Can’t make or receive calls, data turned off, unable to contact support

[Letmepickmyname]

I am travelling currently and my data and phone calls seem to have been disabled.

I can’t call 202 or the international number - it just plays a message saying calls from this number are disabled and ends the call. 

Live chat is obviously useless as it’s always too busy. 

How do I get it fixed?

Some things to try:
Manually search for another network
Turn off 5g
Change your data APN to "mobile.o2.co.uk"
Check with O2 whether you have a roaming bar on your account. Do this via social media
If you message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) , they should be able to help.

@Letmepickmyname If you need to speak to customer service you can download Skype to call the freephone numbers: Guide: A Guide to Skype 

Call +44800 902 0217 or +44800 032 1402 
When it comes to 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.
Say 'Upgrade', 'Lost/Stolen', or 'Fraud' if the suggestion above doesn't get you through.
Best time to call is 8 am UK time.
