I was assuming you had already paid for Internet, because how can you live without it? Cell phones, not so much.
If you’re needing to communicate while traveling, especially if you’re not always in a populated, developed area, a cell phone is more than a convenience, it’s a necessity. I’ve done away with the land line and the cable, can get what I want and need from internet and cell phone. Doing away with the cell phone, well, I just can’t see that working for me or for too many others, to be honest. Internet would need to be nearly universally accessible, even in fairly remote locations. That means internet via cell signal. The speed of internet via cell signal is not all that great. I use it in a pinch on the phone. At home it doesn’t cut it. So, I have both.
