    The SEA4 SIM has been perfect for our GPS-fleet tracking, set it up and forgot about it for the full year. No hassles, no hidden fees.

    - Logistics Manager, Singapore

    We used the 60 GB/365-day plan for our POS kiosks across Malaysia and Thailand. Data stayed solid, shipping was free, and we didn’t need to worry about contract renewals.

    - Retail Deployment Supervisor

    For our remote sensors in Indonesia the 12 GB/365-day plan hit the sweet spot: reliable 4G, plug & play with APN pre-set, and we only needed minimal setup.
