Two carriers operate in Tanzania: Vodacom TZ, Airtel TZ, and Tigo TZ. Vodacom TZ wins on overall coverage, while Airtel provides backup in areas where the primary signal weakens.
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 at $6.71/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.

Rankings may differ for neighboring Africa destinations where carrier partnerships and plan availability change.
We ranked 6 eSIM plans from 5 providers for Tanzania across five dimensions: Coverage (25%), Pricing (25%), Speed (20%), App Quality (15%), Support (15%). Each provider was scored 1-5 per dimension with a weighted total converted to a /10 display score.
Scores for Tanzania use our standard weighted formula: Coverage (25%), Pricing (25%), Speed (20%), App quality (15%), and Support (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.
