iOS 12 code hints at dual-SIM support for 2018 iPhones

One of the biggest expected changes coming to the 2018 iPhone lineup is dual-SIM support. Numerous reports have discussed this possibility, but now there’s proof coming directly from Apple itself.

Apple has just released the iOS 12 developer beta 5 to the public. 9to5Mac’s Guilherme Rambo dug through the software and found pretty compelling evidence for a dual-SIM iPhone. First, the system in charge of diagnostic reports now has references to “second SIM status and a “second SIM tray status.”

Second, a separate component talks about a “dual sim device.” It’s easy to infer that iOS is being reworked to support a pair of SIM cards as we get closer to the 2018 iPhone lineup’s September launch. What’s not clear is which model will gain support for the feature.

Which iPhone Will Get Dual-SIM Support?

Ideally, all 3 upcoming iPhones should get dual-SIM support. However, rumors so far have suggested only 2 out of 3 will gain the functionality – the 6.1-inch LCD iPhone 9 and 6.5-inch OLED iPhone X Plus. The 5.8-inch OLED iPhone X (2018) is apparently going to stay as it is.

Another point of uncertainty is how Apple is going to implement this. A recent report claimed that only Chinese iPhones will have a physical SIM card tray with 2 slots, while the rest of the world will get a single slot. The dual-SIM feature for the latter will be made possible via a virtual Apple SIM.

Apple SIMs have been around since 2014, but are currently limited to iPads. It’s available in 180 countries at the moment, with China being a notable exception. That may be why the country might get an additional SIM card slot.

It should be noted that Apple doesn’t provide the network for its embedded SIM. It allows users to choose between local carriers instead, a useful feature for people who travel often. Having an extra SIM handy will also be a boon to folks who have a separate number for work.
