Don't download this app, it's a horrible unreliable Google service. My linked number suddenly became unlinked/linked at the same time and I missed important business calls today because of this. No online support beyond trial and error. Google voice is garbage and should be removed from the play store until Google can ensure your voice number will always be available for use and linked numbers won't unlink themselves when Google makes changes to the voice legacy features. Trash-tier app; BEWARE!
