Google Voice?I currently have three phone numbers that can ring my phone. The only downside is there doesn't seem to be a obvious way to indicate which line is being called.
You don't need to have data to receive GV calls and texts on your mobile - GV will forward these to your mobile number as calls and texts. Texts will come in from a different number than then sender's actual number (the senders number or name from your Google contacts is added to the message body) - you can text back (or call) this number from your mobile to automatically route through GV and have your GV number be displayed to the recipient.To place a call to a number that has not texted you through GV, you either need data or you need to call your GV number and place the call through the voice menu system. Data is required if you wish to text someone who has not yet texted you through GV.
