Welcome to Vodafone Community
Currently roaming in Brazil. Data works fine but I cannot make any outgoing calls to the UK, I have been able to call other countries on occasion. Tried with 00 before 44 and +44, fust three beeps or nothing at all.
Tried turning on-off the phone (OnePlus 5T), and manually selecting networks (problem is identical on both TIM, VIVO and Oi)
I can't call Vodafone easily for obvious reasons.
It's unlikely to be my handset, as it is dual SIM and the other SIM is working fine.
I need 3rd line support but how to get to it?
