Are you in a building when this is happening? If so, have you tried outside the building?

Have you turned the radio off waited a few seconds, and then turned it on again?

Have you tried a hard reset? With the power on, remove the battery for at least thirty seconds. Then try again.

Did it work previously? What did you do just before it stopped working correctly?

It's new mobilphone.
Bought on ebay, new unlocked.
But when I insert my sim card (t-mobile Croatia) ther is no network. I only have SOS.
Sim card is good, I in this place i have min 80% signal power.
