In this article, we will provide a detailed explanation of "SIM," a term you may have heard of often but may not fully understand, or may be too embarrassed to ask about.
What is a SIM
SIM is an abbreviation for "Subscriber Identity Module".
This is an IC thatis inserted into a device or mounted on a boardand records user identification information, phone number, etc.
Using a SIM card, you can connect to the telecommunications company's network and use the Internet and make calls.
SIM type
There are twomaintypes ofSIM cards:
Macnica Connect SIMis available in both shapes, so please choose the one that best suits your device's specifications.
SIM card
This is a card-type SIMthat is also used in smartphones.
By switching the connector, you can use different carrier networks.
eSIM (chip SIM)
This type of SIM can be directly embedded in a circuit board. It can be soldered directly to the circuit board, making it possible to miniaturize devices.
In addition, because it is mounted on a board, it reduces the risks of physical vibration and theft.
What are MNO and MVNO?
MNO (Mobile Network Operator)and MVNO (Mobile Virtual Network Operator)
Both companies provide telecommunications services, but there are significant differences in how they operate.
MNObegan as a service provided by telecommunications carriers that owned transmission line facilities.
The transmission line equipment mainly consists of a base station (Cell), a core network (EPC), and subscriber information devices (HLR/HSS).
What is MNO?
An MNO is an operator that owns the aforementioned transmission line facilities and is assigned frequency bands directly by the Ministry of Internal Affairs and Communications.
The major MNOs in Japan include NTT Docomo, KDDI, SoftBank Corp., and Rakuten Mobile.
What is MVNO?
MVNOrefers to a company that rents communication facilities from MNO to provide mobile phone services.
A telecommunications carrier that provides mobile communication services using the mobile communication services provided by an MNO or by connecting to an MNO,
The Ministry of Internal Affairs and Communications defines a mobile telecommunications operator as "a person who does not establish or operate a radio station (base station) related to the mobile communications service in question."
The appeal of this service is that it allows us to offer low-cost, highly flexible services by keeping initial investment in equipment to a minimum.
Since the service is provided by renting transmission line equipment owned byMNOs, it is possible to provide services at low cost since there is no need to maintain and manage the equipment.
What are full MVNO and light MVNO?
There are two types of MVNOs: "full MVNOs" and "light MVNOs."
The difference between full MVNO and light MVNO is mainly to what extent the operator has the necessary functions to provide communication services.
It is defined by how much itborrows from MN O.
Full MVNO
Among MVNOs, operators that own their own EPC and HLR/HSSare defined as full MVNOs.
We provide our own SIM cards, operate and manage stable communications, and can activate and change profiles remotely.
This allows us to provide more flexible and flexible services.
Light MVNO
Although the company handles its own service sales and customer management, and relies on the MNO for functions such as authentication and core network, it is able to provide services at low cost without incurring management costs.
