When buying a dual SIM mobile phone there is one feature that creates a lot of confusion among the customers. It is important to know what Dual Active and Dual Standby really means.

You are buying a dual SIM phone and its specifications say it supports dual Standby, do you really know what it is or are you just happy that you can use 2 SIM on a single phone. In most cases customers get disappointed because they never understood the feature.

Dual Standby Phone

Dual + Standby, this means the phone supports dual SIM but in Standby mode. In simple words when none of the SIM are used then both the SIM’s are active but when you are using a particular SIM the other SIM becomes inactive.

Another issue with dual standby phones that support 3G is that, when the 3G / 2G network is used the other SIM becomes inactive. Usually you will not notice this issue with normal usage, but try downloading a big file or watch a streaming YouTube video, the other SIM will be unreachable.

In dual standby if a person is using SIM 1 and a caller is on SIM 2, he/she will receive a reply “not reachable, try again later”.

Many of the dual SIM users usually talk more on one particular SIM and the other SIM is basically for their personal use – not so important, they don’t really have any issues with this mode. If you want both the SIM’s active at all times then this feature is not for you.

Dual Active phone

As the same suggest, its Dual phone with active mode which means both the SIM’s (SIM 1 and SIM2) are active all the time. Dual active is relatively easier to understand. Use SIM 1 or SIM 2 for voice calls or net surfing the other SIM is always active you can still receive calls on the other SIM and even switch calls. For example, you can keep the caller on SIM 1 on hold and talk to the other user on SIM 2.

The Dual Standby phones use a single transceiver which at a given time can server only one SIM, whereas most dual Active phones come with dual transceiver, one for each SIM.

Do check before you buy the dual active phone because even when the manufacture says that it is dual active it still works like a dual standby.

Thank for d info

Thanks, Good info... but it means we cannot be sure before buying a phone that its dual active or not - as you mentioned that some manufacturers don't use this term appropriately...
