Where did yiu get the iPhone from.

If in contract phone O2 on 202 to ensure your on idata settings.

On the iPhone hold down the Sleep/Wake Button and Home button together until the Apple Logo shows. Then On seeing this Apple Logo release both buttons ,and the iPhone will reset , which has been known to clear most glitches.

Other options are :

Settings -> General -> Reset -> Reset Network Settings.

Check your masts http://status.o2.co.uk

Can you try your SIM card in another phone as a process of elimination to see if it's indeed the ohone or network.

Sometimes a sim swap helps.

Any O2 HighStreet Store can perform the swap in store (if on Contract please take some Photo I.D just incase), or a person can take the SIM card home or request one via O2 Customer Services. 202 for Contract. 4445 for PAYG. 8002 for Business -> http://www.o2.co.uk/contactus

Sim Swap link -> http://swapmysim.o2.co.uk Or text SWAP to 20220

Be sure to ask for an Account Specific Blank SIM card as Contract and Pay As You Go versions hold different information. And please take some Photo ID for Contract Sim Cards just incase your asked.

The Service will stop on the original SIM card which indicates the swap has started. Turning the phone Off and On , or if applicable switching airplane mode On and Off ,with the new SIM card in every 20 minutes or so will typically help the connection to settle.

You could also make an apple Genius Bar appointment as might be a hardware issue.

Do Apple sink to the depths of looking at discontinued models?

The cellular data message refers to your O2 data connection, so your phone is not trying to connect to wifi, so your phone is not connecting to any of your data connections. If the phone is an O2 phone the reset mentioned should fix it, if not you will need to do the settings manually. That is assuming you already have data provisioned on your number. As for the wifi it can be your phone or the wifi...I would pair up the connection from scratch... If u r not getting anywhere with all of this try another sim that you know can connect to data on a different phone. That will show if the phone is the problem or the sim card. Hope to helps!
