The Google Voice and Sprint integration which was announced in March this year, went live on May 3rd.
Google said there're two ways to bring Google Voice to your Sprint mobile phone. In both the cases below, Google Voice replaces Sprint voicemail and international calls made from the Sprint phone will be connected by Google Voice.
- Keep your Sprint number: Your Sprint number becomes your Google Voice number so that when people call your Sprint mobile number, it rings all the phones you want.
- Replace your Sprint number with your Google Voice number: All calls made and texts sent from your Sprint phone will display your Google Voice number.
"Until now, if you changed your Google Voice number, ported your number to Google Voice, or opted in for the Sprint Option 1 integration (above), your previous GV number remained on your account for 90 days before it was returned to Google."
Google is now offering users to make your secondary Google Voice number permanent on their account. "This means that calls made and text messages sent to your previous number will still reach you, however, your new primary Google Voice number will display on caller ID when you make calls or send text messages," explained Google.
To keep a previous number on your account, log in to Google Voice, visit the Settings tab, and click "make permanent" next to the number that you want to hang on to. There's a one-time $20 administration charge to make it permanent, and the process is instantaneous.
