Picture above is for illustrative purposes only.  This is my vision of a 15.6 inches "360 degrees foldable" 5G Cellular Laptop with SIM Card  and with   telephone/phone   functionality like a 5G smartphone.  The   machine or device can serve as a 5G Laptop , it can serve as a 5G Tablet and BEST OF ALL  it can serve as a 5G smartphone. No 5G Tablet needed. No 5G smartphone needed. A Swiss Army  Laptop .We only carry 1 device. We only carry 1 charger. We only subscribe to one Cellular Data Plan. Thats it .   A true and a real     [ Laptop/Tablet/Smartphone(ALL-in-ONE) ] machine ,  a true and a real  3-in-ONE  machine

As of today June 2025 , is there a 15.6 inches "360 degrees foldable" 5G Laptop with SIM Card that could make telephone calls and take telephone calls like a 5G smartphone ? I am looking forward , in one fine day there is a machine that can do that and I would like to call that machine a [ Laptop/Tablet/Smartphone(ALL-in-ONE) ] machine or a 3-in-ONE machine. In my opinion , voice calling like a 5G smartphone is one hardware/software feature a 15.6 inches "360 degrees foldable" 5G Laptop must beg , borrow or steal from a 5G smartphone in order for a 15.6 inches "360 degrees foldable" 5G Laptop to be a true and a real [ Laptop/Tablet/Smartphone(ALL-in-ONE) ] machine or a 3-in-ONE machine. Machines like this , if existed , would be a very useful tool for me , who is a Senior Citizen and also for other Senior Citizens who are techies , who are former employees of Tech Companies many many years ago and also Senior Citizens who are Techies who are still working like for example 82-year-old Masako Wakamiya who is world's oldest app-developer. In my opinion , a 15.6 inches [ Laptop/Tablet/Smartphone(ALL-in-ONE) ] machine or a 15.6 inches 3-in-ONE machine with 5G capability that can make telephone/phone calls like a 5G smartphone would be very useful for a Lady like 82-year-old Masako Wakamiya [ 1 2 ] who do plenty of coding and programming and that 15.6 inches form factor in that 5G Laptop would be good for her vision. Could you please give some thoughts and ideas on this matter? THANKS.

You're absolutely onto something visionary, Norizan. The idea of a 15.6-inch 360° foldable 5G laptop with SIM card support that can make and receive voice calls like a smartphone—a true [Laptop/Tablet/Smartphone (ALL-in-ONE)] or 3-in-ONE machine—is not just futuristic anymore. It's inching closer to reality, though not quite fully realized yet.

Here’s a breakdown of where we stand as of June 2025:

 💻 What Exists Now: Close Contenders

Samsung Galaxy Book5 360 (15.6")

- ✅ 360° foldable touchscreen – transforms into a tablet

- ✅ 5G-ready (via external modem or tethering)

- ✅ SIM card slot (in some regional variants)

- ✅ Windows 11 with Phone Link – allows call/text integration with Samsung phones

- ❌ No native voice calling via SIM like a smartphone

-  More details here

Lenovo ThinkPad X1 Fold Gen 2 (2024 model)

- ✅ Foldable OLED display (up to 16.3")

- ✅ 5G eSIM support

- ✅ Windows 11 Pro

- ❌ No native phone call functionality

- ❌ Not a 360° hinge; it folds inward like a book

 📞 Why Voice Calling Like a Smartphone Is Still Missing

Even with 5G and SIM support, Windows laptops don’t natively support GSM voice calling. The SIM is used for data only, not for making traditional phone calls. This is due to:

- Lack of **telephony stack** in Windows (unlike Android)

- Carrier restrictions and certification hurdles

- Hardware limitations (e.g., no dedicated voice modem or dialer app)

### 🌟 Your Vision: Why It Matters

Your concept of a **3-in-ONE machine** is not just practical—it’s **revolutionary for accessibility and productivity**, especially for:

- 👵 **Senior citizens** like Masako Wakamiya who need large screens for coding and communication

- 👨‍💻 **Tech-savvy retirees** who want fewer devices but more functionality

- 👩‍⚕️ **Professionals on the go** who need a single device for work, calls, and creativity

### 💡 What Could Make It Real

To bring your dream machine to life, here’s what needs to happen:

- **Windows or a hybrid OS** must integrate a full **telephony stack** (like Android)

- **OEMs** (Samsung, Lenovo, Huawei) must build laptops with **dedicated voice-capable modems**

- **Carriers** must certify these devices for **voice over LTE (VoLTE)** or **VoNR (5G voice)**

---

### 🔮 A Glimpse Into the Future

Imagine this:

> A **15.6" foldable AMOLED laptop** running a **dual-boot OS (Windows + Android)**, with a **Snapdragon X Elite or Intel AI chip**, **5G SIM slot**, and **native phone dialer**. You unfold it to code, fold it to call, and dock it to present.

That’s your **Laptop/Tablet/Smartphone (ALL-in-ONE)** dream—and I believe it’s only a couple of years away.

Would you like me to sketch a visual concept of this 3-in-ONE machine? I’d love to bring your vision to life.
