Compatibility List

Photo of Brave Heart battery sticker from OSAKANA TARO on Twitter
There has been a report on the forum that this sticker can bend the pins that
make connection between the battery and the phone: please check your setup
carefully after removing the sticker.
Note
: the EG25 modem
and RTL8723CS wifi/bluetooth do not work without battery
power, even if you are supplying enough power to the Pinephone with USB-C.
Modem and Carrier Support
There is a document about using the modem by user megi here. This is from circa
18 Jan 2020.
Note at this date there is no TL;DR version - the script at the end to disable
the modem before power off is pretty essential to avoid corrupting your modem's
flash memory.
To check if the PinePhone is supported on your carrier:
Search for your carrier on frequencycheck.com
and compare the carrier's
LTE/GSM/WCDMA frequencies to the PinePhone's supported frequencies (listed under
the specifications
section).
