I broke my iPhone 5s and got an iPhone 4s. Can I put the SIM card from the 5s into the 4s?

My iPhone 5s got wet and I fried it when I tried to turn it on so it is shot. I bought an iPhone 4s as a replacement and I was wondering if I can put the SIM card from the 5S into the 4S so I wouldn't lose contacts, messages, ect. Has anyone tried it? Will it work?

IPhone 5S takes nano-SIM and iPhone 4S takes micro-SIM. You need a SIM adapter for that.

Something like this: http://www.amazon.com/...009GB6DBO/

You check check Walmart, Radioshack, Bestbuy too.

Not quite. The 5s uses nanoSIMs, the 4s uses microSIMs. You'd either have to get an adapter or get a microSIM with your number on it from your carrier.
