Unlocked Modem USB 4G LTE Huawei E397u-53 Worldwide Hotspot Service Required Only T-mobile in US

Despite the reviews I had trouble getting this to connect on the latest Mac OS + Macbook Pro (touchbar). The software is an eyesore from the 1990s. Id recommend looking elsewhere.

I recently moved to a rural area with no internet. I have service with Cricket, so I purchased this modem and upgraded to the unlimited plan. Cricket currently does not have a data only plan, does not allow tethering with the unlimited plan, and does not allow tethering on my phone (Galaxy 5S) so I was pleased to confirm that this device allows you to bypass these restrictions. Right now I have it plugged directly into my laptop, and I have been getting between 4 and 6 megs/sec download speed. I am very close to a tower, so this is probably the best speed you can expect. My only hiccup was that this device takes a larger sim card than the one I took out of my phone. There is probably an adapter available, but with a little trial and error I was able to position my tiny sim in the correct position such that it works.

Works easily out of the box. Might have to manually input the APN. For anyone that wants to use this on the interior of their machine or computer and doesnt get a signal (I have mine in a 4U server chassis and couldnt receive) you need an external antenna. I had asked on here but nobody could answer. However, I managed to purchase a couple and found one that worked. 8dB US Cellular Huawei UML397 E397 USB Modem External Antenna https://www.amazon.com/dp/B00VVWVS70/ref=cm_sw_r_cp_apa_xiQeAbJC88R1A

The device came locked and some instructions have been provided but I was absolutely unable to proceed to the unlock

Five stars. I inserted my at&t SIM card and plugged the USB end to my portable router TPLink 3020 to wirelessly share the 4G/3G connection to 9 devices successfully and running well. I am buying 2nd one of this product.

I was getting tired of carrying both my phones (personal and company) I made my personal my mobile dongle for my surface pro.

I bought this for use with Google Fi. I have a cell phone with them, and got the free Data Only Sim to use in this and it worked without any issues. Popped the sim in, let the required software install on my laptop, and I was streaming NBA games at LAX with no problem. Have yet to experience any issues with the device itself, maybe the only thing being reach/range, which is why it will receive 4 stars. I only mention this because I used it on an Amtrak train crossing the US, and in some spots my cell had service while this did not. However, its worth noting, it supports the attachment of an external antenna, which might have negated my issues.

Bueno

After reading all of the reviews, I figured Id give it a shot and glad I did. This LTE modem works with T-Mobile in the US. The process was very easy! 1) Call T-Mobile to add a data line and provide them with your SIM Card Number 2) In Windows 10, go to Network Settings, Cellular, Advanced Options and enter an Internet APN: type a profile name, I used T-Mobile, then enter the APN as epc.tmobile.com. Leave everything else as the default settings, apply the profile, then save. 3) Reboot and surf!

The device run as advertised. I run a speed test, download = 27Mbs and upload = 11Mbs. I used my iphone to run speed test, download - 50Mbs and upload = 10Mbs. This is Tmobile LTE. I am happy with the results.
