You have to let go - I got 4G mobile wifi earlier this year, its fast as heck and sometimes when I don't get a signal.. I don't connect to the internet! Can always read a book, or go for a walk.
I'm kind of extreme though; I've been using cellular data almost exclusively since 2001 so its nothing new. I've spent plenty of time out of range. I think that if you are out of range and you need to connect; its time to move on.
Problem is, I can't let go. At least, not all of the time. I'm a remote employee rather than it being my own endeavor, so there's a certain expectation of communication in addition to needing to interface with our various services from ticketing to source control. My ultimate goal is to be able to work from a beautiful place, and once I'm done for the day, to go out and explore it.
No I have a mobile phone for voice calls. In the beginning I used dialup, then GPRS or EDGE directly through the phone (cable and later Bluetooth connection). Then I got a separate device for data, first an ICOM 3G USB dongle which I used for many years but as of this year I'm on 4G, with a Huawei 4G mobile wifi thing.
