Do Android phones require a data connection to work? I'm looking at buying a new phone, the oneplus one specifically(pre-orders open again November 17) and my current phone plan I do not have data, just calling and texting, and I was wondering if the oneplus one works without data and I could just use wifi, or if I would need to purchase a data plan for the phone to work. so it would be as simple as putting the sim card from my current phone into the oneplus one and done? all help is appreciated, thanks.
No. You don't need a data connection plan to use OnePlus One or any android phone for that matter. Calling and texting will work irrespective of internet connection.
However, having a data connection will be useful if you want to use some apps on the go.
