Drops calls constantly--even when it claims to have an "excellent" WiFi signal--& it echoes so bad that people on the other end can barely understand you. It worked better BEFORE I made the mistake of paying for it 🙄 Since paying for this app, EVERY call is dropped and I'm not sure it's worth $10/month to reserve the#--even though, for mw, it's the only number I can afford. Better to just rely on email (at least that goes through every time).
