Device Operating System Policies
It is important to keep mobile devices running up-to-date operating systems in order to stay current with the latest security enhancements. Spok reviews its OS support policies regularly to ensure the Spok Mobile solution continues to provide secure messaging for our customers. Spok reserves the right to drop support for an operating system at any time if major security issues are found.
