Getting a local SIM card recommended
Especially when you are like us and work online, Internet while traveling can be a struggle sometimes, in Costa Rica, Internet Access is usually not bad, and most places (like cafes & restaurants) offer wifi.
We anyway recommend buying a local SIM card upon arrival. We use a SIM card from Kolbi and find it the one with the best reception in most parts of the country. You can recharge your SIM card from your phone, which is very convenient. We pay 4000 Colones (6-7$) for 2 GB.
