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 192 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.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
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
