This article covers 150MBPS 4G LTE モバイル WI-FI.

Overview

The MERCUSYS MT110 is a compact 4G LTE mobile Wi-Fi router designed for on-the-go internet access. It supports download speeds up to 150Mbps over 802.11n Wi-Fi and can connect up to 10 devices simultaneously. With quad-band frequency support, it ensures stable connectivity across major Japanese carriers. Its small form factor and built-in battery make it an ideal companion for travelers, remote workers, and anyone needing a reliable mobile hotspot.

Connectivity & Compatibility

The MT110 accepts a standard Nano SIM card and works with major 4G LTE networks in Japan (bands B1/B3/B5/B8, etc.). It creates a 2.4GHz 802.11n Wi-Fi network (up to 150Mbps) that any Wi-Fi-enabled device can join — smartphones, laptops, tablets, and gaming handhelds. There is no Ethernet port; the router is purely wireless. Power is supplied via a built-in rechargeable battery, charged through the included USB cable. The device supports up to 10 concurrent connections, making it suitable for small groups or multiple personal devices.

Product Info

The MERCUSYS MT110 sits at the entry level of mobile routers, offering essential 4G LTE hotspot functionality at an affordable price. It was released in early 2024 and typically retails around ¥11,000 on Japan. The package includes the router, a USB charging cable, and a quick-start guide. A 3-year warranty against manufacturing defects provides peace of mind. Purchase options include major online retailers like and electronics stores.

Best Use Cases

Frequent travelers and business commuters: If you often stay in hotels or move between locations, the MT110 lets you use your own SIM for a consistent connection without relying on public Wi-Fi. Setup is straightforward — just insert the SIM and power on. Remote workers and digital nomads: For those who work from cafes, co-working spaces, or temporary offices, this router provides a private, secure network. The 10-device limit easily covers a laptop, phone, and tablet simultaneously. * Short-term overseas visitors: By inserting a local prepaid SIM, the MT110 can serve as a travel hotspot. However, since it is optimized for Japanese bands, check compatibility with your destination's LTE frequencies before relying on it abroad. Users who need 5G speeds, very high data throughput, or wired Ethernet connections should consider higher-tier models.
