hiya, I'm from Canada and my wife and I will be in the UK starting July 29th. I have received my giffgaff sim card in the mail. Is it okay that I don't activate the cards until I arrive? When I attempt to activate, it wants me to select a plan and pay for it. Since I won't be able to use the SIM card for another 16 days. please advise what my next steps are. I would hate to have the SIMs cancelled in the system as they won't be activated.
