Why most travel eSIMs are data only
One of the first things many travellers notice when comparing eSIM plans is that a large number of them are described as data only.
At first, this can seem confusing. People often assume that without traditional calls or SMS included, the eSIM will somehow be limited or difficult to use while travelling abroad.
In reality, most modern travel habits now rely far more heavily on mobile data than traditional minutes and texts.
Navigation, messaging, restaurant bookings, ride hailing apps, boarding passes and travel planning tools all primarily work through an internet connection rather than standard mobile calls.
How travellers communicate abroad today
Over the last few years, messaging apps have largely replaced traditional international texting for many travellers.
Apps such as WhatsApp, iMessage, Telegram, Messenger and FaceTime all work through mobile data or Wi-Fi, allowing travellers to stay connected almost anywhere without needing local call minutes.
This also applies to voice and video calls. Many travellers now make the majority of their calls through internet based apps rather than through standard mobile networks.
As long as you have a stable data connection, communication abroad is usually straightforward.
Travel apps rely on data, not traditional calls
Modern travel itself is increasingly built around mobile apps.
Ordering food, booking taxis, checking train times, translating signs, using digital boarding passes and navigating unfamiliar cities all depend primarily on mobile data access.
For many travellers, the most frustrating issue abroad is not the lack of traditional calls or SMS, but losing access to maps, transport apps or internet based messaging.
That is one of the reasons data focused travel eSIMs have become so popular in recent years.
When calls and SMS can still be useful
Although many travellers are perfectly comfortable using data only plans, there are still situations where traditional calls or SMS may be important.
Some travellers prefer having a standard phone number while abroad, especially for:
- Calling hotels or restaurants directly
- Receiving SMS verification codes
- Business travel
- Emergency local communication
- Destinations where internet apps are less commonly used
In these situations, choosing a plan that includes telephony features may be useful depending on your travel style and destination.
Using your normal SIM alongside a travel eSIM
Many modern smartphones support using both a physical SIM card and an eSIM at the same time.
This allows travellers to continue using their normal number for calls and SMS while using the travel eSIM primarily for mobile data abroad.
For some travellers, this offers a useful balance between staying connected and avoiding expensive roaming charges for mobile data usage.
How to find plans that include calls or SMS
Not every travel eSIM is data only.
Some providers do offer plans with traditional calls, SMS or additional telephony features depending on the destination and network.
If having calls or SMS is important for your trip, using advanced comparison filters can make it easier to narrow down plans that match your requirements.
Choosing the right setup for your trip
The best option ultimately depends on how you travel and how you normally use your phone abroad.
For many travellers, a reliable data connection combined with apps such as WhatsApp and FaceTime is more than enough for staying connected throughout a trip.
Others may prefer the reassurance of traditional calls and SMS, particularly for business travel or longer stays.
Understanding the difference between data only plans and telephony enabled plans can make it much easier to choose the right eSIM before travelling.
