Exploring the Pros and Cons of eSIM vs Physical SIM Cards

14 May,2024 - Yangon | 3 mins read

Author: Srinivas Rao, Chief Information Officer at ATOM

As customers explore this exciting advancement, it is important to understand the advantages and limitations of both eSIM (embedded SIM) and traditional physical SIM cards to make informed choices. ATOM is proud to have introduced eSIM technology in Myanmar at the start of 2024. Our eSIM offering marks a significant step towards a more streamlined and convenient mobile experience. The successful launch of ATOM's eSIM can be attributed to our cross-functional team's capabilities, with various departments working collaboratively to deliver the eSIM project within a remarkable timeframe of eight months.

With both options now available in the market, how do you determine which is best for you? This article will guide you through the pros and cons of using an eSIM compared to physical SIM cards.

Understanding eSIM and Physical SIM Cards

We are all familiar with the physical SIM card – a small chip inserted into your phone that connects you to your carrier’s network. Switching network is simple: you swap out your SIM card from one carrier to another.

An eSIM is like a digital SIM card. It functions exactly like a traditional SIM card, but without the need for the physical card. It's a chip in your device that can be programmed and securely stores your mobile profile. With an eSIM, you can switch between mobile plans without changing physical cards. You can activate an eSIM in different ways. ATOM uses a simple QR code method or swaps your physical SIM card for an eSIM.

Let’s look at the pros and cons of each option.

eSIM Pros & Cons

Pros

Cons

Convenience: No need to keep multiple physical SIM cards. Users can switch between carriers or plans by downloading a new profile on the device.

Limited Device Compatibility: Currently, eSIM support is not as widespread as physical SIM cards, particularly in older device models.

Durability: eSIMs eliminate the risk of physical damage common with SIM cards.

Carrier Limitations: Not all carriers offer eSIM services yet, and the activation processes can vary between providers.

Security: eSIMs are tamper-proof and reduce the risk of theft and unauthorised access, enhancing users’ data security.

Potential Activation Challenges: The activation process might be challenging for less tech-savvy users. People might find it tedious to set up an eSIM again when they switch devices.

Flexibility: eSIMs allow users to have multiple lines on a single device, perfect for travel.

Physical SIM Pros & Cons

Pros

Cons

Wide Device Compatibility: Physical SIM cards are compatible with a variety of devices, from basic phones to the latest smartphones.

Risk of Loss or Damage: Physical SIM cards can be misplaced, stolen or damaged. Replacing a lost or damaged SIM card can be costly or time-consuming.

Simplicity of Use: Switching SIM card between devices is straightforward.

Inconvenience When Switching Networks:  Switching carriers requires obtaining a new SIM card, which often means having to visit a store in person.

Easy Activation: Physical SIM cards can be activated without an internet connection, making them convenient for areas with limited internet access.

In summary, while physical SIM cards will remain popular due to its wide compatibility and ease of use, eSIMs offer an array of benefits, including convenience, flexibility and enhanced security. Embracing eSIM technology not only streamlines your mobile experience, but also prepares you for future advancements in mobile technology.

Beyond smartphones, eSIM technology is transforming various industries. Here are a few examples:

  • Connected Cars (Automotives): eSIMs enable seamless connectivity and remote diagnostics for connected vehicles.
  • Connected Consumer Devices: Smartwatches, laptops, and tablets can leverage eSIMs for cellular connectivity without relying on a smartphone hotspot.
  • Smart Cities: eSIMs can play a crucial role in managing traffic flow, waste collection, and other smart city applications.
  • Logistics: eSIM-equipped trackers can ensure real-time monitoring and efficient management of fleets and logistics operations.
  • Home Security: eSIMs can provide reliable connectivity for home security systems, ensuring they remain operational even during internet outages.
  • Healthcare: eSIMs can connect medical devices and wearables, enabling remote patient monitoring and improved healthcare delivery.
  • Internet of Things (IoT): eSIMs are a key driver of IoT growth, allowing seamless and secure connectivity for a vast array of devices.

At ATOM, we are committed to providing our customers with Beyond Better experiences. We now offer eSIM alongside physical SIM card options, giving customers the flexibility to choose what works best for them.

Currently, customers need to visit an ATOM store to get the eSIM installed in their handset. In the near future, customers can conveniently obtain the ATOM eSIM online via our website or the ATOM Store App. To learn more about our eSIM service, visit our website or stop by an ATOM store to chat with our team.
