There are many 4G/LTE routers in AliExpress, and I have dangerous tripped to buying unknown brand name of TianJie among them
I believe someone considered buying this router or not, yes, I was one of them, and now I can speak — nah, write this is just a “Piece of shit”.
Size is good to hold on a hand, compare with iPhone5.
Why a piece of shit?
At last to write why, This junk device totally not better than any Huawei LTE routers in similar price among 30 to 40 USD in Aliexpress, because worst web UI and never-works functions, unstable booting, only works with their batteries (not accepts same specified Galaxy S3 battery, it was going to failure while boot with compatible battery, never charges, never boots at all) and easily break
Battery not compatibles with Galaxy S3 even seller mentioned.
Specification ?
Supported frequencies
Yes, I’d just checked this table and believed I can use it for Worldwide until it delivered to me and past few days. I could see multiple times to device going failure to complete boot process, and it continuously repeats reset. When it starts to unlimited looping to boot failure, I can do anything to connect to device with Wi-Fi or RNDIS through USB. I need just press reset button on back side after pull of cover – It’s really annoying myself !
Multiple LTE frequencies may look great, yes I did too. But don’t be got deceived – this junk cannot fully operative until you ran out all LTE amount in a month.
What’s problem ?
First, this device is too weak, or wrong made of chassis, or wrong housing plastic body. I could find many narrow spaces going wider between front and side frame, and it was belonged to broken all screw bridges inside.

Broken inside screw bridges
I was needed to fix all broken bridges with UV bonding. Weak plastic material may a reason.
And poor internal-web UI, and useless functions like SD card sharing, or never works functions. Specially many lacks of network features like NAT, VPN and DDNS, or manual settings for DHCP – there’s nothing, nothing at all !
What SD slot existed for ?
Manufacturer has no web page, or service for customers. Only they are sales on AliExpress. No one can get feedback for these problems.
Performance
Specially, performance is not better than Huawei at all because this junk used MediaTek MT9735 processor with 32bit Android 6.0.
Maybe choice of Android 6.0 was good to make good services for user, but this junk seems never had plan to that. It must be a reason to make cheap device for router, and provided sample from MediaTek to spend out many stocks of MT6735 processors.
Conclusion
Buy Huawei E5573cs series !
I strongly recommend buy Huawei E5573cs series if you have plan to buy MF903 series. It is just an easy way to waste your money and time. Don’t waste your any belongings.
Do not buy this junk.
