MVNO SIM range - How can an MVNO get SIMs?
To become a successful MVNO, you need to consider various issues about SIM cards and get all the requirements needed for a profitable MVNO business.
Full MVNOs own the Core Network and use the RAN part of an MNO. It is mandatory for them to have a SIM range and own the IMSI codes of subscribers.
Read all about the MVNO SIM card and the things you need to know in order to get your MVNO SIM range.
What is a SIM card?
Subscriber Identification Module (SIM) card is an integrated circuit that connects the user equipment or mobile station to the mobile network. The SIM card stores all the information about the subscriber and the HSS/HLR uses all that information to manage the subscriber’s identity.
SIM cards are memory storage facilities for several fields such as Service Provider Name (SPN) and the ICCID, IMSI and MSISDN. To manage the SIMs you can use either Remote Applet Management (RAM) or Remote File Management (RFM) or even both.
ICCIDIntegrated Circuit Card Identifier is the identifier of the actual SIM card itself because it acts as the identifier for the SIM chip.
IMSIInternational Mobile Subscriber Identity allows SIM cards to be identified by their operator networks by a unique code. Network operators use this code for the authentication and registration of the SIM cards using their MVNO IMSI. The IMSI code has the following format:
✔MCC: The first three digits represent the Mobile Country Code
✔ MNC: The next two or three digits represent the Mobile Network Code
✔ MSIN: This represents the Mobile Subscriber Identification Number filling in the remaining digits. This allows your MNO to match any of your subscriber who inserts a SIM within that range to your HSS/HLR
MSISDNThe phone number of the subscriber.
✔ The MVNO IMSI and the MSISDN are related to ensure security for the user. For example, if a phone is stolen and the user wants to make sure his data is not to be used in any way he can ask the operator to track and relocate the IMSI code if its MSISDN using the HSS database
Full MVNOs require an agreement with a SIM card provider for the functionalities, applets and for the MVNO IMSI range to be integrated into the cards.
This is important because the MVNO business relies mostly on the special prices offered to the subscribers. The MVNO SIM range has to provide the technical requirements to ensure the possibility of those prices as a part of the business model.
SIM cards have developed gradually, along with advances in technology. The development of SIM cards can be broken down into four groups and each of them could work as MVNO SIM range.
Regular SIMIn GSM the SIM card was considered both the hardware and the software. Today this is known as the regular SIM. If the operator or the subscriber requires changes to be made they would need to change the card itself.
uSIMThe universal SIM is a software-only application developed as a part of UMTS. The hardware part is called UICC (Universal integrated circuit card). You can make all the changes you need only on the software application.
iSIMThe IP Multimedia SIM was created to serve the VoLTE technical requirements. It has parameters for authentication and registration to the IMS Core Network. The ISIM application can also work together with a regular SIM or USIM on the same UICC (hardware)
cSIMThe CDMA SIM is an application to support Code-division multiple access phones with an applet called Removable User Identity. By porting the application to the UICC, a card with CSIM can move the subscriber identity from one phone to another by simply inserting the SIM card.
eSIMThe embedded SIM is included on soldered to the motherboard allowing you to make the changes you need on the SIM using OTA technology (over-the-air messages). The SIM card's circuit is connected to the phone, and they communicate with each other. One difference between eSIM and traditional removable SIM is the number of profiles. The eSIM can store different profiles, but the traditional removable SIM cards only store one profile. This technology provides flexibility to operators and is used especially for number portability.
How to get MVNO SIM cards?
1.Full MVNOs can buy them from a SIM providerIn this case, the MVNO has its own HSS/HLR, and everything happens in the home network. Depending on the business model the MVNO aims for, you will have to contact a SIM provider and ask for certain specifications. There are many SIM providers out there, and an MVNO can choose the best SIM cards for its business according to the services he is planning on providing. The SIM providers could manage to configure the card according to your technical requirements.
2.Light MVNO can use the SIM cards from the MNO supplying the networkThe HSS/HLR takes care of the authentication and registration of the subscribers. If an MVNO chooses to take a certain SIM range from the MNO, then the HSS of the visited network knows which range belongs to the MVNO. It will send the home network information to that range. This way, the SPN will be the name of the MVNO.
What kind of technical requests should MVNO SIM have?

» HPLMNwAcT - HPLMN with Access Technology
✔ UST (uSIM Service Table)
✔ CBMI - Cell Broadcast Message identifier selection
Multi-IMSI✔ Support multiple IMSIs and possibly MSISDNs on a single SIM card
OTA SIM provisioning✔ Over-The-Air messages for altering SIM parameters and installing applets
eSIM provisioning✔ Support provisioning eSIM for smartphones or IoT / MTC devices
Types of applets an MVNO could install on a SIM
Multi-IMSI appletIf the MVNO needs multiple IMSI codes on a SIM card
Digital signatureVerifying the authenticity of digital messages or documents
Banking appletFor interrogation of different banking transactions
UICC Carrier privilegesCarriers have full control of the UICC, so this mechanism provides a secure and flexible way to manage apps from the MNO hosted on generic app distribution channels (such as Google Play). This is done while retaining special privileges on devices without needing to sign apps with the per-device platform certificate or preinstall as a system app.
