Can I put an iphone 4 sim in an iphone 5c?

I have an iphone 4 at the moment and was wondering if the sim I have will fit into the iphone 5c when I purchase it next week.

Should not be a problem.Ihphone 4 has 3g and 5 LTE. You may want to check the sim is set for lte

No, sim card is much smaller for 5c (it's nano)

It wouldn't normally be a problem except that you may need to check if the iPhone 5c comes unlocked especially if your iPhone 4 has a carrier and to the answerer who said that the iPhone 4 doesn't have a nano sim, it does and this is why iPhones are different to Androids etc.

You can cut them down they still work fine
