Someone and I are thinking of trading phones and I was wondering, would just trading phones and then switching Sim Cards be all I need to do to complete that? Anything else need to be done? They are Samsung Galaxy S2X and S3.
The S2 and S3 take different sim cards so if you have the S2 and want the S3 you can either get a template online for cutting your current sim OR go by a micro sim from any koodo shop for about $10 plus tax.
As long as both phones are unlocked or locked to Koodo, the only issue you'll have is the S III uses a micro SIM card while the S II X uses a regular-sized one. So you'll need to either get a smaller sim card or vice versa activated on your account.
