Roaming Management

Scroll Down


A large share of an MNOs (Mobile Network Operator) revenue is contributed by roaming services. In the absence of right roaming agreements and effective solutions, the subscribers could end up paying very high roaming charges which leads them to get local subscriptions while traveling. With the right network partners and calculated strategies in place, MNOs are able to optimize their services while keeping loyalty from roaming customers and thereby increasing revenue.

Roaming management solutions for MNOs offer a streamlined process for global connectivity, easy accessibility, user-friendly settings and effective traffic steering. A range of roaming solutions is available via SIM Card applications for MNO implementations.


The solution can be implemented in a number of ways as below


  • Preferred Partners - A mobile operator maintains a list of preferred international roaming partners in the sim card. This ensures that the subscriber registers with the preferred partner network while roaming. The partner list can be updated on a regular basis by the 'Home' MNO via OTA* campaigns. The subscriber benefits from good roaming rates.

  • Multi-IMSI - There can be multiple IMSIs on a single (U)SIM card for the 'Home' MNO and its roaming partners. This ensures that the subscriber while roaming, is always registered as a local subscription. The roaming subscriber saves on high roaming call charges and stays with the subscription of the 'Home' MNO. This also encourages higher usage from the subscriber.

  • Call Back Service - In this method, the subscriber initiates a call back session from a sim card application. The 'Home' MNO then dials the phone number and sets up a bridge for the calling subscriber. The 'Home' MNO should support USSD callback for this service. This way the calling subscriber saves on high rates for making international calls while roaming.
