WIND Mobile SIM cards are now available for free. This will allow customers to sign up for a WIND plan without having to buy a new phone assuming that the one they now have is compatible with WIND’s network.
WIND Mobile asks that you take your existing phone or data stick with you to a WIND Mobile store. They will confirm that the phone is compatible and will set you up so that you’ll be able to leave with everything up and running.
