GL.iNetGL-XE300 (Puli) 4G LTE Industrial IoT Gateway, Router/Access Point/Extender/WDS, OpenWrt, 5000mAh Battery, OpenVPN, Remote SSH, WPA3, IPv6 (EG25G), Global Version

Pros:a lot of advanced features, very convenient & eazy to useI loved the VPN Killswitch, multiple internet sources 4G-LTE/LAN/WiFi-repeater which could be compined togetherCons:1- it lacks USSD codes support2- The IMEI is not printed on package/device, however IT IS printed on the chip INSIDE the device, in some countries they require to see a physical IMEI for duties and registration purposesOverall: very useful, i bought another one, it is worth every penny :) 4.7/5

It's only been about fifteen minutes since I opened the box and this thing is already up and running. It could not have been any easier and it makes me wonder why the four or five different mobile routers I have tried never worked - because this one took about two minutes to configure and start using. That's not an exaggeration. I am typing this on my laptop that's connected to this router. It was amazing.I thought that this seemed a little expensive, but I'm glad I got it anyway. The ease of the setup was totally worth the cost. I haven't yet found anything to complain about. I'm beyond impressed.

Sometimes it got disconnected for data networks.

I received the unit and tried for hours to get it to mount and read either an SD card or a USB thumb drive. Neither worked. None of the online help and forums addressed the issue. Everything showed that it should have an internal application that read the drives as network attached storage. It didn't.I reformatted, reset, and rebooted the unit dozens of times. I updated the internal packages. I used the pc interface and the android app.UPDATE:I contacted customer support. They replied, "Sorry for the inconvenience caused. The file sharing feature has been removed from firmware V4 due to the short of the memory space.​If you want to use it in firmware v4, you can follow the post here to restore the feature by installing plug-in packageDue to the insufficient memory storage, you may need to us a micro SD card or the USB drive to expand the space through exroot method. Here is a related setup tutorial at how-to-add-a-usb-drive-or-a-sd-card-as-overlay for your reference."So, I purchased an microSD card and spent two days reading on Linux commands and OpenWRT. I got the microSD card mounted as part of the system memory. I installed the necessary packages to get the USB readable. This also means that the microSD card is no longer usable as external storage. This was a big selling point on the website and Amazon. So, beware false advertising.This also doesn't have a native FTP server like some of the other brands do. That took roughly a day of programming to make it work.Moral of the story, this is a product that is limited by its internal memory. You will have to spend time and money to get some of the key selling points to work. If you are a programmer and you want a project. Have at it. If you want a plug and play solution, look elsewhere.

The device accepted the SIM card very easy and has not had a hard time connecting every time it is turned on.

This has got to be one of my top products received from Amazon. Seriously.It took about 3hrs of finagling due to the SIM card and, well... me, but when it works (which is hit or miss regarding the modem), it's a pleasure to operate and have because it provides a nice clean connection with a VPN included... where ever I go.In the box, there is the device (mine had about 45% battery charged in the box) a USB-C power cable... which means you can charge this with a normal USB-C cable, and that's awesome ...and a couple of adapters for the region you are in.I think it's because I got the worldwide version, but to me... that was a pleasant surprise to see that they had included a few adapters for different countries and power grids.The device itself is small, small enough to throw in my pocket. It's quiet. It's unassuming, I mean there are lights but I doubt anyone would know what it is if you didn't tell them. It's not flashy... and I personally like that everything is low-key. It also does its job quietly, which is nice. On top of all that, there are two ethernet ports onboard the device which give you the option to WAN one or LAN two.As for performance, well... you get a 3g/4g connection so if you are used to 5g speeds it's going to be a step down. With an AT&T sim card I was getting around 16mb down, and 10mb up... which is good enough to run what I want to run.This leads me to my reservations about this product, and there are a couple.First the wifi output is only 2.4ghz and there is no 5ghz radio or option to enable it so naturally you end up with a lot of interference as nearly every IOT device in my house runs on 2.4ghz. If this was a travel orientated router... then why not add the second channel with a wider channel selection and a shorter range?Next similarly why no 3g/4g/5g? I know that would shift things from where this was aiming to be, and that's a great place... it makes travel modems very accessible where it is, but especially being a product released and marketed in the US alone, 5g is becoming more commonplace... so why was that left on the table.Finally, just a small gripe... let people know this takes a second to get going, because it's really confusing to start this and nothing happens for a good 5 minutes. If you never turn it on and off... you may not realize, but without sounds or lights or something that says "Getting Started" it seems like it's not doing anything when it's actually not booting but finding a connection with the modem.Which further reminds me that there's even more that this device can do, like route WIFI and act as a router with OpenWRT... and so yeah... I love this device even with some of the odd choices with the radios and channel capabilities.
