Please make sure if call forwarding works or not with the USSD codes(Google) instead of the gui of the rom. Btw: which rom, baseband version and rom version do you have? Maybe volte is causing trouble?
Everything is stock. Non rooted G4. I will share the other details asap. It has the latets OTA by Moto for the G4. How come volte is causing this issue and how to bypass it?
Rom is stock
Google is giving me USSD codes to check IMEI etc. Atleast tell me which USSD code to look for?
You have problems with call forwarding... There are USSD codes for call forwarding like **21*
I called customer support, they said it is already activated. Moreover the sim forwards it fine in another phone.
And if you activate/deactivate call forwarding with USSD codes instead of gui on your device?
There is no ussd code to activate it as per the customer support. He said that I need to activate it via Sim manager and enter a number on which calls need to be forwarded.
It says Call forwarding unconditionally registration was successful. But the result is still the same.
Ok, so if the ussd codes won't work then the problem isn't rom related, cause the ussd codes directly set call forwarding to the home location register of your provider hence its a general problem of your provider.
It worked in another mobile. I put the same sim cards back in G4 and this time it worked. Thanks for your help. When I forward calls from my single sim S3 it forward calls with no notification or something. But when I forward it from any dual sim phone like the G4 the caller gets a message that your call is being forwarded for about 20 seconds and then the call is forwarded. Why is that so?
You can disable all call forwardings with: ##002#
