Doesn't the Nexus 5 come unlocked? But I'm guessing you want some on contract?

Republic Wireless is contract free. They actually implement a data/voice collaboration between wifi and cellular. It's a pretty awesome concept and even will switch over without issue in the middle of a call.

This allows them to make their most expensive unlimited 4g data and talk plan only $40 a month. Also you can change your plan multiple times a month (since it's contract free). Say you;re going out the country and only want calls on wifi, switch to the $5 a month wifi plan in a minute. Need cellular calling but no data for their $10 a month plan for a few days? Again only takes a a minute to switch

But because of this technology, you need phones that they have implemented the software possible to do so.

They are picking up steam so hopefully the are able to do it with more phones at a faster pace. The word about the company can't get out quick enough. It's no BS either. Check the reviews. Everyone is raving about them.

And no I don't work for them. :P I am Just a customer that realizes how awesome they are.

OH right I remember them. I don't live in the US so sometimes I forget about these guys :P
