Activating a Digi SIM card requires a valid identity document (MyKad or Passport) and the completion of the Electronic Know Your Customer (eKYC) process via the MyDigi application. Successful activation is characterized by the device latching onto the CelcomDigi network and receiving a confirmation SMS, a process that typically concludes within five minutes but may take up to 24 hours under regulatory review.


Pre-Activation Requirements and Hardware Checklist

Before initiating the activation sequence, ensure you have all the necessary components and meet the regulatory criteria set by the Malaysian Communications and Multimedia Commission (MCMC). Failure to provide authentic documentation or using a damaged SIM card will result in a registration rejection.

Essential Components and Prerequisites:



  • Physical SIM Kit: A new, unexpired Digi Prepaid or Postpaid SIM pack. Ensure the 19-bit or 20-bit Integrated Circuit Card Identifier (ICCID) number on the back of the SIM is legible.
  • Valid Identification: For Malaysian citizens, an original MyKad (IC) is mandatory. For non-citizens, a valid international passport with at least six months of validity is required. Physical documents are necessary for the eKYC scanning process; photocopies or digital images on other screens will be rejected.
  • Compatible Hardware: A smartphone with a functioning rear camera (for document scanning) and front camera (for facial recognition). The device must be unlocked and compatible with GSM/LTE/5G NR bands (Bands 1, 3, 7, 8, and 28 are standard for Digi).
  • Internet Connectivity: A secondary Wi-Fi connection or existing mobile data is required to download the MyDigi application and upload biometric data.
  • Estimated Duration: The digital self-registration process takes approximately 5 to 10 minutes. Network provisioning usually completes within 30 minutes of successful biometric verification.

Phased Execution: Registering and Activating Your Digi SIM

The modern activation workflow has transitioned from SMS-based triggers to a secure, app-based environment to comply with anti-fraud regulations. Follow these steps precisely to ensure your mobile identity is correctly provisioned on the CelcomDigi infrastructure.



Step 1: Physical Preparation and App Installation

Begin by carefully removing the SIM card from its plastic housing. Digi provides a "Triple-SIM" format, allowing you to snap out the Standard, Micro, or Nano size. Most modern smartphones utilize the Nano-SIM format.



  1. Power off your mobile device to prevent electrical shorts or SIM tray errors.
  2. Insert the SIM card into the primary slot (Slot 1).
  3. Power on the device. At this stage, you may see "No Service" or "Emergency Calls Only," which is normal for an unactivated card.
  4. Connect your device to a stable Wi-Fi network.
  5. Navigate to the Google Play Store, Apple App Store, or Huawei AppGallery and search for "MyDigi." Download and install the latest version of the application.


Step 2: Initiating the EKYC Process

The Electronic Know Your Customer (eKYC) process is a legal requirement in Malaysia to prevent identity theft and fraudulent telecommunications usage.



  1. Open the MyDigi app and select the "Activate SIM" or "Register SIM" option on the splash screen.
  2. The app will request access to your camera. Grant these permissions to proceed.
  3. Scan the barcode or QR code located on the SIM card starter pack. This automatically links the ICCID and the assigned MSISDN (your mobile number) to the registration session.
  4. If the scanner fails, manually input the serial number found on the back of the SIM card.


Step 3: Document Verification and Biometric Matching

This is the most critical phase where the system matches your physical identity with your government-issued ID.



  1. Place your MyKad or Passport on a flat, well-lit surface. Avoid using a camera flash, as glare can obscure security features.
  2. Follow the on-screen guides to capture the front and back of your MyKad. For passports, ensure the machine-readable zone (MRZ) at the bottom is clearly visible.
  3. The system will perform an Optical Character Recognition (OCR) scan to extract your name, ID number, and address. Verify that this information is correct.
  4. Face Verification: The app will switch to the front-facing camera. Position your face within the oval frame. You may be prompted to blink, nod, or turn your head to prove "liveness" and prevent the use of static photos.

Warning: Ensure you are in a room with neutral lighting. Excessive backlighting (like standing in front of a window) will cause a biometric mismatch, leading to a "Failed Verification" error.



Step 4: Plan Selection and Confirmation

Once your identity is verified, you must finalize the plan parameters associated with your SIM.



  1. Review the prepaid or postpaid plan details displayed on the screen.
  2. Select any "Add-on" bundles if you are using a specialized traveler or social media pack.
  3. Accept the Terms and Conditions and click "Submit."
  4. You will receive a "Registration Successful" notification. At this point, the backend systems begin the provisioning process (HSS/HLR updates).


