I downloaded the app TextmeNow and I'm able to send and receive telephone calls and my tablet has it's own number, and I'm able to send and receive text messages. I think there may be a trial period and after that it's $2.99 a month or $29 a year. You have to use your Bluetooth or earphones when talking on your tablet and you also have to be connected to Wifi. The downside is that your tablet can't be in sleep mode or you won't receive your phone calls, but you can retrieve voice messages. Hope this helps! :)
