Detailed provider reviews for Tanzania

Airalo

Recommended

Airalo's Tanzania profile rides Vodacom TZ, which is the right pick for any safari itinerary. The 5 GB / 30 day plan covers a typical 10-day trip combining Northern Circuit and Zanzibar without strain. Airalo is also one of the few providers with a smooth activation flow on Tanzanian airport wifi.

Yesim

Best price

Yesim is the budget option and the right call if your trip is mostly Zanzibar with maybe a single short safari. It runs on Tigo here, which is excellent on the islands and in Dar, Arusha and Moshi but weaker on actual game drives. The unlimited weekly plan is the cheapest available if you're working from Stone Town.

Pros
  • Cheapest entry tier
  • Tigo is solid on Zanzibar and in cities
  • Unlimited weekly tier is the best deal for remote workers
Cons
  • Weaker than Vodacom in the Serengeti and Ngorongoro
  • 1 GB tier expires in 3 days

Saily

Privacy-focused

Saily is the NordVPN-built eSIM with built-in ad-blocking and a basic VPN tunnel. In Tanzania the privacy angle is genuinely useful because public wifi at airports, restaurants and Stone Town cafes is everywhere and not always trustworthy. The 20 GB plan is by far the largest single bucket on the page.

1 GB
$3.49 · 7 days
3 GB
$7.99 · 30 days
5 GB

$22.99 · 30 days
Pros
  • 20 GB single plan for heavy users
  • Built-in ad and tracker blocking
  • 30-day windows on every tier
Cons
  • Network choice less optimised for safari camps
  • Slight latency from VPN tunnel

Drimsim

Pay-as-you-go

Drimsim is balance-based with no expiry, useful if Tanzania is one stop in a longer East Africa trip and you'd rather not buy a new plan for each border. The per-GB rate around $4 is high for heavy use but reasonable for short stops, and the same SIM keeps working when you cross into Kenya or Uganda.

Pay-as-you-go
~$4.00/GB
No expiry
Balance never expires
Pros
  • Same SIM works across East Africa
  • No expiry — useful for split trips
Cons
  • Per-GB rate is high for heavy use
  • Top-up flow is clunkier than Airalo

How much data do you need in Tanzania?

Most Tanzania trips are some combination of safari and Zanzibar. On safari you barely use data — you're in the bush, your phone is on airplane mode for most of the day, and what you mostly need is a way to upload photos and check in once a day from camp. On Zanzibar you'll burn more, mostly because the guesthouse wifi is unreliable and you'll tether for everything from food delivery to taxi apps.

A 5 GB plan is enough for a typical 10-day trip combining a 4-day Northern Circuit safari and 5 days on Zanzibar. Stretch to 10 GB if you're working remotely from Stone Town or doing a Kilimanjaro trek with daily summit photo uploads.

Mobile money matters: M-Pesa and Tigo Pesa are the default payment rails for almost everything off the tourist trail in Tanzania. You won't use them as a foreigner, but local operators will — useful context when paying for boda-bodas or village guides.

Network coverage in Tanzania

Vodacom TZ has the widest rural footprint and is the only network with reliable signal at most safari camps in the Serengeti, Ngorongoro, Tarangire and Lake Manyara. Airtel is a respectable second and dominant in some northern circuits. Tigo is fine in cities and on Zanzibar but thinner in the bush.

Inside the major national parks, expect signal at the main lodges and camps but not on game drives in between. Kilimanjaro trekking has signal at the base gates and around Horombo and Kibo huts on the Marangu route — variable elsewhere. The Tazara railway from Dar to Mbeya runs through long signal-free stretches in the southern highlands.

Tips for using an eSIM in Tanzania

Julius Nyerere International (DAR) and Kilimanjaro International (JRO) both have free wifi in arrivals — set up your eSIM before you exit customs because the airport taxi areas are the wrong place to be troubleshooting QR codes. Zanzibar's Abeid Amani Karume airport wifi is more variable, but works long enough to activate.

Local Tanzanian SIMs require fingerprint biometric registration at the kiosk under TCRA rules — a quirk that catches first-timers off guard. Travel eSIMs sidestep this entirely because the underlying line is registered through the international provider, not in your name.

For Kilimanjaro climbers: assume no signal above Horombo (3,720 m) and tell whoever's expecting daily updates that you'll be offline. Most porters carry their own basic phones for emergency comms, but tourist data plans don't work at altitude.

Why eSIM for Tanzania

Skipping the biometric SIM registration is the killer feature. The TCRA fingerprint requirement adds a real bureaucratic step at the airport that travel eSIMs avoid completely. You walk out with working data and zero queue time.

The other reason is Zanzibar guesthouse wifi. The island's mid-range accommodation has a notoriously fragile internet situation — fibre keeps getting cut, generators die during Stone Town's frequent power cuts, and you'll end up tethering off the eSIM for everything from booking the next dhow trip to ordering dinner.

Frequently asked questions

Around the main lodges and tented camps, yes — Vodacom TZ in particular has signal at almost every permanent camp in the Serengeti, Ngorongoro and Tarangire. On actual game drives between camps, expect long stretches with no signal at all, sometimes hours. Tell whoever's expecting an update that you'll only be reachable in the evenings.
Up to a point. There's signal at the base gates and around Horombo Hut on the Marangu route. Above 4,000 metres, expect nothing — no consumer carrier covers the upper mountain. Most trekking companies carry their own satellite comms for emergencies, and you should plan to be offline from the day you leave the gate until summit day plus one.
Yes, for almost everything a tourist needs. Tigo has good coverage across Stone Town, Nungwi, Paje, Jambiani and the south coast — really the only thinner spots are the deep interior of Pemba island. If your Tanzania trip is Zanzibar-only, a Tigo-based plan like Yesim is the cost-effective choice.
No. The Tanzanian TCRA biometric registration requirement applies to local SIMs sold by Vodacom, Airtel and Tigo at retail kiosks. Travel eSIMs from international providers are pre-registered through the provider, so you skip the fingerprint step entirely. This is the single biggest reason to set one up before you fly.
Not on most country plans. A Tanzania plan won't roam to Kenya and vice versa unless you specifically buy a regional East Africa plan. If you're crossing the Namanga or Tarakea border, plan to install a second eSIM profile or look at the Africa-wide plans some providers sell.