Step 5: Network Latch and APN Configuration

After the app confirms successful registration, your phone needs to synchronize with the local cell towers.



  1. Restart your phone. This forces the device to perform a fresh "Location Update" with the network.
  2. Wait for the signal bars to appear. You should receive a series of "Welcome" SMS messages from Digi (usually from the shortcode 20000 or 128).
  3. APN Settings: If you have signal bars but no internet access, you must manually configure the Access Point Name (APN).

    • Android: Settings > Connections > Mobile Networks > Access Point Names > Add.
    • iOS: Settings > Cellular > Cellular Data Network.
    • Name: Digi Internet
    • APN: diginet (Note: For some 5G-enabled SIMs, use celcomdigi).
    • Leave Username and Password blank.
    • Save and select this APN.

Pro-Tip: Dial *126# to check your credit balance and *128# to manage your account via the USSD menu. If these codes return a response, your SIM is fully active.

Common Activation Failures and Resolution Protocols

Even with automated systems, technical friction can occur during the registration lifecycle. Most issues stem from document legibility or network latency.



  • Failure Scenario: "Invalid ID" or "OCR Read Error"



    • Root Cause: The camera failed to capture the holographic security features of the MyKad or the MRZ of the passport due to poor lighting or lens smudge.
    • Actionable Fix: Clean your camera lens with a microfiber cloth. Place the ID on a dark, non-reflective background and ensure the four corners of the ID are within the on-screen frame. Avoid using the flash.
  • Failure Scenario: No Signal Bars After 24 Hours



    • Root Cause: The SIM provisioning failed at the HLR (Home Location Register) level, or the SIM card itself is defective.
    • Actionable Fix: Test the SIM in a different mobile device. If it remains inactive, visit a Digi Store or CelcomDigi center for a 1-to-1 SIM swap. You will need to bring your ID for manual verification by a staff member.
  • Failure Scenario: MCMC Limit Exceeded



    • Root Cause: Malaysian regulations limit individuals to five (5) prepaid SIM cards per service provider.
    • Actionable Fix: Check how many active SIMs are registered under your ID. If you have reached the limit, you must terminate an old, unused SIM at a Digi outlet before you can activate a new one.
  • Failure Scenario: EKYC Liveness Test Rejection



    • Root Cause: The system detected a "non-live" entity, often caused by wearing glasses, hats, or masks, or having hair covering the eyes.
    • Actionable Fix: Remove all facial accessories and ensure your forehead and ears are visible. Perform the movements (blinking/smiling) slowly and deliberately when prompted by the app.

Frequently Asked Questions



Can I activate my Digi SIM card if I am currently outside of Malaysia?

You cannot activate a new Digi SIM card while roaming abroad because the initial registration requires a latch to a local CelcomDigi cell tower to complete the provisioning handshake. Furthermore, the MyDigi app EKYC process often uses geo-fencing to ensure the user is within Malaysian borders during the registration of a local telecommunications asset.



How long does it take for a port-in (MNP) SIM to activate?

Mobile Number Portability (MNP) activations take longer than new number registrations, typically between 24 and 48 business hours. You must keep your old SIM in the phone until it loses signal; once the old service is cut, insert your new Digi SIM, and it should activate automatically within minutes of the network switch.



What should I do if the MyDigi app crashes during the EKYC scan?

If the application crashes, clear the app cache in your phone settings and ensure your operating system (iOS or Android) is updated to the latest version. Restart the process from Step 2; the system should recognize your SIM barcode and allow you to resume the biometric upload without purchasing a new kit.



Is there a way to activate a Digi SIM card without using a smartphone?

While the MyDigi app is the primary method for self-activation, individuals without a compatible smartphone can visit any authorized Digi Dealer, Digi Store, or CelcomDigi flagship outlet. A representative will use a specialized dealer portal to scan your ID and activate the SIM on your behalf.



Does the Digi SIM card expire if not activated immediately?

Yes, every Digi SIM starter pack has an "Expiry Date" printed on the back of the envelope or the SIM card carrier. If you do not perform the activation process before this date, the ICCID will be purged from the database and the mobile number will be recycled, rendering the physical SIM card useless.

Maximize Your Mobile Experience

After successfully activating your SIM, explore the MyDigi app to discover exclusive "Box of Surprise" deals and high-speed 5G internet passes tailored to your usage patterns. Staying connected has never been more seamless with Malaysia’s widest network coverage following the CelcomDigi integration.
