Whats good and working: latest build.

I am using the UBports CE edition in the US. I used the settings that T-Mobile listed on their site for BYOD. The PinePhone automatically set the APN as Fast.t-mobile.com but it did not pick up the MMSC.  I tried to manually enter the MMSC but the phone would not save it. I set the phone to 2G/3G/4G and tried selecting the "Internet and MMS" option (phone would not save the Internet and MMS option) and nothing changed. I was not able to make or receive calls.

The texting partially worked (outgoing only) so I assume I was connected to T-Mobile in some capacity. I was not expecting full texting parity since the SIM is tied to my Apple iMessages. The phone settings function locks up on occasion so I have to close the settings and reopen. Is there a swipe or option to go back to the previous screen? In the settings, there does not appear to be a save function or a previous screen option/toggle after making changes. I have tried pressing the "v" in the upper right corner and it does not save the changes.

The first time I placed the SIM in the PinePhone I had received a phone call that went to voicemail and I received a notification on the PinePhone. I was able to listen to the voicemail, but the sound was so low that I could barely hear it, even though the phone volume was turned to max.

Wi-Fi works for me and I was able to use the phone as a hot spot. The phone dial pad sounds do not work after the first initial attempt to make a call after a restart.  The time does not appear to be tracking properly. I have already set it and it worked initially but it reset for some reason.

I have also not been able to delete/change/save APN settings no matter what I do. I wonder if that is the cause of the calls issue. Also, is Internet the only option available currently for everybody? Selecting LTE won't save as it always defaults back to internet. Maybe I'm doing something wrong.
