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

Works perfect. T mobile on plus 4G lte plan sim card (you will need the largest sim card, T Mobil will give you a free kit at any shop) Works perfectly on windows 10. Installed the driver with the autorun when plugged in usb port. Restarted my computer and bam mobile internet! Attached picture for speed.

Works with a Google Project Fi data-only sim. Had some issues with getting the sim card to work reliably, occasionally getting SIM errors, hence 4 stars.

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.

Buy this product for about a month to use with my internet service provider (Viva) in Dominican Republic. The idea was to share the data plan of my SIM card with several computers, via a TP-Link TL-MR3020 router that also buy for such purposes, and the device has not worked for me with the router or the computer, which also I tried it to see if it only worked with the software for PC that brings the USB. I would like you to give me an idea or explanation about this case.

Bought this for use in China and in Hong Kong (China Mobile and Unicom). Both sim cards did not work. Device would not activate. Not sure if it is all hardware but being this is an unlocked device, I am assuming it would work with any GSM sim card. Couldnt test it on TMobile (but reviewers say it works) while in the USA since this item requires a full sized sim card and I did not have a way to put my nano sim in it for testing before coming back to China. who uses those nowadays? The other thing shoppers should note, the spring inside the sim card housing is too strong. I needed more than a fingernail to push the sim in and get it locked.

2019 Still works and simple plug and install lil software from device it self on Windows 10 Atleast

Words fine with T-Mobile SIM card

Using this as a secondary connection for my Asus router with an extra data sim card I had laying around. It works fantastic! Ive set up my Asus router to use the Sim card dongle as a fail-safe when my dsl goes out and it has worked flawlessly the three times our DSL has gone out, switches right over to the dongle and internet is right back up over 4g LTE in a minute or so. As soon as the DSL comes back this dongle goes into standby mode and just waits patiently until its called on again. Im using a T-mobile sim card in this dongle that has unlimited data. Its an extra we have on our family plan and its now being put to good use.

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.

This device does NOT work with Tmobile sims. I have an older Rocket 1 Sim, a brand new prepaid kit sim, and two sims from older ZTE hotspots. The device itself is blacklisted from the tmobile network. I get a page redirect to Tmobile that says Your data plan does not work on this device. Click *here* to sign up for a new data plan. Clicking the link takes me to Were sorry, we are not able to help you with a plan change here. Please check my.tmobile.com or call customer care to complete this service charge. Additionally, the cricket connector software (which works great by the way) opens a Cricket purchase page. Which does not resolve since the device is not on a network. I re-enabled my Desktop connection to diagnose. Worked on it for an hour or so. All other Sims with all other devices brought me to the tmobile page to reactivate or pay more. They want your money for sim data. Not for this device. I didnt even bother calling in. They know the score, its an obvious blacklist. This device may work with other carriers sims - but not tmobile. Additionally, the IMEI pasted into Crickets BYOB check showed it was NOT compatible. There was a number missing. Not going to play guessing games on this one. Will return for true Tmobile rocket usb device. *edit* Changing from a 2 star to a 4 star. I had to learn what an unlocked modem actually meant. This device is blocked from Tmobile itself, but subcarriers like Simple Mobile work just fine. I am doing some testing with carriers in my Florida market. Simple Mobile does work. 9D 5.5U 9/24/2017 *edit again* Tested an H20 Sim. Buying worked even better than Simple. ATT network instead of Tmobile. Put on the $10 plan which is supposed to not have data, but it worked. 7D 1.5U *edit 9/28/17* Got my Lyca Mobile sim in the mail. Activation required a handset, so I had to flip them to run * codes. Then activate the sim on their website before I could even get to plan purchase. $19 was the min and that was for 100 MB data. Plans did not seem comparable to others on the market, so I mothballed the sim. Changed review to five stars. I love unlocked USB modems! May play around with other sims and data plans but we sort of already have a North America winner in ATT and TMOB with H2O and Simple. Simple has a Walmart partnership and you can grab top-up cards from anywhere, as well as online, easily.
