Curaçao eSIM

Usually not. Curaçao is a country within the Kingdom of the Netherlands, but it sits outside the footprint of a standard European plan because it belongs to a different network region. Pick a plan that names Curaçao directly, or a Caribbean plan that lists the island among its covered territories, and check that list once more before buying.

Download the whole island map before you leave Willemstad, because the north-west has dirt junctions and very little signage. Note the names of the coves you are aiming for and the key turns in advance, fill the tank before leaving town, and tell your accommodation roughly when you expect to be back. Service normally returns once you rejoin a main road or approach a village.

Complete it before you travel on home or airport Wi-Fi; you do not need the destination plan to be running yet, since it only starts counting once the phone attaches to a network on the island. Save the confirmation as a screenshot or file on the device in case you are asked for it before you have signal, then switch the line on after landing.

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
