Dual-SIM card capability is one of the most important upgrades of the new iPhone models released this year. For the first time, we can use two cellular plans on the same iPhone. This feature is very helpful for people who are using two numbers – one for business and one for family/friends, who want to add a local number when traveling abroad, or when you want to separate voice and data plans.
Although all iPhone models in the world support dual SIM, the bad news is that most have just one physical SIM card slot, the other one is an eSIM (or digital SIM) which is embedded in the iPhone itself.
Most people won’t be able to benefit from eSIM since it is available in just about 10 countries at the moment; Apart from the US and UK, some other countries supporting the eSIM technology include Austria, Canada, Croatia, the Czech Republic, Germany, Hungary, India, and Spain.
Obviously, most people will want to own the version supporting dual-SIM cards instead. With this version, we do not only have better flexibility but we can also use the function immediately without waiting for the eSIM software update. Even in the US, just a few major carriers like T-Mobile, Verizon, and AT&T are offering eSIM support; Therefore, consumers are also looking for the other version to use dual-SIM cards without any restriction. So, how can we buy that new iPhone version?
Fortunately, Apple releases a version for China, Macau, and Hong Kong. This version has a SIM card tray that allows us to place two nano-SIM cards at the same time, as illustrated below.
Notice that just the iPhone XS Max and iPhone XR have the capability. The new iPhone XS doesn’t support physical dual-SIM cards.
The two major carriers in China, China Telecom and China Mobile, support eSIM in a few cities but it’s not widely available yet; So, the regional version with physical SIM cards is reasonable. The model numbers or the iPhone XS Max and XR are A2104 and A2108 respectively. I’d highly recommend you to buy the version imported from Hong Kong since it uses the same global software as in the US, so you can use Apple Pay, Facetime and other features without any problem. At the moment, Facetime Audio is still not supported in China.
