Great combination of flexibility and cost

Gives me all the minutes and data I need at an extremely low price. The sliding scales of minutes and data are perfect for an infrequent caller and low-data user who occasionally needs more minutes and data during travel. Quality of service and coverage has met all expectations. A great combination of flexibility and cost.

Tello service is very good, however, very bad throttled internet

Tello service is very good. However, when you reach your 4G of high speed internet, they will throttle your data/access. Although they claim to throttle down to 2G with unlimited data, you CANNOT access the internet and on the occasion you can, it will take at least 10 minutes for a page to load. If you attempt to listen to internet radio, after waiting several minutes to obtain service, it will fade in and out, until you just finally give up. This needs to stop. I even asked about purchasing unlimited high speed internet and was told there was no such thing. You have unlimited internet, but only 4G of high speed.

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.
