Will a PAYG Samsung Galaxy S3 on O2 work with a GiffGaff SIM?
To provide further detail.
I have a two year old iPhone 4s that since it went out of warranty randomly lowers the volume of output. Music/Call/Ringer. This week it has caused me to miss out on some social activities that I would *reallY* like to have attened.
As such, I have decided to replace the said fone and donate it to a family member who is my designated receiver of defunct tech.
The Samsung S3 looks like a nice phone to me spec wise. About equal in power to the iP 4s but with the ability to add in a memory card to hold more music; etc etc. CarphoneWarehouse have the S3 at approx £200 sim free or £160 on PAYG O2 plus a £10 topup.
I currently have a GiffGaff sim with a recurring goodybag and a number that my friends & Family all know. Can I make the O2 phone serve or would I need to pay to unlock it at that point?
