An Ecuadorian mobile number is a key for one-time passwords. Banks and many delivery apps expect a local line once you open dollars accounts or sign a lease, and opening a bank account often stalls without one. The first legal line is a shop visit in your own name, not a street stall SIM already registered to someone else.
What do you take to the counter?
Go to a branded Claro, Movistar, or CNT store in Quito, Cuenca, Guayaquil, or the city where you will stay. Mariscal Sucre (UIO) and José Joaquín de Olmedo (GYE) sometimes keep kiosks, but city centres usually price better packs. Take your physical passport. Claro's tourist page tells you to say you want to activate a Claro Chip with a passport. Its published Claro Chip welcome pack lists about $4 including taxes, with a short free data and WhatsApp promotion that lasts a few days; confirm the full first payment and data allowance at the desk before you pay.
Claro also documents an email path: send a passport photo and details to activacionpasaporte@claro.com.ec, wait for confirmation, then dial *611 to finish activation. Movistar and CNT sell prepaid too, yet passport steps vary by branch, so treat the desk quote as the source of truth. Stay until the SIM places a call or loads data before you leave.
English works in some tourist-facing shops in Quito and Cuenca, yet forms and SMS may still arrive in Spanish. If paperwork stalls, the same pattern shows up in bureaucracy without Spanish.
Prepaid first, longer plans later
Start on prepaid in US dollars. Top up with operator apps, recharge cards at Supermaxi or pharmacies, or branch credit. Visitor lines follow the stay window the shop copied. Ask how long the pack stays active and renew only through the same operator. A line registered to you can be recharged. A line registered to a stranger cannot.
Claro sells prepaid eSIM online for compatible phones, but approval and activation can take business hours, and many visitors still finish identity checks in a store. Do not assume an airport eSIM desk replaces passport registration. Home broadband and bus cards are separate contracts; compare them with utilities, internet, and transport after the phone line exists.
What works before the store opens?
Landing late, or landing when the arrivals counter is shut, leaves you without an Ecuadorian number for the ride into the city. If you want data before an Ecuadorian prepaid SIM is registered, an eSIM for the first days covers the airport and the trip to a branded store.
That travel eSIM is not your Ecuadorian mobile number. It will not receive the bank texts that expect a local line. Use it until the store finishes registration, then keep the Ecuadorian SIM in the phone. Where you sleep while you finish the shop visit still matters for address proof later: How to rent a home and Where to live in Ecuador. Residence and cédula steps also need a reachable contact: Apply for a residence permit and Get a cédula.
Common misconceptions
One misconception is that any kiosk in arrivals can legally register a SIM to your passport. Use a branded Claro, Movistar, or CNT counter, and refuse a SIM that is already active in another name.
Another is that a foreign roaming SIM is enough for Ecuadorian banking. Branches still ask for a local number for OTPs, and many apps reject foreign MSISDNs for signup.
Summary
Get a prepaid SIM in your own name at a branded store, with your passport and a completed activation (desk or Claro's published email path).
Use a travel eSIM only for the hours before that shop visit. Keep the Ecuadorian number for bank texts, and move to a longer plan after your address and residence path are clearer.
