Not receiving verification texts

[Jh4]

All of a sudden I am not getting verification code texts from my email & Skype & bank which means I cannot log in to them. Have checked my texts blocking list on phone, none are blocked. Got verification text from o2 though no problem. Anyone know what to do?

We've had a few of these recently.

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.
