My iphone 4s says No Service?

I've had my iphone for a little over a month now, on o2. Just this afternoon it came up 'No Service' I ignored it because I thought it was where I was. But it's gone on for 3 hours now. I've taken the sim out twice and turned my phone off&on twice. I can't find any other solution to fix it so I'm asking on here.

Time to get rid of your iPhone and get an Android phone. Okay, try if it works with other sim card. If it does then call up your mobile operator and ask what's wrong. Ask them to deactivate and activate your line then try if it works. If other sim cards don't work on your phone means its your phones problem. Go to the service centre and ask them to fix it.

The network is down, just wait it out until they fix it.

O2 are having major network issues today, see: http://www.digitalspy.co.uk/tech/news/a392859/o2-network-outage-hits-the-uk.html

There isn't anything you can do, they are working on it. Its not your phone or SIM it is O2 and is affecting most people on O2 in the UK today.

  • My iPhone 4s says no service I've had it about 4 months and it's been working just fine until this morning. It's now been a couple of hours where it's told me no service and has refused to let me call or send messages. I tried turning it on and off several times and I've been moving around all morning so it isn't lack of reception. It's getting really frustrating, please help me! Is there anything I can try?
