How Tanzania scored
Our Tanzania assessment evaluated 5 eSIM providers across 3 carrier networks. Vodacom TZ handles 4G LTE routing for all providers in this market. We compared 6 plans ranging from $3.99 to $43.44. Vodacom TZ publishes 4G LTE in Tanzania, which is the tier the network score reads.
Tanzania's 3 networks give providers real carrier options: Vodacom TZ, Airtel TZ, and Tigo TZ. Vodacom TZ is the primary routing partner for all five providers, on published coverage breadth.
The pricing ladder spans from 1GB at $3.99 ($3.99/GB) to 20GB at $43.44 ($2.17/GB). Best per-GB value sits at 20GB for $43.44 ($2.17/GB), our recommended tier for most Tanzania travelers. Holafly adds an unlimited daily option from $2.99/day, which suits heavy data users on trips of 5+ days. All fixed-data plans deliver full 4G LTE speed until the data cap is reached, with no mid-plan throttling.
Vodacom TZ's 4G LTE coverage spans Tanzania's main population centers and tourist corridors. Rural coverage depends on Vodacom TZ's tower density in less populated areas.
HelloRoam scores 9.5/10 for Tanzania, the highest among 5 ranked providers. Airalo trails at 9.3/10. These scores reflect Tanzania-specific conditions: Vodacom TZ routing, 6 available plans, and 4G LTE as the network standard. Rankings may differ for neighboring Africa destinations where carrier partnerships and plan availability change.
What the rubric scores
The rubric ranked 6 eSIM plans from 5 providers for Tanzania on five dimensions: Coverage (25%), Pricing (25%), Network tier (20%), App features (15%), Support access (15%). Each provider takes a 1-5 mark per dimension, and the weighted total is doubled to give the /10 display score.
Where the inputs come from
Scores for Tanzania use the published weighted formula: Coverage (25%), Pricing (25%), Network tier (20%), App features (15%), and Support access (15%). Each dimension receives a raw score from 1 to 5. The composite multiplies by 2 for a 0-10 display scale. Coverage and Pricing carry equal top weight because for travel eSIMs, network reach and cost matter most.
Country-specific adjustments for Tanzania: Unlimited plan availability in Tanzania adjusts the Pricing dimension to weight per-day unlimited rates alongside per-GB fixed rates. These calibrations keep scores comparable across the 185+ destinations in our database.
The scoring spread across 5 providers for Tanzania is 1.5 points (HelloRoam at 9.5/10 down to Nomad at 8.0/10). A spread under 1.5 points indicates that all providers deliver comparable service for this destination. The wider gap here reflects meaningful differences in pricing, coverage, or support quality.

Tanzania Network Landscape
Tanzania has 2 mobile networks: Vodacom (4G), Airtel (4G). Vodacom TZ delivers the strongest coverage combination. All 5 providers route through these carriers.
Carrier Partnerships
Tanzania operates 2 mobile networks: Vodacom (4G), Airtel (4G). Vodacom TZ serves as the primary routing partner for travel eSIMs in this market. All five ranked providers maintain routing agreements with Vodacom TZ. Some providers additionally route through Airtel as a fallback when Vodacom TZ's signal weakens.
Vodacom TZ publishes 4G LTE across Tanzania, and every ranked provider attaches to it rather than to a network of its own. Two carriers give Tanzania travelers basic redundancy. Airtel supplements Vodacom TZ's coverage in areas where the primary signal is weak.
Carrier selection in Tanzania is largely predetermined by Vodacom TZ's dominant roaming agreements. Providers compete on plan structure, pricing, and service quality rather than network access. Coverage scores follow the published partner list rather than anything measured on the ground.
