So drop $5 in the Play Store for one of the Voice-over-IP apps, and use your Google Voice number. Then you can just get a data-only plan and call it a love story - no voice plan required at all. WiFi at home, 3G "oot and aboot".
I was looking into this. Google Voice looks cool but if I want to use my existing cell number I have to pay the $20 processing fee and termination fee to T-Mobile (already on another 2 year contract, 700 minutes which the 4 lines on my plan never reach because we all text like crazy or use unlimited nights/weekends and myFavs, unlimited data, etc). If there's a way to use my existing number without that headache please, anyone, let me know, If I use a specific Google Voice number I'd have to change my number with my job (legal requirement) so if I go ahead with getting a Nexus 4 the least headache-inducing options I feel I have so far are;
1. Easiest?forgo WiFi calling and expect to head to a window to carry on a call.
2. Sign up for Google Voice with a
Google Number and rely on that and an app like
GrooVe IP for WiFi calling.
3. Purchase/install a cell repeater in my apartment (of course there's the outside part, too).
Side note; Check out this AndroidCentral
video about enabling Developer Options in JellyBean 4.2 on the Nexus 4... one of the options is
Force 4X MSAA (in OpenGL ES 2.0 apps)... old news?
