Try restarting without memory card inside.
Try removing battery,and keep it back after 30 secs.

just press the back cover and make a little slide position while pressing downward.

that could be 2 things.. the battery is not good anymore or ur phone needs some cleaning try cleaning the insides of ur phone with clean cotton buds. let it sit and charge for 30 mins and try turning ur phone on again if this doesnt help try replacing the battery with a new one.

it means contact ur service provider,go to nokia care

5130 is a bad option. it will hang and will not solve any of your problems. video playing on this phone also hangs. the sync between audio and video while playing video is distorted.
5130 also has some issues with back cover

dude. Congrats. Your fone is under warranty. Rush to a Nokia Care Centre, immediately and get your fone repaired. This is a common problem with 5310 XpressMusic. Jus take it to Nokia Care centre and they will solve this problem. But i warn you. it will take minimum one week for it tobe repaired. or even more than that.

Hey, try taking off your cell battery, then your sim card. I have T-mobile nokia xpress v3.7
so i took out the battery cell off
then simcard
remove any meomry cards
then put the battery back on, only the battery
turn it back on
if your sending any messages, pictures or anything, erase them uhh i did this cuz it might hve blocked the signal...
but yea, put the sim card back on

Update the software verison of your mobile
