eSIM vs Local SIM: The Key Differences

| Factor | Travel eSIM | Local SIM Card |
|---|---|---|
| Setup time | Under 5 minutes, from anywhere | 30-60 minutes at a store or kiosk |
| Purchase location | Online, before or during trip | Airport, carrier store, or convenience store |
| ID required | Typically no | Often yes (varies by country) |
| Local phone number | No (data-only) | Yes |
| Home number | Stays active (Dual SIM) | Need to swap SIMs or use Dual SIM |
| Phone compatibility | Requires eSIM-capable phone (2018+) | Works with any unlocked phone |
| Multi-country travel | Buy new eSIM per country easily | Need to buy new SIM in each country |
Country-by-Country Breakdown
The practical experience of buying a local SIM varies significantly across Latin America. Here is what to expect in the most popular destinations:
Mexico
Local SIMs are widely available in Mexico from carriers like Telcel, AT&T Mexico, and Movistar. You can buy prepaid SIMs at OXXO convenience stores, airport kiosks, and carrier shops. Prices typically start around $5-$10 for a basic data package (at time of writing). Registration may require a passport copy. Telcel has the widest coverage, particularly outside major cities. LATAM Travellers offers Mexico eSIM plans from approximately $2.59 (as of April 2026) with no store visit required.
Brazil
Brazil requires CPF (tax ID) registration for local SIM cards, which can be a hurdle for foreign tourists. Major carriers include Claro, Vivo, and TIM. Some airport locations will register a temporary number for tourists, but the process can take 30-60 minutes and availability is inconsistent. Prices for prepaid data plans start around $8-$15 (at time of writing). For travellers who want to skip the registration hassle, a Brazil eSIM from LATAM Travellers starts at approximately $3.47 (as of April 2026).
Argentina
Buying a local SIM in Argentina typically requires presenting your passport at a carrier store. Major carriers are Claro, Movistar, and Personal. Airport SIM kiosks exist at Ezeiza (EZE) but may have limited hours. Prepaid plans start around $5-$10 (at time of writing). Argentina has had periods of currency volatility, which can make local SIM pricing unpredictable for tourists. Argentina eSIM plans from LATAM Travellers start at approximately $3.47 (as of April 2026), with pricing in stable USD.
Colombia
Colombia has a relatively straightforward local SIM purchase process. Claro, Movistar, and Tigo operate the major networks. You can buy prepaid SIMs at airports, carrier stores, and some convenience shops. Registration typically requires a passport. Prices for basic data plans start around $5-$10 (at time of writing). Coverage in major cities like Bogota, Medellin, and Cartagena is generally strong. Colombia eSIM plans from LATAM Travellers start at approximately $4.11 (as of April 2026).
Costa Rica
Costa Rica SIM cards are available from Kolbi (ICE), Claro, and Movistar. Kolbi has the widest coverage, including rural and mountainous areas. You can typically buy a SIM at the airport or at carrier kiosks in shopping centres. Prices start around $5-$12 (at time of writing). Costa Rica generally does not require passport registration for prepaid SIMs. Costa Rica eSIM plans start at approximately $3.47 from LATAM Travellers (as of April 2026).
Chile
Chile has well-developed mobile infrastructure with carriers Entel, Movistar, and Claro. Prepaid SIMs are available at airports and carrier shops. Registration may require a passport. Prices for data plans start around $5-$10 (at time of writing). Chile has strong urban coverage but remote areas like Atacama may have limited signal. Chile eSIM plans from LATAM Travellers start at approximately $2.59 (as of April 2026).
Peru
Peru SIM cards from Claro, Movistar, and Bitel are available at Lima airport and carrier stores. Registration typically requires a passport. Prices start around $5-$8 for basic data (at time of writing). Coverage is strong in Lima, Cusco, and other tourist cities, but can be limited in remote Andean areas and parts of the Amazon. Peru eSIM plans start at approximately $3.47 from LATAM Travellers (as of April 2026).
When to Choose eSIM Over a Local SIM
eSIM is typically the more practical choice for most travellers to Latin America, but there are specific scenarios where a local SIM may make sense.
Choose eSIM if:
- You have an eSIM-compatible phone
- You value convenience and want to skip store visits
- You are visiting multiple countries on one trip
- You want to keep your home number active simultaneously
- You arrive late at night when airport SIM kiosks may be closed
Consider a local SIM if:
- You specifically need a local phone number (for local bookings, banking apps, etc.)
- Your phone does not support eSIM
- You are staying in one country for several months and want more affordable data

Frequently Asked Questions
Can I use both an eSIM and a local SIM at the same time?
Yes, on most modern phones. Phones with Dual SIM support (including eSIM + physical SIM) let you run both simultaneously. You can use the eSIM for data and the local SIM for calls.
Is a local SIM always cheaper than an eSIM?
No, not always. While local prepaid plans can be cheap, the total cost often increases when you factor in the SIM card purchase fee, airport markup, and time spent at the store. eSIM plans from providers like LATAM Travellers can be comparable or lower in cost for data-only usage.
Do I need a local phone number in Latin America?
Most travellers do not. WhatsApp works with your home number over data, and most hotel and restaurant bookings can be made with your existing number or email. However, some local services (banking apps, food delivery) may require a local number.
What if my phone is carrier-locked?
Contact your carrier to unlock it before travelling. Both eSIM and local SIM require an unlocked phone. Most carriers will unlock your phone for free if your contract is paid up. Check before you leave home.
