Stay online in Zanzibar City — compare the best travel eSIMs for Tanzania.

Zanzibar City’s Stone Town is a maze of narrow alleys, carved wooden doors, and centuries of Swahili, Arab, and Indian trading history, all just a short hop from some of the finest beaches on Tanzania’s coast. Exploring the spice markets and dhow harbour is easier when you’re connected, and the best eSIM for Zanzibar City means one less thing to plan around.

Roaming fees can climb fast on an island trip, and finding a reliable place to buy a local SIM in Stone Town isn’t always straightforward for a first-time visitor. With an eSIM, you buy your plan before you leave, install it in a few minutes, and simply turn it on after landing.

Staying connected across the island

Between Stone Town’s winding lanes and day trips out to the coast, having steady mobile data makes it much easier to navigate, translate, and keep in touch with your accommodation or tour operator.

FAQ: eSIMs for your Zanzibar trip

Do I need to activate my eSIM before I arrive?

You can install the profile ahead of time on home Wi-Fi, then activate the plan itself once you land in Tanzania.

Will it work on both my phone and a tablet?

Most eSIM-compatible tablets and phones can use travel eSIM plans, so it’s a handy option if you’re bringing both devices.

Is it more cost-effective than my carrier’s roaming pass?

Generally yes — dedicated travel eSIM plans tend to offer more predictable, often lower-cost data than standard international roaming add-ons.
