Modem UBports edition Celluar not working
#1
I've come across a few posts about there being possible corruption of the firmware on the Pinephone modems. Are the only affected ones the one from the Braveheart Editions or does it occur on the UBports editions as well? Im not sure whats the deal with my UBports edition phone. It was not working when using UBports and even when it was updated I still had no cellular working. Then I tried Mobian and still it was not working. I ran the hardware test from a Postmarket OS image and it shows the modem status as ok.

Factorytest v0.49.0
Status: OK
Registration: not registered
IMEI: XXXXXXXXXXXXXXXX   (it shows but Im not posting it)
Firmware: EG25GGBR07A08M2G
Network: FDD LTE, 311480, LTE BAND 13
Signal: -81dBm

Sim Status
Status: Connected
IMSI: XXXXXXXXXXXXXXXX

Call Status
Status: Ready for call
Technology: ...
Number: ...

Im not sure what to make of it, with Mobian and UBports not working with my sim. I have thought if the results from the modem are faulty results.

(Edit 1) My cellular service is from T-mobile and I used a T-mobile sim card.
Edit 2:  Sim card size is micro

Update:
https://www.t-mobile.com/support/coverag...le-network  a link to T-mobile network bands.

https://www.quectel.com/UploadFile/Produ...n_V1.1.pdf   The Quectel modem pdf

Does anyone know if it might have something to do with the Network bands T-mobile uses in the Los Angeles Area?

Update: I installed and used LTE Discovery on a working android phone and it shows in my area that it connects mostly to band 2 and sometimes 66. Band 66 is not supported by the EG-25G modem.

Anyone know how to keep the modem to refuse or stop trying to connect to band 66?
