  • My bedroom is in the basement of the house, I had absolutely no reception. I could not send or receive text messages, but after I got Cel-Fi, I am wearing my thumbs out.

  • With my Nokia 900 and Nexus I used to have to charge them every day, now that I have Cel-Fi, I have definitely seen an improvement on the battery life of my handsets.

    Brian L - Toronto, Canada
  • It took me a while to convince myself to pay for Cel-Fi, but I realized if I amortize the expense over two years it is less than a dollar a day. It is really worth a dollar a day!

    Edward G- Huntsville, Alabama
  • Before Cel-Fi, I used to get tons of drop calls, but after installing Cel-Fi I don’t have any. I now have great coverage around my big house.

  • “With Cel-Fi installed, I got better faster downloads on my smart phone than I did from my fixed line DSL service!”

    Doug H. – Shelbyville Tennessee
  • I was planning to change operators, any not looking forward to the hassle or the expense, but now with Cel-Fi I have great service and no need to change/or break my contract.

  • I was looking at another booster device but I realized that one required an antenna mount and orientation it was complicated; the other option had a cable between devices.

    Pelagia N – Ashton, Maryland
  • I used to leave my phone on the upstairs window sill, and then every time it rang I had to run upstairs to answer it, what’s the point of having a mobile phone? Now with Cel-Fi my phone goes where I go.
