Cellular data (iMessage, Voicemail) not working

[Anonymous]

Hi all

Got my hands on the new iPhone 5s this morning (an upgrade) and set it up, all has synced very nicely, and the SIM swap worked too so I'm up and running with my same mobile number.

However, my iMessages and Voicemail currently aren't working. I can't connect to a Wifi network where I am right now, so am relying on the 3G / cellular data - but it isn't working. 

First, am I right in thinking it's a 3G / cellular data problem, and if so, how do I fix this?

Has been about an hour since I set the new phone up and have switched phone on and off a few times, but that hasn't resolved it.

Thanks in advance!

Check your apn matches your account settings.

In Settings > Cellular Data > Cellular Data Network, there are no entries...

Try going to settings > general _ about and leave it for a while, do you get a carrier update?

Also try resetting your network settings.

Nope, nothing comes up...

..although I have just had a message pop up 'Could not activate cellular data network: You are not subscribed to a cellular data service"

That message is usually because the apn is wrong (or missing, as in your case).
Have you restarted the phone?

It might be that the sim migration has not fully completed yet so it may come on later automatically.... Just keep rebooting the phone.

Can you send text messages and make calls?

I have turned the phone off then on again, still nothing.

I have reset network settings and that didn't work either.

Yes, I can send texts and make calls

The full migration can take upto 24 hours. I'd try and call 202 if nothing happens in the next couple of hours though. I imagine all the systems are quite busy at the moment with everyone activating new phones and accounts.....
