I bought this when on offer to use as a back up in case my Virgin broadband goes down. I bought a Three data sim from Scancom, popped it in and away it went. Worked straight out of the box! I think they are cheap because they are only single band although advertised as dual band. This is not a problem for me as only used now and then but for those intending to use the item as their main router you may want to think about buying a better quality dual band router. It is very very light and can be knocked over easily so needs to be placed out of the way. I found that I get the best signal in my back bedroom and it works fine. Three is not the best of networks though and signal strength varies enormously. Other networks are much more reliable. I have used it with a Poynting 4G antenna and it makes a real difference to signal strength. I would stress that if using an external antenna the setting has to be changed using the app as otherwise the router will not know it has an antenna attached. The setting also has to be changed if the antenna is removed as otherwise the internal antenna remains disconnected. I found the app to be excellent. Easy to use and well laid out. Overall I can really recommend this item but with the reservation that it is single band only. For the price you cannot really go wrong.

Absolutely brilliantWorks with EE Sim , very quick to set up , no problems at all

After using the router which I bought as a package with a Smarty SIM (3 network). I was apprehensive. With all of the 3 issues of the 90s, 00s it was a network I have swerved for decades.Seeing this deal, I thought, surely they couldn't be terrible still..wrong! They are still the pits. I actually thought the router was the issue because of the cheap price, but after many many many nights of frustration with ASD children, meltdowns and tears( mine) because I saw the pain and frustration in my child's eyes, I used the sim in my phone. After spending 2 months ( I forgot to cut off the reaccuring) I ended up having to use my phone as a hot spot for the first month is support of the sim for my devices and then fully take my sim out of my phone and put it into the router for the second.Immediate stable connection, all lights on.A bit laggy at times, but a lot better than everything buffering, even watching Now TV, which needs about 8bps to watch was just impossible.The router is fine, just get another sim to use with it.The router itself is small, and easy to connect. The idea of being able to take it everywhere is a game changer, especially if you travel and sometimes the broadband isn't very good.

Bought because it seemed a good price for a router that has external antenna connections if required as i use this in a camper van. I did buy some rabbit ear antennas just in case, but not needed them yet. The external antennas need activating in the app (easy to do) otherwise they won't do anything. Happy with my purchase.

We moved house a week before Christmas and was advised the broadband wouldn't be installed until mid January. I bought this with a smarty unlimited data plan for the month and told the kids not to expect much. It works perfectly, the signal goes all around the house and have 10 things connected at the same time with little to no lag.Setup was simple and easy to configure via the app and just generally a great product.

Impressed by not so easy setup to identify type of product at start of app :- setup process, initially it didn’t work until I selected the product setup product setup as “router”, did it the find the device:- after which it was then straightforward menu-driven setup.Once nano SiM orientation figured out and inserted, all lights turns solid “green”:- all ok and works like a treat , it’s 5G reception indoors, good reception of 5G, to my surprise getting 5G, it’s powerful enough t to pick up 5G signal indoors, happy with this, from past experiences this was my look-out for in routers with 5G providers SIM, at 5hz instead of 2.4 hzConstant power supply via plug is added value instead of battery powered router.The router box sits steady on table or flat surface which is a plus, RJ45 cable supplied is stiff and short for connecting to a WiFi- router when this is used as a repeater, ( paradox ), 2 routers in series.But works, no conflicts, connected netgear m2100 to this router: compatiable n works!!Please with promotional priced for SIM - router device,Reception signal pick up indoors good, all green lights on side of panel!A bit pricey for old technology but with broadband prices for wired broadband these days, SIM based broadband is a way of cutting unduly high cost of broadband without the added long term contracts, this setup n configuration adds value to you as a user! Would have liked the upload speed to be faster at 20 mb/sec! But trolled by provider of services! Otherwise product device meets expectation of 4G router

This thing is a lifesaver, I can’t believe I was paying for home broadband for all those years. Bought this and a popped in a cheap payg sim with unlimited data and it was ready to go. Perfect for students or people who move around a lot. No line rental and no credit checks, what’s not to love. Can’t fault the speed but I think that’s more down to the sim. Used at home and during a long hospital stay when my phone didn’t have any phone signal

Purchased for when we are in the caravan. I add an unlimited sim to my account and assign it to my current contract and then place the sim in this. Fantastic bit of kit especially when I attach the screw in extended booster purchased.
