and he was confirming it. He still denied it and said that he never pre-ordered it. He further stated that if I had pre-ordered it, he would've requested a credit card or some form of deposit. On 12 July, I did upgrade one iPhone 13 max pro to the 15 max pro and thought everything was done on that transaction. That is not good. Customer service. Honesty would' have been a little bit better instead of stating that it was me who misunderstood. read more

TERRIBLE MANAGEMENT from the employee named "LUIS" absolutely horrible. The employee who is bald that is Luis. Horrible manner as if he doesn't want to help. Why are you here working as customer services. It's just insane how he assume that I look like a kid and didn't want to help but instead rushing all the words and said "you ready or not" in a harsh manner. Like damn bro guys you don't want the commission dropping banks for me opening 2 lines. Not only that he assume that I have bad credits. Just crazy how could someone services like that to a customers. Guess you are stuck with t-mobile since you can't find any other job that works for you . LOL stay away from this tmobile it's toxic. Go somewhere else but here. read more

I went to this location twice, this past time I had the worst experience. I had Luis, he was very rude from the beginning and wouldn't even let me talk from the get go. In order to help me, he had to call the service line which he complained about and was very unprofessional, he even told the customer service representative on the line "I've been working here 10 years which is why I'm bald now, this job made me lose my hair." I've been working in customer service for about 9 years and I would never act the way he did. This situation reminded me why I left T-Mobile to begin with. And seeing all the past/recent reviews regarding this same employee I'm surprised management wouldn't step in and control the situation. read more

I spoke with a guy named Christian and he helped me move my phone number from Verizon. I was pretty worried about losing some of my contacts and pictures but he made sure to get all my information moved onto my new iPhone 14 pro max. He got me a credit of 200$ and a netflix account for free. He went above and beyond and was very clear about how my bill would be broken down as well. I highly recommend his services read more

I went in today with my family and got help from Christian who was very helpful, he told us about promotions we didn't know about and saved us a lot of money! read more

the customer service here is gnarly! shoutout to Luis who was incredibly unprofessional, made snide comments and passive aggressive. if you don't like working with people, why are you in customer service? the cherry on top was when he was asking for the the answer to one of the security questions and when we gave it to him, he said it was incorrect and proceeded with "it's okay some of us just don't know how to spell." what is that supposed to mean? do you want the sale or not? also, all of these dudes working here don't wear masks, so just be cautious. read more

I just got done switching over to T-Mobile from my previous carrier and the employees who helped me with the process were great . Awesome customer service.

TL;DR: Go to the T-Mobile store on Summit Ave. Way better service. What a convenient location. Tons of parking spaces around. Also there are some great restaurants around the location so in case you leave the store feeling disrespected you could get Asian fusion cuisine, home-style American, frozen yogurt or pub style food! There's a security guard at this location that stares out into space for hours on end. He doesn't open the door or anything, just stands about with a gun so I guess he's doing his job. MY particular interaction was with the employee "Steve", a prematurely balding small young man with the worst "customer service" attitude I've seen this side of the I-10. I needed to activate a sim card on my partner's phone line. There were notes on the account that T-mobile reps could see that had already been arranged to make it go activation in store. Steve read the notes, and then proceeded to tell me that he would lose his job if he activated a new sim card and new telephone number on this line. WHAT? That's what the notes on the account are granting you permission to do, Steve. He then pointed out an outstanding balance but I was still confused as to why he didn't just move on and activate. Other people activate without paying off their bill. Here's the part where Steve and I begin to irritate each other. I say "Can you call the account holder and explain to him what you told me". He says "No there's nothing I can do". I say "I understand, but can you call the account holder and tell him that? I can't because my sim card is literally in your hand inactive". He says no and re-explains the reason why he will get fired for activating. I say in a calm non-threatening, non-intimidating tone WITH A CURTSY (not clapping out syllables, not shouting, not chicken-necking) if he could call the account owner. He gives me this look as if I just ate his soul because now he has to pick up a landline and call the account owner. Steve talks to my partner, the account owner, and tells him the same thing he told me "Can't activate new lines. You have a balance". The most helpful thing Steve did for me this evening was give me the wifi passcode so I could communicate with my partner on activating the line. Tell me why T-Mobile reps on the phone were able to activate my line and not Steve? This location is garbage in the customer service department and the security guard pretending to be menacing is a waste of space. Go to Summit, they actually care over there. read more

I have frequented this location many many times but several phones and normally have a good experience. I will admit that I already was upset when I walked into the store with the attitude that the gentleman gave me when I told him what was wrong with my phone he gave me the attitude of don't be mad at me because I didn't do it not one of I'm trying to help. It was more excuses and reasons why they couldn't help or he couldn't help as he stared at my phone and stare at a computer screen waiting for the computer screen to jump up at him I picked up my daughters phone and called the T-Mobile 800-number got tech-supportTo have them help me fix my phone then I taught the person at the store how to do a real soft reset. Customer service is not their strong suit and a longer pushing me to the point of Wanting to end my 15 years with T Mobile read more

By far the best T-Mobile I've been to! Was helped out by Felipe & he really listened to any questions we had, he really helped out my sister figure out how much we were paying for each line. I was able to purchase an iPhone 8 Plus, a case & a speaker so quick and easily. I 10/10 recommend their location! Thanks Felipe! read more

I went to transfer from Verizon to T Mobile. All the sale reps were fantastic. Very helpful. I have been there a few times and every time has been good. I did go to San Bernardino and that was a mess. The guy didn't want to help at all. I will continue to go to the FONTANA store on Sierra Lakes. read more
