For many years prior to retiring, selling my house and traveling/living full-time in my motorhome beginning in March 2017, I had a FAX machine in my home. Although FAX is an old technology and my machine did not get heavy use, it was an especially convenient way to quickly and securely communicate with those who were unwilling or unable to use email. On vacating my house I lost that convenience and particularly missed it when, during my travels, I had to use an office supply store or mailing/shipping facility to send/receive FAX messages. Even wireless printers and FAX machines need a conventional phone line to send and receive FAX transmissions which, until recently, was unavailable to me as a full-time RV traveler. There are, of course, Web-based services that will convert email messages into FAX messages and vice versa, but their monthly charges usually range from about $8 to $17. Free FAX services severely restrict the number of pages and quantity of FAX messages that can be sent or received. Here is the way I was able to recently obtain a conventional phone line that operates wirelessly. An OBi200 1-Port VoIP Phone Adapter with Google Voice and Fax Support for Home and SOHO Phone Service can be connected to an Internet router with a standard CAT-5 cable. After it has been configured with Google Voice, unlimited phone and FAX calls can be made via the OBi200 using VoIP (Voice over Internet Protocol) anywhere in North America without any monthly or calling fees. Recently I was introduced to the Obihai Technology OBIWIFI5G 2.4/5GHz Wireless 802.11AC Adapter for the OBi200 which allows me to use my cellular hotspot for the VoIP Internet connection. Like most RV owners, I don’t have an Internet router in my coach. Those who do will not need the wireless adapter. Amazon, Newegg and other on-line sellers sell the OBi200 for about $50 and the OBIWIFI5G adapter for about $25, making the total investment for having a conventional phone line in my coach with unlimited calling and FAXing for less than a year’s cost of the cheapest Internet FAX service. Here is a word of caution; VoIP does of course consume data. My data plan with Verizon is unlimited but if yours has limits you’ll need to take VoIP data consumption into account when considering costs. My campground’s office kindly allowed me to use one of their hard-wired Internet connections to configure my OBi200 and wireless adapter, but once that was done their connection was no longer needed. For my needs I used the FAX tool already available in my Windows computer and a modem connection to the phone line. If I’m sending a document from paper, I use my portable scanner, which I already owned. Otherwise I can FAX documents that already on my computer as easily as I can print them. Received FAX messages pop up on my screen which I can view, save and/or print as needed. Conventional FAX machines can now be bought for as little as $25 on-line. Since my installation, I’ve been able to FAX documents thousands of miles across North America and locally as reliably as I could with the land-line that I had in my home. Frequent boondockers can run the OBi200 directly on 12-volts DC or with its included 120/240 volt AC adapter.
