Please note this review is for the ZTE MF920U, CAT4/4G LTE Mobile Wi-Fi device and not any of the other ZTE models you can find on Amazon. Secondly, I am not a computer / technology nerd, so my review is based on my experience of setting up this portable hotspot device and is meant to help others who may consider themselves less technically inclined avoid some of the pitfalls I encountered.I initially bought this device as I had recently acquired a general use SIM (i.e. one can use in a mobile phone for making calls, texting and having data for accessing the internet) from a well known brand to use with my old portable hotspot or in my Samsung Galaxy S6 Lite tablet. Sadly this general use SIM didn't work in my unlocked devices, so I decided to buy this ZTE device as it offered a 4g/LTE service. However, I then discovered the general sim didn't work in it either (i.e. it wouldn't give me internet access when I tried to link my Amazon Kindle, Windows 10 laptop or Samsung tablet to it). Further research and contact with the helpful folks at the general SIM provider led to a suggestion I should change the APN settings in the ZTE device but this also proved unsuccessful.Lesson 1: Use an appropriate 'data only' SIM (that for me meant one that offers a 4g/LTE service which is what this particular ZTE model and my Samsung need). Funnily enough, Smarty offer a 'data only' option for the free Smarty SIM provided with this device!Assuming you can get a good coverage from Smarty in your area (this can be checked on their website) and before you can use it in this device, you need to create an account with Smarty and select a data only sim package via the Smarty website.Once you have created an account you then need to activate the SIM which took just 10 minutes (but you are warned it could take up to two hours).Lesson 2: This ZTE device uses a 'micro' SIM (the Smarty SIM card comes in a standard size but it is easy to punch out a micro or nano sized SIM from it using the perforations provided). Do not try to fit a nano SIM in the device as you will probably have difficulty extracting it when you discover it doesn't work).Lesson 3: The activated Smarty SIM worked first time in the ZTE device and there was no need to change any APN or other settings. An Internet connection was immediately available on my laptop, kindle and tablet once I looked to see what wifi networks were available. Please note that I am not advocating that only a Smarty SIM will work in this device, as I suspect that other 4g/LTE data only SIMS offered by other mainstream providers will probably work too, but after my experiences, I would be a little cautious about trying to use a more 'general' sim that offers phone and text services in addition to data.So now the ZTE is up and running smoothly, and my stress levels have receded, I am finding this ZTE device a delight to use. It is still early days, but so far so good. I am getting a good signal where I live with reasonably fast download speeds that are good enough to live stream television programmes, etc.In Summary: I hadn't realised how careful one needs to be when selecting a mobile wifi pocket hotspot and pairing it up with an appropriate SIM, so I hope this review is helpful if you are considering buying the ZTE MF920U, CAT4/4G LTE Mobile Wi-Fi device.

I needed a mobile hotspot that allowed multiple devices to connect at once in a hurry as my internet went off at 7am on Saturday morning and I was scheduled to work from home that evening and my son was on call for his Tech Support job. No way we could have worked without internet and as our ISP advised it was an infrastructure fault and would not be fixed for several days it was a moment of sheer panic (finally got our internet back Tuesday at 5pm).This little device certainly came in clutch and proved surprisingly powerful.We live in a two bedroom terraced house built in 1905 so has substantial walls and floors/ceilings. Set this up in my sons room and we had no issue connecting his laptop and desktop PC, my laptop and the husband's desktop. This allowed my husband to stream films whilst I worked, allowed me to take and make phone calls over VOIP and dial in to the office server and perform all my tasks, all whilst my son did whatever he was doing online whilst waiting for a work call.The connection to the devices was simple and strong with little to no drop out. We used the included SIM card and adding unlimited data was quick, easy and surprisingly cheap. Signal strength on the network for our area was good and easily coped with everything we were doing.Wish I had got one before now for when we go on holiday as hotel wifi can be notoriously patchy. Now we have this little device that is never going to be a problem again. Even better we are going to keep this charged with data and make sure the battery is charged then if there is a power cut we can still connect devices and get online quickly and easily (providing they have charge of course).Don't wait for the worst to happen to you (like it did to us) be prepared!

ZTE U30AIR 5G Wi-Fi pocket Router – High-Speed 5G Connectivity, Dual-Band Wi-Fi, Seamless Streaming & Gaming, Easy Setup, Portable, Supports Multiple DevicesI recently updated to this from a cheap 4G ZTE mifi which served me well for 2 years. I use it with an unlimited payg data sim to avoid the financial enslavement and ever worsening service that comes as standard with UK broadband contracts.Previous routers and mifis all handily had the password on the back. With this one it is so well hidden that Amazon customer services had to help me locate it. Finding the password involves taking the back off the mifi (every single time). The plastic clips holding the back on don't seem overly robust. This necessitated a diy approach where I made my own sticker. This avoided repeated dismantling during that period where I was finding yet another item that needed the new password to connect.My previous mifi could easily be propped up. Not so with this one. The addition of a phone holder overcame this nicely.This mifi has an energy saving feature where the lights indicating charge level and signal strength turn off to save battery. There is no override, apart from to manually press the on button to see the lights for a few seconds. Consequently it does often run out of charge as I have forgotten to check it. When charging the indicator lights do stay on. The charging light flashes and changes from red (deceased) to blue (so so) to white (yay! ready to go all day - maybe). The white status doesn't differentiate between only just turned white and fully charged. If it is only just on the white it will not last the stated time. Unfortunately when taken off charge the battery indicator will just show solid white so there is no way to ascertain if it is really fully charged.I am on the edge of a 5G area. It should only work outdoors. However, I am consistently getting 5G via this mifi indoors, in a concrete / metal building with other floors above, and several buildings and half a mile between me and the 5G mast. That seems quite impressive.This was the cheapest 5G mifi I could find from a reputable manufacturer. Despite the secrecy over the password and charge level display it's good value for money and performs very well. Recommended.
