Tanzania costs less than half what Kenya does for an eSIM, and one extra rung on the ladder is why

Seventeen prices from one seller

Airalo is the only eSIM provider we have priced in Tanzania. Seventeen plans, all seventeen verified, every figure read off airalo.com on 17 August 2026. Saily, Holafly, Nomad, eSIMCard and eSIM Go sell travel eSIMs too; none of them has been priced here, so none of them appears below with a figure attached. That gap is real and we would rather name it than paper over it.

Airalo lists these plans as Tanzacomm. That is the company's own retail label — its Tanzanian product line — and not a mobile operator. Airalo publishes no host network for Tanzania, and publishes none anywhere else either, so nobody here can tell you which Tanzanian network the eSIM roams onto.

The metered ladder

Eleven metered plans, topping out at 20 GB. Six unlimited plans sit alongside them, priced by duration rather than data; they get their own section below.

One rung buys a very large discount

The most useful comparison for Tanzania is not against Europe. It is against Kenya, next door, from the same seller, in the same month.

Kenya's ladder stops at 10 GB and its cheapest gigabyte costs $4.60. Tanzania's carries on to 20 GB and its cheapest gigabyte costs $2.15. That is less than half, and the mechanism is visible in the tables rather than inferred: rates fall as plans grow, so the country that sells a bigger plan reaches a better rate.

The like-for-like version is starker still. The same 10 GB over 7 days is $24.00 in Tanzania and $46.00 in Kenya — nearly double, for what is, as far as anyone outside the company can tell, the same product with a different name on it.

We cannot explain the difference. Airalo does not publish how it prices country by country, and inventing a reason would be worse than leaving the question open. What we can say is that the pattern repeats: Ghana also reaches 20 GB and lands at $2.40, while South Africa reaches 50 GB and lands at $0.98. Where the ladder stops predicts the floor better than anything else in the data.

It is a tendency and not a law. The Dominican Republic stops at 20 GB and still sits at $3.43, so a 20 GB ceiling is no guarantee of a good rate. But it is the first thing worth looking at, and here it explains almost everything.

The unlimited plans, and where they stop making sense

Airalo also sells six unlimited Tanzanian plans: $19.50 for 3 days, $28.50 for 5, $36.00 for 7, $38.00 for 10, $49.00 for 15 and $99.00 for 30.

Three things stand out.

The 7-day unlimited at $36.00 is almost pointless. Ten days costs $38.00 — two dollars more for three extra days. If you were about to buy the week, buy the ten.

The 15-day unlimited at $49.00 sits $6 above the 20 GB plan that runs the same fifteen days at $43.00. That is a narrow premium. If you expect to pass 20 GB in a fortnight — two people on a hotspot, or a phone feeding a laptop — it is the better buy. If you do not, the metered plan wins on price and neither wins on time.

The 30-day unlimited at $99.00 is the one to think hardest about. The 20 GB plan over the same thirty days is $44.00. You are paying $55 more, and at the metered rate of about $2.20 a gigabyte that extra money would otherwise buy you roughly 25 GB. So unlimited only pays for a month if you would genuinely burn through something like 45 GB, which most travellers will not.

What to buy

• A weekend. 3 GB over 3 days at $10.00. The 1 GB plan is $4.50 and worse value per gigabyte than anything else on the ladder.
• A week. 10 GB over 7 days at $24.00, or the 15-day version at $25.00 if your dates might move. A dollar is cheap insurance.
• Two weeks, or a safari trip with photo uploads. 20 GB over 15 days at $43.00 — the cheapest gigabyte in the country at $2.15.
• A month. 20 GB over 30 days at $44.00. Only step up to unlimited if you already know you are a heavy user.

The local SIM, which we have not researched

Tanzania is much cheaper than its neighbour but $2.15 a gigabyte is still well above what domestic data typically costs anywhere. Our honest expectation is that a Tanzanian prepaid SIM bought locally would undercut these plans.

We are not recommending it, because nobody here has checked. We hold no Tanzanian local SIM data — no prices, no operator names, no registration rules, no guidance on where to buy or what to bring. That is a genuine hole in this page, and naming it is the alternative to filling it with something invented.

What we would need to say more

Five of the six sellers we track have not been priced in Tanzania. Until they are, this page can tell you what one company charges and nothing about whether that is competitive. The method behind the prices that are here is set out at how we test; our Airalo page covers the seller across every country we hold, and the cheapest eSIM plans puts Tanzania's $2.15 in the wider ranking — the 23rd dearest floor of the 94, so not cheap by the site's standards, but a long way clear of its neighbours.
