Bonaire eSIM

Both are handled online. The visitor entry tax should be settled before you reach the island, and the marine park nature fee before your first time in the water, since dive shops usually ask for proof before handing over tanks. Save both receipts as files or screenshots on the device, because some entry points sit where the signal is too weak to open an old email.

The park is a multi-hour gravel loop and long stretches have no signal at all. Download the island map first, carry enough water, fill the tank, and check the closing time, because entry and exit are restricted to set hours. Tell your accommodation roughly when you expect to be back, and do not count on phoning for help from inside: on a weekday very few other vehicles come past.

Usually not, because dive days consume very little: the phone spends most of the day in the truck or a dry bag. A mid-size plan covers a week built around maps, messages and photos. The exceptions are editing and uploading underwater video every evening, or using the apartment as an office between dives — in either case, double your daily figure before you choose.

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.
