I bought my OP5T used in January - Dual sim is not working and never has - sim 1 always says SIM 1 NOT ALLOWED
Emergency calls only and I have tried many different sims from different providers and the result is always the same.

I have tried resetting network settings and reflashed the OOS from 9.08 pie to 9.09 with no Joy.


Any wisdom about this would be greatly appreciated.

SD 835 does not support dual Sim 4g.
Try only 1 sim in slot 1 and slot 2 and it will work.
