How do you evaluate reliability in travel eSIM providers?

There are dozens of global eSIM apps promising coverage in 150–200+ countries, but in practice the experience varies a lot depending on partner networks and routing.

For those who travel frequently:

• Do you prioritize unlimited data or price per GB?

• Do you check which local operators are used?

• How important is multi-network support vs single-carrier profiles?

• Have you experienced speed throttling with “unlimited” plans?

Curious how people here assess real-world reliability beyond marketing claims.
