Hi, I know this is an old thread, but I just purchased a Teracube 2e for use on Fido network, and am having MMS issues and am unable to edit APN.
I purchased another SIM from another carrier (LuckyMobile, which is on the Bell network; Fido is on Rogers network), as suggested here, but that didn’t unlock the APN.
This link mentions there will be APN changes in the next SW release to deal with this. Have those changes been made? Do I need to download a later SW? I assume a new Teracube would have the latest SW.
Is my only option to try and root the device? Would switching to a different OS (like LineageOS or /e/) work?
Any other options?
