Call failure

[Anonymous]

Hi I'm new this so here goes... I have an iphone 5S... It has always worked well but recently I have no signal in my home when I did before and when a call comes in and I answer it it just beeps and says call failure... Really hope someone can help as it's driving me mad...
Thanks

Could be a problem localised to your area? have you checked http://status.o2.co.uk/ to see if there is any work going on on your local masts?

If it happens when you're out and about too, could be a problem with your sim. You can pop into an O2 store and get them to swap your sim for you to see if that solves the problem?

Try

Settings , general , reset , reset network settings.

Try your sim in another phone as a process of elimination.

Sometimes having the SIM card swapped out at an i2 shop where they move your tariff and mobile number to a new one can help.

If the sim works fine then have the phone checked out at a genius bar at an apple shop via an appointment here http://www.apple.com/uk/retail/geniusbar/

And if your a contract customer with wifi at home you could try using Tugo.
