Hi, I have an older J3 that is currently locked to three. The phone was upgraded to a newer one probably more than a year ago at this stage, so it is unused at the moment, but I would like to have the phone unlocked for when nephews/neices come to visit from abroad, and they will have something to use with a PAYG SIM.
I'd be very grateful if you can let me know what needs to be done.
Thanks.
