The HUAWEI Mobile Partner software is written in Java and seems to be mandatory to connect with HUAWEI’s mobile devices, but I think it is really annoying to always keep this heavyweight piece of software open while accessing the Internet.
The device will also appear in Apple’s built-in Network Manager, once the drivers are installed. But unless the PIN is disabled, trying to use the Network Manager (System Preferences > Network) will fail. In a next step, I tried to open Mobile Partner for entering the PIN, but then closing it without connection initiation. After entering the PIN, the connection via the Network Manager seemed to work fine! So we need a solution to enter the PIN without using the Mobile Partner software.
Eventually, I found the following solution at hints.macworld.com. It requires that drivers are already installed, e.g. by using the installers from HUAWEI. It works with my HUAWEI Mobile Connect E160 card (o2 Surf Stick).
An alternative to this solution is to disable the PIN completely, but be sure if somebody steals your surf stick or your SIM card, he will be able to use your Internet connection and possibly do illegal stuff.
