Excellent customer service from representative, Daniel Echevarria. He spent the whole morning to ensure that our transition from Verizon to T-Mobile was seamless... And, where there were seams,, Daniel ironed them out. read more

The staff and manager are very prompt and responsive and very attentive to all our inquiries. My husband gets impatient with things about completing transactions and anything that would take hours to complete. We inquired about getting a new phone and a tablet and Emily gave us all the answers we needed. She was patient and the store manager, Scott, was up front as soon as we walked in. We had zero stress and this is the 2nd time I've been at this store. First was with my mom. So anytime we have any inquiries about our services, we go here and it always never disappoints. read more

When your faithful and favorite Yelp correspondent needed help to migrate my files from my Galaxy S22+ to my new S25 Edge, I turned to the San Dimas T Mobile store. Employee Monica was awesome! Despite a queue of customers that ran four deep, she remained unflappable, calmly and steadily helping her customers til it was my turn. Monica efficiently dispatched my file migration project, expertly multi-tasking while occasionally peering over to confirm my files were still transmitting. In the past 21 years of using smart phones, I've dealt with T Mobile stores in Chino Hills and Diamond Bar. With the latter location now shuttered, San Dimas emerged as my new go-to location. read more

Honestly, if I could give 0 stars, I would. I walked in just to ask them how to redeem an offer from the T-Mobile Tuesdays app, and it took like 15min for anyone to even acknowledge I was in the building. And once someone finally approached me, I asked them how to redeem the offer and all they said was "I don't know how to do that, we don't really redeem offers here in store". Okay, thanks for wasting 15min of my time to let me know how fucking incompetent your staff is. This is your store, this is your company; how do you not know how to walk me through something as simple as this? Are you seriously unable to get me someone that has the answers I'm looking for? I get better customer service at the fucking DMV... read more

My usual T-Mobile store in Covina and San Dimas closed, and the Diamond Bar location had a change of ownership. I needed another location and found this Glendora store on Yelp. The store is located in a shopping center, easy to find and plenty of free parking. In my usual hectic and chaotic style, I had several transactions to complete! It was not a problem for Customer Service Rep, Jade! She remained calm and answered all my questions. I was able to get the new Samsung Galaxy Ultra 24+ model. After she transferred my data and contacts, I wanted a new tablet. My current one was only two years old, but clumsy me dropped it and cracked the screen. I will say that this Galaxy Tab A model kept on working for several months after I damaged it. Jade informed that I could get a FREE tablet by establishing a new line of service. I was going to purchase a new tablet anyway, so FREE was a good option. I was satisfied with the service and quality of the products. I also purchased a case and screen protector, just in case and will prolong the life of my new phone. Check out their website or come in to browse the merch and accessories. Don't forget to tell 'em that Rosemary sent ya!! read more

I had a problem with my phone, so I called to see how long waiting times were. Spoke with Jonah, he tells me no wait. I head down, takes him five minutes to fix something I couldn't figure out. Very professional and very nice. Great customer service. Thank you. read more

Thank you Stephanie for making my experience there the best! Upgraded my family's iPhones and had a wonderful experience in doing so, thanks to Stephanie. She was patient, knowledgeable and took her time to address all my questions and concerns. She shared her thoughts and suggestions on which options to go with and made me feel real comfortable with the entire process. T-Mobile is fortunate to have Stephanie on their team. read more

Some visits are decent, but some aren't great. I've come here and was told it would be a 15 minute wait, and then they'd help others who walked in after me. Not sure if there's some sort of appointment walk in service. If there is and they were helping those with appointments, then I shouldn't give a low score based on this. However, one employee told me that aluminum is more durable than titanium. It didn't sound right to me, and titanium is obviously a better material. I still bought the watch, but employees need to know the difference in materials that they're selling, and be honest. However, they are very friendly when I come in and have answered most questions correctly. Just be aware and do your own research when you have questions to be sure! read more

This shout out is to the manager Bree when we came in at 5pm 10/9/24. She helped us, was totally friendly, professional and efficient. We really appreciated her! read more

Customer service rep Cameron acknowledged my 89 year old dad as he walked in the door. Although he appeared to be sitting with another customer, he kindly attended to my dad, fixed the problem in less than 5 minutes, and returned to the other customer. This was effective customer service skills! Thank you Cameron! read more

