In a few weeks we go on a cruise vacation. We fly from the USA to
London and spend a couple of days in London (hopefully sleeping off the
jet lag), then on to an 11-day cruise around the British Isles (Ireland
and Scotland, no Wales), followed immediately by a flight back to the
USA.

We'd like to be able to maintain contact with our adult children for
emergency purposes. We have no experience using telephones overseas.

Can someone either make suggestions, or point to some good article that
contains suggestions for using your phone in that manner? We'd like to
avoid, if possible, astronomical charges for that previlege, but don't
have the foggiest notion what to do or what to not do.

if your phone is unlocked and can use a sim, get a local sim there.
you'll pay local rates for calls and you will have a local number.
someone calling you would need to call england.

or, just use it on wifi. be absolutely sure to turn off cellular. also
remove the sim (if it has one) so that there's no accidental
connections.

you can also use voip for international phone calls and not pay much
(or at all).
