Now its time to launch multiple SIM cards with same MSISDN (Mobile no.) as handset operating multiple SIM cards has been an exhausted idea due to battery back up shortage. One in smartphone and another in simple phone. This can happen with prioritization concept i.e. the call should latch on the switched on handset if another is switched off and on either of handsets if both are switched on subject to condition of prioritized handset in such circumstances.
