iPhone 12 Dual SIM 5G Mode to be Enabled Later via Software Update

Citing an internal training document for Apple employees, a report by MacRumors is claiming that 5G data will initially not be supported on iPhone 12 models in Dual SIM mode. The internal Apple document, which was originally uploaded on Reddit, is said to have been verified as authentic.

Here’s what the 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.

However, an internal Verizon slide obtained by MacRumors shows that Apple plans to enable 5G support in Dual SIM mode with a software update later this year.

In the meantime, Verizon says that eSIM customers must remove the physical SIM from their iPhone 12 or iPhone 12 Pro to access its 5G network.

5G is automatically enabled on iPhone 12 and iPhone 12 Pro models, as long as users have chosen a supported wireless carrier that offers a 5G network. To access 5G while roaming in other countries, Apple’s document says that customers can purchase a local SIM card or eSIM plan and use it as a single line with 5G where available.

Apple kicked off pre-orders for two of its iPhone 12 models last Friday in Canada. You can check out the full iPhone 12 price list and pre-order dates here.
