If you need to stay connected, consider renting a cell phone and/or SIM card from the folks at Telestial.

If you use a US-based cell network like I do (I like Sprint’s plans), you’ll have to pick up a cheap GSM phone on ebay. Ask Telestial for help. Then ask them for a SIM card that will connect to the cell network in your destination country. Odds are, the cost will be prohibitive for anything but emergencies or a daily 2′ check-in. But having the cell phone option will be a great sense of security.
