CALL them. They have to do whatever is needed to change the phone, so it is totally useless to ask us.

Get a Nano to Micro SIM adapter - they're like five bucks. Pop it into the iPhone 4, and you're done. You don't need to call anyone.

If the iPhone 4 isn't unlocked (or is on a different carrier than your iPhone 6s), you'll need to unlock it first.
