Dear Customer,

To accompany the growth of its SmartSIM and EasySIM connectivity services, Sierra Wireless is upgrading its infrastructure to carry us into 2022. This operation has already started for some early customers who have been separately informed and which fleet is now successfully migrated. The generalization of the migration operation will start on November 26th, 2019 to be progressively applied to the fleet of all concerned customers up into Q1 2020.

Which connectivity services are concerned?

Services concerned are SmartSIM (Advanced, or Lite) and EasySIM (Global, EU1, EU2, US) data via public APNs as well as private APNs, SMS, Voice, and USSD. Other Sierra Wireless connectivity services such as ClassicSIM and MainGate will remain unaffected, therefore those customers can ignore this notification.

How my connectivity services will be impacted?

During this migration period, each customer's SIM may experience one momentary loss of connectivity for a few seconds and only once. The connectivity will be automatically reestablished with no change of parameters once the migration operations are complete for the SIM.

Will it impact my interconnection with the AirVantage platform?

The AirVantage user interface and API will remain accessible during the migration period however, their management operation response time may get longer or even time out for few minutes if applied to a SIM at the exact moment it undergoes the migration operations. Extending the time waiting for AirVantage response or repeating the management operation will eventually return successfully.

What does the operation look like?

The migration procedure has been prepared and validated before applying it to all our customer's fleets. However, should an unforeseen issue be encountered, a rollback procedure will move the SIM back to the current infrastructure and keep them operating as before the migration operation.

How my existing commercial contract with Sierra Wireless will evolve?

All the Terms and Conditions in your contract remain unchanged after this operation.

What does Sierra Wireless recommend?

You do not need to consider changing your application logic during this migration period.
