In 2021, each telecommunications company made a major reduction in usage fees.Many cheap plans available for less than 1,000 yen have appeared due to the reduction.In the past, it was common to use one telecommunications company, but recently, "Dual SIM operation", which simultaneously operates two telecommunications, has begun to gradually spread.
Cheap plans are not only low in usage fees, but often provide some unique services to acquire users.If you combine them well, you can easily get a communication environment that suits you at low cost.
This time, we actually use "OCN Mobile ONE", which allows you to call for "550 yen" monthly, and "LINEMO" SIM, which can use "3GB" high -speed communication at 990 yen per month, and actually dual SIM.I would like to set.
The smartphone is "Xiaomi Redmi 9T", which is equipped with a Micro SD card slot in addition to the two SIM card slots.If you sign a SIM for audio with OCN Mobile ONE, the terminal that can be purchased for "1 yen" is ideal for operating dual SIM.
First, set OCN Mobile ONE and LINEMO SIM in the SIM card slot.
Select "SIM card and mobile network" from "Settings".
You can see that "OCN Mobile ONE" is attached to the slot 1 and the slot 2 is attached to "LINEMO".
In "Default of Call", set a SIM for calling to use when making a phone call.LINEMO is about half price of "22 yen/30 seconds", OCN Mobile ONE is "11 yen/30 seconds", so this time "1 (OCN Mobile One)" is set.
If you select "/" on the right, press the transmission button and the "Select SIM used in this call" screen will be displayed, and you can choose which number to use each time.This is convenient when you use it properly at work and private.The standby can be performed simultaneously with two SIMs (no settings required).
"Data card" indicates a SIM for data communication.OCN Mobile ONE has a slightly higher power consumption when waiting for data communication.If you set it to LINEMO, the effect of reducing the standby power is low.In addition, "2 (LINEMO)" is set because the ultra -high -speed communication of MNO can be used.
Next, select LINEMO SIM and set "APN" from "Access Point Name".
If "LINEMO" is displayed in the list, select LINEMO.
If not found, input from "New APN" as follows (except for the following).
After the input, "Save" from "Others".Make sure that LINEMO has been added to the APN list and select.
OCN Mobile ONE SIM corresponds to the free option called "Music Count Free" (applying after contract).The communication when using the target music service is "No count".It is very important not to use this excellent option, so let's set it so that OCN Mobile ONE side can communicate data.
From OCN Mobile ONE
The setting method is the same as LINEMO.After changing "Data Card" to "1", select OCN Mobile One SIM.Set "APN" from "Access Point Name".
If "OCN Mobile ONE" is displayed in the list, select OCN Mobile ONE.
If not found, enter the required items from "New APN" as follows (remain the default except for the following).
When the input is over, "Save" from "Others".OCN Mobile One will be added to the list, so select it.
Once the APN setting of OCN Mobile ONE is completed, return the data card to "2 (LINEMO)" and "Mobile Data" is turned on "ON".If the communication is not started, please restart.When the antenna switches to "4G", the setting is completed.
Xiaomi's smartphone is easy to switch between data -related SIMs.Slide from the upper right to display the "Control Center", and just select the SIM you want to use from the mobile data.It will be a very nice feature for those who use music distribution services.
At first glance, "Dual SIM operation" seems to be difficult, but once you learn how to use it, you will be free.Use the disadvantages of each SIM to make use of the strengths.It is quite fun to build your own communication environment!
