A mobile router is a device that blows Wi-Fi using a carrier line, but most are of the type provided by carriers or of a type that uses a SIM card. On the other hand, “WiFi at any time” does not contract with any carrier, but it has a mysterious structure that all three carriers can use the line.
The secret is a technology called Cloud SIM. By automatically applying the SIM card information on the server, it will lead to the most advantageous carrier at the site of use. However, since there is no display on the main body, I don't know where my carrier is. Probably connected to the au line, but there is no limit of 10GB in 3 days or 30GB per month.
In terms of speed, this is about 20Mbps at night in Miyazaki city. Up until now, the contract was made in June, and it has been used as the main line of the room rather than mobile.
In addition, “anytime WiFi” is labeled “unlimited unlimited use”.QA page of the siteThen, about speed limit,Restrictions may apply only for unauthorized use and large-capacity communication at the network occupation level. (Omitted) For example, there is no limit on the use of “playing games for a long time / watching videos”.".
Previously, my smartphone had contracted a plan of 20GB per month, but switched to a metered plan. If "Mobile data communication" is turned off in the settings and only WiFi is used, the lowest usage fee will be charged. The minimum step is 1GB, but there are still more than 910MB even though this month will be over 20 days.
▲ SIM can be inserted by opening the lid.
In terms of price, it is cheaper to say that carrier tethering is cheaper, but now that it is a pay-as-you-go plan, it is appreciated that it can be used with a fixed daily charge. There is also a function to prevent overuse of data, so I would like to use these settings well.
On the other hand, the number of simultaneous connections is limited to five, so if you connect a smart speaker or anything else in addition to a smartphone or PC, it will be buried immediately. This area is for mobile use only, so there is no way to do it.
Also, since the main unit is tied for two years, if it is necessary to replace the main unit due to battery deterioration or submergence during that time, it is hard to pay 18,000 yen (excluding tax) to purchase a new router . However, if you use it carefully, it will likely last for about 2 years, and it will be 5G in 2021, so it can be said that the timing is just right.
Personally, there is no need to say hiyi with monthly communication capacity, and the stress is greatly reduced. The two MVNOs that had been secured as backup lines were also canceled and the contracts were cleared. It is also recommended in the sense of proceeding with the disconnection of useless lines.
