Apple today seeded the first beta of iOS 14.5 to developers for testing, and a key new feature is global support for 5G in Dual-SIM mode on iPhone 12 models, as noted by Rene Ritchie. This functionality was previously only available in mainland China.

iPhone 12 models are equipped with both a physical SIM slot and a digital eSIM, allowing for a feature known as dual SIM, dual standby. This means you can have two lines of service on one iPhone, which is useful for purchasing data-only plans while traveling abroad or having personal and business lines on a single iPhone. Until now, Dual-SIM mode was limited to LTE, but iOS 14.5 introduces support for faster 5G on both lines.

Apple has previously said that iOS 14.5 will be released in the early spring, so the software update will likely become available in late March at the earliest. A public beta will likely be released within the next day or so.

An internal Verizon presentation obtained by MacRumors had indicated that Apple planned to enable 5G in Dual-SIM mode by the end of 2020, so the functionality is arriving a few months later than expected.

good for you. obviously i am the negative guy, but the first thing i did when i migrated to the 12pro was to switch off 5G. i use my phone a lot and i have great battery life now. i absolutely see no benefit for 5G, because the transmission speeds are pretty much on par what i get on LTE. and honestly, i'm not the one who flexes with speediest screenshots.

You mean 5G, but I read it as 4Gs. Europe is still struggling to get 5G or whatever it is they like to call it. I think of it as 4G yet.

Very few companies support eSIM in the world ands in contract only. I don't know why Apple call this Dual- SIM.
Dual-SIM means you can put 2 SIM cards into one phone like HUAWEI , XIAOMI has real Dual-SIM support.

The eSIM is a real SIM just like the one made of plastic so its called dual SIM because it can use two at once. Why would they add two slots when really then plan soon to have none.

OMG!!! Apple makes my day today. I love new features. Way to go!

Samsung is much more behind now without even support of eSIM in the USA :)

BTW: I'm far from being an Apple fan

Prepaid cards are plastic. To have none will take 5 years or more.

What's the benefit of eSim if they can provide dual physical SIM cards in a different market? What's the downside of using two physical SIM cards?

Cool to see this, I thought the restriction preventing having two 5G SIM cards was due to limitations with the X55 modem. Guess I was wrong.

For all the ports Apple has removed over the years, getting rid of the physical SIM slot would be one I am happy with. Both my US and European networks support eSIM. I'd like to see the Apple Watch support dual eSIM.

Dual Sim works great!

I have my primary physical Sim as a T-Mobile Sim and the eSIM on Verizon so I’ll now be able to get 5G on Verizon on the eSIM! Awesome!
Congratulations. When I switched my T-Struggle SIM to eSIM, T-Struggle locked my phone somehow so I could no longer use physical sim from another carrier. I was only in the US on vacation and had previously been switching SIMs between Japan and US, with my Japanese carrier able to utilize an eSIM.
