Huawei mobile internet stick(Hlink E3131) using same named file, while building internet connection to your computer.
It can use processor time intermittently even when the mobile device is not present on the system.

In my case mbbservice slowed down the internet connection giving problem with the sound card. For instance was Skype working badly and got interrupted repeatedly. Sound dropped even while watching YouTube. Removing mobile Broadband HL Service solved the problem. Momentarily I have a poor Internet connection. With better bandwidth this program may not cause any problem.

I don't think it is dangerous, but it used considerable resources with my customised Win 7 installation. I disabled it in Windows Services. The drivers still load, and I can access the settings by going to the Hlink page.

Best practices for resolving mbbservice issues

A clean and tidy computer is the key requirement for avoiding problems with mbbservice. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
