It should work for data, won't be able to send ro receive calls.Any other opinions?
if someone had an iphone4 didnt have the normal sim for the iphone4 and had a ipad sim, they could use the data only plan from the ipad sim in the iphone4 to do data only and also voip/sip calls for free. the problem is there is no good sip client out on the iphone that does push notifications well.It should work for data, won't be able to send ro receive calls.
I had used Data only SIM on my 3GS many times, i don't see why it shouldn't work with a MicroSIM (from the iPad) on the iP4. You may need to modify the APNs but it should be easy enough.
However I am curious, why would you want to do such a thing?
If you get an iPhone 4 you have to have a data plan, so no work around there, so if you have an iPad with data and then get an iPhone you will have 2 data plans no matter what.
Usually people try to put the IP4 SIM on the iPad since it can save them 1 data plan.
Just wondering, you maybe got really good reason to do this.
