I never have any problems.

I never, ever have any issues with the service Tello provides me. Occasionally the signal from T-Mobile is a little weak in our neighborhood, but that is the fault of the geography of our neighborhood. My wife uses another carrier and has the same issue. I keep telling everybody about the great service and the low, low prices you charge. Thank you, Tello!

Thanks from an old geezer.

I'm not the best example to give you a review because I only use my phone for possible emergencies only. I'm glad I have it and appreciate your fee. Keep me connected. Thank you.

Awesome 24/7 Customer Service

Hello Tello Mobile. Ever since I signed with Tello, I have been very impressed with their 24/7 customer service. Over the last 4 weeks, I contacted them almost a dozen times to get my service running. The frustration I experienced trying to bring my own phone was due to a so called unlocked phone from another carrier. ATT blamed Tello saying they sent me a defective SIM card so I was provided a new SIM card for free. Yet, I could not unlock the phone. We came to conclusion the phone was locked permanently to ATT network. Since Tello didnt offer many new phones, I decided to buy one directly from Samsung. There was no problem installing the SIM card and powering it up. I finally got the Tello service working. Last week I spoke to Nelson Rivadineira. He said since I was not able to use the service during the first month, I could get a refund. I was very pleased hearing that. A few days ago, I called and spoke to Maria. She issued the refund promptly. I have been telling friends about Tello and how I am very impressed with their customer service. Thanks to everyone there for doing an awesome job. Sincerely Dudley Kuboi
