Using new iPhone 5s and old 4s with same SIM

[Marty!]

Hi everyone,

I currently have an iPhone 4s on AT&T. I am considering getting a new 5s (which would have to be subsidized, can't buy out right). If I got a new 5s, could I use the SIM interchangeably with my old 4s? I'd like to keep the 4s for traveling (it is unlocked) and because it is still on iOS6.

Thanks!

Marty!

You could but you'd need to get a new sim card for your 5s and an adapter for the 4s

SIM adapter/converter is the way to go. I used the iPhone 5S nano-SIM in my iPhone 4S while waiting for my iPhone 5S case to arrive 😀

Ah, so they are different size SIMs! Are the adapters readily available? Like from the AT&T or Apple retail stores?

Thanks again!!

You'd have to buy an adapter from a 3rd party. Apple and AT&T don't and wouldn't sell them.

Or, you can do what I did. I ordered a new nano sim and had my provider activate it for the 5S. Took the old sim card and placed the new nano sim on it and cut around it with a razor blade and made this. It works perfectly for when I wanted to use my nano sim in a 4S or other phone.

Awesome! Thanks for the quick replies!

You can easily purchase one on eBay. I did exactly that, and it only set me back $1.78.

I have a similar question: I've upgraded to the 5c and got a new SIM with it, can I use the old SIM on the same AT&T contract with the 4s still and have two phones?
Thanks!

One is a micro SIM and the other a Nano SIM.

No, only your nano-SIM for the 5c is active. You old 4s SIM would have been deactivated.

I think most people missed the actual question though. I think what OP wanted to know is if he could swap the sim back and forth between the two devices. His reasons were not explained, but a good example might be after the exceptionally good battery life of the 5S runs out, pull the sim out and place it into the 4S. VIOLA, a charged phone with the same phone number....
