The problem with selling "Tanzania connectivity" is that there are three of them
There's the city — Dar es Salaam, Arusha, Mwanza, Dodoma — where 4G is dense and contactless payments work. There's Zanzibar, which has its own connectivity reality somewhere between resort and developing-economy. And there's the bush, where the Serengeti doesn't have a cell tower for forty kilometres because the Serengeti is the Serengeti. Most eSIM resellers paint the country a uniform green and quietly hope you'll be on Wi-Fi at the lodge. We'd rather be honest: pay for the signal where it exists, plan for the bush.
Roamzy charges $5.73 per gigabyte in Tanzania, billed at $0.0056 per megabyte in real time. No subscription, no expiry on the unused balance, no minimum bundle. One per-MB rate across 193 countries — that's the figure on the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
Realistic usage on a Tanzania trip averages 0.5–0.8 GB per day for a safari pattern (you're in the bush half the time), more in Zanzibar or on a Kilimanjaro descent week. Plan on 0.6 GB/day:
| Trip length | Roamzy ($5.73/GB) | Tourist roaming pass | Local SIM at JRO/DAR |
|---|---|---|---|
| 5 days (Arusha + safari) | $17.20 | $30–80 | $5–15 + KYC |
| 10 days (Serengeti + Zanzibar) | $34.41 | $60–140 | $8–20 + paperwork |
| 2 weeks (full safari + Kili) | $48.17 | $80–180 (often two passes) | $12–25 + 30-day cap |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
A local Tanzanian SIM is cheap and registration is short. For a 14-day safari-and-islands trip, it's a reasonable choice — that's an honest assessment, not a sales line. For a one-week safari starting at Arusha, the eSIM does the same job and is attached at the gate without a passport scan.
What works, what doesn't, where
- Dar es Salaam — 4G/5G across the city, dense LTE on Bagamoyo Road, Msasani, the central CBD
- Arusha and Moshi — solid LTE in town; weakening on the road into the parks
- Serengeti, Ngorongoro Crater rim — patchy. Lodge Wi-Fi covers the building; signal in the bush is luck-of-the-draw and weather-dependent
- Tarangire and Lake Manyara — better than the deeper Serengeti; stronger near the gate
- Kilimanjaro slopes — Marangu and Machame routes have intermittent coverage at lower camps; high camps (Barafu, Kibo) often don't
- Zanzibar (Stone Town, Nungwi, Paje) — solid LTE in the towns; resort beaches usually fine; some boat trips lose signal
- Mafia and Pemba islands — patchy in the towns, weak on remote dive sites
What will I actually use Roamzy for here?
- Bolt and Uber work in Dar es Salaam and Arusha; outside the cities, hotel transfers and pre-arranged drivers dominate
- WhatsApp is where guides and lodge owners respond fastest in Tanzania
- Card payments work in major hotels and chain shops; Tanzanian shilling cash leads in markets and street vendors
- M-Pesa-style mobile money dominates among locals; most foreign travelers won't open an account, but knowing it exists explains why drivers ask "M-Pesa or cash?"
- Camera-translator on Swahili handles signage and menus where English isn't dual-printed
How do I install my Roamzy eSIM?

Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
- No welcome promo that flips on top-up #2. The rate is $0.0056/MB across every top-up.
- No fine-print throttling that surfaces in the middle of a Serengeti game drive. One rate, billed by the megabyte.
- No auto-renewal you forgot to cancel. Balance runs out, the eSIM stops.
None of this is a promotion. Per-MB billing in Tanzania with no expiry is just what pricing looks like when nobody hides anything in it, and you can't discount your way below that.
What if my trip continues across East Africa?
- Kenya — common pairing for safari extensions to the Maasai Mara
- Uganda — gorilla-trek extension via Kigali or Entebbe
