Phone not recognising sim

[Anonymous]

I am using HTC Desire 310 dual (0PA2200).  I lost my Sony Xperia. The phone that I am using is not receiving or making calls. Any suggestions

Is this recent? Have you only just started using this sim in the HTC?

If you have reported the old phone lost to o2 they will have put a block on your account.
You need to call cs to have it lifted http://www.o2.co.uk/contactus

I lost my Sony Xperia that I had. I had make use of available phone on hand. I swapped the sim and inserted in the HTC Phone. I am unable to make or receive calls

but did you report it to o2 and how and when did you sim swap?

Sounds like there is still a bar on the phone. Call customer service to have it removed

Thanks for all your  suggestions. I got in touch with customer service. I guess the barr will be lifted soon

It should be pretty quick and will probably update overnight.

You will need to reboot the phone.....

I Have just bought an Lumiere 550 from O2 and tried to put the iphone sim on my O2 account into the phone but it does not recognise it.

What can I do.
