My new job at the county gubment has got me seriously lacking connections to the outside world. No personal email, and very little internet connectivity but hey, I can still post on GRM during breaks.
Is there any way of using a 3G/4G device, say, an ipad, or ipod touch, as a cell phone, thru a service like Skype or similar? Basically, as long as I have 3G service, I can call anywhere anytime for free?
Since moving away from home, I rarely use my cell phone, and communicate with friends or family mostly with the occasional call on weekends or through email/txt. A pay-as-you-go plan would probably work best for me, but I'm curious if a 3G device could fit the bill.
