I live in the UK. Before leaving for HK, I tried to enable roaming by texting "TRAVEL" to 23336. When that didn't work, I spoke to someone from O2 support to enable the £6 per day roaming. I got a text message confirmation that this has been successfully enabled. However, I have been in HK for several days now and it is not working. The settings for allowing roaming are definitely enabled on my phone.

Some things to try:
Check data roaming is enabled in your phone settings.
Manually search for another network.
Turn off 5G in your phone SMS Preferred Network settings.
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, links all below for O2 on Facebook ( https://o2uk.co/O2CFB) ,
Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) , they should be able to help.
Good luck!
