Explain the cheap SIM IIJmio "Gigabit Plan" [April 2021] with five main points: 858 yen per month at 2 GB.

　Cheap SIM brand IIJmio launched a "gigabit plan" of a new charging plan in April. 20 GB 2068 yen (including tax, the same below) is a reasonable plan. With regard to this gigabit plan, let's examine it with five key points.

IIJmio's "gigabit plan" is

　The "Gigabit Plan" is a new plan offered by MVNO's IIJmio since April 1st.

　NTT DoCoMo as a similar name, the "Gigaho Premia" and other programs collectively referred to as "DoCoMo's Giga plan", please note that this is different.

　Then, the service of the gigabit plan is divided into "voice SIM", "SIM with SMS function", "data communication dedicated SIM" and "eSIM", and the fee is set to five levels according to the data capacity.

　There are two kinds of communication lines: DoCoMo line and au line, and only DoCoMo line network is used for SIM and eSIM for data communication. The 5G service will be available from June and can be used at no extra cost. There are also charges for other cheap SIM cards, so it can be said that it is a unique advantage of IIJmio.

　In addition, SIM and eSIM with SMS capabilities on DoCoMo lines do not support 5G.

The basic cost of IIJmio's "Gigabit Plan" is 858 yen to 2068 yen.

　The basic monthly cost of the gigabit plan is the voice SIM used on smartphones. The monthly plan for 2 GB is 858 yen, 4 GB is 1078 yen, 8 GB is 1518 yen, 15 GB is 1848 yen, and 20 GB is 2068 yen.

　The online dedicated plan of large operators costs 2,728,2970 yen per month for 20 GB, which is lower than the plan of the same capacity. In addition, the accompanying voice service for 2 GB or 4 GB can be maintained at about 1000 yen. In addition, we have also prepared a contract with IIJ's optical line service "IIJmio Optical" to sign a "mio discount" of 600yen per month.

　By the way, the characteristic of eSIM is that it is cheaper than SIM for ordinary data communication. For example, in the case of 2 GB, data communications dedicated SIM costs 748 yen per month, while eSIM costs 440 yen. It is recommended to run on devices that support eSIM, such as iPad.

What is the cost of IIJmio's "gigabit plan" voice calls?

　The voice rate is 22 yen / 30 seconds. In addition, if you use the user-oriented phone app "Miofuten dialing", you can use the half price of 11 yen / 30 seconds.

　For people with high call frequency, a call quota option is provided for dialing. "call quota of 10 minutes" (913 yen per month) and "call quota of 3 minutes" (with 660 yen) are options for smooth domestic calls at their respective times.

　In addition, if your phone number is the same service ID (MioID), such as signing a group agreement with your family, the phone bill will be cheaper.

Can the data capacity of IIJmio's "Gigabit Plan" be carried forward?

　The gigabit plan can carry forward the remaining data capacity (packets) to next month. You can also sign up to 10 lines under the same name and share data capacity between these lines (available after 6 months).

　After using up the data capacity, the communication speed will be limited to 300kbps, but you can also deliberately "turn off" high-speed communication to save data capacity.

　This is because high-speed communication can be turned on / off in user-specific applications, and the data capacity will not be reduced when closed. However, exceeding the 366MB within 3 days may be subject to communication restrictions.

The main end point of IIJmio sales

　IIJmio offers a wide range of devices, including smartphones, tablets and mobile Wi-Fi routers.

　Smartphones are dominated by mid-range models of 20, 000 to 40, 000 yen, but they are also characterized by some high-end models such as the HUAWEI P40 Pro 5G, which cost more than 100000 yen.

　The IPhone series deals in second-hand unused goods and beauty products. Although the latest "iPhone12", "iPhone12mini" and so on are also prepared, the limited quantity is still in the state of insufficient inventory. If the time is right, maybe you can buy it. Similarly, iPad is on sale.

　In addition, tablets that support eSIM, such as the Asustek TransBook Mini T103HAF, are also available. Please confirm the details on the official website.
