I assume you are using a Tata Indicom Photon EVDO connection
They use a ZTE AC8710 USB modem device..The apple WWAN drivers work prefectly for this, but the default driver list does not include the vendor and device ID for this particular device, so the system is unable to recognize the ZTE device as a WWAN device
There are 2 ways to get it working, the first (which is what I used, and works like a charm) is via manually adding your hardware IDs to the WWAN support plist files
- get your hardware ID (PID/VID available via system profiler under USB as ZTE modem. e.g. Product ID: 4567 Vendor ID: 1ab2)
-edit the WWAN support plist files viz /System/Library/Extensions/IOSerialFamily.kext/Contents/PlugIns/AppleWWANSuppor t1.kext/Contents and
/System/Library/Extensions/IOSerialFamily.kext/Contents/PlugIns/AppleWWANSupport .kext/Contents
- you will see multiple devices with their respective vendor IDs and product IDs listed there, just add another similar new line (or edit an existing line) with the vendor ID as 0x1ab2 and product ID as 0x4567
(notice the leading 0x, and make sure you replace the example IDs with the actuals)
- Save, restart and voila, your device will show up under network as a WWAN device
- Use the UID/pw to connect 🙂
The second method is to try the Reliance Comm drivers for the AC8710

I cannot vouch for the second method method, as I havent tried it myself
