Use as phone and similar tablet options

[aloerose]

Can someone tell me how well the international version works for phone? Specifically, has any one used it with straight talk? Also, are there other tablets that phone use is available on? I have found some tablets on eBay that are non USA and have SIM slots. They claim to have phone capabilities, but I want to be sure this will work in USA, with straight talk. I have an AT&T Micro SIM card brand new from straight talk. I am interested in purchasing an unlocked tablet that I am able to use as a phone. I want to ensure I would get not just data, but also voice.

Thanks!!
