Mobile WiFi Hotspot | KuWFi 4G LTE Unlocked Wi-Fi Hotspot Device | Portable WiFi Router with SIM Card Slot for Travel Support B2/B4/B5/B12/B17 for AT&T/T-Mobile

It works fine once you change the setting to "LTE Preferred" as another review pointed out.Drawbacks: 1) case really hard to pry open but since I use it at home I leave the cover off, 2) instructions are barebones and in tiny type but you can download a 14- page manual online, 3)no battery charger included, but I already had a mini-usb charger at home.Speed is slow but that had to do with my cell carrier and other traffic on the cell tower, not a fault of this unit.Update: I had a problem with the device during the one-year warranty period (but after the one month return period and seller solved the problem to my satisfaction.

No way to turn on the device - Pressed the Power button did not work. Charged for a full day. All icons were blinking and flashing blue, green, yellow, red colors all day. Yet still didn’t turn on plugged or unplugged. Its manual does not mention the proper way to turn on/off either. USELESS!

It is a compact and precise equipment for what anyone needs, to be connected. I recommend that you evaluate a lot the bands with which your service provider company works, so that you can get to use it without problems. We speak of a team that is set up very quickly and easily. If you do not know about the computer theme, it includes a small manual with everything you need to achieve your short configuration. The equipment comes in a compact box, with its USB cable, battery and instruction manual. To be able to charge it, you must have an identical device to that of mobile phones, with 5 voltages to achieve efficient charging. The first load that is left for 24 hours is what the manual and other users report, that way you can keep your warranty and take care of the useful life of your equipment. You can connect 10 computers at the same time, so you will not have problems to be connected.

I am very disappointed with this router I went oversee and could not connect to the internet.I would return it when I am backThey would not refund me pasts 30 daysIts jank

It was good while it last in the 9 months that I left it plugged into the charger next to my desk. Luckily it managed to work when I first inserted the T-Mobile prepaid SIM card which is sold for USA use. To keep track of my data usage as shown on the tiny screen, it took me many months to find out how to reset the counter to zero whenever I change to a new SIM.Go to main menu, press bottom right corner "Reset" button. OR, press Router tab, then Reboot button. Shut down this router, replug and counter will show something like 3600 B, then gradually rise to MB and GB as you surf the web. If it doesn't reset to something close to zero, repeat the Reset buton process as described.To pay US$50 for 9 months use is pricey, so I have now moved to USB plug-in router which I got for US27. It has 4G but does not show LTE. However, although this KuwFi router displays LTE on the tiny screen, I still could not get any fast internet, very often sputtering when watching youtube movies, or just the CNN video news.I was willing to pay US50 only because it was difficult to find such a router which run easily on USA T-Mobile SIM card without the hassle of tweaking other brands. That is because most routers in USA default to AT&T cards, and only some wiz nerds know how to tweak them to run other brand carrier SIM.

US SIM cards come in 4 sizes (full, mini, micro and nano) which start biggish (full) and get progressively smaller (nano). This device requires a *micro* but I thought I only had a nano. A few hours worth of online and then phone tech suport, and then two AT&T stores worth of waiting for attention later, a smart customer service rep showed me that their SIM card thing (in the photo) can be used for mini, micro and nano. The SIM itself is nano but the other sizes can be popped out and used as a tray that the nano SIM fits into it, then into your (mini or micro) slot. I wish I had realized / known that (or that the Amazon tech support or AT&T help desk support line or the in-person rep at the first AT&T store had known that and told me). It would have saved me a big hassle.So hopefully this review will save someone else the same hassle. The device seems otherwise fine. Takes a good minute to connect, but otherwise - totally fine.Cheers.

It was a small and cute equipment however it was not compatible to the current carriers that I tried to get a Sim card from. So I returned it.

Device works as expected, the battery doesn't last and the when left plug into power source device tends to run hot. That’s something the dealer pr supplier could address
