Review: Espero funcione - Necesito contactar a la empresa. Seguinos pasos y si, logre el sitio de mejor señal, pero a la hora de enlazar la antena a mis dispositivos no se detecta
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)**
A: Por favor comuníquese con hello@elsys.com, le informaremos al contacto el Chile

### ⭐⭐⭐⭐⭐ So far, so good!
*by E***. on 18 November 2024*

I bought this to replace the Verizon wireless modem I was using at a remote rural property. The internet performance was mediocre at best with frequent drops. I bought a SIM card at Verizon and started a new data plan so I could use ELSYS. Setup was relatively easy using an external pole mount from Amazon (https://www.amazon.com/dp/B0B217C418,) and the results are tremendous. It was easy to determine the location of the best signal and orient the antenna. The improvement was noticeable and I'm now able to live stream from my cameras remotely with almost not delay. Only time will tell as to how weather-proof the antenna is, but right now, I'm extremely pleased.
