been working fine now i cant make or recieve calls on samsung galaxy s
Remove the the battery for a few minutes,that usually helps.
Pop your postcode to check your entwork service:
do you have a signal ? , or checked the o2 site for network issues ?
Check the battery is charged, then take it out, take your sim out and clean it then reassemble. This usually works.
