Switching SIM card, from iPhone 4 to iPhone 5

[DinoF]

Me again!!!

Quick question:

My son has a Pay as You Go GiffGaff SIM card in his iPhone 4 and we will be giving him an iPhone 5, very soon.

...shows that an iPhone 4 uses a "Micro SIM Card" and an iPhone 5 uses a "Nano SIM Card".

My question though is this - is the difference, literally just the plastic around the actual gold SIM part?? 

i.e. Would I be able to cut the plastic around the gold SIM on the Micro SIM card, so that it fits into the SIM tray for the iPhone 5, or will I need a new SIM altogether?!

You can cut the sim card down, but it's very easy to damage them if you don't do it right. Easiest thing to do is request a blank nano sim from GiffGaff and do a sim swap. That way you're certain that it will work.

Yes, it can be cut down but must be done accurately.
As he is with giffgaff he can just request a new blank sim card from them which are now triple sims. He can just push out the small nano sim part and activate the sim by logging into his giffgaff account and activating the new sim here www.giffgaff.com/activate
This will transfer all his old sim details to the new one.

I would follow @Bambino's advice @DinoF. Particularly as you are getting a new phone. Sim cards can be cut down but a bit tricky.

Hi @DinoF,

I used to work over at giffgaff, and getting a new SIM and swapping as the guys have suggested is by far the better option. Cutting it is irreversible if you get it wrong and easy to do! I have some mild experience in that haha.

..ok, cheers for the advice guys. Looks like a new sim, is the safest route!!!!

Thanks again.
