Cannot make calls - Message "Invalid Number" appears.

[Niamh_65324]

I cannot make any calls since I returned to Ireland from the UK yesterday. I can receive calls, and access data. 

When I try to call someone I get three beeps and a message appears on screen "invalid number". They are not invalid numbers but known and regular contacts. I have an active plan and credit balance.

I tried:

• turning it on and off
• turning flight mode on and off
• choosing the correct network (3 3g) 
• moving my sim to another device (same issue, can receive but not make calls)

I contacted support and they said it could be one week for tech team to revert to me. 

Seems like a network issue that came about when I flew and returned to Ireland last night. 

Anyone got any ideas?
