Ah, that makes absolute sense.
It's also the reason I like the tablets that take a couple of sims. If I use the tablet as a tablet, it usually isn't flat, and the clamshell mobile phone is often out of credit and low on battery.
I also might save up and buy the charts necessary to use it on the boat, and perhaps I could set the coastguard's phone number up for quick dial.
