Apple granted patent for dual-SIM technology

Apple granted patent for dual-SIM technology
Recently we came across some rumors that Apple might be looking to hit the Chinese market with a dual-SIM version of the iPhone 8. We've seen such rumors prior to the launch of the iPhone 7 too, but they proved to be untrue. This is why we dismissed the new speculations entirely, without looking to much into them.

We might have been wrong to do so, though, as the database of the United States Patent and Trademark Office (USPTO) now contains a patent, granted to Apple, for a dual-SIM technology with two separate antennas.

The patent details the technology used to work with two SIM cards, and how to determine the priority between them. According to the description, the card that's actively used for a call will have the priority over the one that's used for data at the same time, which is perfectly normal. We don't want our calls cut short, just so we can receive a Candy Crush invite.

Some embodiments, detailed in the description, support LTE networks, which is to be expected for a flagship device, so having two SIMs won't compromise connectivity options at all.

It is important to note that this is merely a patent and it doesn't confirm any dual-SIM iPhone rumors. Apple may or may not use this technology in future devices, but after this one, we'll keep our eyes open for more info on a dual-SIM iPhone.

I have a feeling they'll act as if they came up with it and call it revolutionary.

This is a good idea... especially if they want to increase their market share in India and China

whats so special about apple's dual sim vs that thas has been in existence even before the first iphone or even today's dual sim technology that may have evolvedfrom then

Looks like US patent system is seriously flawed..

iSheep will gladly fork out the extra $300 Apple will charge for it whilst claiming it's the first and only dual-sim, dual-lte, dual-active phone on the planet. Apple will call the "innovative" technology iTalk and sue Google for using the name Gtalk back in the day. Then turn around and sue everyone else for violating their "groundbreaking" patent. iPhonearena will give it a 13 out of 10 because Apple's implementation is far superior to anyone else's. Mxy and Alik will become apoplectic defending Apple and blame Samsung for everything including global warming. Does that sound about right? Lol

Haven't about a million low end phones been implementing this tech for the past 5 years?

Well, it's Apple... So maybe Apple's version of dual-SIM tech is unique, that's why they applied for this patent.

Another innovation by Apple. Great, and US -patent system is great too. why they recieve patent for something so common? This patent is bound to create controversies. Im sure there are many smartphones in market using similar tech. Patent war is coming.

I wonder what the difference is between this and the dual sim tech inside my $99 dollar Lumia 650?

The difference is, isheep will insist on Apple did it first.

I was asking an honest question as a lot of what is described in this article I think my Lumia can do. There has to be more to this patent otherwise why would Apple bother... Oh, and I don't call those who prefer Apple as iSheep, so if you want to talk tech then I'm all ears - because that's why I come to this site. Otherwise please troll elsewhere.

iphonearena will call it smoothest dual sim phone and will grant a score of more than 9.5.

Do they need a patent for this? Lmaaaaaoooo

Dual antennas are nothing new, dual active phones already have this. But in the patent it says: Embodiments described herein relate to an apparatus, system, and method for controlling access to multiple antennas in a mobile device. The mobile device may determine priority among a first protocol stack associated with a first subscriber identity module (SIM) in the mobile device and a second protocol stack associated with a second SIM in the mobile device. The mobile device may lock control of a position of a switch to the first protocol stack based on determining the priority among the first protocol stack and the second protocol stack. The switch may control access to the multiple antennas. Accordingly, the second protocol stack may be unable to modify the position of the switch when control of the switch is locked to the first protocol stack. So the way the antennas are prioritized might be new to dual antenna solutions.

Those were my thoughts too.

You're not going to get any green thumbs with logical posts like this...

And Apple shouldn't get a patent (green thumb) for reinventing the wheel. I'm eager for this to come out so you can educate us as to how it's far superior to anything before. My Lenovo K910 Vibe Z was dual-active and I could call myself from the other line and conference it with other "outside" calls from both lines simultaneously if I so wished. I guess that "Stack Protocol" will be described by the likes of you as primitive. But it worked perfect in............... 2013!!

I haven't read the patent myself, and I bet you haven't either, Oracle. So I'd reserve my judgement as I do for anything else Apple or not until I see it in public hands. I'm not ignorant as you usually call me - I see and understand differences between other manufacturers implementations and how they're all different in their own way. I happen to like apples approach more often to tech stuff vs the competition. Not all of apples implementations or approaches are better, but we pick the best of what works for us. If that's ignorance than everyone is ignorant for choosing their own devices.

I don't need to reserve judgment. The best Apple can do to justify their patent is to do it differently but not necessarily better. I have been using dual-sim phones exclusively for the past 5 years (Samsung x2, THL, Nubia, Lenovo x2, Jiayu, iNew, Blackview, Asus x2 and Xiaomi. That's 12 different dual-sim phones if you're counting) so I know quite a bit about them. That's called experience and I would consider myself a target customer for Apple. My $300 4GB Zenfone 2 is dual-active and, from the description in the article, does the exact same thing without resorting to some b.s. geekspeak. All dual-active phones do that and that's all they're describing.

Good thing I only depend on my own self-image ;)
