Yas Tanzania
Yas Tanzania is a sensible fit for prepaid buyers in Tanzania who want short commitments and 5G on a network operator's own service, with an overall score of 9.5 out of ten. Entry pricing starts at TZS 200, and every plan runs on a 1-month contract.

Pros and cons
congstar
Pros
- Entry pricing starts at €2, well under the €9.30 site median, with prepaid billing available through contract, rolling and prepaid.
- No price rise - price stays as agreed, so what you sign up for is what you keep paying at renewal.
- Terms run 1 month, short enough to leave without a long tie-in.
Cons
- The largest reference plan, Allnet Flat L, is a capped data allowance, so constant streaming or heavy hotspot sharing meets a ceiling.
- The entry figure of €2 belongs to a prepaid bundle, so the monthly contract option Allnet Flat S sits well above the €9.30 site median.
- Support reaches chat, phone and help centre, where email is not among the listed channels.
Yas Tanzania
Pros
- Prices start low, with Wakishua plans from TZS 200 on prepaid billing.
- Every listed bundle sits on a 1-month contract, so nothing runs long.
- 5G is available, alongside a network operator's own network rather than a reseller's.
Cons
- Roaming is charged separately, since paid is paid rather than included.
- Billing is prepaid only, so there is no contract or rolling option to compare.
- Service is limited to TZ, so the plans do not travel beyond that market.
Who each suits
congstar
Who it suits
- Households wanting one bill option across contract, rolling and prepaid types, from prepaid to contract.
- Travellers in the EU who want roaming at included rather than paying per use.
- People on the Telekom network who would rather buy through an mvno than go direct.
Who should look elsewhere
- Anyone who needs truly unlimited data, since the congstar reference plans stop at Allnet Flat L; GETESA, listed as a network, is worth reading if you prefer a direct network tariff.
- Those wanting a single monthly contract price, since the cheapest figure belongs to a prepaid bundle while Allnet Flat S costs more each month.
Yas Tanzania
Who it suits
- Prepaid buyers in Tanzania who pay as they go
- People who want 5G without a long contract
- Customers who value a network operator with several support channels
Who should look elsewhere
- Readers who need roaming included in the bundle, since paid is paid
- Anyone wanting contract or rolling billing, as prepaid is prepaid only
- Travellers who need service outside TZ

Questions about each
congstar
How much does congstar cost to get started?+
Entry starts at €2, which sits below the €9.30 site median for this kind of plan. That figure belongs to the prepaid option, Prepaid wie ich will, on a short prepaid billing cycle. The contract option, Allnet Flat S, costs more each month, so the cheapest headline price and the monthly contract are separate products.
Will my monthly price go up when I renew?+
The stated rule is No price rise - price stays as agreed. Nothing in that rule allows the agreed figure to climb, which is the main thing to check before signing a contract option. Contrast that with typical market behaviour, where the €43 site median for a post-contract price sits well above the €9.30 entry median.
Yas Tanzania
What does Yas Tanzania charge for its cheapest plans?+
Prices start at TZS 200 on the Wakishua range, billed on prepaid. The reference plans show a chat bundle with SMS at that entry price, then a data bundle and a larger bundle with minutes, so the same family covers light chat use and heavier data use.
How long are Yas Tanzania contracts?+
The listed plans sit on a 1-month contract, which is the shortest term on the sheet. That suits customers who would rather renew often than commit for a year, and it means a bundle can be topped up again without waiting out a longer term.
