Dell Voice is a free VoIP service that uses 3G data or WiFi.
You simply install Dell Voice App on Android, and get a free phone local phone number.
You then set your Wind Phone to forward conditionally "when unreachable" to your Dell Voice number, and then you'll get your call routed through wifi.
I tested it out on my phone, and it works like a charm!
You can also call out for free from the Dell Voice app, but outgoing caller ID is your Dell Voice number.
The best thing about it is that it's free and solves a problem I've been having since I've joined Wind...
Hope it helps some of you with coverage gaps, where you do have wifi...
Looking forward to Wind HSPA coverage improvements within the home zones. I can't wait for 5-bars everywhere! And at least some coverage in all major buildings... Especially Rideau Centre and St. Laurent Centre in Ottawa.
