Invalid sim

[Mark68]

My phone is suddenly showing that my sim is invalid, when it was fine 2 hours ago.

I have looked across the O2 website and cannot find any useful help at all.

I have tried phoning the helpline from my landline, and have not been able to speak to anyone as the computer will not put me through.

Without warning, I cannot use my phone and O2 is seemingly uncontactable.

I would appreciate any advice as to how to proceed.

Hi @Mark68 

You can contact O2 via Skype on any of the FREE numbers in this guide. (A guide to Skype is included)

Guide: Coronavirus Community Help and Support 

(You could also borrow a phone or use a landline.)

Best number to call 0800 587 4005

Try turning off phone and remove SIM card.

Give it a gentle rub over the contact chip with your finger then try again for a network connection.

Thank you MI5

I have tried that and it has not helped.

I will keep looking for an answer.

You need to determine if it's a SIM or phone fault next, so try your SIM in another phone.

Hi Cleoriff

Thank you very much indeed for the information!

I have now managed to speak to someone at O2 and they have tried to sort out a solution for me.

Your advice is greatly appreciated.

Unfortunately, I don't have access to another phone to try that.

It is looking like a SIM issue, as my wifi is allowing me to use some elements of the phone.

I appreciate your assistance and advice.
