In 2025, staying connected has never been more important. With Malaysia’s internet penetration at 97.7% and mobile connections exceeding the total population, most Malaysians already carry more than one mobile line. But the days of juggling multiple physical SIM cards are ending.


Enter eSIM (embedded SIM) — a digital alternative that makes switching networks, buying travel data, and managing mobile numbers easier than ever.

If you’ve ever asked “What is eSIM and how can I use it in Malaysia?”, this guide is for you.


What is eSIM?

An eSIM (short for embedded SIM) is a digital SIM card built directly into your phone, smartwatch, or device. Unlike physical SIM cards, eSIMs don’t require a plastic chip — instead, your telco sends a QR code or app-based activation to load a mobile profile onto your device.


Global & Regional Adoption


The rise of eSIM is not just hype — it’s backed by strong numbers:

  • 1.1 billion eSIM devices were active globally in 2024

  • By 2028, shipments of eSIM-enabled devices are projected to hit 590 million units annually

  • By 2025, 60% of new smartphones sold worldwide will support eSIM

  • The eSIM services market is growing at a 22% CAGR through 2032

  • For travel use, eSIM adoption is projected to surge 50% annually in the coming years


In Asia-Pacific, including Malaysia, telcos are rapidly adopting eSIM as demand grows.

Benefits of eSIM for Malaysians


✅ Convenience – No need to queue at telco counters. Activate instantly via QR code.

✅ Flexibility – Store multiple lines (e.g., Digi for local, Airalo for travel) on one phone.

✅ Travel savings – Buy travel eSIMs before flying; skip expensive roaming charges.

✅ Dual connectivity – Keep your Malaysian number active while using a foreign data plan.

✅ Security – Harder to tamper with or steal compared to physical SIMs. ✅ Affordability - Travel eSIMs are more affordable & accessible compared to roaming - certain roaming plans are limited to existing telco customers only.


Challenges & Limitations


⚠️ Device compatibility – Not all phones support eSIM (mostly mid-to-premium models).

⚠️ Telco availability – Some local telcos still limit eSIM to postpaid or certain plans.

⚠️ One active profile – Most devices allow multiple eSIMs stored, but only one or two active at a time.

⚠️ Consumer awareness – Many Malaysians still prefer physical SIMs due to habit.

Insurance & Security Angle


As an insurer, we also want Malaysians to understand the security benefits of eSIM:

  • Reduced risk of SIM swap fraud, since no physical SIM can be stolen.

  • Easier to lock down a phone remotely if lost, compared to physical SIMs.

  • When paired with mobile protection insurance, users gain peace of mind against theft, hacking, and device damage.


Conclusion


eSIM is changing the way Malaysians connect — whether at home or abroad. With growing telco support, global adoption, and device compatibility, it’s only a matter of time before eSIM replaces physical SIMs entirely.


For Malaysians, the best approach is hybrid: use a local telco eSIM for daily life, and a travel eSIM for affordable roaming. And as digital connectivity evolves, don’t forget to also protect your devices with mobile insurance — because being connected is only valuable if you’re also protected.
