Colombia has five active mobile network operators serving a mobile subscriber base of over 60 million connections. All major networks are supported by Remindavo. Colombian mobile numbers are 10 digits, starting with 3, and require no leading zero adjustment for international dialing.
Colombia's largest mobile network operator with approximately 38% of the subscriber market. Claro Colombia is the Colombian subsidiary of América Móvil, the Mexican telecommunications giant controlled by Carlos Slim Helú, which operates Claro-branded networks across 17 Latin American countries. Claro Colombia offers the most pervasive national coverage, including rural coverage in the Andean highlands, the Caribbean and Pacific coasts, the Llanos, and remote Amazonian departments. Claro operates across 2G, 3G, 4G LTE, and 5G bands in major cities. Enter your Claro Colombia number as +57 3XX XXX XXXX.
Colombia's second-largest mobile operator with approximately 25% market share. Movistar Colombia is operated by Telefónica, the Spanish telecommunications company that runs Movistar-branded services across Spain and Latin America. Movistar Colombia has strong coverage in major urban centres — Bogotá, Medellín, Cali, Barranquilla, Cartagena, Bucaramanga, and Manizales — and a well-developed 4G LTE network. Enter your Movistar Colombia number as +57 3XX XXX XXXX.
Colombia's third-largest mobile operator with approximately 20% market share. Tigo Colombia is operated by Millicom International Cellular, a Luxembourg-based company that runs Tigo-branded networks across several Latin American and African markets. Tigo has a particularly strong presence in Colombia's major cities and is known for competitive pricing and bundled mobile-broadband offerings. Enter your Tigo Colombia number as +57 3XX XXX XXXX.
A newer entrant to the Colombian market, WOM Colombia launched commercial services around 2021 after acquiring spectrum in a government auction. WOM operates on a disruptive pricing model — similar to its parent WOM brand in Chile — targeting urban consumers with low-cost unlimited data plans. WOM has deployed 4G LTE infrastructure primarily in Bogotá, Medellín, Cali, Barranquilla, and other major cities, with ongoing network expansion. Enter your WOM Colombia number as +57 3XX XXX XXXX.
ETB is a smaller mobile operator primarily serving Bogotá and the surrounding Cundinamarca department. ETB is a public utility company owned by the District of Bogotá and is one of the oldest telecommunications companies in Colombia, originally founded as a telephone company in 1884. ETB offers mobile services as part of a broader telecoms portfolio that includes fixed-line, broadband, and corporate services primarily in the capital region. Enter your ETB mobile number as +57 3XX XXX XXXX.
Colombia operates on a single, permanent time zone: Colombia Time (COT), UTC-5. Colombia has never observed daylight saving time — COT remains fixed at UTC-5 throughout the year, regardless of the season. This is consistent across all Colombian territory: the Andean highlands (Bogotá, Medellín, Manizales, Pereira), the Caribbean coast (Barranquilla, Cartagena, Santa Marta), the Pacific coast (Buenaventura, Tumaco), the Llanos Orientales, and the Amazonian departments all share the same COT offset.
This creates an interesting calendar dynamic for Colombian professionals working with international counterparts:
No DST means no scheduling surprises: Because Colombia never adjusts its clocks, Remindavo never needs to recalculate reminder times for seasonal clock changes. A meeting set for 09:00 COT on March 1 and the same meeting on September 1 both receive their reminder calls at exactly 09:00 COT local time. The gap to US partners may shift by one hour in spring and fall — but the Colombian side of the schedule is always stable.
All Colombia mobile numbers are 10 digits and start with 3 — for example, 310 123 4567 or 320 987 6543. Unlike some countries where a leading zero must be dropped for international dialing, Colombian mobile numbers have no leading zero. To enter your Colombian number in Remindavo, simply add the country code +57 before the full 10-digit number:
To dial a Colombian mobile number from abroad, dial your country's international exit code (00 or 009 from some countries, 011 from the US) followed by 57 and the 10-digit number. Remindavo places an immediate test call to your number when you add it, so you can confirm delivery on your specific carrier and prefix before any reminders are scheduled.
