Very good router for the price and 3 year warranty! Worked great for 18 months but had a few technical issues which were resolved swiftly by customer support who sent a replacement upgraded version as was still under warranty. Can't praise them highly enough. Silvia especially

I bought it, because I didn't want to pay for an expensive broadband. I bought a chip, inserted and it works really well. I have internet at my apartment, connecting a few devices at the same time with no issue. Signal is strong enough for my usage, I can use 2 phones, smart TV, laptop, indoor camera all at the same time and it works perfectly.

Wifi from mobile data. Easy to set up just add data sim.

This device had a lot of promise and delivered some of the potential.It was great at the routing function, provided a good wireless signal and was easy to set up via the webUI and was a neat little device.However, even though it easily connected to the mobile network using my Smarty SIM, it failed to deliver more than 3 kb/s throughput.I took all the available firmware updates, checked all the settings and took all the advice on offer, all to no effect . When I checked the SIM in a different device it functioned as expected.I was disappointed to have to return this device as it should have fully met my requirement.

The first thing to do is have a stable test environment, where you can repeat tests. Also ensure that the 4G router is correctly configured for external antennas.1) First test was to find a repeatable position, where reflections are minimal to movements made in the room.2) Go into the router configuration and enable ONLY External Antennas. Do NOT set to Auto, as both internal/external antennas could be enabled or the router could keep switching between them.3) When fitting antennas, ensure the small SMA coax connector is done up tight and secure. Even slightly loose could mean poor RF connection.4) In the router settings, find a signal strength reading. around -70 dBm is excellent, higher the value the worse the signal strength5) Repeat tests more than once - also remembering that the signal strength indicator can take a few seconds or more, to update. It is not an instant real-time reading.6) Depending on the router, you may need to reboot to initialise the antenna configuration changes.Based on this, I then completed a number of tests using the internal and external antennas. The router was kept in the same position.Internal (typical; -79 dBm Good)External Paddle type (typical: -69 dBm Excellent)External Patch LTE Antenna with RG174 coax (typical: -76 dBm Good)The paddle and patch antenna is directional. Moving them slightly can make a difference. Also rotating from the upright position can also improve, or not, the signal - due to polarisation changes.When using the paddle type antennas, these will make direct RF connection to the wireless in the router.The Patch antennas which typically have a cable using RG174 coax, may well offer, or advertise, high gain but you MUST remember that the coax will be lossy and in fact, you could easily lose 3-6dB due to coax losses.NB. The advertised '35dBi SMA 4G LTE Antenna, SMA Antenna Indoor Network Antenna with Dual Mimo SMA Male Connectors', performed appallingly, as seen above.Finally, depending on where you are sited, signal reflections do exist and sometimes pointing the antennas in a odd angle can provide surprising results. When testing in the hotel, I had a better signal tucked in the rear corner of the room, than by the window.Conclusion, direct Paddle antennas provided the best overall performance. Hope you found this of use.

Bought to provide a second internet connection using a Three SIM with unlimited data.It works. But the the internal antenna are obviously pretty weak. Running speed test using the same SIM in my phone (a couple of years old mid-range Xiaomi phone) gets FAR stronger results than this thing. Where my phone returns an acceptable speed, in exactly the same location this thing is so slow it's unusable and constantly drops the connection.In other parts of my house, where reception is stronger, it fares better, but is still slower than my phone. In the end, had to locate it high up in the corner of the room it's needed and the signal is acceptable, although by no means fast.I only use it via an ethernet cable connected to a single device, so I can't comment on the wifi strength. But it seemed OK for the brief few minutes it was switched on.The web admin interface is a bit clunky. Not sure port forwarding is possible with it. I couldn't find any options for it.And, as someone else mentioned, it does die completely now and then and needs rebooting to restore connectivity. Thankfully, a software reboot via the admin interface seems to cover it. So I now have a little script than runs in the middle of the night when it's not busy and resets it for me. Without that, it would be incredibly annoying randomly losing internet every now and then. Mine lasted about a week before it needed a restart. Had my script running since then and no problems.So for what I need it for, with a bit of faffing about, it's just about good enough. Would I want it as my main internet connection? No.Would I recommend it? Maybe with caveats. You need to be in a strong signal area. And you need to be prepared to restart it every few days. If you can live with that, go for it.

I wanted a wifi router with sim card that works well...and it did serve the purpose..Great item.
