International Mobile Subscriber Identity or IMSI is a number used to authenticate a SIM on a cellular network. This ID is standardized by the International Telecommunication Union (ITU).
Each IMSI has an allowed network coverage list attached. In other terms, a limited number of Operator Networks can be attached for a specific IMSI. This limit is depending on the number of roaming agreements which have been negotiated and agreed between an operator and their network partners.
A multi-IMSI is a SIM that holds two or more IMSI profiles, which can be switched between to improve device connectivity and up-time.
Each SIM has up to multiple profiles or IMSI’s. Your devices will cycle between connectivity until it finds a profile or one of it’s roaming options that it can connect through.
On top of this, each SIM can have additional profiles. New profiles can be loaded to the SIM over-the-air to further optimise connectivity, device performance, and reduce costs.
If for whatever reason your device cannot connect to its chosen default profile, it will cycle through its connectivity options until it finds an available mobile network. Between these profiles and their roaming options, we will provide you with access to over 700 mobile networks worldwide to achieve near 100% up-time for your IoT devices.
