SMS Queue – Maximum Number of Messages and Maximum Age

The Globalstar SMS Text Message queue is limited to a maximum quantity of 30 messages per subscription, and a maximum message age of 30 days.

Queue Size Algorithm:  When the 31st message enters the queue, the oldest message will be deleted, in order to maintain the queue size at or less than 30 messages.

Message Age Algorithm:  SMS messages older than 30 days will be deleted regardless of how many messages are in the queue for that Globalstar subscription.
