i was thinking about changing my koodo phone from my lg shine which picks up great signal and is an orignial koodo phone and was going to put it on my iphone but my iphone has been updated and it cannot be unlocked for another 2 weeks so i put my Koodo sim card into my rogers unlocked phone i got when i was a pay as you go customer and the service on it is terrible i never get any calls or any signal except for rare times. I'm wondering if i put this into my iphone will i get this problem with service or will it be alright like the Koodo original phone i had before.
