Longshot but will my old sim work in a new phone

[austinl93]

I had a iPhone 4s until about 5 months ago then got the iPhone 5s. Well it isn't that great so I'm buying a note 3 tomorrow. Since my 4s and the note use the same SIM card size can I use that SIM card on the note 3? Or will it not work since it was previous activated although it was activated by me...

Yes, if the Note 3 is unlocked OR the Note 3 is from the same cell provider.

 

[austinl93]

They both are unlocked and we're both going to be using an AT&T SIM card on straight talk.

Then if it's unlocked there shouldn't be a problem.
