Kölbi, Liberty and Claro cover the Central Valley and both coasts on 4G; remote Osa Peninsula lodges and cloud-forest trails can weaken. Mountain roads between La Fortuna and Monteverde have brief dead zones. When you use NXTL in Costa Rica, your phone attaches to local networks such as Telefonica, Claro, Instituto Costarricense de Electricidad ICE; the live table on this page is the current list.
Setup takes minutes at home. For Costa Rica, install NXTL while you still have reliable Wi-Fi, keep your home line active for calls and bank texts, and switch on eSIM data when you land (for example via Juan Santamaría (SJO)) so you can navigate straight to San José. Top up later if you need more; unused balance stays yours.
Prepaid SIMs are sold at SJO, LIR and pharmacy chains with passport ID. Plans are tourist-friendly and often include a local number for WhatsApp hosts. NXTL is the lower-friction option for most visitors to Costa Rica. You are not shopping for a SIM in San José after a long flight — the eSIM is already on your phone, billed pay-as-you-go, with credit that carries to your next destination.
The reason travellers choose NXTL for Costa Rica — and for trips that do not stop there — is continuity. One eSIM, pay-as-you-go pricing, no expiry, and no new SIM when you leave San José for the next country. Your leftover credit is still waiting.
Rainy-season landslides can reroute buses overnight, and operators often message changes only by phone or WhatsApp. That is where NXTL helps in Costa Rica: one eSIM ready before you arrive, billed only for the data you actually use.
