hello guys,
i have bought this modem HUawei E 153u-2.i have been trying to unlock it A lot with no hope.it has been counter blocked,the modem currently use only one network,which is Airtell but i want to use other networks,since this has become much expensive
the thing is i tried to use the huawei code calculator,but it is not working,since i tried to put different GSM line but it does not prompt me to put the unlock code.
Anybody who knows,kindly please help...

regards
