Seriallink Industrial 4G LTE Router 1xLan 1xWan Ports DIN LTE Wirelss Router Supported AT&T

Didnt work, half the instructions are in chinese and this is just another chinese scam. I tried for hours on end and the sim card port came DAMAGED which is unacceptable. I could barly get my sim card in. If you're good with tech and you know what you're doing go ahead but I myself couldnt figure it out.

On a hunch, i decided to sandbox a copy of each devices firmware for study. Initial examination its seemingly harmless, unit you get around to observing where these devices are routing your traffic.BGP and MPRLS Protocols will naturally make the shortest amount of hops possible for a packet to reach its destination. Not with seriallink devices.... no no. Magically my packets decided its a good idea to make a pit stop in Beijing on their way to arriving right back to my house. ALL OF THEM.They tried to cover this up with a few packing tricks and deceptive control files. Ill admit, had me fooled.Not sure what exactly the motive is... I dont usually jump to conclusions but condidering the servers are owned by front companies with ties to the DPRK unit equivalent to Americas NSA , id say these products are up to no good.
