Hi,

My IMEI number is lost. so i can't access any network.
Model: Samsung Galaxy SL GT-i9003
I tried a factory reset
I don't have any efs folder backup.
Please help to solve this problem.
If anyone has any other solution or option to repair or recover my imei number, plz help me.

Take off the back cover. Take out the battery. Look at the label. The IMEI should be on there.

Getting it back into the phone should be the problem.
