Phones with two SIM cards make life much easier for people who want to separate their work and personal lives. There are three types of phones for two SIM cards, each with its own characteristics.
Doubtful option
The simplest type of dual SIM phones is Dual SIM. In such phones, only one card can be active, switching to another SIM card is carried out through the "Settings" menu, which is not very convenient. Moreover, the loading of the second SIM card takes a long time. Of course, no one can call you on an inactive SIM card. Phones with this kind of technology are pretty hard to come by these days. Be sure to check if the chosen phone belongs to this type of device, so as not to be disappointed after the purchase. The only advantage of such a phone is the extremely low price.
Perfect option
The second type of devices includes Dual SIM Stand-By. This technology keeps both SIM cards active in terms of standby mode. During a call to one of the cards, the second is disabled, but after the end of the call it returns to normal operation. Accordingly, if you spoke on one SIM card, and at this time someone tried to call you on the second, after the call is completed, messages about missed calls will come to the second number. Phones of this type are more expensive. Usually the prices for such phones are kept at an average level. In fact, this is the best purchase option.
Modern version
The third type of devices with two SIM cards is the Dual SIM Active. This is a relatively new technology that is just starting to spread. It is good in that both SIM cards remain active even while talking on one of them. If during a call to the first SIM card you receive an incoming call to the second, you can put the conversation on hold and answer the second call. This feature is especially appreciated by people whose work depends on the phone. This type of phone runs out of battery faster, since the charge is consumed by two active communication modules. Increased power consumption tops the list of cons. In second place is the increased radiation level due to the same two active modules. It should also be noted that devices of this type are still sold in small quantities and are quite expensive. So, if your life does not depend on how quickly you can answer a call, you can safely choose the previous type of phone.
To find out what type of phone the phone belongs to, just pay attention to the markings on its packaging.
