Wife upgraded from S4 to S7. Bought a Nano-SIM card for the S7.
Proceeded to transfer cellphone number and ANYTHING from Micro SIM/S4 to the Nano-SIM/S7
Problem: Wanted to keep same cellphone number to the S4 but TMobile deactivated the S4 SIM card.
Want: Both phones to function/receive calls so friend can use S4 at work and S7 for personal.
T-Mobile DIGITS only work up to S6.
any Android app would fix this?
can someone in T-Mobile re-activate the Micro-Sim for the S4?
Unless both phones are using digits, you won't be able to have the same number active on both devices. You can reactivate the s4 with a new card but would require another line and a new number. You can forward calls from one to the other but without digits, they can't have the same number.