Remindavo connects to Google Calendar and Microsoft Outlook — both widely used by professionals across Colombia's diverse economy. Setup takes under 60 seconds:
Because Colombia uses a fixed UTC-5 offset with no DST, Remindavo never needs to adjust for seasonal clock changes on the Colombian side. A meeting at 10:00 COT in January and the same meeting in July both receive their reminder calls at exactly the right local time.
Colombia has emerged as one of Latin America's most dynamic economies, anchored by two distinct metropolitan powerhouses with very different profiles.
Bogotá is Latin America's third-largest city by metro population (11 million+), sitting at 2,600 metres above sea level on the Sabana de Bogotá plateau. It is Colombia's financial, legal, and governmental centre. The city houses the headquarters of Colombia's major banks (Bancolombia, Davivienda, Banco de Bogotá, BBVA Colombia, Grupo Aval), multinational regional offices, law firms, and consulting practices. Corporate culture in Bogotá — and across Colombia generally — places high value on formal titles and professional courtesy: addressing contacts as "doctor," "licenciado," or "ingeniero" is standard in business correspondence and meetings.
Bogotá is also the centre of Colombia's growing technology and startup ecosystem, with investment flowing into fintech, healthtech, agritech, and logistics platforms. Nequi, the mobile banking platform launched by Bancolombia, has become one of the most downloaded financial apps in Colombia. The broader Colombian fintech sector has attracted significant international venture capital, connecting Bogotá-based founders with investors in Miami, New York, London, and Madrid on cross-timezone calls that benefit from reliable reminder infrastructure.
Medellín's transformation from one of the world's most dangerous cities in the late 1980s and 1990s to a celebrated innovation hub is one of the most striking urban turnarounds of the 21st century. The city won the prestigious Lee Kuan Yew World City Prize in 2016 — the first Latin American city to do so — in recognition of its urban innovation programmes: the aerial cable car system (Metrocable) connecting hillside comunas to the Metro network, the escalator system in the steep Comunas 13, and the network of public libraries and learning centres (parques biblioteca) distributed across historically underserved neighbourhoods.
Ruta-N, the city's technology and innovation hub, anchors a growing cluster of technology companies, startups, and co-working spaces in the northern zone of Medellín. The city has actively recruited international technology companies to establish Latin American headquarters or nearshore development centres, and has produced a generation of Colombian tech founders who commute between Medellín and San Francisco, New York, and Madrid. The "Medelltec" brand — a portmanteau of Medellín and technology — is used by city government and the innovation community to market the ecosystem internationally.
Two Colombian export sectors make scheduling precision particularly valuable:
Colombia is the world's third-largest coffee producer and the largest producer of washed Arabica coffee — the premium grade used by specialty roasters and major chains worldwide. The coffee supply chain runs from fincas (farms) in the Coffee Triangle (Eje Cafetero: Caldas, Risaralda, and Quindío departments, plus Antioquia, Huila, and Nariño) through the Federación Nacional de Cafeteros (FNC/Juan Valdez) cooperative system to export contracts with buyers in the US, Europe, and Japan. Export contract negotiations, quality cupping sessions, shipping vessel booking windows, and FNC price committee calls all occur on fixed schedules where a missed meeting has commercial consequences. The COT time zone places Colombia conveniently between European morning and US morning schedules — a 09:00 COT call is 14:00–15:00 in London and 09:00–12:00 across US time zones — making Colombia a natural bridge timezone for transatlantic commodity trading calls.
Colombia is the world's second-largest flower exporter after the Netherlands, supplying approximately 75% of the flowers sold in the United States market. The flower industry is centred in the Bogotá savanna (Sabana de Bogotá) and the Rionegro plateau in Antioquia, where the altitude and climate produce ideal year-round growing conditions. Colombia exports roses, carnations, chrysanthemums, and tropical flowers primarily through El Dorado International Airport in Bogotá — the airport that handles more international freight than any other in Latin America by volume of perishables.
