How to choose a new life mobile line and rate plan? --Keitai Watch

NTT DoCoMo is developing price plans such as "5G Gigaho Premier" and "5G Gigalight" that support 5G, "Gigaho Premier" and "Gigalight" that support 4G, and "ahamo" that is based on online.

First, in the large-capacity plan, the amount of data communication is set to unlimited for "5G Gigaho Premier" and up to 60GB for "Gigaho Premier". Tethering for connecting PCs and game consoles can also be used according to the data communication volume of each plan, and if the monthly data communication volume is 3GB or less, 1650 yen will be discounted from the monthly usage fee. On the other hand, the tiered plans "5G Gigalite" and "Gigalite" are tiered plans in which the amount of data communication changes in four stages of 1/3/5 / 7GB.

As for the voice option, both plans are common, and the "Unlimited Calling Option" that allows you to make unlimited domestic calls for 1870 yen per month and the "5-minute Call Free Option" that allows you to make free calls within 5 minutes for 770 yen per month are offered. .. Generally, it is said that the demand for private voice calls is declining, but since it is often needed for work etc., if voice calls are frequently used, we considered applying for an option. ..

When making a new contract with any mobile phone company, you will have to choose one of the rate plans based on the amount of data communication you want to use. Users who have been using it before going on to school or getting a job also change the rate plan as needed, but when users who have already contracted with NTT DoCoMo change the rate plan, it is important to note that "Basic Share" There may be share pack-type rate plans such as "Pack Ultra Share Pack".

New acceptance of share pack-type rate plans has already ended on May 31, 2019, but since the rate plans can continue to be used, many users are still subscribed to these plans. For example, if you have formed a share group with your family and become independent financially as you go on to school or get a job, and you sign a contract for the new rate plan mentioned above, you will need to take steps to withdraw from the share group. Generally, it is assumed that the guardian is the main line of the share pack and the independent user is the child line, but when the independent user is the main line, it is necessary to switch the main line to another contractor of the share group. By the way, independence from the share group and switching of the main line can also be done with my docomo.

Another thing to note about share pack plans is network support. The share pack rate plan supports 4G LTE (Xi), so even if you insert a SIM card into a 5G compatible terminal, you can only connect to the 4G LTE network. If you want to use the 5G network, you need to be independent from the share group and subscribe to 5G compatible rate plans such as "5G Gigaho His Premier" and "5G Giga Light". By the way, NTT DoCoMo states that "a contract with a 5G compatible rate plan is required to use a 5G compatible terminal", and a contract with a 4G LTE compatible plan such as a share pack system rate plan, "Gigaho Premier" and "Gigalight" Operation is not guaranteed even if the SIM card is inserted into a 5G compatible terminal. Actually, even if you insert a SIM card with a 4G LTE contract into a 5G compatible terminal, it will not connect to the 5G network, but it has been reported that it works, but it should be understood that it is not guaranteed.

Also, if you have a contract for a 4G LTE compatible Giga plan instead of a share pack type rate plan, the difference between "5G Gigaho Premier" and "Gigaho Premier" is 100 yen, and "5G Giga Light" and "Giga Light" are Since it is the same amount, it would be wise to switch the rate plan to 5G compatible when you buy a new 5G compatible terminal.
