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

I did enjoy this hotspot on my recent trip to Europe. I used a Movistar SIM also sold here on Amazon; the experience couldn’t be better. The interface works fine thru browser and after entering the device password, and entering the SIM card code voilá, full internet browsing. First, it is extremely difficult removing the battery cover, second, instructions are written in 1mm size and hard to read. My device had a defective SIM card slot, but I was able to use it. It is an inexpensive wifi hotspot and battery duration could get you 5 to 6 hours without charge; it gets a bit hot if you keep it inside a backpack while on. In general, it is worth it especially for traveling overseas having immediate internet connection when you land.

The product doesn’t work! I purchased it in the hope that w would be able to us it in Africa but it didn’t work for me at all ! We bought 3 of them but none worked my girls and I! I’m highly disappointed and I just returned back and I will call amazon because I need my refund asap

Todos buenos gracias

Easy to setup. Problem is that when I try to connect a phone or tablet (no matter brand) connects but dead. No data transfer. Tried many different solutions but to no avail. Definately not worth the raw materials it is made with.

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.

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.

Very good
