Internationally that's a bit more challenging, Yes, there are carriers (T-Mobile) that offer pretty good international cell phone plans but do those phones work as well at home?
I generally add 100MB of data and 100 minutes of voice calling to my Verizon plan each trip. $40 isn't cheap but it's an insurance policy against needing to call home, work, or use some data while out and about.

I know more hotels are offering this as an amenity. Given the (at least locally) cost of cellular data has come down so much, this can't cost the hotel very much and was really a huge benefit for us. Kudos to the St. Regis Istanbul for offering a great amenity to guests!
