Kenya + Tanzania eSIM Guide (2026)

The Kenya–Tanzania safari circuit — Maasai Mara, then crossing to Serengeti and Ngorongoro — is one of travel's great itineraries. Here's how to stay connected across both countries without overpaying or dealing with border SIM swaps.

Quick Answer

What eSIM works in both Kenya and Tanzania?

Airalo is the easiest option: buy separate Kenya and Tanzania plans in one app and switch between them at the border. eSIM2Fly's Africa regional plan covers both in a single purchase. For a 3-country trip adding Uganda or Rwanda, Maya Mobile's East Africa bundle is the most convenient choice.

Frequently Asked Questions

What eSIM works in both Kenya and Tanzania?

Airalo covers both countries separately in one app — buy a Kenya plan (from $9) and a Tanzania plan (from $8) and activate each when you cross the border. eSIM2Fly's Africa plan covers both countries in one purchase. Maya Mobile also has East Africa regional bundles.

Can I use the same eSIM in Kenya and Tanzania?

Only if you choose a multi-country or regional plan. Most Kenya-only eSIMs (Safari eSIM, Nomad) don't work in Tanzania. Airalo, eSIM2Fly, and Maya Mobile have options covering both countries.

What network is best in Tanzania?

Vodacom Tanzania (partnered with Vodafone) has the best safari coverage in the Serengeti, Ngorongoro Crater, and Tarangire. Airtel Tanzania is strong in Dar es Salaam and Zanzibar.

How do I switch eSIM when crossing the Kenya-Tanzania border?

On iPhone: go to Settings > Cellular and tap your Tanzania eSIM to activate it (deactivate the Kenya one). On Android: go to Settings > Connections > SIM Manager. The switch takes under 30 seconds.

Is there eSIM coverage at the Serengeti?

Yes, at major lodges. Vodacom Tanzania covers the Seronera area, central Serengeti lodges, and the Northern Serengeti near the Mara River. Remote migration areas and fly camps have limited signal.
