Planning a trip to South America and trying to decide between an eSIM from LATAM Travellers or a traditional physical SIM card? It's a common question, and the answer depends on your specific needs and travel style.
Here's an honest, practical comparison to help you make the right choice for your trip.
What's the Difference?
Physical SIM Card: The traditional plastic card you insert into your phone's SIM tray. You typically purchase these at stores, kiosks, or airports in your destination country.
eSIM: A digital SIM embedded in your phone that you activate with a QR code. You purchase it online before your trip and install it on your device remotely.
| Feature | eSIM | Physical SIM |
|---|---|---|
| Setup Time | Minutes (QR code scan) | 30-60 min (store visit) |
| Buy Before Travel | Yes | No (in-country only) |
| Keep Home Number | Yes (dual SIM) | Need to swap cards |
| Multi-Country | Easy -- switch plans digitally | New SIM per country |
| Device Support | Modern phones (2019+) | Any unlocked phone |
| Local Phone Number | Usually data-only | Often included |
| Risk of Loss | None (digital) | Tiny card can be lost |
The Honest Comparison
Convenience
eSIM Wins:
- Install from home before your trip
- Activate automatically when you land
- No hunting for stores or dealing with lines
- Perfect if you're landing late at night or on weekends
Physical SIM:
- Need to find a store (not always easy)
- May require waiting in line
- Store hours can be limited
- Potential language barriers
Cost
Physical SIM Can Be Cheaper:
In some countries, local physical SIM cards from major carriers can be less expensive, especially for extended stays (30+ days). However, you save time and hassle with an eSIM from LATAM Travellers.
eSIM Value:
eSIMs are competitively priced and often cheaper than your home carrier's roaming fees. The time saved and convenience usually justify any small price difference.
Device Compatibility
Physical SIM Works in Most Areas:
Any unlocked phone with a SIM tray can use physical SIMs, including older models.
eSIM Requires Modern Phones:
You need a newer device (iPhone XR+, Pixel 4+, Galaxy S20+). Your phone must also be unlocked. Check compatibility before purchasing.
Flexibility
eSIM Wins:
- Keep your home SIM active simultaneously
- Switch between plans without swapping physical cards
- Perfect for multi-country trips
- Can't lose or damage a digital SIM
Physical SIM:
- Need to physically swap cards
- Easy to lose tiny SIM cards
- Can only use one at a time (unless dual SIM phone)
- Can reuse or transfer to another phone if needed
When Physical SIM Might Make Sense
Physical SIMs can be the better choice in certain specific situations:
- Extended stays (30+ days): Local carrier plans may offer better value for long-term visits
- Older phone: If your device doesn't support eSIM technology
- Need a local phone number: Some physical SIM plans include calling minutes and a local number (eSIMs are typically data-only)
- Unlimited data: Some local carriers offer unlimited data plans that eSIM providers don't match

Frequently Asked Questions
Is eSIM better than a physical SIM for travel?
Yes, for most travellers. eSIM offers instant activation, no risk of losing a tiny card, and the ability to keep your home number active simultaneously. Physical SIMs only win if your phone does not support eSIM.
Can I use both an eSIM and a physical SIM?
Yes. Most modern smartphones support dual SIM — one physical and one eSIM. This lets you keep your home number for calls while using the eSIM for affordable local data abroad.
Does my phone support eSIM?
Most phones from 2020 onwards do. iPhones from XS and later, Samsung Galaxy S20+, Google Pixel 3a+, and many other Android devices support eSIM. Check your phone settings or manufacturer's website to confirm.
What happens to my eSIM when I leave South America?
It simply stops working when you leave the coverage area. Your eSIM plan expires based on its validity period. You can delete it from your phone settings or keep it for your next trip if data remains.
