"Mobile Router" SIM Free Model Recommended 4 Selections convenient to combine with cheap SIM [September 2021]

　"Mobile router (mobile Wi-Fi router)" that allows you to connect PCs, tablets, and portable game consoles stably online even without fixed communication lines.

　In addition to the products sold by major carriers and sub brands, there are SIM lock -free models that are purchased by terminal alone and combined with cheap SIMs.

　It costs money when purchasing a terminal, but by choosing a cheap SIM that suits your usage, you can reduce the monthly communication cost.

　The first thing I want to check when choosing a mobile router is the maximum communication speed.This maximum speed is a theoretical value, and it does not actually reach its speed.However, if this theoretical value is low, the actual internet speed will be slow, so the first thing you want to care about when choosing a product.

　There are two main points that affect the communication speed.One is a mechanism that connects the base station and the mobile router, which corresponds to mobile communication standards such as "5G" and "4G (LTE)".

　The second is a mechanism that connects a mobile router with a personal computer or tablet.Most are Wi-Fi (wireless LAN), and if the Wi-Fi version is old or the connection status is poor, the speed will decrease.In addition, wired connections may be made with a USB cable.

　5G -compatible products have already appeared in mobile routers developed by carriers, but most of the SIM -free mobile routers are still 4G.

　In addition, SIM -free mobile routers combine the terminal and SIM (line), so if the corresponding 4G frequency (band) does not match the terminal and SIM, the maximum specifications are demonstrated in the area and communication speed.You will not be able to do it.

　Most SIM -free mobile routers sold in Japan are multi -mobile routers that can be used with SIM cards for any carrier.However, be aware that some products are only compatible with NTT DOCOMO, such as NTT DOCOMO.

　SIM -free mobile router selection is the size of the SIM card that becomes a surprising pitfall.

　The main smartphone is the mainstream model that uses "nanosim card".On the other hand, there are many models of the Microsim Card slot, which is one larger than the mobile router.

　Changing the size of the SIM card is basically required to reissue, and it takes time and time.If you use a cheap SIM that has already been contracted, check out which mobile router you want to buy is nanosim or Microsim.

　If you sign a cheap SIM according to the mobile router, you need to be careful not to make a mistake in the size of the SIM card when applying.Some businesses use multi -size SIMs that can be used separately to either nanosim or Microsim.
