What would happen if I put an iPad sim card in my iPhone Can I put a data only, no voice or text sim card in an iPhone. 

I'm keen to get 4g but I've found the cheapest monthly plan for a nano sim is  £33 for 3GB. This included unlimited text(SMS) and unlimited voice calls.

I make almost no calls, and few text messages.

I was looking at what plans were available for the ipad mini (nano-sim too) and noticed it was half the price: £15.99 for 3GB. Pretty big difference.

Has anyone tried an iPad only sim in an iPhone? 


I'd use iMessage, FaceTime &amp; skype to get round the lack of voice and text, and keep my old iphone 4 as a backup with a PAYG sim.


Notes: 


iPad mini wifi - so I intend to tether 
iPhone 5s(when it arrives)
new 4g networks are coming in December so I don't se the point in locking myself into a 12 month plan, when the price is likely to drop.
I called EE and the guy said I would be unable to make calls or send text messages.

I will try this out and see how I go.
