No doubt the technology is the best in case of an IPhone but Indians are finding it difficult to make a switch as IPhone comes with only one sim and we as Indians have a habit of keeping backup. This backup can be in form of savings for our retirement or can be a backup for our mobile number and it is rare to find an Indian with a single sim these days as mobile technology has really caught with India in a big way.
Now life has been made easier courtesy dual sim adapters by virtue of which you can easily to switch 2 SIM cards without turning off the phone. Moreover one need not require to cut sim card as IPhone requires a micro sim. All the more one need not worry about the data loss while switching 2 numbers or turning on/off the phone. Such adapters are available for $5 on the net for online purchase.
It is worthwhile to mention here that even 3 sim adaptors come for IPhone; but go for it only if you really require it. Check its local version in any Indian store and understand its functionality before going in for a purchase.
