Home carrier roaming charges in Cape Verde can be substantial, often billed per megabyte at rates far higher than a dedicated travel eSIM or local SIM, making it worth disabling roaming and setting up an alternative before you travel.
Quick answer: Disable data roaming on your home SIM before you land, and use an eSIM or local Cape Verde SIM for data instead. This avoids the often steep per-MB charges that home carriers apply for usage in Cape Verde.
