Mint Mobile & Pine Phone

[klick]

An update to help others out:  On 8/1/2020 my wife and I had to go to a bigger city in Tennessee (I live in the boonies of NW Tennessee) so I decided to take the Pine 64 with me to see if just maybe it would connect to the Mint (T-Mobile) cell towers and within 15 seconds it was connect with a full 4 bars.  So much for the Mint website telling me I had good coverage in my area.  So, I tried to call my iPhone X and nothing.  I tried having my iPhone call the P64 and it rang through, but very low volume and very scratchy sounding too.  What was interesting was I sent my wife a test text and it went through, be she couldn't respond back. So, I'm making progress and I called Mint Mobile who will refund my money as I had a 7 days test run after paying for 3 months.  Apparently I need to find a Verizon type plan like Mint as I have very good coverage in my area from my Straight Talk plan, but I don't want to pay that much.  Too bad because I was very hopeful with the Mint plan working.

08/03/2020 I just got my Mint SIM and set it up on UBports CE. Added the APN information for Mint and connected to their network. I am able to send and receive calls but no sound at all on my end or on the receiver's end. I am also able to send and receive texts. I do not see any sound settings specifically for call volume in the UBports setting app.

The volume side rockers do not seem to work when I am using the Mobian distro on a SD card but at least I am able to make and receive calls using my T-Mobile SIM. On Mint and Mobian, I am able to make and receive both calls and texts although the sound quality sounds a little hollow. I did not have to input any of Mint's APN settings when using Mobian but I do not know if there is any carry over of information from the UBport's settings.

Fix for no audio in ubports calls, camera (requires script and latest dev build), and vol rockers in mobian are coming. Give it a little time to get upstream  UvolMan in ubports open store gives you better control over volume settings.

Thank you for the help! Yesterday when I checked for UBports updates it did not show any available but I just now updated from 120 to 124. The Morph browser is working again. I can send and receive texts but calls fail on UBports but work in Mobian. What script were you referring to for the calls and camera?
