Can I unlock my virgin mobile iphone 4s to use with other sim card?

I just want to use my iphone 4s with sim card.

If you are planning to unlock an Iphone 4s, there are ways to effectively do it. You can do it yourself or try to find a software and easy tutorial to successfully unlock it.

I have come across this site which is very helpful

Yes you can, I used to iphonunlocker.com to unlock mine. It is the best software on the market.
