My k800 just stop functioning, and it says "inactive sim"

Try changing another SIM card to test it. Place the SIM inside your phone in such a way that the SIM terminals comes into contact with the terminals present in the terminal.

Can send pictures/photos but cant receive

O2 finally cam ethrough with the goods and sorted me out. The problem was not with the phone but with the sim card. It was an old sim card from my previous phone which had "I MODE" on it. Apparently the setting of my sim had to be changed to accept the new software on the K800i!

Insert correct sim card

Un-Clocked is temporary, allows free txt and calls for a few minutes.
Un-Locked from a network is what will allow you to use any sim card on your phone.

Se k800i cant recieve sms

I think the problem is your phone has some settings that disabled your SMS functions so I suggest you to try and put your SIM card in another phone and try sendng SMS. If it works, try Reset Settings from the K800i. If it doesn't work, try changing a SIM card from your service provider.
