I have an iPhone on a contract that I want to get rid of. I am planning to buy a new smartphone for full price (from Rogers) or on-line. If I do that, can I just swap the SIM card, or do I have to contact Rogers to have them switch it, etc.
If your are using Rogers sim card on your iphone means,you will be able to swap your sim card from Iphone to your new Smart phone.
If it's different network means,you will need to unlock your new smart phone from Rogers network.For unlocking you can approach your service provider or else try to buy an unlocking service from any one of the online unlocking service provider like TheUnlockArena.com Here you can unlock your phone at low cost.
