@ Animesh, @ Devil,
If you are on Karmic, Please check this LP #461096 for more details. I
think it's problem with ModemManager.
@ Devil,
Here is the line which causing the issue.

Jan 1 07:41:04 devil NetworkManager: <WARN> stage1_prepare_done(): CDMA modem
connection failed: No service
---
If you are In Lucid Lynx Beta 1, You will get the same problem while
connecting Huawei EC1260 with Reliance NetConnect Broadband+ service.
ModemManager checks for SID / Class / Band. If it will not get those
value it will give "No Service" error, as given above. In 0.3
ModemManager allows SID=0 in some cases. But, below code is putting
SID=9999, because of No Band / Class by provider. Please comment below
code in mm-generic-cdma.c, rebuild the package, Now RelianceNetConnect
Broadband+ service will work Huawei EC 1260 Modem, it's also true for
other modems, but not tested, still investigating the issue, but this
hacks works for me.
---
/* Return 'no service' if none of the elements of the +CSS response
* indicate that the modem has service. Note that this allows SID 0
* when at least one of the other elements indicates service.
* Normally we'd treat SID 0 as 'no service' but some modems
* (Sierra 5725) sometimes return SID 0 even when registered.
*/
//if (sid == 0 && !class_ok && !band_ok)
// sid = 99999;
