No network connection in Spain

[Stoker]

I have an iPhone 13 Pro with an esim from O2 and a physical Spanish Sim. I'm in Spain at the moment but today I am unable to get a network connection for the O2 line. The Spanish line is okay. I've tried switching the phone off and on but it makes no difference. When I try to select a network manually I just get a spinning wheel. Any advice would be much appreciated.

Hi MI5

I'm not just completely sorted at the moment as I'm still waiting for the change to become effective. They said it would take 24 hours.

Hi Cleoriff

Yes I think I will have to take this issue of the Spend Cap totally barring me from connecting to a network up with o2 as they say "You’ll always be able to make calls to O2 customer service and the emergency services from your O2 phone." 

If I had been totally dependent on my phone keeping me in contact via o2 in an emergency situation then I could have been in serious trouble.
