Since the early days of mobile broadband many people have asked us about using their 3G service for Voice Over IP (VOIP) services like Skype, Vonage, or Ooma. VOIP service over a 3G mobile broadband connection is possible, but with some limitations. Using VOIP over 3G requires a very strong signal for good call quality, and without a great connection there can be a noticeable lag time in the conversation due to the inherent latency of 3G technologies. Monthly usage limits have also posed a problem for heavy VOIP use - while some VOIP services don't use much data (the Ooma, for instance), others can quickly chip away at the 5GB monthly allowance most 3G providers impose.


To put CLEAR's service to the test for VOIP, we had one of our team members make two calls with his VOIP phone - one over 4G (he used the CLEAR 4G USB Modem [left] connected to a Cradlepoint MBR1000 router), and another while connected to his uber-fast cable connection. Listen to the call recordings below to hear how each one sounded - there is NO discernible difference in quality or latency between the two calls!
If CLEAR is available in your area, it is a great option for replacing wired connections at home like cable or DSL for all your internet needs - including VOIP! CLEAR 4G plans are affordably priced, starting as low as $30 per month.
