Initially mobile phone are coming with single sim card slot later it's proceeds to dual sim card slot and now tri sim card slot but it is very difficult to manage and also it requires more battery to access all the networks connectivity but motorala has solved problem and very soon is to going to launch in india.
Whether we need to buy this iSIM to access four numbers in single handset?
No.You can use your existing network sim and there is a small wafer that is going to attach with it and this allows the cellphone user to access other three network number with your exisiting number.
iSIM Four Phone Numbers Need four IMEI (International Mobile Equipment Identity)?
No.Each iSIM comes with Four IMSI(Internation MObile Subscriber Identity) and each IMSI is unique and 15 digit number and that is going to provisioned with each network SIM and this IMSI is going to monitor by network operater.
I think this iSIM will be most popular in Asia because every person have more than 2 mobiles.
