Using a local SIM card or eSIM
Buy a prepaid SIM card: You can purchase physical SIM cards from major carriers like Claro and Movistar at locations on the mainland, such as the airport.
Use an eSIM: For more convenience, an eSIM can be purchased and activated before your trip or upon arrival. This allows for instant access to local data and voice services without needing to visit a physical store.
Phone compatibility: Ensure your phone is unlocked to use a different SIM card.
Using your home carrier plan
Check international roaming: Contact your carrier beforehand to understand their international roaming policies and costs.
Be aware of costs: Roaming charges for voice and data can be exorbitant, so it's often cheaper to use Wi-Fi or a local SIM/eSIM.
Enable roaming: Make sure your phone is set up for international roaming in your device settings before you leave.
Key considerations
Coverage: Main cities have good coverage, but it can be spotty in remote areas. Check specific coverage for your destination, especially if visiting the Galapagos or the Amazon.
Unlocked phone: If you plan to use a local SIM, make sure your phone is unlocked before you travel.
Alternative options: Using Wi-Fi is widespread in hotels and many public places, which can be a free alternative to using cellular data.
