Just wanted to share this experience with everyone here at Pine64. I think this might be very important. Recently I had some problems with my PinePhone on March 1st. The date is important because on this day I could no longer make any phone calls or even make phone calls. I thought it was a software issue, but long story short it appears to be a hardware issue, the modem to be exact.. My rationale for this is because ATT (the carrier I use) shut down all 3g by the end of February, thus for me the problem started exactly on March 1st. Also, I discussed the issue with the ATT reps and their IT department. The IT checked everyone...all was perfectly fine on their end. The reps provided me a new sim card and I got the same results, could not make/receive phone calls (no internet either). The IMEI checks out ok in their database, but upon further inspection they notice that the VoLTE was set to "false". Meaning I would not be able to make/receive phone calls (or internet). Yet strangely enough I can receive text messages. They tried putting in two new sim cards, same result. They put my sim card into the latest iPhone and suddenly the iPhone could NOT make phone calls either. It was using the IMEI from my PinePhone. Then they changed my sim card in the iPhone to match the IMEI from the iPhone and suddenly it could make phone calls. The sim card with the iPhone IMEI number was then placed into my PinePhone and then suddenly my PinePhone could make phone calls! idk, PinePhone users may start having a lot of problems as the other carriers start phasing out 3g and replacing it with new 4g/5g tech. In my opinion I think Pine64 needs to update their hardware for better compatibility. Eventually 3g will be gone and there may be a lot of PinePhone users with no cell service. Could become a huge problem. But perhaps other carriers who already dropped 3g, will fair better with PinePhone...can't confirm that.
