Upgrade - Knowledgebase / App Overview - Signal Spy


Authors list

If you are a free user, you can upgrade to Pro for $2. This adds not only the extra history features we mentioned before, but it also removes ads, enables root and rootless copy-free dialer codes, provides access to the Preferred Network feature, allows you to change the app's theme,  and more features as our app grows. You can also donate beyond $2 if you are so inclined and become a Backer! We appreciate it!
