Issues with using Huawei Model E1550 with Mac OSX 10.9

Use the following guide, if you are having problems using Huawei HSDPA dongle in OSX 10.9 Mavericks.

Download Mobile Partner for Mac OSX using the link below: (File name: MOBILE_CONNECT.ISO)

Double click on the MOBILE_CONNECT.ISO, and installation process will start. (P.S. Mac OS X supports ISO files natively without the need for any third-party software.)

Complete the installation process. A detailed step by step guide can be found here:

Now if you plug in the USB modem and try to connect using Mobile Partner, you will get the following error and program will crash:
Connection Terminated!

To resolve that, follow the steps given below:

Open the terminal
Type the following command:
 cd /etc/ppp

Point-to-Point Protocol (PPP) is a method of connecting a computer to the Internet. Working in the data link layer of the OSI model, PPP sends the computer's TCP/IP packets to a server that puts them onto the Internet.

you are inside the ppp folder now. type ls -l command. you should see the file named "options". Make sure the user has the required rights to edit the file. If not, use the following command to grant rights. (you need to provide admin credentials)
sudo chown options
Then edit the file using the following command:
vi options

go to 'insert' mode and type the following in that file:

+pap = Force PAP authentication (This immediately connects an incoming call to pppd, and then uses PAP (Password Authentication Protocol) to authenticate the client.)

Then click esc and save the file using :wq.

Restart the OS.

Then try again to connect using Mobile Partner.
