Sounds like you need a new sim card which you can only get one delivered to the UK.

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 arrange this for you.

Some things to try:

1 - Reboot phone.
2 - Manually search for a different network
3 - If using an iPhone, change data apn to "mobile.o2.co.uk"
4 - Check with O2 for any roaming bars.

Its not looks like as 2hrs before sim was fine in UK and after 2hrs flight and in different country its not working, very strange for me... hope somebody from O2 will fix it as I dont want be without phone all my holiday just because they incompetence... as support (24hrs support) dont answering.

Have you turned Airplane Mode off? As @MI5 pointed out above - you may either have a bar (contact O2 in this case, links to contact O2 via Social Media below this post) an incorrect (if iPhone) data apn (fix described above or in Guide below), or a 5G SIM that can't find a 5G signal (this you can fix by switching from 5G to 4G or even to 3/2G in your network settings and rebooting the phone). 

Worst case, @SopHiron, as @madasaf1sh says, your SIM is toast (rare if all was cool 2hrs previously in UK).

Good luck!

@SopHiron Customer service in the UK can't fix anything unless you contact them. You may need to have roaming enabled on your account. Instructions on how to download and use Skype to call UK 0800 numbers for free can be found here: Guide: Coronavirus Community Help and Support

You can also reach O2 through the social media links given above.

Its fine now, but its strange as I was switching off phone for any sim card taking off or putting in but now I was take off sim card without switch phone and putting it back and its working fine now...

Rebooting often helps @SopHiron
