Cape Verde

Another one for the travellers on here.

Not been before, so can anybody advise on mobile data while in CV please?

I’ve been assuming that our normal SIMs with roaming would be ok as I thought it was covered by Portugal in a similar way to The Canary Islands and Spain, but apparently not.

I’m guessing the answer is to buy a local SIM, but are they available at the airports or do we have to find a shop somewhere?

Any info/advice gratefully received.

TIA.
