    Hello

    I am a new customer of modem router EZR24-05G i like to understand some possible feature upgrade for this product if is capable or the hardware not allow

    Here my tree request

    1) Dual sim function will be activated as a backup
    2) What kind of mobile connection is connected (5G or 4G LTE or 4G LTE advance)
    3) Traffic statistic, Limit threshold, SMS alert

    • Outdoor Router says:

      Thank you for your great and valuable advice. We appreciate your interest in new features to improve this product.

      1) Dual SIM functionality is hardware-dependent. Unfortunately, the EZR24-05G model only has a single SIM slot for the 5G module. EZR34T series outdoor 5G routers support dual SIM slots and auto backup.
      2) The 5G router connects to 3G/4G/5G according to the signal quality. When connected to the 5G-NR network, the front page shows “5G-NR” on access tech.
      3) Traffic statistics, thresholds, and SMS alerts are great feature ideas. Our development team is always working on enhancements like these.

      Thank you again for your feedback. We aim to provide the best experience for our customers.
