Sounds like a terrific idea. But help me out a bit, because we don't have a phone at all. How much for one of those phones or tabs? How much for a plan that will get me going on a British Island, a French Island and a Dutch Island?
I'm not being at all argumentative here; I would absolutely LOVE to be able to check the boat while ashore on one of those blustery 35 knot days!

If you buy a phone or pad without phone locking GSM - Wikipedia, the free encyclopedia
, you can use different SIM cards in the same phone/pad.
That way you can buy a local SIM card an put into your phone, that is normally less expensive than using a foreign card locally.
The drawback with multiple SIM cards is that the phone number is tied to the card so suddenly you have many different phone numbers but only the one in the phone/pad will work at a given time.
Often you will find that prepay subscription is easy to buy.
If you buy a phone/pad with built in GPS it will also work without any phone coverage.
And if you want chart you should select a chart that works without internet coverage.
But you should now that battery wont last that long when the GPS is turned on.
