Review: So Much Promise, Now Delivered! - One Year Later: I have been using this product mounted to the top of my motorhome for over a year now - continues to provide great connectivity with my ATT SIM. At this point I couldn't recommend this product more. Better signal and coverage that an internal 4G modem. Edited Review: Although I had given up on this device for my use, i was contacted via email by Elsys support after Christmas. I relayed my experience in detail and they felt they could guide me to get it up and running and asked to send me another unit, which I accepted. Once the new unit arrived I updated the software and got to the same "non-connecting" point with my known good AT&T SIM. I provided a detailed explanation of what I had done and screen shots for documentation. With a few hours I got an email from their Tech Support/Engineering asking me to run a few commands on the device to "clean out" APN data, restart it and see what happened. The instructions to run the commands were crystal clear. Once restarted, the Amplimax immediately connected and I was up and running with a much better signal than I had with my previous LTE modems. This took less than 15 minutes of my time. I am completely happy with this device at this point. Original Review Below: What a great idea! Minimize the loss between the antenna and the modem for a better connection solution. Didn't work for me. I have an AT&T data SIM which works in 3 different modems including 2 Netgear modems. It would not connect in two of these Amplimax modems even though the "blind search" showed the AT&T signal level at 84% to 92%. I went to the Amplimax website looking for Tech Support help in resolving this issue. There is no support to be found including no way to contact them on their "Contact Us" page. I sent an email to the "support" email address found in reviews and questions on this page - no response after 72 business hours. So although I was really hopeful to make use of this devices' claims of better signal strength and connectivity - it is useless if it won't connect and you can't get manufacturer support. So I'm back to using the Netgear modem with external antenna and mediocre signal strength - but at least it connects me to the Internet (most of the time).
Review: UPDATE: Worked for 30 days then stopped - UPDATE 5/24/23: Asurion approved my claim over the phone but never sent email confirmation with return info, which turned out to be a good thing, because Elsys finally got back to me 3 weeks later via email. They apologized for an internal issue that kept them from accessing customer emails, and have been VERY helpful over the phone since. They explained there was an issue with AT&T as a carrier in particular, and that I needed to do a software upgrade to use my AT&T SIM card. However, since I couldn't connect over AT&T, I had to wait three days for a random "connected without internet" to happen so I could login to the Amplimax IP address and do the upgrade. Internet is now back, but it keeps disconnecting every hour or so which is fixed by powering the Amplimax on and off. Customer support is currently looking into why and seeing what settings (APN) might need to be changed to fix this. So even with internet back they are still trying to help improve the service. Very glad they reached out and the troubleshooting help! FYI for anyone using Verizon data plans, they said they are in the process of working out a few kinks with Verizon, so if you're having trouble use T-Mobile or AT&T. And/or do a software upgrade if you're having issues when everything else seems to be working. ************************************************************************************************************************* At first the modem worked like a gem right out of the box. Did the signal scan and saw At&T was the strongest at 88%, bought a prepaid AT&T cellular tablet data plan, popped the SIM card and was FINALLY able to use a VPN for my work and have strong Zoom calls. I was so excited to have a solution to rural internet. However, after a month the device stopped working. There's no error message about the SIM card, my data plan is active, my router has no error messages and the wifi network still pops up, but any device I try to connect says "Connected without internet." I even bought another prepaid plan thought H20 wireless (a sub company of At&T) to try. It randomly connected for 24 hours one day, but that was it. So now I'm paying for two prepaid plans and the modem is not working with either. I emailed Elsys customer support a week ago, but no response. My desertcart return window expire two weeks prior to the device failing, so now I'm trying to replace it through the Asurion protection plan I bought through desertcart. Fingers crossed, because this WAS the best internet I've had out here in the country (wait listed for Starlink, satellite internet has extremely high latency and speeds less than 10 mbps, no fiber optic options out here.) If customer support was better there might be a way to further troubleshoot, but I've tried everything in the manual that came with the modem and the manual I found on their website. Great concept, but it needs tweaking and/or better customer support to actually work.

## Questions & Answers

**Q: Hola buen dia, me sirve para colombia?**
A: Si Sirve correctamente

**Q: Will the device work with a google fi account?  i am considering the simply unlimited plan for $65 per month which provides 50 gbytes as a hotspot.**
A: I am not at all familiar with Google fi.   If Google fi uses a sim card I would think it would work.  I have a variety of LTE sim card routers and setting up my Elsys Amplimax is similar to the other routers.  I use an AT&T sim card in my Amplimax.  Again, not being familiar at all with google fi, it it uses a sim card I would think it would work with the Elsys Amplimax

**Q: quiero comprarlo para Colombia , pero en la descripción dice que es solo para estados unidos , ahí garantía de que funcione en Colombia?**
A: No se lo recomiendo a nadie .,si no funciona ni hay garantía de devolución

**Q: Como poder comprar la versión para operar en Latinoamérica (Chile)**

### ⭐ It says all US Carriers.... But read my review
*by H***L on November 12, 2021*

I have had mine for a 3 weeks now and still haven't gotten it to work. I put in a Verizon Sim card that I was using in a Jetpack. I've been going back and forth with them and this was the last response I received. "Looking at your picture I conclude your configuration is correct. Your Amplimax is registered on the Verizon network, but they didn’t give you an internet connection. If your plan is working correctly, I’m afraid there is nothing else to be done. Unfortunately, we cannot guarantee Amplimax works with Verizon. Would you consider using another carrier?" Haven't had a chance to try another carrier. T-Mobile is not even in my area. I Will update the review if anything different happens. It is not compatible with Verizon even though it shows it as the strongest provider. Couldn't get it to work, however, Elsys provided all the support needed to try and solve issue. They gave me a full refund.
