I have a Samsung S8 and my wife has a S10. We recently moved to Tesco mobile and I have tried to extend the ringing time on both phone using the code **61*901*11*30# On both phones I get the same error message
"Call forwarding when no reply for All Speech Services Connection problem or invalid MMI code"
I have tried various different codes and get the same message. Tesco have now told me that a recent update from Samsung, to all Samsung phones, prevents you from extending the ringing time unless you disable your voice mail. I find this very hard to believe so can anyone confirm this? Does anyone else have a Samsung connected to Tesco/O2 and have managed to extend the ringing time without disabling their voice mail?
Any help would be appreciated.
