On April 17, 2019 I just happened to walk into this location. I did not know what I was going to get out of it and I did not know the outcome. God brought a beautiful young lady by the name of Erika to my directions to help me out. I explained to her about my situation with my previous phone company. I was trying to see exactly what she could offer us with T-Mobile. We spend a few hours with each other. I must say from the beginning to the end of her service was truly amazing. I was very impressed by her customer service and how much knowledge she knew about her company. She was very respectful. she went the extra mile to accommodate every request and everything possible. I was not a huge T-Mobile fan in the past, but this young lady and this particular location has completely change my outcome on that. I just want to say thank you so much to everybody. All the staffs were very friendly and kind professional and they made you feel like part of the family. I'm looking forward to what else T-mobile has to offer my service and my business. I just want to thank the young lady Erika for being there at that particular time and being at that particular location. This location is very blessed to have her. As a business owner, customer service is very very important and is hard to find at other retail companies. I'm glad I was able to receive an excellent outstanding customer service from her. God bless you! Your truly VERY HAPPY CUSTOMER EDNA read more

Miss Danya and store manager Christopher were very HELPFUL. I had a really tough situation on my hands. I was left without a phone and I was so worried about getting a phone for the weekend. I called the Fontana T-Mobile and I was told that i could come in a receive a temporary phone. As soon as I walked in was greeted by a warm welcome from the staff. I expressed my concern and with in no time I was being helped by the store manager and Danya. Danya truly went above and beyond to help me out and getting a temporary phone. The phone was locked out and she truly spent more then 20 min to help me get the phone reset and in working condition. She was truly patient and really helpful. She truly is a rock star. Thank you Danya for all the help you provide me today. read more

I switched from sprint to t mobile and got two lines, but only got one phone because they did not have the iPhone in rose gold. Did wait about an hour but the associate that helped me was great and made the wait worth it!!!! She made the plans so easy to understand and even helped me set up an email since i had never used one before. I went to the chino location to pick up my second device and the associate was extremely rude and my husband and i decided to go back and wait in traffic and in a jammed packed store to receive Lily's service! She remembered us and our daughters names! She even told me i can call her at anytime w/questions since i am not too tech savvy! We were very satisfied, and will be going back soon to add my mother in law!:) read more

Every T-Mobile store I have been to, has superb customer service. However, this store in Fontana is my favorite! The people are very professional, friendly and knowledgable. I went in yesterday and a young gentleman helped me to activate my new Note 9 just prior to going on his break. He began the process of transferring all my data to my new phone, when it came time for his lunch break. Danya came over to help, whom I have had the pleasure of receiving help from in prior visits. Danya is absolutely wonderful! She always goes the extra mile and above and beyond the call of duty to help people. It is my upmost belief that Danya is an incredible asset to T-Mobile, and I pray she goes far with this amazing company! read more

Walked into this T-Mobile store very apprehensive because I do not like dealing with cell phone Representatives however Christa greeted me with such a great smile and such a great attitude than it changed my entire perception of cell phone retailers. Had issues with my phone and she took her time to figure it out for me. Not into this new age of technology. She made it a fun experience. Soon after I came back to have my son's phone connected.. there is a T-Mobile store 1.5 miles from my house but I choose to drive the extra 6 so I can deal with someone as pleasant as Christa!!! T-Mobile on Sierra and Valley ask for Christa if you want superb service read more

Phone was cracked and needed a replacement as soon as possible before my trip overseas. Saw a t-mobile store from a distance and decided to stop by and see what was in store. As soon as I entered, I was greeted by a lovely sales rep who helped me in what I need. Andrea is her name and she helped me chose the best phone and also helped me switch to a plan to fit my traveling needs. Saved me tons of money and helped me fall in love with my phone. Thank you so much Andrea! Definitely recommend her for anything you need. As humble, straightforward and kind with customer service can be. read more

Just recently I decided to switch over to T-Mobile and the Customer Service was Great. The associate who helped me and my wife out was Christian who was very informative with the phones that were able to meet our needs. He went over the plans and devices which we are very satisfied with. We will continue to go back to there to this location because the Service is Great. I now understand why they are always so busy which is a good thing. read more

I recently visited the store to get a new phone, and unfortunately, my experience wasn't great. The representative who helped us, Victor, seemed to be in a rush and didn't provide the detailed assistance I needed. He mostly responded with 'yes,' 'no,' or 'correct' when I asked questions, which wasn't very helpful. I understand the need to help more customers quickly, but a bit more attention and clarity would have been appreciated. read more

Jose is the shittiest employee there , the kid smells like shit and sucks at his job. We were there when he got cussed out on the phone and I guess it really got to his head when he couldn't focus straight after the call mumbling things and messing our plan up, next time treat people with respect and quit moving things around peoples plans for you to get your gas money for the month. Fire him and get a better employee read more

Honestly best T-Mobile around ! The staffs great ! They have great customer service ! They help you regardless the situation they take thier time explaining things, and make it quick and simple. They simply make being there a breeze and besides that they are great at making you feel welcome ! Personally my favorites are Jhon, and Maria ! However , Everyone else are great too! Including management ! read more

Gustavo was a great help. One of the best customer experience i have received in a while. He answered every question with patient and with a smile i could see under his mask. Very engaging conversation but over all i felt comfortable when we he was helping me with my phone. He went above and beyond for me. T-Mobile need to hire more representative like him! I will definitely be coming back!!! read more

I first came to this store about a year ago, and one of the many things I really like is the friendly staff and all the smiles you get greeted with right when you come in. Ask for Lily, I been coming to her since day one for all my wireless needs. She never fails to amaze me with all her knowledge and her commitement of going that extra mile for me just so that I can leave a-happy-costumer. read more

I have had to visit this store twice in 3 months and I was helped by Danya both times. She made the experiences both times stress free. She was very informed on the product and the current promotions. She was very personable and even liked my mom! lol If the store could hire 4 of her it would be the most profitable store around. I will refer people to go see her specifically. read more

Giving this specific location 5 stars because of Juan. He was so nice & super helpful. I'm not sure exactly what he did but he definitely worked his magic, both my daughter & I walked out of there with the phones we wanted. I was there 2-3 days before & Danya wasn't too helpful. She's very sweet but wasn't able to work anything out . Thank you Juan for hooking us up !! read more

The customer service extended to me by Chris, Joshua and Juan, have been extraordinary. It is so sad to see how low customer service has sunk. So I am very pleased to find employees that both know their craft AND are willing to go the extra mile to help. My hat is off to those three young men who made my last three visits into the store a pleasant experience. read more

Hands down one of the BEST customer service experiences I've ever had!!!!! I was helped by Juan and Tito because my phone was stolen. They turned a very horrible situation into a positive and were extremely helpful. They gave me all the information I needed and even assisted me almost everyday for a week while I sorted it out. YOU GUYS ARE THE BEST!!!!!! read more