Walked in & only 1 other customer was there being helped & multiple workers standing around or coming out the back. Was greeted "hi" with their heads down. Stood there for 7 minutes with no one saying anything else. Another customer walked in & same thing. She asked me what was going on & I told her I have no idea. They just said hi with their heads down & never said anything. When she spoke up they said "we said hi" & I told them they didn't even say they'd be right with us or nothing. The worker kept speaking over me & said "I'm giving you the same energy you gave me". She treated me like I was disturbing her by walking into the store. I asked to speak with the manager. She went to the back & came back out saying "he should be out in about 15 minutes" the manager wouldn't even come out to speak with me right away is crazy. For you to have all these workers & barely any customers in the store & to not be helped or at least asked politely to wait is wild. Do better read more

I would give zero stars if I could, I come in to work on the new business select account I opened for my businesses, I am told by the associate that he can't help me because I'm not on the account. When only a few days ago I was assisted by a different location with no problem. So went to the Grand location and magically they were able to help me. Apparently there was a managers meeting so the employees at this location didn't feel like working, they were playing card games and not working. Avoid this location! read more

I came in to try to get my dad a new phone, add a line and transfer a phone number. Mason helped guide us through the process and came up with a better solution for our needs, which saved us a ton of money and made it a better option overall. Mason was skilled, knowledgeable, and friendly to me and my dad. Really appreciated his help and highly recommend him to anyone that needs help at this T-Mobile. read more

I went in today and was attempting to switch out my phone. The staff member who attempted to help was named Briana. Stay clear of her! She was very rude and unhelpful. Ive yet to encounter an associate there like her. Maybe shes mad because she had to work? Either way ya aint gotta be so grump face. I ended up leaving and going to another store bc she was just suck a jerk! Briana I hope you learn to be nice to your customers!! read more

Muy buena atención, nos ayudaron a encontrar varias ofertas económicas para nuestra actualizacion de teléfono, quedé muy satisfecha con el servicio. 10/10 read more

Shout out to Tiffany for helping me upgrade from a iPhone 11 to a 15. She was very polite and helped me in a timely fashion and I didn't feel like she pressured me into anything additional other than a screen protector. Which I'm glad I had cause I actually stopped by today to see if I cracked me screen after less than 2 months and thankfully it was just the protector. Another team member replaced it for free. read more

I usually dread going to cell phone stores because they usually will try to sell you something. I came for a different service and I was extremely satisfied by their professionalism and assistance. Irma was the one who helped me and went above and beyond for me. If you ever need any T-mobile Definitely recommend this place and ask for Irma. She will take care of you. The rest of the staff was great too. 5/5 stars read more

This is the worst store when we came In today it was packed 3 girls an a guy was working. One girl went on break but the other only God knows. One pulled a attitude cause my Mask was falling I work in the industry but the way you talk to people and handle your business really needs improvement. We been in here about a hour now an nothing and nobodies in here horrible because all i need is my screen protector replaced. What does it take to get good customer service anymore I strive on that as a kitchen lead but I deal with people regularly so what did I miss? read more

I walked in to the T-Mobile store, waited there for several minutes. No one said hello. No one acknowledged I was there. Bad customer service. I wasn't sure how long I would be waiting or if they knew I was even in the store , so I just left. Went to another T-Mobile store. They greeted me as I walked in and took care of the situation. I was in and out and 10 minutes. read more

I ordered 2 i phone 14s online and went to the store to ask about them. The employees told me that if i waited a few days they would drop the price of the i phone 15 so i could get that. he said if i didn't pick up the i phone 14s my order would cancel. I got a notification that the phones were ready for pickup on monday, but i then received a notification that my order was canceled. The employees did that on purpose just so they could have us come back and get the i phone 15, shady business tactics. read more

I swear all these places hire uneducated non experienced people so they can pay minimum wage knowing they wont ask for more! I hope they know their losing money and customers and word of mouth spreads and need to start doing a better job at hiring employee's! When you ask simple ? About the difference between plans and the employee tells you to read the paper smfh instead of just knowing and telling me as a paying customer. I could of read it at home. read more

This place is awesome, very knowledgeable and friendly staff. My gf and I were going on a plan together. Prior to coming here, we went to another T-Mobile in West Co where they gave us false information that we had to call into corporate and figure out our plan situation before going in. With that information we did it, but made it harder for us. Fortunately Andy and Tony were able to make the transition of our numbers easy and we walked out with new phones on our own service. I definitely recommend coming here, stay away from 3rd party dealers! Huge difference coming here and will from now on only going here if I have any issues. Thanks guys!! read more

The T-Mobile staff at this location is so helpful! Everytime I come into this store, the staff are more than accommodating. They always find a way to help solve the problems whenever I have questions. instead of saying "sorry there's nothing I can" they really go out of their way to help their customers! Much appreciated!! read more

