I bought an iPhone 4 last year, so the fido sim card that was in my old phone became deactived, when I turned on my old phone, it said on the screen "Inactive Sim". I'm traveling to US soon so I wanna buy a prepaid phone card & use it with my old phone, but the fido sim card in my old phone is now inactive so I don't think I can use it with the prepaid phone card (because how am I gonna activiate the prepaid card when the sim card in the phone is inactive)...so I'm wondering how can I activate an inactive fido sim card? Or do I have to buy a new fido sim card (so that it will work with the prepaid phone card)?
