My phone is not connecting to the O2 network

[Kathryn82]

Hi,

I have an iphone XR which has previously been in working order but now does not connected to the O2 network. I can connect to wifi and use whats app and facebook messanger.  I can also use the internet but i am unable to make calls or send texts from my phone and the signal bar is continuously doing some kind of mexican wave.

I have tried a hard re-set and a soft re-set and have spoke to apple on in an online chat who have advised to go in to a store, which i am obviously unable to do atm.

My sim card works in other phones. Is my phone broken or is there something i can do to fix it?

If it is broken how can i get a replacement or get this one fixed without going in to a store?

I have got the exact same issue. Upgraded to an XR from a 6s+, same sim as before and No service in the XR, yet it has perfect signal in the 6s+ 

Hoping this will get a fix asap!

@Elisaroo @Kathryn82 

Make sure you both have the latest firmware and carrier updates on your phone.

Checking via iTunes on your PC is the best method.

No, none of that worked. 

I went into General settings, About and Network and there it said Phone not allowed?

I've started using my old 6s+ now as I am getting no msgs or phone calls due to this, nor could i contact O2 directly to figure this out.

Sounds like a faulty phone then @Elisaroo

I rang O2, turns out they sent me a barred (BRAND new phone). Courier is picking up the barred one tomorrow and dropping off a (hopefully) non barred phone.

Thought that might have been the case.
