What’s an IMSI?
The International Mobile Subscriber Identity uniquely identifies every mobile subscription. It is stored on a SIM and contains essential information such as the country in which the subscriber is registered, and the mobile network to which they belong.
It also identifies the user via your number, so it’s essential to protect the IMSI to prevent fraud. Most subscribers have a single IMSI – but not those of Trustmobile.
What’s an MSISDN?
The Mobile Subscriber ISDN Number is, basically, your phone number. It’s the number used to reach your device and to connect you to different services. It is used for both messaging and when you sign up for an application, such as iMessage, Signal or WhatsApp.
While you might only wish to give your mobile number to a limited number of people, it’s still used by the network – so can be vulnerable to bad actors.
So, how do we protect you? We diffuse your signature, so it’s harder to trace
The IMSI is your on-network signature, so by controlling this and never exposing an IMSI that matches your MSISDN, we can separate your key identifiers – and reduce the risk of exposure. We can also change the IMSI, using our growing range of options.
This separation ensures the identity needed for enabling network connectivity is never associated with that used for inter-personal interaction and communication.
Benefit from our virtual MSISDN, controlling how you expose your contacts
We give you virtual MSISDNs, so you can have different personal identifiers, which you can share in the way that suits your business. We have a wide range of MSISDNs available, giving you the opportunity to select numbers from different countries.
By changing your MSISDN when it suits, you can control your identity with different applications and reduce the risk of exposure, protecting your identity.
Trustmobile offers Multi-IMSI control, giving you different network profiles
Trustmobile supports multiple IMSIs, allowing the IMSI to be changed – switching the network profile according to rules and policies that protect the profile on the network. Users can also switch profile on their devices, providing ultimate levels of control.
Our advanced monitoring services will automatically take action should we need to change your key identifiers, swiftly eliminating detected threats.
