I used the following 3 method:
1. Added new APN, saved;
2. deleted rogers APN rebooted.
3. use system/app mover + APN backup and restore),
A little while the added APN getting erased and back to rogers default 2 APNs(Rogers LTE and Tethering.)
Please help me how to get rid of default Rogers APNs permanently.
Thanks in avdance.
