Recommended Actions

Customers using Sierra’s AirLink Management Service (ALMS), AirLink Mobility Manager (AMM) or AirLink Manager (AM) are encouraged to upgrade to 4.15.3 remotely/over-the-air. If you are not currently using ALMS, this is an opportunity to begin using ALMS to realize the benefits of managing your AirLink routers remotely. ALMS greatly simplifies managing AirLink routers, can save the cost of a truck-roll, and allows AirLink routers to remain up to date with the latest firmware and security updates.
