The iPhone 12 and the iPhone 12 Pro will not be able to access 5G networks if you’re in dual SIM mode, according internal document that was posted on Reddit a few days ago. MacRumors says it was able to confirm the document’s authenticity — it’s apparently for Apple employee training — and that it obtained another internal Verizon slide containing good news. Apple reportedly plans to roll out a software update that will enable 5G even in dual SIM mode later this year.
