Hello:

You need to restore factory settings of your k800i . your phone default code is 0000, go to setting then select restore setting or factory setting and enter code 0000 .

good luck .

Double check your phone number by calling another mobile and confirming what number comes up on their phone (my sister recently discovered she'd been giving friends the wrong and wondering why they couldn't call her...)!
Then try calling back using the "received calls" list from their phone. If it doesn't work, you'll need to contact your service provider as their is an incorrect setting in their network.

go to settings ---> call barring ---> then click on Data calls ----> cancel .

this should enable sms send and recieve.

I flashed and flexed the set but to no avail, tried a software update but no update was available from motorola. I then went to the Security settings of the set and restricted all outgoing calls and restricted all incoming calls except the phonebook entries. Then I dialed my mobile using a landline which was on my phonebook and my phone started recieving the calls, then after that I allowed all incoming and outgoing calls. This solved the problem. I believe it is sheer luck because I tried that step earlier on the same day but it gave no result.

what you can do is a master reset and master clear on the phone.

when u have the name stored both in phone memory as well as sim memory this happens. try removing any one.
