Dear Ubuntu Touch users
Thank you for your answers.
I asked Tella some followup questions. For 1., I asked how long 4G LTE will be around.
Fyi, their response is
At this time, the timeline for when 4G or 4G LTE will be discontinued is determined by the network operators, not by Tello. Tello operates under a main carrier network, so any changes to 4G/4G LTE availability will follow the main carrier’s network plans. While there is no official date for when 4G LTE will fully sunset, current industry expectations suggest that many carriers will continue to support 4G LTE into the next few years. However, we cannot guarantee how long 4G LTE service will remain active, as these decisions are made by the network operator.
I am leaning toward Oneplus Nord N10 that you recommended. The used Oneplus 6/6T is only $20-30 cheaper than the
used Oneplus Nord N10. And T-mobile mentioned they want to drop 4G and 4G LTE last year. It is a better investment
to buy a 5G phone. Yell if you think otherwise.
