Stephanie provided exceptional customer service! I visited this T-Mobile store to return my T-Mobile Internet equipment because, unfortunately, the service wasn't meeting my needs. Zoom meetings would constantly cut in and out. I often had to turn my camera off just to get through calls, and the connection seemed to get even worse on windy days. Despite my frustration with the service itself, Stephanie made the entire return and cancellation process incredibly easy. She was patient, knowledgeable, thorough, and took the time to answer my questions and ensure everything was handled correctly. What really stood out, though, was the care she took when applying a new screen protector to my daughter's iPhone 17. I was genuinely amazed watching her work. She applied it perfectly and took her time to make sure it was done right. It's rare to see that level of attention to detail and pride in customer service. I've visited several T-Mobile stores over the years, and I would absolutely make the trip across San Francisco to this location again just to work with Stephanie. She made what could have been a frustrating errand a genuinely positive experience. Thank you, Stephanie, for your patience, professionalism, and exceptional customer care! read more

Solved my issue. My problem was solved by a very competent individual who works at this store. The store is in good location near to good places to shop and eat. So you know if you hit it off with somebody while you were getting your phone fixed at the wonderful T-Mobile store in Walnut Creek and wanted to take them out for a drink and a quick bite to eat you're right there it's perfect read more

Very professional staff ! Adam took the time to walk me through the process of changing service providers. All the staff was cordial and responsive to my concerns. Great experience !! read more

They provide a great service and support. Living on a fixed income, we count on bills remaining stable. T-Mobile has provided that.

I've been to this corporate location many times. I will make the drive as it is the best TMobile, better than any in the Tri Valley. Whether it's to replace a screen protector or upgrade a phone or replace a phone with insruance, they are very knowledgeable and experienced. Great customer service. I always work with the woman there. Her name escapes me at the moment. Was it Alex? I love working with her. There's is never any upsetting in my experience. Street parking in front or metered parking in the strip mall behind the store. read more

Thankful for the guys my parents and I talked to at this location a few weeks back. I wanted to wait for my parents to get back from their cruise before writing this but they're back and they got their phone bill most importantly. Before my parents left, my parents were super concerned about roaming charges on their phones and paying so much money on their phone bill while they were on the cruise. I can't remember their names but we went to this location, they were able to look up my parents phone plan and reassured them they would be alright. They also told them they would need to put their phone in airplane mode whenever they would be on the cruise and use the cruises wifi to connect with people but when they docked and got into town, they would be able to take their phone off of airplane mode. Talking to the guys at this location before my parents went on their trip totally put their mind at ease. And mine, too! Highly recommend coming to this location if you have questions on your phone or need something taken care of. THANK YOU!! read more

I had a great time fantastic. They helped me very much and a T-Mobile store in Walnut Creek. Selena, thank you so much gold star.

Great customer service by Sid! We needed to have my daughter's screen protector replaced and he was more than happy to help us. Thanks Sid for all your help, you don't really find customer service like this anymore! read more

100/10 customer service. Adam and his trainee Rand were super helpful and very knowledgeable!

Earlier this morning while walking my dog, I dropped my mobile apple phone right against the corner of the curb. The screen looked scratched and several crack lines through out. Dropped by the local store, Brian asked me if I needed help. I showed him the phone and quickly assessed if the phone was broke or just the screen protector. Lucky for me, it was just the screen protector. Brian was able to quickly remove the damaged protector and replaced it with a new one. It's people like Brian who are knowledgeable and effective that keep me a happy customer with T~Mobile. read more

I have never walked in this store without a half hour + wait. Currently waiting 20 minutes. One sales person working. Manager in the back. When asked if he/she is aware there are 3 customers waiting, the reply, "I'm sure she knows, its always busy at his time. If its any help we have two more sales persons coming in at 11:30." (1hr 45 min later) When I was finally waited on to have my screen saver replaced, the manager could sell it to me but could not provide a time that the sales rep would be available to put it on read more

My elderly father switched his phone line from another carrier. Everything in transition was going well but he was promised that he would be reimbursed for the buyout of the phone contract. We have been to the location 4 times trying to meet the requirements. We finally had a final paper bill from the other carrier that says "buy out payment" and now it is still insufficient for the reimbursement. Manager S stated that the bill has to specifically say device final payment. In all the times we have gone into the store, everyone has stated that the final bill is what is required and no one stated that the reimbursement was only for the actual device. I asked her to write down what specifically to ask for and still there is no "device" final payment mentioned. It just states that the final bill for phone/phone number is required to be on the same page. While we try again to get the other carrier to meet Manager S's requirements, I am starting to believe that there is no intention of reimbursing at all. That we are being sent on a wild goose chase. Given the reviews for the center I would think that the manager would offer better customer service for an elderly customer who is having difficulty switching carriers. read more

Zero stars for service and overall. Personal completely ignores you, as well as being rude. Its awful.

