you can pay by paypal or credit card
Will it work with android 4.1.2 ? Also can it work on its own without a phone by just placing a sim. (When I say work I mean will I be able to make phonecalls and connect the web without having a cellphone paired at moment)
Dear, it can't, you should connect with your mobile equipment, then make some phone calls or message, thank you for your inquiry!
