Calling Colombia from Shenzhen
Shenzhen, with a population of 12.5 million, is a major city in China 🇨🇳 with a significant community that maintains connections to Colombia . Whether you have family, friends, or business contacts in Colombia, making international calls from Shenzhen doesn't have to be expensive.
Traditional phone carriers in China charge premium rates for international calls to Colombia, often between $1.50 and $3.00 per minute. DialAnyone lets residents of Shenzhen call Colombia for as little as $0.02 per minute — saving up to 90% on every call. All you need is an internet connection and a web browser.

International Calling from Shenzhen
Shenzhen is a city of migrants, but internal ones: Mandarin speakers from Hunan, Sichuan and Henan who came for factory work in the 1990s, then engineers and designers who came for the tech industry in the 2000s, and now product managers and startup founders who treat Shenzhen's hardware ecosystem the way Silicon Valley treats software. The international calling pattern here runs along a different axis than most Chinese cities — it's less family diaspora and more business: a hardware developer on area code 755 calling a client in Germany, a PCB buyer calling from Texas, a startup's US investors checking in with their Shenzhen team.
China Unicom has a strong foothold in Shenzhen's tech-worker demographic. IDD rates from Chinese carriers are uniformly expensive for frequent professional callers; many Shenzhen tech companies buy calling solutions for their teams as a business expense rather than leaving it to personal SIMs.
Who Calls Abroad from Shenzhen
Shenzhen's outbound migration story is mostly recent and mostly professional. Engineers who left for graduate school in the United States or Germany in the 2010s are now settled there but keep close contact with former colleagues still in Nanshan and Longhua. The hardware startup scene created a particular cohort: founders who split time between Shenzhen and San Francisco, calling each direction constantly. Returned overseas students — haigui — are a significant presence inside Shenzhen itself, bringing back networks that span California, London and Singapore. There is no historic emigrant-village connection here the way Guangdong has in its rural counties; Shenzhen's diaspora ties are all new-economy, all within living memory.

Colombia has a well-developed telecommunications infrastructure, supported by several key mobile network operators. The major carriers include Claro, Movistar, and Tigo, which dominate the mobile market and offer extensive coverage across urban and rural areas. As of 2023, Colombia has made significant strides in expanding its 4G network, with over 90% of the population having access to 4G services. Additionally, 5G technology is being gradually rolled out in major cities such as Bogotá, Medellín, and Cali, promising faster data speeds and improved connectivity.
Landline services are still available but have seen a decline in usage due to the rising popularity of mobile phones. Estimates indicate that around 75% of Colombians own a mobile phone, reflecting the country's growing reliance on mobile communication. Internet penetration is also increasing, with a significant number of households accessing the internet through mobile data. The combination of widespread mobile usage and evolving technology positions Colombia as a rapidly modernizing telecommunications market.
Dialing Colombia from Abroad
To make an international call to Colombia, you'll need to follow a specific dialing format. First, dial your country's international access code (for example, 011 in the United States). Next, you will dial the country code for Colombia, which is +57. After that, you'll need to enter the area code, which typically consists of a one- to two-digit number, depending on the region (e.g., Bogotá is 1, Medellín is 4). Finally, dial the local phone number, which is usually seven digits long.
It’s important to note the distinction between calling mobile and landline numbers. Mobile numbers in Colombia typically start with a 3, whereas landlines start with the area code. There are no additional prefixes needed for mobile calls, but when calling from abroad to a landline, you must include the area code. For example, to call a mobile number in Bogotá, you would dial 011-57-3-XXXX-XXXX.
Best Times to Call Colombia from Shenzhen
Colombia operates under the Colombia Time Zone (COT), which is UTC-5. Unlike many countries, Colombia does not observe Daylight Saving Time, so the time difference remains consistent throughout the year. The typical workday in Colombia starts around 8:00 AM and ends approximately at 6:00 PM, with a lunch break from 12:00 PM to 2:00 PM.
For personal calls, evenings and weekends are usually the best times to reach someone, as many people are less busy outside of working hours. However, national holidays, such as Independence Day (July 20) and Christmas (December 25), should be avoided, as many Colombians spend these days with family. During the week, late afternoons may also be a good time, as people are winding down from work.
Calling Etiquette in Colombia
Colombian phone call etiquette varies between formal and informal situations. When answering a call, it is common to greet the caller with a friendly "Hola" (Hello), followed by your name. For more formal contexts, especially in business, it is acceptable to use "Buenos días" (Good morning), "Buenas tardes" (Good afternoon), or "Buenas noches" (Good evening) followed by your title and last name. Colombians appreciate personal relationships, so starting a conversation with small talk is often expected.
Cold calling can be perceived as intrusive, particularly in business settings, so it's advisable to establish some form of prior contact, such as an email introduction. In personal calls, people often inquire about family and well-being before diving into the main topic. In business communications, clarity and professionalism are essential, and it is common to confirm appointments or meetings through a phone call, although emails are often preferred for first contacts.
Colombia Phone Numbers: What to Expect
Colombian mobile numbers start with 3 — 300, 301, 310, 311, 315, 320, and many other 3xx codes — and no area code is needed when calling from abroad, just +57 followed by the ten-digit mobile number. Landlines are the opposite: they require an area code (1 for Bogotá, 4 for Medellín, 2 for Cali) and the local number. Rates to landlines are generally lower than to mobiles, which matters when you're calling offices or institutions regularly. Colombia has strong mobile-first habits, especially among younger urban residents, but landlines in homes — particularly older households — still exist and get answered. One thing foreign callers sometimes miss: mobile numbers are now portable in Colombia, so you can't reliably infer the operator from a 3xx prefix anymore.
Beating Carrier Rates in Shenzhen
Shenzhen's tech culture means its residents are faster than most to adopt efficient tools and slower to accept paying a carrier premium when a better option exists. Engineers here built Huawei and DJI; they are not going to dial IDD if data routing is cheaper and the call quality is comparable. The city's mobile and fiber infrastructure is world-class — Huawei's own research campuses are served by the same networks used by the general public. For frequent professional callers who ring Munich or Austin several times a week, the monthly arithmetic on carrier IDD is obvious. A per-minute VoIP rate for Germany or the US, paid only for actual call time, is simply the better business decision, and Shenzhen makes decisions that way.
Keeping Shenzhen–Colombia Call Costs Down
Colombia stays on UTC-5 all year with no daylight saving adjustment, which makes scheduling predictable from any fixed time zone. The office day typically runs 8 AM to 6 PM, with lunch from noon to 2 PM — calling during that midday window gets you voicemail more often than a person. Morning calls before noon tend to have the best pickup rates for business contacts. For personal calls, evenings after 7 PM are the norm. Colombia has a large number of public holidays — more than most Latin American countries — so check the calendar before scheduling; Semana Santa (Holy Week before Easter) essentially empties offices. If a contact doesn't answer on a first try, sending a WhatsApp message is standard practice and more likely to prompt a callback than voicemail.
