SIM Reactivation​ to regain lost prepaid users

​​​​​​​​​​​​​​​​​​​​​​ real-time-sim-reacquisition 

Real-time SIM reactivation detects and reactivates inactive users connecting to the mobile network, allowing operators to reacquire subscr​​​​​​ibers at a reduced cost and turn them back into valuable users. Returning users can conveniently reuse their expired SIM card anytime, anywhere, select their phone number and new personalized services. Operators can implement efficient customer win-back strategies by engaging with dormant SIM users to efficiently fight mobile prepaid churn.

How to fight the multi-SIM users and prepaid churn phenomenons

Prepaid markets users juggle with SIM cards. These cost-conscious users accumulate SIM cards to take advantage of the best voice and data offers, even owning multiple SIM cards from a same operator (the so-called returning users). Their unused SIM cards quickly become dormant and wasted. This multi-SIM user phenomenon increases churn and the SIM card volumes operators need to distribute, as, in many prepaid markets, most SIM cards are for returning users. In addition, the development of affordable multi-SIM devices has encouraged the multi-SIM user phenomenon, particularly in Africa and Asia.

To face this situation, operators need to provision more SIM cards and network resources, sometimes causing phone number (MSISDN) shortages. Some operators shorten the decommissioning delay to quickly free phone numbers for new users. But doing so, they lose customer information, damaging their ability to later regain churned users. Others try to regain users with expensive marketing campaigns. Finally, rejoining users need to perform the full SIM enrolment process again, causing queues, customer dissatisfaction and overloading resellers.
