I have a Teracube 2e 2021 model with Emerald e/os installed and running on Straight Talk’s ATT network. When new at first earlier this year it took a bit of tweaking and I had to add the additional “ims” APN to get calls working, but it’s been fine since.
On December 21st calls suddenly stopped working. When I call out it looks like it’s dialing on the display but there is no ringtone, and if someone calls me it just goes to voicemail. Data and texting works fine. Tried troubleshooting with the carrier but haven’t found a solution. Any ideas?
