● iPhone interior design "Land"
The reason the iPhone has not supported dual SIMs for a long time is because of its internal layout. I believe many users are puzzled: why the overall size of the fuselage similar, Andrews machines have dual card support, and the iPhone can not support it?
Take iPhone X for example, if we look at the iPhone X real machine dismantling map, perhaps you can know a little bit.
If compared with Andrews design, iPhone X's internal design is undoubtedly more compact, motherboards, batteries, sensors, etc. filled the entire body, if in accordance with the design of Android devices to do so, iPhone X battery capacity can be further Low, making the phone's life can not be guaranteed. Tradeoffs, give up dual-card is undoubtedly a better choice.
In fact, in order to improve the utilization of the fuselage, Apple has taken the lead in reducing the space occupied by the SIM card in the fuselage twice. Has brought the phone SIM card into the Micro-SIM card and Nano-SIM era. Such an apple, it is hard to imagine it will double the SIM card to increase the proportion of space.
● Foreign markets, "dual-card" is not the mainstream
More important reason is: Unlike many domestic mobile phone manufacturers, iPhone based on the global market, but in addition to China and other parts of the Indian market, dual card still without losing the mainstream.
Taking the U.S. market as an example, foreign users often make purchases through contracts with operators. Dual-SIM will undoubtedly damage the interests of operators, making the majority of mobile phones sold in the United States a single card.
Moreover, the U.S. market does not have roaming charges and does not need to consider the issue of attribution. But also to achieve number portability network, do not have to hold long SIM card because you want to change packages and other issues.
● Will the iPhone support dual SIM in the future?
I think the answer is yes, the turning point is the eSIM in the picture above.
This fall's new Apple conference, iPhone X attracted the eyes of the majority, which also makes Apple's Apple Watch Series 3 dimmed a lot of light. The most noteworthy point of this product is to provide a cellular network version for the election.
Although this product's cellular network has so far failed to function properly, it undoubtedly sent a positive signal: Apple has been negotiating with domestic carriers on the issue of using eSIM, that is to say, in the division of interests of operators to solve the problem After the new iPhone to join eSIM is not impossible.
Moreover, in recent years eSIM has begun to be applied in many areas: including some children's watches, Xiaomi Millet notebook released this year, Air 4G version.
In my opinion, if the future of the Apple iPhone to join the eSIM function, to achieve dual-card function is not a problem (of course, there may be eSIM + SIM card transition period).
to sum up:
In fact, the operation mechanism of domestic operators is also gradually changing in the past two years. From the initial abolition of roaming charges to the recent transfer of old users to Internet packages and the portability of numbers by 2020, the future domestic users' The demand for SIM cards may also face tremendous changes. By that time, iPhone support does not support dual card may no longer be important.
