Can i use iphone 4s bought in thailand in canada?

I have an iPhone 4s bought from Thailand with model number MD258TH/A and serial number C39H66UNDTDM. In a month's time I will be moving to Canada for good. Can I bring my unlocked iPhone 4s and use it there

I think you can use it with something done. But i don't what has to be done.

Yes, as long as it's unlocked you can insert a Canadian SIM card.

Should be no problem at all, as long as its a real iphone and not one of those fakes they sell here.

Sure you can, as long as the system your iPhone uses in Thailand is the same type of system you use in Canada. Almost all phones in Thailand are GSM system phones, as opposed to CDMA and other types. If your iPhone is a GSM phone (which it probably is if you purchased it in Thailand), you will need to use it with a provider in Canada that offers GSM (and the proper frequencies) as well.

GSM is not nearly as widely used in N. America as it is here, but you should have no problem finding a service provider that uses it.

Should be no problem at all, as long as its a real iphone and not one of those fakes ones. I checked the serial number with the iPhone data base and its all good.
