Google Fi Or Republic Wireless: Which Cheap Cellular Service is BestGoogle Fi or Republic Wireless? If you are tired of high monthly cell phone bills there is relief available. You might have heard of Republic Wireless but Google’s Project Fi is new and not really promoted by Google yet. So which provider should you choose, Google Fi or Republic Wireless?First some background. Republic Wireless has been in business since 2013 with a mission of helping users lower their cellphone bills by using WiFi as much as possible. They use phones modified to route calls and data over WiFi in preference to your cell connection.As the graphic shows Republic Wireless can cost as little as $10 per month if you use no cell data. Many customers will use only 0.5 GB of cellular data and wind up paying less than $20 per month. That is a good deal. So what is the downside to jumping on the Republic Wireless bandwagon?Well, the Republic Wireless phone choice is limited to Morotola Moto E, Moto G and Moto X phones with a maximum of 16 GB memory. You do have the option to special order a Moto X with 32 GB storage for $350 direct from Motorola if you are prepared to wait for the phone to ship. Most users would order the stock Moto X with 16 GB memory for $250.While $250 may seem like a good deal for a new phone realize that 16 GB of memory is now considered bare minimum for an Android phone. You will soon find you have maxed out memory and have to start removing apps you do not consider essential. Most users really should be considering 32 GB memory instead if finances permit. Android power users won’t buy a new phone without 64 GB memory minimum.Republic Wireless phones have custom firmware to handle the hand off from WiFi to cellular so a phone you buy from them cannot be taken to a different carrier just by changing the SIM card. They do offer a 30 day money back guarantee if you do not like the phone you buy or the service.Enter Google Project FiGoogle has been quietly rolling out their Project Fi to new users at the Project Fi website.
