Showing error MM#6

[Erlens]

I've been using my Xperia for a year (bought brand new), but today I've received message MM#6 and can't use phone! I've been reading forum and did what experts told to do (remove SIM, restart, even reset to factory mode), but still showing the same message! What should I do?

He reiniciado reestablecido de fabrica y aun nose como solucionar el problema. Me aparece mm#6 no valido al intentar realizar una llamada aparece reenvio de llamada activado.. Y no puedo configurar desde  configuracion adicional...Ya no se que hacer

I have restarted factory re-established and I still do not know how to solve the problem. I see mm # 6 not valid when trying to make a call appears call forwarding activated .. And I can not configure from additional configuration ... I do not know what to do

I've just run into the MM#6 message and I just got my ultra... But the fix too the problem is this... You have to get the phone registered too the network provider... As longs as it not sprint 😂 but that's it... Fixed my problem and I'm sending you this over the xa1. I'm sure I'm late but this will help others who enjoy the phone

You need to get there phone too the provider and have them switch it to the the provider's services.. If you just put the sim card in... Over the course of a few days MM#6
