Hello,

EM7455 provides dual sim support. Here, would like to know is it dual stand by or simultaneous operation is possible?

Another query: is it possible to use 2 different carrier sim cards? One from AT&T and another from Verizone? Or both sim shall be from same carrier?

Regards,  
Pavan

As per my understanding, even though two slots are there only one slot will be active and monitored at a given time.  
You can use different carrier sim card. for that you have to download both carrier image. you can contact your distributor for this 🙂
