Phone not recognising sim

[Anonymous]

Just bought a Huawei phone and I've put in the nano sim but it doesn't seem to be recognising it and says the network is unknown. 😞 Help!

Is this a new sim? Contract or P&G?

Have you done a sim swap : http://swapmysim.o2.co.uk/

Just put your old o2 sim in if you have upgraded and it fits.
If not you may have to call o2 CS to get sim activated http://www.o2.co.uk/contactus

This is a new sim on contract

It's a new sim on contract

It should have been activated in store then but call CS and they will do it for you now.

Could this happen if I don't have signal?

The sim needs to be activated before you can connect to the network & get a signal

It says online that the sim should be activated automatically? 😕

You can check for network issues by putting your postcode in here http://status.o2.co.uk/
If it doesn't show any problems you need to go back to the store or call CS as already advised.
There is nothing we can do here to activate it for you, sorry.
