The iPhone 12 and the iPhone 12 Pro will not be able to kick into 5G networks if you’re in dual SIM mode, according to an internal document that was posted on Reddit a few days back. MacRumors confirmed the authenticity of the document – it’s solely for Apple employee training – and that it obtained another internal Verizon slide containing good news. Apple intends to launch out a software update that will enable 5G even in dual SIM mode later in the year.
The company’s latest iPhone models can support a physical SIM and an eSIM at the same time, giving you the ability to have access to two networks simultaneously. However, the iPhone 12 will only be able to connect to 4G LTE at launch if you’re using two lines. The original training document reads:
“Does 5G work with Dual SIM?
When using two lines in Dual SIM mode, 5G data isn’t supported on either line and will fall back to 4G LTE. If customers are using eSIM only and are on a 5G supported carrier and service plan, they’ll have 5G access.”
The Verizon slide MacRumors obtained also says you’ll have to remove your physical SIM to access its 5G network with an eSIM. If the company truly is rolling out an update to change that within this year, then you probably won’t have to remove SIM cards or make do with a 4G connection for longer than a month or so.
