Hey,
I got a really old but still operating phone about 5 years old

I havent used it for years, but just lost my HTC smartphone so.... I would like to unlock it since my PAYG sim card is expired

I know its an old phone and old thread but I would really appreciate if someone could help me out with it!
Panasonic VS3
Locked for : Vodafone - Hungary
IMEI: 356404000324263
Thanks in advance,
DC
