I am writing how to make the modem simyo provides (the commonplace Huawei E220) on MacOSX first, because apparently the PIN has to be deactivated for the modem to work in Linux. I have to admit that in MacOSX installation was a breeze.
Start MacOS, then plug the USB modem. A window will open automatically, with two objects inside: "MobileConnect" and "User Manual". The former is the installer binary, and the latter is a folder with the manuals in PDF format (for me, they were in English and Spanish).
Clicking on the "MobileConnect" icon the installer will start, and after being asked to accept an EULA, then introduce the admin password, then choosing a location for placing the files (actually just a hard disk, not a concrete dir), the installer does its thing.
After that, we only need to configure a connection in the "Mobile Connect" window that opens automatically after installation. For that, click on "Setting..." and create a new profile. If you read the manual (see above), it is easy to fill in the blanks. In short:
- Profile name: whatever you want
- Access Point Name: this is the APN value that simyo tells you in some paper (gprs-service.com)
- Telephone number: *99#
- Account name: irrelevant
- Password: irrelevant
Save the above, then choose the profile you just created in the drop-down list in "Profile name", then hit the "Connect" button. If after saying "Dialing up, please wait", it tells you "Connection succesfull!", then everything is fine!
Apparently using the modem under Linux requires that the PIN is deactivated. Doing that under MacOSX is easy: when the "Mobile Connect" window is active, go to the "Manage PIN" drop-down menu in the top bar. There you can find "Activate", "Deactivate" and "Modify". Self-explanatory, ain't it?
