Unlocked ZTE MF286D CAT 12 600mbps 4G+/LTE Home/Office Router (White). 2 x RJ11 Tel Ports. 2 x External Antennas. Works with any Mobile Network Sim Worldwide. 2.4/5GHz Wi-Fi + Bridge Mode (Renewed)

Brilliant router. Simple to set up and use. This is the second one I have bought as I needed a separate one for my office / shed.

Fantastic product at a very good price point. I needed a mobile router to couple to an external antenna for use on a narrow boat. This item works faultlessly.

Works ok . Bargain price quick delivery.

This item was sold with a smarty card. so i duly joined smarty for my internet service. I started experiencing problems, buffering, dropping out, unable to access email, and apps on and off. contacted seller who after some dialogue informed that the service carrier must have blocks on and i should request removal, which i did, but problem persisted.after more dialogue i was told that the problem due to the fact that Smarty piggy back off the 3 network and that the router was only finding a signal on and off . i was sent a link and told to follow the instructions and the problem would be fixed. followed the instructions and continued to have the same problems.decided to try the sim card in another router, worked perfectly. went back to seller to inform that as i had previously indicated i believed the router was faulty and requested a replacement.seller came back saying that the service would only be as good as the service from the provider.i contacted amazon customer service who initially informed me that they would contact seller but in any event after 48 hours i should make A-Z claim. only to find on trying to make the said claim it was denied as the 90 day deadline had passed . i am left with a very poor internet service , having wasted hours contacting seller, amazon customer service and no way to remedy the problem. last word from Amazon was a suggestion that i should claim back through my bank. sounds to me like dereliction of duty

Purchased this as I am going to give mobile broadband a go. Ordered the refurbished acceptable from Eternal Uk Grade C as it was a third cheaper. On arrival item was immaculate and marks on it probably happened during transit in the cardboard box and could be easily wiped off with a damp cloth.The set up instruction on Eternal's website are detailed with every uk mobile providers APN information provided. However I didn't need this as the router auto detected the three sim I was using and set itself up accordingly.In terms of performance with the same sim my phone (Moto G31 4G), could only achieve 40-50 Mbps in speed tests. The router dependant on time of day scores between 55-95 Mbps The ext. antenna's do increase the performance as testing without results in a 30% speed loss. This is based on around 350m no direct line of sight to the mast.The only negative I can cite, is that on powering up the router failed to update to the latest B14 firmware. Based on some searching I believe this is because the unlocked Nordic B12 firmware installed was created by a user on the ISPreview forums and is not fully official causing the newer update to fail on verification before install.This is not a problem for me, hence no change to the star ratings, but I have flagged it in case its an issue for others who might be about to purchase.

First of all - the corded phone adaptor is flawless besides an annoying extra two seconds before it waits to dial. My mum, who is going deaf, says that the audio quality on a 20+ year old handset is flawless. She sounded very clear on my end too. If you're buying to replace a landline - just get it. That matters more than all the fluff below.There are all kinds of software problems that ZTE have worked very hard to stop you from ever fixing for yourself. The antenna configuration is utterly bizarre - only one of the ports is actually useful in the UK as far as I can tell* - even though it uses 4 antenna MIMO internally.The firmware update process does not work.The band lock system does not work - the modem will forget carrier aggregation after a few hours.Carrier aggregation !!slows down the uplink!! whether or not you have 'uplink carrier aggregation' enabled.**But the default state the modem falls in to is ultimately more useful for most purposes - download speeds that are merely good and an uplink that is great.Obviously this all varies immensely depending on what kind of cellular service you can actually get. If you're just getting a single, 20 MHz wide carrier (EE does these sometimes - three uses 15 MHz almost everywhere though) it will be very fast up and down.If you're aggregating say, 5+15, you'll only get the 5 MHz uplink speed. With my signal quality on band 28 - that's 10 Mbit/s.So I have to chose, because of a bug ZTE doesn't want me to fix, between speeds of Down/Up 140/10 and 75/25.The latter is the 'default' and it's generally more useful (a faster uplink improves the received video quality for other people on a zoom/facetime call, for instance).If pretty much all of that went over your head, you may well want to get one of these because the internal antennas get a nice strong signal in places it really shouldn't! Plus it does just work when you plug it in!*ever seen 2600 MHz B7/B38? Me neither.**In fact this option does nothing at all.

The unit I received was in "as new" condition and was unlocked for all networks. It was originally a "three networks" device but has had its firmware replaced with the Nordic_MF286D_B12 firmware which unlocks extra features and gives you more information about the cells you are connected to and their performance. Lots of help included with the device in case you need assistance and a free O2 SIM from Eternal Communications in case you need to avail yourself of a UK unlimited SIM plan. All in all, great value and the unit works superbly for a 4G unit, pulling a download speed of 50-80 MBps in my area using a Three SIM. Couldn't be happier with my purchase!
