Hi ,
Planning a trip with five full days on the Faroe Islands and then 4 full days in either Copenhagen or Oslo. Unfortunately I don't have the time to lengthen the trip to include all. I don't really like one nights stays if at all possible.

Connections are a bit better from Copenhagen to Faroe Islands.

My main question is SIM card that might work in both or all locations without having to buy one at each destinations.
I know most stateside cell companies have international rates. I'm with consumer cellular and couls add up quickly.
I have WhatsApp which works great back to the states. I'm only wanting DATA and some minutes/text while in my destinations.

Any suggestions , must do's, restaurants, tours at all the listed destinations would be appreciated.

Thanks in advance
