Hi Buckwheat2!
We are glad to hear that you are interested in our service. The Samsung Galaxy Tab is a great device, it is actually a mobile phone / computer hybrid. However, we apologize to inform you that this device will not work with Straight Talk. Straight Talk does not support the actual device and it is not compatible with the BYOP (Bring Your Own Phone) Program.
If you have further questions, please email us at ST.CorpResolutionTeam@straighttalk.com. Thank you.
Best Regards,
Sara

I recently purchased an unlocked Samsung 7.7 Tab (P-6800), and I would like to purchase the correct Sim Card for it from Straight Talk along with their $45.99 per month plan, to make a long story short when I get to the purchase page they offer 2 different Sim cards, one is a AT&T Compatible MICRO Sim Card and the other is a AT&T Compatible Sim Card (Not MICRO). Can anyone tell me which one of these I need and will fit in my Sim Slot?.
