Skip the menu: let OsmO call O2 for you
OsmO is an AI phone assistant app. Tell it what you need and it makes the call: it listens to the O2 menu, presses the keys, waits on hold, and rings you the moment a person picks up.
- Navigates phone menus. Listens to every option and presses the right keys for you.
- Waits on hold. You get on with your day; OsmO holds the line.
- Hands you the call. When a person answers, tap to take over, or let OsmO finish and send you a summary.
- Cuts the noise. OsmO also screens spam and robocalls, so the calls that reach you are the ones that matter.
