Can i use a regular sim card with a iphone 3gs?

I have a regular sim not a micro or nano. Will it work or will I have to cut my sim?

I think you could. You just won't be able to use the internet if you didn't already have a data plan unless you use Wi-Fi.

Yes. The Iphone 3G, 3Gs took the standard SIm card size. The iPhone 4, 4S took the Micro and the 5 takes the nano.

No.It'll work fine.
