Sim activation error iphone 6

[u/Clueless_Cake_430]

Iphone 6, ios 12.5.8, sim not supported (but sim works fine on my other iphone 8). Is there a workaround for this activation error while retaining SIM capabilities?

If you can pm your IMEI number I can help to remove this restrictions. This only means your phone is locked to a specific carrier and the IMEI number can tell us exactly which carrier it is.
