A connection to the remote computer could not be established

Hello guys,
today I bought sim card from our national mobile operator, with unlimited connection to the internet. I bough that because I wanted to insert this sim card to Huawei E3372 LTE Modem and so I would have access to the internet because of very slow download speed in college.

I recieved card, inserted it to USB modem, connect it to laptop and it automatically installed application "Mobile Partner". Everything seemed to be working fine until I click "connect". Everytime I did this, my only experience was to see "a connection to the remote computer could not be established". So I started to find solution.
I found some advises on operator official site, which were to change APN in application. So I did that, as so I did on my laptop. Nothing worked. Then I found on some site to type "netsh int ip reset reset.log" in commad prompt and then reboot my windows. Never worked. I was still recieving the same message from the application. I was so frustrated that I started to combine everything and downloading new drivers, windows updates, checking every corner of the internet to find solution but no advise solved my problem.

If anyone has some solution or only advise I would be very grateful. Thank you in forward and apologize my average english and technological amateurism. Have a great day everyone!
 
It would be nice if was that easy sometimes.

The sim is only 1 part of the equation. The end device must have the proper radios to talk to your ISP. You must be sure it is designed to work with your carrier. Unlocked does not mean it has the proper radios. This is very hard to find many times because it may have the same model number but have extra letters at the end of the part number.

Best to ask your ISP if that device is supported by them.

The next problem you many times have is even though the device will work many ISP require you to call and get them to activate it. They say this is to prevent the use of stolen devices but I suspect it is also to make it as much a hassle as possible to use device you did not buy from them.

Huawei E3372 is definitely supported by ISP because they have manual on their official site for this device. I bought this Modem after reading many reviews and everyone stated that the device is compatible with every operator in my country.

What is really going to make this fun is if you have to get your school IT involved. The token that my son's school insisted on installing into his computer in order to access network there played havok with getting on the internet here. I actually have his computer on it's own wireless network and part of a different workgroup. Bad mojo.
 


But WHICH e3372 did you buy there are many, I did not make the comment about the letters and numbers without actually researching this.
