Hello I am hoping to get app recommendations here! Virgin Mobile 300 minutes plan, strong 3G but no wifi. I'd like to receive phone calls from one (wordy) contact without using voice minutes. The Google voice number is forwarded to Google chat only. Groove IP drains battery too fast if constantly on, I have Tasker but toggling is probably too slow for taking calls? Not sure if I am missing the obvious, is there an app out there that uses minimum resources running in the background and can answer GV calls? Thank you very much!
