Best eSIM for Unlimited Data in 2026
True unlimited eSIMs are rare, and most have throttling hidden in the fine print.
- Holafly: unlimited from $19, throttles after heavy use
- Maya Mobile: unlimited Europe plans near $25 per week
- BNESIM: flexible unlimited daily passes
- Expect speeds to drop after 2 to 5 GB per day
For most people a large fixed plan with 20 to 50 GB costs less and performs the same in practice.
Always confirm the throttle threshold in the fine print, since it varies from 2 GB to 50 GB per day.
