ByteSIM vs Airalo feature comparison
Here’s a more detailed breakdown of the features offered by ByteSIM and Airalo and how they measure up side-by-side.
App experience and setup
Both ByteSIM and Airalo apps provide a similar eSIM activation process. You can purchase an eSIM, receive and scan a QR code, then follow on-screen instructions to install your eSIM.
Pricing and data plans
ByteSIM has 500 MB daily plans that cost $2.90 for three days. On the other hand, Airalo also has free three-day 500 MB data plans for some destinations.
ByteSIM also offers a seven-day, 1 GB data package for $4.50, the same as Airalo’s 1 GB options that last 7 days.
It’s also worth mentioning that Airalo’s validity is preset and tied to the data option. They offer destination data packages for 1 GB valid for 7 days, 2 GB for 15 days, 3 GB for 30 days, 5 GB for 30 days, 10 GB for 30 days, 20 GB for 30 days, and unlimited data for 10 days.
ByteSIM, however, provides additional data options with 30 and 50 GB and lets users choose between 1, 3, 5, 7, 10, 15, 20, and 30 days of data.

However, ByteSIM allows users to choose their networks.

- SoftBank & KDDI: dual Network, and stronger coverage
