How to make iphone 5 work without a SIM card?

My iphone 5 was formally associated with t-mobile but I got rid of the sim because I no longer had service from it. I then restored my iphone and now it says I need a SIM card. How can I use it like an iPod touch?

Need simm card to work

It needs a SIM to work. Go to T-Mobile and tell them you just need a SIM. You can purchase one (I think they are $10, maybe a little more or less).It does not even have to be activated, you can tell them you will activate it later. Just make sure they know it is for an iPhone so you get the right size.

You can then use the iPhone as an iPod Touch, except it will have GPS.
