Dual SIM dual standby is a very familiar mobile phone industry term, refers to the mobile phone can be inserted into two mobile phone cards, and can be standby at the same time, as early as ten years ago, there was a mobile phone on the market that supports dual SIM dual standby.
The real dual CARD dual standby function is the development of the Chinese market, Chinese consumers have a high demand for dual numbers, one number is public, the other number is used privately, only need to carry a mobile phone, you can separate public and private affairs.
With the rise of domestic mobile phone manufacturers, dual SIM dual standby has become a very mature solution, and now almost all newly launched mobile phones have supported this technology.
Especially a few years ago, many domestic manufacturers even dual card dual standby as a selling point of publicity, compared to the world's leading Apple mobile phone is indifferent to dual card dual standby technology, in the early years Ago, Android manufacturers made the dual card dual standby function into the standard of mobile phones, Apple always adhere to single card single standby.
However, for the Sake of the Chinese market, Apple still chose to compromise, in 2018 Apple launched the iPhone XR and iPhone XS Max, is the first mobile phone to support dual SIM dual standby function, but only the Chinese version is equipped with two physical card slots, that is, Apple has launched a model that supports physical dual card dual standby for Chinese users.
In fact, the subsequent iPhone also supports dual cards in overseas markets, but basically adopts the dual card of eSIM card + physical SIM card.
There is such a difference because Chinese mainland does not support the iPhone to use the eSIM card, only the cellular version of the Apple Watch supports, so Apple can only make a different design for Chinese users.
After the iPhone XR and iPhone XS Max, each generation of products launched by Apple has added dual SIM dual standby, including the iPhone 11 series support dual card dual standby, and the iPhone 12 series only iPhone 12 mini is a single card single standby.
The same is true of the iPhone 13 series released by Apple last year, only the iPhone 13 mini is a single card single standby, and the other three versions are dual SIM dual standby.
Then there is Apple's latest release of the iPhone SE3 does not support dual CARD dual standby, after all, the appearance is the design of the shell iPhone 8, there is no reason to add dual card dual standby function, it is not surprising that it is not supported.
From the product point of view, why the iPhone 12 mini and iPhone 13 mini do not support dual SIM dual standby, the author believes that there are two reasons.
One is that the price of the mini version is relatively cheap, so the profit is not as high as other versions, Apple hopes that consumers choose more expensive models, only choose the expensive version to be able to use dual SIM dual standby.
The other is that the mini version of the battery is relatively small, the battery life itself is relatively poor, if you support dual CARD dual standby, it will inevitably further reduce the endurance of the mobile phone.
Finally, to summarize, from the perspective of the models on Apple's official website, the models that support dual SIM include iPhone 11, iPhone 12, iPhone 13, iPhone 13 Pro/Pro Max.
There are also several models that do not support dual SIM dual standby, namely the iPhone 12 mini, the iPhone 13 mini and the iPhone SE, if you want an iPhone that supports dual SIM dual standby, then don't consider these models.