Got a new phone for free $65mo on senior plan. Jackie the manager helped me, she was fantastic. They get busy but when you come in they greet you and put your name down. Nice store, nice workers, pleasant and take time with you. I called and made an appt first so I was helped right away. I am tech dumb so Jackie really went over and above. I still wont use my phone yet until I know how to work it! Bit intimidating as my old phone was super easy and simple to use but I needed to up grade! Thanks Jackie you were great! read more

I was on hold and on and off the phone with them for 3 hours and still got nothing fixed on my phone. I was transferred to Samsung and still got nothing fixed on my phone. T-Mobile and Samsung are the worst combination for cellular service in the United States. Unable to understand any conversation between their representatives and the customer. Globalization and outsourcing customer service is frustrating and drives people nuts. 100% unprofessional. Since when is a supervisor unavailable to paying customers? When do supervisors hang up on customers. read more

This location is not only the most excellent T-Mobile I've been to, but it is also one of the most well ran customer-service oriented businesses I've had the pleasure of purchasing from over the past year. We have been here countless times to purchase new phones, plans, and accessories - and the entire staff never ceases to provide patient, informative, and quick service. Mason in particular has helped my family and I through many transactions with superb competence and honesty. The team makes it so easy to come back without rolling your eyes about having to go to T-Mobile to get your phone fixed when you have a million other things to do. If you are switching over to T-Mobile I reccommend getting your start with this specific location. If the T-Mobile you go to isn't the most resourceful, I highly reccommend switching over to this location for your visits...I've actually been to all of them in the area, and its undeniable that this store is the best one. read more

Absolutely a joke, women working here could not do anything to help you. Did not help to tell customer on how to convert from Sprint to T-Mobile or help cancel number to account. All they can do is add a line. What the hell can you do to help your customers for your product. T-Mobile your service was terrible!!!! read more

My parents were in here last week to exchange their phones. David and Diane treated them with the upmost disrespect. They were both rude and not very helpful. I will be the first to admit that as senior citizens they're not the most tech savvy but it's David and Diane's job to at least help them to understand. I'm extremely disappointed in how they were treated. Please do better. read more

I'm only giving one star because I can't give 0. Do not go here. They completely lied to me about the plan I was signing up for. Big surprise when I got my bill. Also completely unexperienced when trying to port over our lines from another carrier. We had to go to another T-Mobile-store to have that done for us. Just don't go here. They lied because they had to make a sale. I filed an official complaint and now trying f to see what can be done to fix this issue. Do better T-Mobile!!! This is a fraudulent store. read more

I've got a bunch of great things to say about this store, as well as the company as a whole. First and foremost, been with a competing company for almost 20 years, and the service/coverage around Azusa/Glendora was TERRIBLE. T-Mobile instantly saved me and my family money, and the service was better RIGHT AWAY. Speaking specifically about this store, it's beautiful, and the employees couldn't be kinder or harder working. Very specifically Anthony K. helped me port over my phone numbers from the previous/competing wireless provider, did it quickly and with ease, and took extra time to make sure I understood all the benefits my new T-Mobile plan. Realize this sounds like an paid advertisement, maybe part of it is how UNHAPPY I was with the previous carrier, but can't thank ANTHONY and T-Mobile enough. Thanks! read more

I went here to switch from AT&T to T-Mobile. Alicia was so patient and competent. There were only two people working in the entire store. They had multiple sick calls that day and they were understaffed but she was very patient and went out of her way to help us. read more

If there is ZERO selection, this is what this wireless phone company gets!!! My husband has advance dementia and unable to use his cell phone anymore. I went to T-Mobile store where he opened his account many years ago to cancel the account. I was told that the client himself had to be present. So, we went back with my husband who has no more understanding of what's going on. We were given a phone number and we were informed cancellation of an account is mot one of the services they perform. Like a good customer, we went home and made the phone call to 1-800-937-8997. Spoke to Gav who wanted my husband to get on the phone! I explained to her that he has DEMENTIA and unable to remember anything. She said she needed a power of attorney to cancel the account because I am not in his account. (Thank Heavens, I'm not!) Their service sucks!!! A power of attorney? Seriously! DO NOT USE T-MOBILE!!! They will give you hell if you want to cancel your account. read more

Nicolas was a great help to our family. Helped us save the most money possible and walked us through everything step by step. Ask for him when you go he's extremely professional and helpful! Thanks for helping us out read more

Daniel helped my sister and I with questions and concerns about our plan. His customer service was outstanding and answered all of our questions thoroughly. All of the employees working seemed upbeat and had great customer service. I've been to other T-Mobile locations and received subpar service with unhappy employees, not this location!!! Will return here in the future for all of my service & products needs. read more
