After days of google search, I was finally able to access the internet through my old ZTE MF626 USB modem (branded as Globe Visibility way back then), thanks to these three blog posts:
The good news is you don’t need wvdial with this setup. Here’s the step-by-step process:
USB_ModeSwitch is (surprise!) a mode switching tool for controlling “flip flop” (multiple device) USB gear.
Several new USB devices (especially high-speed wireless WAN stuff, there seems to be a chipset from Qualcomm offering that feature) have their MS Windows drivers onboard; when plugged in for the first time they act like a flash storage and start installing the driver from there.
After that (and on every consecutive plugging) this driver switches the mode internally, the storage device vanishes (in most cases), and a new device (like a USB modem) shows up. The WWAN gear maker Option calls that feature “ZeroCD (TM)”.
In short, we want our Globe Tattoo USB drive (or any carrier device for that matter) to act as a modem, not as a flash drive that your favorite distro would mount automatically.
To do that, we need to follow pinoyTeacher’s instruction:
a) insert your Tattoo USB drive
b) Terminal -> lsusb
Take note of the vendor ID (it’s 19d2 for ZTE, 12d1 for Huawei, etc).
c) Terminal -> sudo apt-get install usb-modeswitch
d) Terminal -> sudo usb_modeswitch -H 19d2:1446 -v 19d2 -p 1446 -R -V 19d2 -P 1001
Note: You would know that usb_modeswitch works when you don’t see your ZTE Tattoo USB drive being mounted automatically after inserting it. This is in contrast with Huawei E1552 USB stick which was auto-mounted by Linux Mint 9 (indicated by the Globe Tattoo icon on the desktop).
2. NetworkManager is all you need
e) From the system tray, right-click NetworkManager
NetworkManager -> Edit Connections… -> Mobile Broadband tab -> Add
Choose your mobile broadband device -> Forward -> Country Philippines -> Provider Globe Telecom ->
Select your plan (My plan is not listed...), APN (enter http.globe.com.ph) -> Apply
Make sure to follow these settings:
Then, click Apply. I edited the name of this setting as Globe Tattoo. Wait for a few seconds, then click the NetworkManager icon. You should be able to see your Globe Tattoo in the menu, so just click it.
Tip: If you are on postpaid, the APN is internet.globe.com.ph
