O2 network doesn’t work abroad (Italy)

[MrRobot]

Hi,
I’m in Italy for work and after a sim swap the network stopped to work properly.
I tried everything ( APN, network reset, phone reset etc.. ) but nothing to do. Please help
Help me please

Hi @MrRobot,

I will tag our account advisors @Anonymous @O2Emma to see if they can troubleshoot and check that your sim serial number is correct.

You need to contact O2.
All numbers are in this guide Guide: Coronavirus Community Help and Support 
When you call, you will be asked for the reason you are calling.
Stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
8.00am is the best time to call if you can.
