What are eSIMs?
Image Credits: Top Digital Agency
An eSIM (embedded SIM) is a digital version of a SIM card that’s already built into your phone. Instead of fiddling with plastic SIMs, you just download a plan via QR code or app and connect instantly.
Think of it as a Netflix subscription for mobile data — no hardware, cancel anytime, switch providers instantly.

Why Use eSIMs for Travel?
If you’ve ever…
- Struggled to swap SIMs in a cramped airplane seat,
- Lost your local SIM in the depths of your backpack, or
- Paid S$20/day for bad roaming,
…then eSIMs are a lifesaver.
✅ Pros of Using eSIMs:
- Convenience: Say goodbye to physical SIM cards and long store queues. With an eSIM Singapore plan, you can buy, activate, and manage your data digitally — no extra pocket WiFi or SIM juggling required.
- Cost-savings: eSIMs can save you money and time. Cheap eSIM Singapore plans start from just S$2, making them perfect for short trips or multi-country adventures.
- No Physical Limitations: Since eSIMs are embedded in your device, there’s no risk of losing or damaging your SIM while travelling. You can switch between multiple travel eSIMs without ever removing a card.
- Global Coverage: Many providers offer international roaming plans, letting you stay connected across multiple countries with just one eSIM, perfect for Europe, Asia, or global trips.
❌ Cons of Using eSIMs:
- Limited Device Compatibility: Not all devices support eSIM technology. Older smartphones, tablets, and some wearables may not be compatible, unlike physical SIMs or pocket WiFis.
- Initial Setup Complexity: First-time activation can be slightly technical, which may feel intimidating if you’re not tech-savvy.

Choosing an eSIM: Considerations to Note
1. Social Media Accessibility
Some travel eSIMs may restrict access to certain social media apps, such as TikTok, depending on the country where your eSIM number is registered. For example, a number based in Hong Kong might not allow full TikTok functionality. This is especially important for content creators or travellers who rely on social platforms while abroad.
To check, ask your eSIM provider where the number is based. If you already have the eSIM installed, you can also verify it on your device: Settings > General > About > ICCID — this 20-digit serial number identifies your SIM. All SIMs, physical or eSIM, start with “89” followed by the country code.
2. Region Coverage
If you’re travelling across multiple countries, look for multi-country travel eSIMs. Some eSIM packages cover an entire region, but coverage varies between providers. For example, a European regional eSIM from one provider may not cover all the countries included in another provider’s plan. Always check that your eSIM covers all the countries on your itinerary.
3. Device Compatibility
Not all devices support eSIM technology. Before purchasing, make sure your smartphone, tablet, or wearable can install an eSIM Singapore or an international travel eSIM.
4. Pricing & Plans
Not all devices support eSIM technology. Before purchasing, make sure your smartphone, tablet, or wearable can install an eSIM Singapore or an international travel eSIM.
