Review: Did not boost signal for me so returned - Spent quite a bit of time researching and setting up the system. Technical support was very helpful. The system was operating correctly but did not improve my Verizon cell signal despite many days trying to make it work. So I returned it. Review: Cannot be registered with Verizon if you have a prepaid account. - This device works great. It's exceptionally easy to set it up. But, if you have a prepaid Verizon account, you CANNOT register this device with them (VERIZON) and will be in violation of FCC laws. The only way you can use this device is with a postpaid account which is more expensive (in our case $50.00 per month) and offers less data traffic. Nowhere on Verizon's site do they advise you of this. Cel-Fi does not provide this information either.

Technical support was very helpful. The system was operating correctly but did not improve my Verizon cell signal despite many days trying to make it work. So I returned it. ### ⭐⭐⭐ Cannot be registered with Verizon if you have a prepaid account. *by S***B on November 5, 2019* This device works great. It's exceptionally easy to set it up. But, if you have a prepaid Verizon account, you CANNOT register this device with them (VERIZON) and will be in violation of FCC laws. The only way you can use this device is with a postpaid account which is more expensive (in our case $50.00 per month) and offers less data traffic. Nowhere on Verizon's site do they advise you of this. Cel-Fi does not provide this information either. Caveat emptor! ### ⭐⭐⭐⭐⭐ It works as described! *by J***E on March 18, 2021* Finally a solution for our cell phone problem, AND for once a product that is truly plug and play! Started with minimal service and 'bars' in our rural western NC location (we have Verizon). Bought a different product with professional installation and an outside antenna, did nothing. Went back to Amazon to find something else to try and found this. It appears you must make sure you buy the specific model for your cell company. We had 2-3 bars and could not make a call unless we stepped outside in the exact corner of our deck, and even then people got every other word, frustrating to say the least. So... it arrived and I was cautiously optimistic. From research online some reviews say you must have a 4G or LTE signal on your phone or it wont work. My iPhone only showed bars so I was not sure the type of signal I had until I turned off Wi-Fi, then that icon went away and next to the bars my phone then had space for the signal type, mine showed 5G. Followed directions and placed Network Unit upstairs as far from downstairs living room as possible, and in a window with some cell coverage. Waited until it 'locked on' to signal. Plugged in Coverage Unit and waited a few moments, a 4 showed on display, optimum is 8 or 9 according to directions. FULL bars on phone, calls crystal clear!! Now after about an hour display is showing a 5, good enough for me, not going to touch is or move it. $650 not cheap but excellent call quality and an un-frustrated family makes it worth it! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/96479853-duo-verizon-plug-and-play-smart-signal-booster-for-home](https://www.desertcart.tn/products/96479853-duo-verizon-plug-and-play-smart-signal-booster-for-home) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-07*
