I am new to Expat.com but I have been researching retiring in Costa Rica since February 2020. My wife and I will be returning in May for 3 weeks to file for our pensionado residency and more closely fine tune the area that we will rent a house in next June. We will be living on one of the ridges above Grecia and want to find the best area and micro climate for our new life.
Previously we have driven over 1800Km covering almost half of the country without any time doing 'touristy stuff. Given the issues with cellphone coverage using Claro, through our carrier in the US on our last trip, I intend to purchase a local SIM card for my unlocked phone. Can anyone tell me their thoughts on what carrier offers the best coverage (not necessarily price) particularly in the Central Valley for this trip? Particularly in the Grecia/Atenas/Alajuela area.
