Cant switch on sim

[Muhammadashraf]

My sim doesn’t switch on it comes as emergency only. Cannot pay bill through phone or receive a text to pay online either.

If you have no access to any phone, Skype will work for the 0800 numbers Guide: A Guide to Skype 

And set up a direct debit so you don't have this fiasco again... Good luck, @Muhammadashraf.
