Compatibility Guide

The included SIM is a docomo-only prepaid SIM (Micro SIM format) pre-installed in the router. It cannot be used with other carriers. Supported LTE bands include Band 1/3/19/21 (docomo). 5G is not supported. The router supports Wi-Fi 802.11b/g/n on 2.4GHz only, with up to 10 simultaneous connections. It can also be powered via USB (5V/1A or higher), so you can use a power bank.

Ideal Use Cases

  • Car camping / road trips — Keep everyone connected on the go with in-car WiFi.
  • Short-term stays / travel — Perfect for domestic travel where you need large data without a long-term contract.
  • Students living alone — One upfront payment covers a full year, no hassle of monthly bills.

Upgrade Considerations

This is a prepaid service; once the 100GB is used, you can recharge additional data via the official website. The Aterm MP02LN has a built-in battery that will degrade over time. Battery replacement is handled through Kaus Media support. If you need faster 5G speeds, consider a 5G-capable router and a separate data plan.
