<div class="">Providers like Republic Wifi work well simply because
the majority of the time most people are around good
wifi signals, but they still need to fill the holes of
coverage - which basically starts the moment you walk
out of the front door. I have multiple friends that use
Republic and couldn't be happier - they generally say
that the quality isn't quite as good as standard mobile,
but for the price they are happy. (FreedomPop is a
different story, and not a company I'd recommend going
near)<br class="">

<div class="">However as far as "VOIP" for mobile call, that's
happening. In the US, Verizon has been doing
Voice-over-LTE (VoLTE) for some time, and others will
likely follow. For Verizon this is a big win as it
allows devices on their CDMA network to handle "voice"
and data simultaneously (as it's all data) - something
they haven't been able to do before now. The LTE spec
fully supports voice-over-data, and it's expected all
carriers will move to it eventually.</div>

This got me thinking, if you took money out
of the equation and politics (sic). Would
it be better for use to have a completely
wifi wireless network, get rid of the mix of
technology and just have devices that do
some sort of VOIP. I am presuming running
an IP network is better than a GSM/3g/4g.<br class="">
<br class="">
How much better would that be ?<br class="">
