Data abroad

[Walk3r]

My son is on a trip to Paris with the school but his o2 network isn’t working so I can’t contact him

He may need to change some settings on his phone.

Some things to try:
Check data roaming is on in phone settings.
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.

Get him to put WhatsApp on his phone, and do likewise on yours @Walk3r - that way, when he is in range if a WiFi signal (cafe or hostel or school), he and you can talk, message and even video call. France, like Germany, is a good way through removing almost all of the 3G infrastructure, and if your son is on PAYG, he will not have access to 5G service (O2 need to reconsider this restriction for their PAYG customers!). Good luck!
