TP-Link M7200, CAT 4, 4G LTE MiFi, Portable Wi-Fi for Travel, 2000mAh Battery for 8 Hours Usage, Manage with tpMiFi App, Comes with FREE SMARTY SIM Card + 3 Year Warranty- Black

Works very well on giffgaff. Mine came with a Smarty SIM as this bundle was on a Prime Day sale, but I haven't activated that so my review will only be referring to the device itself, with comparison to its predecessor.It has the same shape and size of the M5350 3G MiFi however I have knocked 1 star off as the M5350 had a far better display. At a glance you could see the signal strength and type, battery level and number of connected clients and unread SMS. This, on the other hand has 3 LEDs, which simply correspond to power on (flashing for charging), internet on and WiFi on. I haven't yet seen how, if at all, it indicates a low battery (update: it doesn't).The firmware on this is, for the most part, far better than the M5350, with one glaring exception. If using on a PAYG network and only lighting up a bundle when one is needed, the M5350 had the rather nice option of Manual connection, that is after power on you had to log into the device to connect it, but it wouldn't auto connect next time it was switched on. This one, on the other hand, just has a mobile data on/off toggle requiring that the user logs on via the web page or tpMiFi app to actively switch off mobile data when session is complete. The old Manual connection option is also useful for keeping the SIM alive by being able to turn the MiFi on without automatically connecting data, just briefly connecting to show some activity at minimal cost (for example giffgaff PAYG data is 1p/100K) so it looks like I need to find a different way of working with this unit.Now to the speed and performance. In my brief testing on the tail end of a bundle, once it was working, the latency is on a par with domestic ADSL and throughput is excellent, often faster than ADSL home broadband. I did have to go into the configuration and change the auto-detected APN from O2 PAYG to giffgaff, but I guess that isn't too surprising for an MVNO on O2.

It arrived on time. But I was busy so it took a couple of days for me to look at it properly. It comes with basic instructions. Which most people would now if they have a mobile phone.What it doent tell you is that you have to buy a plan before the sim is activated. Plus all the other things you have to do to get it to work. Oh by the way I've done all that and it still doesn't work. I bought it because one of the reviews said that it could work out in the woods where there's no Internet at all and where I'm staying the connection is very bad so I survive on data. It took 4 hrs to set up and get nothing not even a hiccup. Don't waste your money and time.

Bought a static van and needed WiFi. Bought this to give it a try. Excellent. Good value for the basic item. Top up not expensive and even better……if you recommend Smarty and someone. Ups with yoru link you get a free amount of data. Could not fault this and would recommend.

It worked a bit for a couple of hours, then it didn’t. Next day the same, and subsequently it has provided zero internet signal. I tried resetting it, re-seating the provided Smarty SIM card, re-charging the battery that lasts about four hours, all for nought.Not one of my finest purchases, i might purchase an air rifle and use it for target practice!

I recently had a massive problem with my broadband service and decided I needed a backup plan to ensure my ability to work from home. This provides that security as such a great price. Set up was simple - download the tpMiFi app and connect to the device. I've signed up to Smarty, tested that everything works and now the unit is back in its box ready for action whenever it's needed. Maybe it will never be needed but it provides great peace of mind. I can also take it on holiday. 4G speed is more than adequate for most needs.

Great little box for out and about, good battery life and good for creating a good and stable 4g hotspot.Only had 2 phones connected at a time and it worked well for streaming Netflix and YouTube.Maybe not as good signal wise in poor areas compared to routers with external antenas bit considering you can take this out and have it in your pocket all day its a great little gadget for the money.Well worth the £40 price tag on it.

I get a good signal throughout the house and it works well when in my pocket and I’m outside. My previous mifi dongle stopped working with my Apple iPhone for no reason. Very happy with this item

Poor Product, experimented with the device over several days, and had others try also. Device kept dropping signal and wifi, and I had to keep playing with it to get the WIFI working again.Did not appear fit for purpose, I was very disappointed, and I note MANY negative recent reviews where people had similiar experiences to mine - Mobile phone works better with the same SIM card, and does not drop the signal.Avoid
