I have an Oppo Mobile phone A1601.

The Oppo Mobile phone A1601 I have does not send or receive calls.  All other internet and messages are working.  I have an Aldi sim card which has been tested in another phone and it worked. What could be causing this problem.

  • Yes it was, thank you

Re: I have an Oppo Mobile phone A1601.

Do you have the settings set to 4G only or potentially in a 4G only area?


It supports Telstra 3G band so working for calls but working for data means it is connecting to 4G successfully but isn’t connecting to VoLTE (could be a setting or could be not supported).


Doesn’t look like it was a phone Telstra had so wouldn’t have Telstra firmware where those would have been enabled by standard.