The flower export calendar has two critical peaks: Valentine's Day (February 14) and Mother's Day (second Sunday of May in the US). In the weeks before each peak, Colombian flower exporters manage an intense schedule of harvest timing calls, cold chain coordination, airfreight booking confirmations, and customs clearance appointments where a missed call can mean a delayed shipment — and cut flowers that arrive after Valentine's Day have essentially zero market value. The compressed timelines around these peaks make phone call reminders for scheduled coordination calls particularly valuable for the logistics managers, export coordinators, and air cargo brokers who manage the supply chain.
Colombia's telecommunications sector is regulated by the CRC (Comisión de Regulación de Comunicaciones), the independent regulatory body that oversees spectrum allocation, interconnection, and consumer protection rules for mobile and fixed-line operators. The CRC works alongside the Ministry of Information Technologies and Communications (MinTIC, Ministerio de Tecnologías de la Información y las Comunicaciones).
Personal data protection in Colombia is governed by Law 1581 of 2012 (Ley Estatutaria de Protección de Datos Personales, commonly known as the Habeas Data law), implemented by Decree 1377 of 2013. The law was developed with reference to international data protection standards including the OECD Privacy Guidelines and the EU Data Protection Directive that preceded GDPR — making it conceptually aligned with, though predating, the EU's General Data Protection Regulation. The supervisory authority is the SIC (Superintendencia de Industria y Comercio), which handles data protection complaints, investigations, and sanctions.
Key principles under Law 1581 include purpose limitation (data may only be collected for specified, explicit purposes), proportionality (only data necessary for the stated purpose may be collected), and consent (data subjects must provide informed consent for data processing). Remindavo's data practices are built around these principles: the service collects only your name, email address, mobile number, and calendar event metadata (times and titles). Remindavo does not record call audio, does not sell personal data to third parties, and does not retain calendar data beyond scheduling requirements. Data deletion requests are handled at [email protected].
Yes. Remindavo delivers phone call reminders to Claro Colombia (América Móvil) mobile numbers across all prefix ranges. Claro is Colombia's largest MNO with approximately 38% market share and the broadest national coverage including rural areas. Enter your Claro number as +57 followed by your full 10-digit number (e.g., +57 310 123 4567). Remindavo places an immediate test call to confirm delivery before any reminders are scheduled.
Yes. Remindavo supports Movistar Colombia (Telefónica, ~25% market share), Tigo (Millicom, ~20%), WOM Colombia (urban focus, competitive pricing), and ETB (Empresa de Telecomunicaciones de Bogotá, primarily serving Bogotá). All Colombian mobile numbers follow the same format: 10 digits starting with 3, entered as +57 3XX XXX XXXX. The immediate test call placed when you add your number confirms delivery on your specific carrier.
Colombia uses Colombia Time (COT), UTC-5, year-round with no daylight saving time. COT is fixed permanently — Colombia has never observed DST. Remindavo automatically applies COT to your calendar events. Because the offset never changes, a meeting at 09:00 COT in January and the same meeting in August both receive their reminder calls at exactly the right local time, with no seasonal adjustment needed.
Colombian mobile numbers are 10 digits and start with 3 — there is no leading zero to drop. Add +57 before the full number: 310 123 4567 becomes +57 310 123 4567. This format works for all Colombian carriers — Claro, Movistar, Tigo, WOM, and ETB. Remindavo places an immediate test call when you add your number to confirm delivery.
Yes. Google Calendar is widely used across Colombia's technology sector (Bogotá startup ecosystem, Medellín's Ruta-N hub), financial services (Bancolombia, Davivienda, Grupo Aval), export industries (coffee, flowers), and professional services. Connect your Google Calendar to Remindavo and all events generate a phone call reminder at your chosen lead time before each one starts. Microsoft Outlook is equally supported.
Remindavo is built with data minimisation as a core principle aligned with Law 1581 of 2012 (Habeas Data) and Decree 1377 of 2013. The service collects only what is needed to deliver call reminders: name, email, mobile number, and calendar event metadata. Remindavo does not record calls, does not sell personal data, and does not retain calendar data beyond scheduling requirements. The supervisory authority for data protection in Colombia is the SIC (Superintendencia de Industria y Comercio). Data deletion requests are handled at [email protected].
Set up in 60 seconds. Remindavo calls your Claro, Movistar, Tigo, or WOM number before every calendar event — no notification to swipe away.
