No service

[Larc]

I decided to upgrade my mobile and my O2 account.

Today I received a text message from O2 thanking for my upgrade at 18:22.

on myO2 all the upgrades are showing and the same number is there.

Since I received that message that I don’t have service on my mobile. 
I tried to restart the mobile , tried to remove and reinsert the sim, but nothing.

I am at the moment on holidays in Portugal and the customer service apparently is shut for the bank holidays.

What do you think I can do?

Customer services aren't closed for the holiday. They open at 9am tomorrow. All contact numbers, including calling from abroad are here https://www.o2.co.uk/contactus 

Also try social media if you prefer

you can message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG), hopefully they should be able to help.
