The coverage might not be good enough for 4G where the router is placed. Try a different place.

Is only a green LED on and not a blue one?

How did you unlock the router?

Are you using it on the same exact provider or did you attempt to move it to a different provider.

Like most LTE devices just unlocking them does not mean they work on all vendors. They must function on the correct radio channels. Do you know which band the ISP you are trying to connect to runs on.

From a quick search on that part number there are actually 5 sub models. There should be a letter and numbers after the main router number. This represent the radio bands it will function on.

There are actually a couple more models than this but this is one list I found.

You will see it support only band 38 and 40 using TDD.

Huawei B593 4G LTE CPE Industrial Wireless WiFi Router Speci:
Frequence:
HUAWEI B593u-12: LTE FDD Band 1/3/7/8/20 (800/900/1800/2100/2600MHz) without telephone port
HUAWEI B593s-22: LTE FDD Band 1/3/7/8/20 (800/900/1800/2100/2600MHz) and TDD Band 38 (2600MHz), LTE Category 4 CPE (Speed up to 150Mbps)

2G: EDGE/GPRS/GSM 850/900/1800/1900 MHz

I will assume you live in europe because these bands are not used many other places. You can look through this table and see the ISP and countries that support these bands.

thanks,, do you know unlock routers? using linux?

Unlock is about which ISP you can connect it to not what radio band it runs on. If 2 different ISP use the same radio bands you can activate it on either. A locked router would only let you run a single ISP even if others used the same radio bands.

You can not change the radio bands it functions on. That is why there are different model numbers. This is something that is set at the factory when the device is manufactured.

This is sorta like CDMA vs GSM phones in the USA. You can unlock say a verison phone but since it uses CDMA for voice you can not make it function on ATT who uses GSM
