eSIM vs roaming: How Malaysians can stay connected abroad

Whether you’re navigating a new country, keeping in touch with loved ones back home, or handling work on the go, staying connected while traveling has become essential in today's world. When it comes to staying online abroad, two main options are available: eSIM and roaming. Whether you are a frequent traveler or planning a one-time getaway, choosing between eSIM and roaming can make a difference in convenience, coverage, and cost. In this article, we explore both options to help you find the best fit for your travels.

What is an eSIM?

An eSIM (Embedded SIM) is a digital version of the traditional SIM card that’s embedded directly into your smartphone. Unlike physical SIM cards, which need to be inserted into the device, the eSIM is built into the device’s hardware.  With eSIM, you can easily switch between networks, whether you're staying with the same provider or choosing a local one while traveling — no new SIM card necessary.

Advantages of eSIM for travel:

• Convenience: With an eSIM, you don’t need to worry about swapping physical SIM cards as you can activate your eSIM digitally before or during your trip.

• Flexible network choices: eSIM gives you the flexibility to switch between local networks or other eSIM providers with just a few taps on your device, allowing you to get the best coverage and rates while traveling.

• Multiple profiles: One of the standout features of eSIM is the ability to store multiple network profiles on the same device. You can switch between different profiles, such as one for your home country and another for international travel, without needing to physically change your SIM card.

What is roaming?

CelcomDigi Roaming allows you to use your mobile phone in a foreign country by connecting to an international network while keeping your original local SIM card and phone number. Roaming is typically activated by your carrier and lets you use your phone for calls, text messages, and data just as you would in your home country. It’s a simple way to stay connected while traveling without changing SIM cards or settings.

Advantages of roaming for travel:

• Simplicity: Roaming provides seamless connectivity without needing to swap out your SIM card. Just activate roaming before your trip, and you can use your local SIM and number in other countries.

• Consistency: For those who rely on staying connected with family, friends, or colleagues while abroad, roaming ensures you can keep using your primary phone number. This is particularly useful for business travellers or those who need to maintain communication in their home country.

• One-time setup: Roaming is typically set up only once before you travel. Once activated, you don’t need to do anything else to use your phone abroad— just turn it on and start connecting.

Comparing eSIM and roaming: Which should you choose?

When deciding between eSIM and roaming for your travels, several factors should be considered, including cost, coverage, convenience, and device compatibility.
‍

1) Cost

Roaming: Roaming charges are typically higher than local rates, especially when traveling internationally. These fees can vary depending on your home network, the country you're visiting, and the data services you use.  

eSIM: Many eSIM providers offer tailored travel packages, where you can purchase local data plans or multi-country options. These plans often come with more transparent pricing compared to roaming, allowing you to better control your budget.  
‍

2) Coverage

Roaming: Roaming generally provides broader network coverage, especially in remote or less-populated areas, where eSIM options might not be as readily available. If you’re traveling to places with limited eSIM providers or remote regions, services such as CelcomDigi Roaming might offer more reliable service to ensure you stay connected.

eSIM: eSIM offers flexibility by allowing you to choose from multiple local networks or international providers, which can lead to better service in some locations. With the right eSIM plan, you can easily switch to a network with strong coverage at your destination, often at lower rates.  
‍

3) Convenience

Roaming: If you’re taking a short trip or prefer simplicity, roaming may be the more convenient choice. With roaming, you don’t have to worry about switching SIM cards or managing multiple plans—just activate roaming with your existing plan and use your phone as usual.

eSIM: For frequent travellers, eSIM is a highly flexible option. With the ability to store multiple network profiles, you can easily switch between local carriers, avoiding the hassle of swapping physical SIM cards. This is especially useful if you’re visiting multiple countries on a single trip and want the flexibility to choose the best local network in each location.
‍

4) Compatibility

Roaming: If you’re using an older device that doesn’t support eSIM, roaming might be the better option. CelcomDigi Roaming works seamlessly with traditional SIM cards, so if you haven’t upgraded your phone yet, you can still use your local SIM card abroad without any issues.

eSIM: Keep in mind that eSIM requires a device that supports this technology. Most modern smartphones, such as the latest iPhones and Android devices, are eSIM-compatible, but older models may not support it.  

Ultimately, the choice between eSIM and roaming depends on your travel habits and needs. If you’re looking for flexibility, cost control, and modern device compatibility, eSIM is a great option, especially for frequent travellers. On the other hand, if you prefer simplicity, have an older device, or need reliable coverage in remote areas, CelcomDigi Roaming could be the better option for your trip. Consider factors like cost, network coverage, and the type of trip you’re taking to make the best choice for staying connected abroad.
