Deactivation PAYG sim

[brumble]

I think my o2 number has been deactivated, I tried to send an SMS to someone and it wouldnt go through and then it showed I had no signal, is there any way to get it reactivated as it hasnt been that long since my number was active and the last time I sent an SMS was on March 23rd so it hasnt been a full 6 months since I sent something on this number. I can't call o2 from my number either since I have no signal.

You need to contact O2.
All numbers are in this guide Guide: Coronavirus Community Help and Support 
When you call, you will be asked for the reason you are calling.
Stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
8.00am is the best time to call if you can.