Always short on staff. Dont bother coming here unless you want to wait an hour (at least). Can't do anything without staff, including getting copy of the bill or paying the bill read more

I'm trying to get a refund on the internet cable box I never used and has been returned. I returned it to the WC store and was told my refund would take a while to be processed as a return. Since then, because the refund still hasn't been processed after a month, I've called the store but was told they can only answer a quick question. So I called the internet 800 number who told me I have to go to the store for them to access my account. The store told me they can't access my account, only the 800 number people can. My impression is that unless you're buying something, they don't care about helping you. read more

After going to a few different stores trying to get my sons phone fixed and thinking it was the phones issue, we ended up purchasing a new phone and after still having the same issue stopped by this location. I believed her name was Alex she was amazing and went above and beyond to assist us with finding out the real issue with the phone/data connection. I have worked in customer service for a long time and now days u don't always see great service but she provided excellent customer service and took her time and really knew what she was doing. I will definitely be coming back to this location for my future phone things. Along with telling people to go this location. read more

I had a really awful experience at the 25 Crescent Drive location in Pleasant Hill, and a really inconvenient and bad experience at the Sun Valley Mall location in Concord. I'm not going to go into detail about it here, but you can read my other reviews about these locations if you care enough. In any case, I was on a needlessly long and arduous journey trying to get my problem fixed. All you need to know is that the Walnut Creek T-Mobile location at 1345 South Main Street solved my problem, and did so with the utmost amount of respect and cordial professionalism. As far as I am concerned, the other stores in the area should be looking at the Walnut Creek location and taking note. They know how to treat a customer, with polite and respectful efficiency. read more

I would like to provide a beyond excellence review for Tyson at the TMobile Walnut Creek Store on 10/27/25. Tyson helped my Mother (80 years old) and I to switch carriers (from ATT) and set up our phones and even managed to help my Mom buy a new Samsung watch which she needs at this stage of life. He spent extra care and time with us to not only handle 2 questions at a time, set up our phones but also to provide an environment of trust. He deserves some credit on how he handled our needs and ensured us that TMO was the best carrier to be with. Please also not that Stephanie was amazing and she was the one that told us they would be ready for us! We will be visiting again. read more

Tristan was extremely helpful with switching me over from Verizon, ordered a new iPhone and set up my new accounts in a very fast manner. All of the employees were very kind. Store was clean. No wait. Great customer service overall. read more

Sid was absolutely amazing! Thank you to whoever hired him, you truly do your store and myself a favor in doing so! I normally don't enjoy going to the phone store and avoid it until completely necessary (I mean the last time I had gone was 6 years ago! And I had been walking around with a cracked screen protector for longer than I'd like to admit), but thanks to Sid I had a wonderful experience! He was very patient and helpful, I also never felt pressured to purchase anything I didn't think I needed. He was so friendly and we had great conversations during any times we had to wait for things to load or process. I even had a few silly corrections needed on my account and he made sure both were done even though it took a few hoops to jump to get it fixed (he did not make it seem like an inconvenience at all!). I got set up completely with my new phone, he made sure my screen and lens protector was put on absolutely perfectly, and that everything was completely transferred over so I was able to leave confidently knowing everything was ready to go on my new phone. I literally left the store in a better mood than I came in, not because of the new phone, but because of the wonderful experience I had with Sid. I truly cannot say enough how much this meant to me! I also want to note the store was clean, had a good variety of items, and everyone else working there was very kind and helpful! All around highly recommend this T-Mobile shop and will actually be back if I ever need anything for my phone, as well as just to say hi! read more

This was my first time at this T Mobile location. I was there with my brother who was having issues with his apple watch. Adams, Tristan, and Tyson triple teamed the problem and got it resolved. I was absolutely impressed with their professionalism, problem solving, and teamwork to deal with the issue at hand. Not once did they ever make us feel like we were incompetent or that they were all knowing. We both actually felt good after leaving the store. That is the reason I decided to do a review on yelp (something I VERY rarely do), because great employees should always be recognized. And for inquiring minds this is not a fake review nor payed for, just respect for First Class / 6-star service. Thanks fellas, much appreciated! read more

Just switched our phone service which it turns out is very time consuming! Luckily we ended up at this store! Employees are awesome and patient! Tristen was so amazing getting new phones and transferring all of our data. I cannot tell you how pleased we are with this store. Check out the good trade in values they give you. Evelyn is also very knowledgeable, patient and helpful! read more

Adam was so helpful and friendly and informative. He helped us add a family member to our plan and come out ahead! 100% go to the WC T-Mobile before any other location. I'd give 6 stars if possible. read more

I recently switched to a new phone and new number. I was made to feel very welcomed and at ease while I asked many questions to make sure I was getting the best deal I could and that I understood what I would be agreeing to. They made the process effortlessly for me. 10/10 I recommend. read more

