A week ago, my sister gave me her Samsung Galaxy Ace S5830I. She said that she could not call or text anyone and could not receive anything. I looked around on her phone and on the Internet to find the root of the problem. I found that the phone had no IMEI number. I typed *#06#
in the keypad of the phone and a box appeared. It had the words "IMEI" but there was no number under it. When I go to Settings > About phone > Status
, this is what it says:
Network: T-mobile UK
Signal strength: -83 dBm 14 asu
Mobile Network type: UMTS
Service state: Out of service
Roaming: Not roaming
IMEI: Unknown
IMEI SV: 01
I hardly know anything about Android, so could you please explain everything simply?
