[anubhavs343]

I am using Max pro m1, and except jio all other operator sims are not working properly. I am facing internet issues indoor. If i go to terrace all Sims work properly. I have talked to the service provider and all services are enabled from there side including VOLTE.

Please provide the solution of this.....

Hi @anubhavs343
There is a new update for Max Pro M1.
Do update the same, if the issue still persists factory reset your phone once.
If nothing works, Kindly visit the nearest service center:
Due to the lockdown, service centers may not be functional. Kindly call the service center before you visit one.
