International Calling from Seongnam
Seongnam sits just south of Seoul, close enough that Bundang-gu is commonly treated as an extension of the capital's tech and business corridor.판교 (Pangyo) Techno Valley sits inside the city limits, home to Korean branches of global firms and a dense cluster of domestic IT companies. The people calling internationally from here tend to be white-collar: developers with colleagues in San Francisco or Berlin, product managers on calls with US clients, startup founders maintaining investor relationships across time zones.
That professional pattern runs alongside a residential one. Seongnam is a mature commuter city with one of the higher median incomes in Gyeonggi Province, and many households have family members who studied abroad and stayed. Calls flow steadily to the US, Canada, Australia, and Germany. Korean carrier monthly plans bundle domestic calls generously but bill international destinations separately, either via per-minute rates or add-ons that cover a fixed country list — an awkward structure for anyone keeping in touch with people across multiple countries.
Seongnam's International Communities
The Pangyo tech cluster pulls engineers and researchers from China and the US on long-term work assignments, and that cycle of arrivals and departures generates its own calling traffic: people staying in Seongnam long-term who still ring family in Beijing, Shanghai, or the Bay Area. Korean-Americans returning to work in the Korean tech industry — a pattern common since the 2010s — maintain strong US ties from Bundang apartments. Chinese students and researchers studying at nearby universities form another corridor, calling parents in Sichuan and Guangdong most evenings. Seongnam itself sends its own graduates outward: medical students who matched at US hospitals, engineers on secondment to European facilities, and younger residents on working-holiday visas in Australia.

Telecommunications in Costa Rica
Costa Rica has a robust telecommunications infrastructure that supports both mobile and landline services. The country is serviced primarily by two major mobile network operators: Instituto Costarricense de Electricidad (ICE), which operates under the brand name Kolbi, and Claro, a subsidiary of América Móvil. Both companies provide extensive 4G coverage across most urban areas, with ICE also rolling out 5G services in select regions, particularly in San José. As of late 2023, mobile phone penetration in Costa Rica is impressive, with over 150% of the population subscribed to mobile services, indicating that many individuals use multiple SIM cards or devices. Landline usage remains prevalent, especially in business environments, although mobile phones have largely overtaken landlines in personal use. The country has made significant investments in expanding its telecommunications network, resulting in improved connectivity and internet access throughout both urban and rural areas.
Dialing Costa Rica from Abroad
To make an international phone call to Costa Rica, you'll need to follow a specific dialing format. Start by dialing your country's international exit code, followed by Costa Rica's country code, which is +506. The complete dialing sequence looks like this: Exit Code + 506 + Local Number. Costa Rica does not have area codes; instead, all local numbers are 8 digits long. It’s important to note that the dialing format for mobile and landline numbers remains the same. However, if you are calling from within Costa Rica, you would omit the country code and simply dial the 8-digit number. There are no special prefixes required for mobile or landline calls. Keep in mind that international calling rates can vary significantly depending on your service provider, so it’s advisable to check their rates prior to making a call.
Best Times to Call Costa Rica from Seongnam
Costa Rica operates on Central Standard Time (CST), which is UTC-6. Unlike many countries, Costa Rica does not observe Daylight Saving Time, making it consistent year-round. The typical workday in Costa Rica runs from 8:00 AM to 5:00 PM, Monday through Friday. However, many businesses may start as early as 7:00 AM. For personal calls, evenings and weekends are generally more suitable, as most people are off work and more relaxed. It is advisable to avoid calling during lunch hours (generally between 12:00 PM and 1:30 PM) or on national holidays when most businesses are closed. Key holidays include New Year’s Day (January 1), Independence Day (September 15), and Christmas (December 25). Being mindful of these timeframes can enhance your communication effectiveness.
Calling Etiquette in Costa Rica
Costa Ricans, known as "Ticos," generally have a warm and friendly communication style. When answering the phone, it is customary to greet the caller with "¿Aló?" or "Hola," followed by your name. A formal greeting may include "Buenos días," "Buenas tardes," or "Buenas noches," depending on the time of day. Cold calling is less common and often perceived as intrusive, so it's advisable to introduce yourself clearly and state your purpose for calling right away. In business settings, a more formal approach is typical, with polite language and a respectful tone. Personal calls allow for a more relaxed style, but it is still important to show courtesy. Preferred communication channels may vary, with some individuals favoring WhatsApp or other messaging apps for quick exchanges, while emails and phone calls are preferred for more formal discussions.
Mobile vs Landline Numbers in Costa Rica
Costa Rica moved to eight-digit numbers without area codes in 2008, and that flat eight-digit structure applies to both mobile and landline. The first digit is the reliable distinguisher: numbers starting with 8 or 6 are mobile; numbers starting with 2 are landlines. That rule is consistent and well-established, so a number beginning with 2 is almost certainly a fixed line — a home, office, or business. Mobiles starting with 8 dominate personal communication. ICE (Kolbi) and Claro are the main operators, and mobile coverage across the Central Valley and the Pacific coast is generally solid. More remote areas of the Nicoya Peninsula and parts of the Caribbean coast can have weaker signal, which means dropped calls are a genuine possibility rather than a wrong number.
Why Seongnam Callers Switch to VoIP
High-speed internet in Bundang-gu and Sujeong-gu is close to ubiquitous — fiber connections in apartment blocks here are fast enough to run video calls without a stutter. The problem has never been bandwidth. It's that Korean carriers treat international minutes as premium inventory, separate from the flat-rate domestic plans that make local calling cost nothing. Someone calling a US mobile number from a Seongnam apartment on a standard SKT or KT plan is paying international per-minute rates that bear no relationship to what the call actually costs to route. Tech-aware residents figured this out early: VoIP over fiber or LTE is simply another way to use infrastructure they're already paying for, at a price set by competition rather than by the carrier's international billing desk.
Cost-Saving Habits for Calling Costa Rica
Costa Rica holds UTC-6 all year — no daylight saving — which makes it permanently aligned with US Central Standard Time and six hours behind UTC. From Europe, the gap is wide; from the US East Coast, it's manageable at three hours. Business hours run roughly 8 AM to 5 PM, but the lunch break from noon to 1:30 PM is real and observed. Mornings before noon tend to be the most productive calling window. Rates to Costa Rican landlines (2-prefix numbers) are typically lower than to mobiles, so for long calls to offices or known home lines, that prefix is worth keeping. The two weeks surrounding September 15 (Independence Day) slow business activity considerably, and the weeks before Easter — Semana Santa — see families leave San José for the beach; personal reachability drops sharply during both periods.
