TeleCom Square

TeleCom Square operates out of Japan and brings an international perspective to eSIM distribution. Mexico coverage is available, though the service requires registration to purchase plans, and users access it primarily through the dedicated eSIM Square mobile app rather than a traditional website checkout.

It's a good fit for travelers already familiar with Japanese telecom ecosystems or those seeking an alternative to Western-based providers. The app-first approach works well for people comfortable managing mobile services through their phone, though it adds a setup step compared to simpler QR-only competitors.
