IMSI Change

Prodo Telecom is currently working on a project to change the IMSI (SIM) range of a mobile Operator’s entire subscriber base. In the past Prodo has had extensive experience with updating IMSIs for specific projects- these included dynamic IMSI allocation for new subscribers, updating different IMSI subscriber segments for MNOs or updating the Mobile Country Code (MCC). Nevertheless, this is the first time that we have been asked to update the entire subscriber base.

The IMSI update petition comes as a consequence of a merger between two Mobile Carriers. With the change of IMSI, the Operator is hoping to streamline their organisation, reduce internal roaming costs and issues as well as better manage their SIM cards.
