How to switch the mobile network in program?
<p>Peace upon you ,
I searched more  but didn't get the answer. Currently I have 2 mobile
networks for my mobile say they are A and B.
Is there a way to automatically detect the mobile networks if there
are A and B then choose A? Or just simplely choose A no matter whether
there is B availible? I want to search for gsm networks operators
available and select the preferred one.</p>

<p>Thanks.</p>