My salesperson was Tristen. He devoted much time and demonstrated much patience and knowledge whilst always advising us with our priorities in mind. This is the first time that I have found a person who would make me show some network faithfulness, and it will certainly mean that I will no longer dread walking into a T-mobile - in fact, I would happily let him guide me. His positive energy, genuine approach and ability to listen with care were appreciated, necessary and stood out. read more

Went in to upgrade my phone a little over an hour before closing. Jared helped me out and was absolutely amazing. Helped me decide what color phone and what case to get as well even though I was very indecisive. Never once felt rushed but was in and out in less than an hour! read more

I hope every T-Mobile customer gets a Walnut Creek location because they are the greatest team in my opinion always quick fast and very friendly. I always leave T-Mobile Walnut Creek location feeling like a valued customer care, detail and patience whenever I need them means a lot. read more

We went to this store a few times and will visit again. There was a staff member named Joahan who helped us a lot and even though the problem with our phone was hard he still helped us solve the problem and he did. And we came back and remembered us and helped again.This store is the best! read more

I came in on a Wednesday afternoon to look at phones after I finally relented and decided it my old Samsung was well past its prime. Vanessa helped me right away despite there always being customers and pointed me in the right direction and even saved me a couple hundred dollars on the trade in despite me not wanting an iphone or even the latest greatest Samsung. Joahan was also very helpful, helping me with some questions. All the staff were friendly attentive and professional, even when the crowd built up and thats rare to find in a lot of stores and especially appreciated when dealing with the phone that its so hard to function without. They made sure to communicate throughout the process and showed me they wiped my old phone after having me verify the new phone had everything I needed which was a nice touch and easy to miss in this process. read more

The most inconvenient part of asking to speak with the representative over the phone is option with very courteous and respectful towards me and generously my current bill is monthly recurring charges and counting and checking for expediters so she's checking my mobile service and home internet service and watch line and gateway home internet service center has been a modem for home service that was never used or taken out of the package so I have been over charged read more

Austin is great! Very helpful and friendly!! He made sure to help us with everything we needed!

We went in on Sunday to purchase an item for my daughter! Even though they were busy, everyone was courteous, fast and efficient. We are very happy with our purchase. Also kudos to T-Mobile for incredibly fast shipping. read more

Colin and Adam were the very best at helping me upgrade my phone yesterday! They took such great care of me and my kids while we waited and Colin was so eager to help and incredibly knowledgeable about all of the products and went above and beyond to help with a million other iPhone related questions and he did it all with a smile and even sacrificed his lunch to help us ! Awesome people overall and awesome examples for my children of how to be great workers and showed what it is to have pride in what you do! Way to go guys! We will be back! read more

Friendly staff. Came here for my upgrade. Unfortunately they didn't have the phone I wanted but was able to help me find a place. Not only were they friendly, workers here held a great conversation. read more

Don't go to the store they are not open when they say I don't know if they even open at all it's 10:40 in the morning the sign says they open at 10 o'clock and so does online. Nobody is picking up the phone and they are very much so closed. Nothing is more annoying than sitting in front of a store waiting for it to open and nobody is opening it and there's nothing on the door saying why they are closed. read more

Poor customer service. Failed to acknowledge all of the customers to service their needs. Instead of taking the names and numbers of customers that look like you, make sure you at least say Hi to those that don't fit your status. How can I help you! It makes people feel welcomed. We have a wait right now but I would be happy to take your name and number. Advising the customer of your status and provides them with the option to stay or leave. Funny how some got service and others didn't get a Hi.‍ read more

i came in after having a really hard day with personal matters and rasha welcomed me and gave me all the information i needed to know and literally saved me a lot of money and helped me get a new phone at an affordable price! she was so sweet and understanding and had such a wonderful personality. if you want someone that knows what they're talking about ask for rasha! sweetest woman you'll ever meet! read more

I had to take a star off for their lack of queuing system. It's 2022 now, get your ish together T-mobile. I came on a Monday morning and all the associates were tied up with customers. One of the associates had to pause what they were doing with a customer and check me in. They took down my name and number but their queuing system is all internal. It would be nice to get some reassurance and ETA via text message or t-mobile app that I was successfully checked in and in the queue. All the other competitors have some form of system. I waited about 20 minutes to get serviced which is fine. Rasha was very good, friendly and detail oriented. Before we sat down she made sure to disinfect the table. During our interaction she respected our distance and also stopped a customer from taking off their mask to drink from the water fountain. Thank you for respecting Covid-19 protocols. She also made sure I was up and running before ending the transaction. I highly recommend working with her if you get the chance. For management: have a dedicated person at the front checking people in. Invest in some Queue Management Software, you're a fortune 50 company and the 2nd biggest carrier in the states. read more

Joey, Adam and another young worker he had longer hair and a beanie I wish I got his name too! They were AWESOME, they actually cared enough and took their time to help me with an issue with my phone. The most nicest, sweetest people I've ever met and they've done a great job. Great great great customer service. Thank you guys so much I really appreciate it! read more
