Their phone service is excellent but the used phones they sell are junk

Their phone service is excellent; I have no complaints about it; in fact, I would say it's the best deal on the market and the easiest phone company I've ever used, however, the used phone I bought from them is a complete piece of junk - - they sent me a phone with an almost completely useless battery that won't hold a charge for even two days. Even if I don't use it at all, the battery completely drains down to nearly zero within two days and then takes several hours to recharge. It was a complete waste of money. But since my main reason for using Tello was their rates and service, I still give them five stars. (the phone was a Moto)

Competent, helpful and patient.

I was replacing a land line, dial up, tether on a 2001 XP, a 2004 XP and 2014 Win 7 at lowest usage possible. All worked on WIFI setup and Win 7 on tether also. Previously; $18 ISP, $45 ATT local land line only and $18 for another cell phone. The service I am using from Tello is under $15 versus $81 About 5 calls, each time the people I talked to gave excellent service even when I had made mistakes. Most importantly they encouraged me to wait for the changes to occur. Too much time spent working in 1/10s of a second and have trouble adjusting to seconds of wait. Definitely an error on my part not Tello's service. This was not the normal way most use the service. Interesting the XP units seemed to use about 1/2 that the Win 7 uses. All 3 were operated blocking the trackers, ads and anything not directly related to page accessed. No videos etc. This enabled me to use the computer as an information source only. For me after 2 months about 1.5 GB a month.

Tello has been good in the time I have…

Tello has been good in the time I have used it. Website is functional and to the point. The cell service itself could be a bit better (and my understanding is they are working on improving this), but Tello more than makes up for it with superb customer service - the best I have seen in a long time.
