i have currnetly changed my sim to the 300 texts and 300 mins with virgin, everything was ok until this evening.....

when i call a number it rings, but as soon as the other person answers my phone automatically hangs up (i hope this make sense)

the last time i was able to call someone was about 16.30 today.

i have 285 minutes left and i am not losing single, and i am still able to dial 789.

anyone having or had the same trouble?
