What is GadgetSIM by CelcomDigi?

Imagine giving each of your favourite gadgets — like tablets, smartwatches, trackers, and even your robot vacuum — its own personal Internet line. That’s exactly what GadgetSIM by CelcomDigi does! It’s a data-only SIM that keeps your smart devices connected on the go, without relying on your phone’s hotspot (and draining its battery in the process). Whether you’re powering up your smart home or need a dedicated line for your kid’s tablet, GadgetSIM delivers fast and reliable 4G/5G Internet, straight to the device.

Available in both physical and eSIM formats, GadgetSIM links up with your CelcomDigi Postpaid 5G plan as a supplementary line. You can choose between two options: the standard GadgetSIM with 30 GB monthly Internet, or go big with GadgetSIM Plus offering 300 GB. Whichever you choose, it’s a seamless way to keep all your gadgets online — no cables, no fuss.

How GadgetSIM works

1. Device-specific Internet

Once activated, each GadgetSIM gets its own dedicated Internet quota — separate from your main phone line. This ensures smooth and uninterrupted connectivity for each connected device. It’s great for anything from light usage like checking emails and controlling smart home devices to heavy usage like video streaming, online classes or HD video calls (especially with the Plus tier).

2. No hotspot, no battery drain

GadgetSIM plugs directly into each device, so you can skip the hotspot hassle. That means your phone battery stays full, and your gadgets get full-speed 4G/5G connectivity — anytime, anywhere.

3. Simple signup and remote control

Getting started is super easy:

4. Supplementary line perks

Each principal postpaid plan can support up to six GadgetSIM supplementary lines. Each line has its own Internet quota — no data sharing or pooling required. Plus, all your billing is centralised under your main account, so you can keep track of everything in one place.

Who should use GadgetSIM?

GadgetSIM is perfect for anyone who wants to keep multiple devices connected without hassle. Here’s who it’s ideal for:

  • Smart home enthusiasts: Keep your IoT devices online 24/7 — even in areas where WiFi doesn’t reach.
  • Busy parents: Equip kids’ tablets with their own mobile data for learning, entertainment and video calls — no hotspot needed.
  • Frequent travellers: Use your tablet or connected devices without depending on your phone while on the move.
  • Remote workers: Enjoy reliable Internet on your laptop or tablet wherever you go — no need for public WiFi or mobile hotspots.
  • Business owners: Set up a second WhatsApp or business line on another device without needing a second phone.

Stay connected, the smarter way

With GadgetSIM by CelcomDigi, your favourite devices can finally go solo — no more draining your phone battery or hunting for hotspots. From smartwatches to tablets and everything in between, each gadget gets its own fast and reliable 4G/5G connection. Just pop in a SIM, fire up the app, and you're good to go. Whether you're building a smart home, raising screen-savvy kids, or working on the move, GadgetSIM keeps life connected, simple, and stress-free.
