HUAWEI E5573Cs-509 up to 150 Mbps 4G LTE Mobile WiFi (AT&T in The USA, Movistar and Movilnet in Venezuela! Europe, Asia, Middle East, Africa & 3G Globally) Original/OEM Item from

Network: US T-mobile. I plan on taking this camping in RV this week. We will be on outer skirts of decent signal. I bought the dual MIMO TS9 external antenna setup to place outside my tin can travel trailer. I will update on how it pulls in signal or not with external antennas.EDIT: It worked while camping with the external antennas albeit with some trial and error. Service with our cellphones was very sporadic- even outside trailer. I ended up placing unit on our car roof with antennas where I was able to get two bars and LTE lock. We were able to stream Netflix but used it mostly for work laptop.

Connects fast, long lasting battery life

Overall, don't waste your time. Product deserves 0 out of 51. Directions are in spanish only, but I could deal with that2. Continuously powers off3. Will not recognize any AT&T SIMs I have on hand (all work on other devices, including hotspots)4. Default admin credentials provided do not worka. Google search did not provide any answers5. Connection splash page gets stuck in a random loop when trying to access while connected via USB

I bought this hot spot to allow me to monitor my home's temperature and security sensors when I leave my New England home in the winter for warmer climes (this allows me to substitute pay-as-you-go cellular service for my expensive internet). The Huawei E5573Cs-509 was a little difficult to set up (instructions are terrible, but there is sufficient information included to allow a knowledgeable person to get it working). I found that its Wifi router has good range (not quite as good as my main Asus router, but good enough to reach all my sensors) and the AT&T cellular reception is as good as my phone. I leave it plugged in all the time (battery life is not great) and, after a couple of days, service has been perfect (no resets required). We had an electrical storm last night which interrupted power for a few minutes, and the battery carried the unit through the outage without a glitch. My cellular data-only plan from FreedomPop gives me 200MB of free data per month with overages at 2.5 cents per MB; I figure I'll be spending less than $10/month instead of $90/ month for internet while I'm away! I'd give this product five stars if it had better set-up instructions.

I am impressed with this Hotspot. It works with T-mobile card in my area. I tried Tracfone, but it doesn't work. As a range extender its fantastic. So far, so good. Battery life is great too. Fits into my pocket. Love it.

I am on Google Fi, just at the edge of my service area. At home, some calls drop, and it takes about 5 minutes to load the weather channel on my phone. Enter this great little MiFi device -- what a game changer! It concentrates the signal to such a degree that I can watch videos on my laptop. I had no problem getting it to work with the Google Fi data-only SIM. HIghly recommend.

I purchased this to take with me on a trip and use my T-Mobile signal, however, the device appeared to have poor cell reception. I had full bars on my phone, while the hotspot had only 2 bars. This difference in quality could also be felt in the speed of the device, as my phone pulled down 70Mbps and this device provided me with just 10Mbps. The band my phone was connected to appears to be supported by the hotspot, so I am unsure of the cause of these issues.

Tried it in both US and Switzerland. The download speed was over 100 Mbps with my regular T mobile line. The download and the upload data rates with Swiss operator Sunrise are around 50 Mbps both. Very satisfied with the stability of the connection. With moderate mixed use of texting, uploading/downloading photos and web surfing; the battery lasts a bit more than 4 hours. Be aware that this unit does not support the band 20 (the 800 MHz low frequency hence the long range) for Swiss LTE, but supports the other two high-frequency LTE bands (3 and 7). This might be a reason for lower data rates in Swiss than the ones in US. However, I did not observe a single glitch in my car even when passing through Swiss motorway tunnels.
