I have already used my cell phone number for 2 google voice accounts. I believe the maximum is 2. Now I need another google voice number. What do I do? years ago I could buy a t mobile sim card from ebay for $5 and it already had a number attached to it, and like 3 minutes of talk time attached to it. I would insert the sim card in my unlocked phone, verify google voice, and then throw it out. But I cant find those any more. how to verify google voice?
