Why eSIMs Are the Smart Traveller's Best Friend - Especially in South Africa
Category News
Gone are the days when you needed to hunt down a mobile store right after landing off a long-haul flight, or lug around a second cellular phone to carry your SA sim, or worse still, having to remember to keep your SA sim number active in-between your regular visits to our beautiful Hermanus. More and more globetrotters are discovering the convenience of eSIMs - a digital alternative to traditional SIM cards that's changing how we stay connected on the move. If you're planning a trip to Hermanus eSIMs offer a flexible, affordable, and hassle-free way to stay online, make calls, and even keep your usual number active while travelling.
What Is an eSIM?
An eSIM (embedded SIM) is a digital SIM that's built into your smartphone, tablet, or smartwatch. Unlike traditional SIM cards, there's no physical chip to insert or swap out. Instead, you download a data or call package directly to your device .
eSIM Networks in South Africa
South Africa is increasingly eSIM-ready. Major networks such as MTN, Vodacom, Cell C, and Telkom now support eSIMs on selected devices. You can activate a local package directly through one of these providers if you're staying a while and need a South African number with call and data capability.
Many travel-junkies opt for international eSIM providers such as:
- Holafly: Offers regional and global data packs with excellent coverage in South Africa and dozens of other countries. Perfect for those travelling through multiple destinations in Africa or globally.
- Airola: Known for competitive pricing and user-friendly activation, Airola supports a wide range of travel data packages for South Africa and beyond. Their coverage often includes data bundles that auto-renew or allow top-ups.
What Can You Use Your eSIM For?
eSIMs can be data-only or include voice and SMS, depending on the provider and plan you choose. For most travellers, a data-only eSIM is sufficient - allowing you to use WhatsApp, Google Maps, ride-hailing apps, and online bookings with ease.
If you need to make traditional phone calls or send local SMS messages - for example, to call a restaurant or accommodation - consider a data + call package, available via South African networks or some global eSIM providers.
Can I Use My Regular Number Too?
Yes! One of the best features of an eSIM is the ability to run it alongside your primary number (if your device is dual SIM capable). You can choose which SIM handles calls, messages, or data, and toggle one or both lines on or off as needed. For example:
- Keep your home number active for two-factor authentication or important texts.
- Use your eSIM for data to avoid international roaming charges.
What Phones Support eSIM?
Most modern smartphones support eSIMs, including:
- Apple: iPhone XS, XR, 11, 12, 13, 14, 15 series and newer (some support dual active eSIMs)
- Samsung: Galaxy S20 and newer, Z Flip/Fold series, Note 20 Ultra and newer
- Google: Pixel 3 and newer
- Huawei: Select models (eSIM support may vary by region)
Note: Not all phones support eSIMs or dual-SIM functionality, and regional firmware can limit support - always double-check with your provider or manufacturer.
How Many eSIMs Can You Have?
Depending on your phone model, you can store up to 5-20 eSIMs, though only one or two can be active at a time. This means you can preload eSIMs for future travel or switch between providers when crossing borders.
Do eSIM Numbers Expire?
Most eSIM data plans are temporary, valid for 7, 15, or 30 days - ideal for short stays. However, some providers let you retain your eSIM number or re-use the same eSIM profile when you return to the same country, making it a convenient option for frequent visitors.
