I have huawei e1550 3g modem and it is locked to network operator "Idea" while using through windows(which I don't like).

Is it possible to use another network operator on this modem on ubuntu or Is it also locked for ubuntu?

I am able to access internet using it via the default network operator, but not by another operator.Is it my fault or Its also locked on ubuntu? But I have entered the correct settings.

While checking for network locks using ixconn I found the following:-

* Test for netlock           

Manufacturer: huawei    
Model: E1550    
Revision: 11.608.13.02.00    
IMEI: 354638041122655    
+GCAP: +CGSM,+FCLASS,+DS

OK    
--- No network locks recognized. ---

and it also shows the n/w operators availabe on doing gprs n/w analysis

on doing AT^CARDLOCK? i got 3,0,0 which mean that this can't be unlocked

on connecting to internet it keeps searching network and never connects to internet(except default operator)

I need explanation wether if its locked for ubuntu or not? and if not whats the problem?

3G sticks are by and large designed only to be used on a particular network operator. When you got it from Idea, only connections with Idea 3G data plan enabled will work. It is not a Ubuntu thing. The problem is that Ubuntu might detect the card, but configuring it for use is a different matter.

  • Nope. On an Idea 3g, you can only use a Idea sim, unless the Stick and card are locked somehow.

I think the stick is locked. It is easily possible to unlock the stick with the software for Windows. I have the same which was locked and is now unlocked. But i don't know if it's illegal to describe the way here so it's the best to search for it on google.
