Welcome to iMore!!

In order to use Cellular service you must have a sim card for that provider for the iPhone to work.

If you wanted to just use wifi no sim card is needed, but your iPhone 4 would pretty much just function as an iPod with wifi capabilities.

Except if it is a Verizon or Sprint iPhone 4 which is a CDMA only device and does not use a SIM card.
