How do dual SIM phones work?
So, how exactly do dual SIM phones work? Dual SIM phones operate by having multiple SIM cards in a single device. This can be particularly handy for folks who need to juggle two separate phone numbers, one for personal use and another for work, all on the same phone. It's also a great fit for users who prefer to keep their mobile calls & texts separate from their internet data plan, giving them more control over their phone services. While the exact features might differ depending on the phone model, the basic idea of a dual SIM phone remains the same: having multiple SIMs working within a single smartphone.
A 2023 report by Counterpoint Research indicates a staggering 30% year-over-year growth in smartphone shipments with dual SIM (including eSIM) support, highlighting the growing popularity of this technology. This surge is likely fueled by the increasing demand for cost-effective data roaming solutions for international travellers.
For travellers, the advantages are even more pronounced. Dual SIM phones empower you to leverage your home SIM card for calls and texts, while simultaneously utilising a travel eSIM for affordable data rates in your destination country.
Traditional Dual SIM vs eSIM. Does it Matter?
There are two main categories of dual SIM phones: Dual SIM Dual Active (DSDA) and Dual SIM Dual Standby (DSFA).
DSDA phones allow both SIM cards to be active simultaneously. This means you can receive calls and texts on both numbers, without needing to switch between them.
DSFA phones, on the other hand, can only have one SIM card active at a time. You'll need to manually switch between the SIMs to receive calls and texts. While less convenient than DSDA, DSFA phones offer better battery life.
Here's where eSIM technology enters the game. An eSIM (embedded SIM) is a digital SIM card that is built directly into your smartphone. This eliminates the need for a physical SIM card, allowing you to store and switch between multiple profiles on the same device.
Traditional SIM cards can be easily lost or damaged, but eSIMs offer a secure alternative. Additionally, eSIMs enable remote provisioning, allowing you to purchase and download travel data plans online before your trip, eliminating the hassle of searching for a local SIM card upon arrival.
How Dual SIM Phones Benefit Travellers?
The integration of eSIM technology with dual SIM phones unlocks a world of convenience for travellers. Here are some of the key benefits:
- Reduced Roaming Charges: By utilising a travel eSIM data plan, you can avoid the expense roaming charges from your home telco. Using your eSIM data to stay connected with friends and family back home, use navigation apps, and access the internet without the worry of hidden fees. According to a GSMA Intelligence report, mobile data usage by international travellers is expected to reach a whopping 77 exabytes per year by 2025. With eSIMs, travellers can add a second cost-effective data plan, to meet their growing demands.
- Seamless Connectivity: With a travel eSIM pre-installed you'll have instant internet access upon landing at your destination. This eliminates the need to search for a local SIM card vendor or wait in line to activate a new service. You can stay connected from the moment you arrive, allowing you to make travel arrangements, book rideshares, and connect with loved ones back home.
- Business and Personal Calls: Dual SIM phones are ideal for users that want to be reachable on both a work and personal number. You can easily switch between SIM cards to manage calls and messages without needing to carry two separate devices.
- Security and Flexibility: eSIMs offer an extra layer of security compared to traditional SIM cards. Since they are embedded in your phone, they cannot be easily lost or stolen. Additionally, eSIMs provide the flexibility to switch between different data plans based on your needs and travel destination.

Frequently Asked Questions
What are the disadvantages of a dual SIM phone?
While dual SIM phones offer convenience, there are a few potential drawbacks. DSFA (Dual SIM Dual Active) phones can only have one SIM active at a time, requiring manual switching to receive calls/texts on the other number. Additionally, having two active SIMs can drain battery life faster. There's also a risk of confusion if you accidentally use the wrong SIM for calls or data.
Can a data eSIM be used for voice calls too?
Most eSIM data plans primarily provide mobile data usage, not traditional voice calling minutes. However, while traditional voice calling may be limited, eSIMs can enable VoIP data-based calling, using apps like WhatsApp, Skype or FaceTime, as long as you have an active data connection.
How do you switch between SIMs on a dual SIM phone?
The process varies by phone model but generally involves going into the Settings app and selecting the desired SIM for voice calls, texts, and mobile data. On iPhones, there's a dedicated "Mobile" menu to switch SIMs. Android phones often have a "SIM cards" or "Dual SIM" option in Settings. Some models also allow quickly switching SIMs from the notification screen.
