Can you just have a texting plan for the iPhone 4s?

I'm interested in getting the iPhone 4s. Is it possible just to get a texting plan or do you need the calling plan too?

Calling and data and texting are required you can't get an iPhone without it. Now you can buy a ipod touch if you have Wi-Fi you can download the texting app for free

Yes, you can use it with T-Mobile texting plan, it is $15 monthly.

No, you have to get a data plan. And an iphone with no data plan is like a car with no seats. Why bother?

You need to buy an unlocked version of it

I think you can use it with any carrier than uses SIM cards even T-Mobile
