Can a rogers SIM card work in an iPhone that is with fido?

I know that with different carriers you have to unlock your phone but I hear that fido and rogers share towers and you can use either SIM card

HI no until you unlock your iphone from fido network you can't use it with rogers sim. You can easily unlock your iphone using sites like http://www.theunlockarena.com/apple-iphone/rs1wp9/ they are providing remote unlocking service to unlock all model iphone from network lock permanently… After unlocking it you can freely use it with rogers or any other GSM sim.

  • Will fido unlock my rogers iphone 4s? I have a galaxy s3 which I don't like and my grandfather upgraded to the 5s and I ant to know if fido will unlock his phone since they are owned by the same company and I would be using it with them.
  • Will cutting my sim card work to use as a micro sim card? I just ordered an iPhone 4 and I need to cut the sim card to make it a Micro sim. Will it affect it. I have seen a bunch of video and already have the template it for it. I'm using simple mobile. Do you know if anything wrong happen to it?
  • Will a Rogers SIM card work with a Fido iPhone 4? I'm about to buy it from a friend at work. I called Rogers and the guy said my friend will have to go to Fido and unlock it for $50 bucks. Is this true?
  • What other carriers Rogers SIM card work with? I have an iPhone 4s and is locked to Rogers when I first bought it. I do not want to spend $50 on unlocking. It just seems that Rogers is very expensive and hope that the Rogers SIM card would work with another carrier?
