Surabaya and the World
Surabaya is East Java's commercial engine, and its phone habits reflect a trading city rather than an administrative one. Merchants in the Ampel and Pabean districts have kept lines open to Chinese and Arab suppliers for generations, so international calling is not a novelty — it's a cost of doing business. Telkomsel dominates the postpaid market, but most residents top up prepaid credit in small denominations from corner warung stalls, and international rates on that model can chew through a balance faster than a local call ever would.
The city also sends workers abroad in large numbers. East Java contributes heavily to Indonesia's migrant labor outflows toward Saudi Arabia, Malaysia and South Korea, and many of those workers trace back to Surabaya or the towns that look to it as a hub. Families in Wonokromo or Rungkut waiting for a call from Riyadh or Kuala Lumpur understand very well what per-minute charges feel like when the overseas party is the one dialing.
Surabaya's International Communities
The Arab-Indonesian community of Kampung Arab near Surabaya's Ampel mosque has maintained ties to Hadhramaut in Yemen for well over a century, one of Indonesia's longest-running international calling corridors. A substantial Chinese-Indonesian business community keeps active connections to mainland China, particularly for textile and electronics sourcing. Among regular working families, Saudi Arabia and Malaysia are the two most common destinations for labor migration out of East Java, meaning calls in both directions — the worker calling home, the family calling to check in — are routine weekly events. A smaller but growing stream of Surabayan graduates has started appearing in Australian and South Korean universities.

Slovenia boasts a well-developed telecommunications infrastructure, characterized by a competitive market and high-quality services. The major mobile network operators include Telekom Slovenije, A1 Slovenia, and Telemach, all offering extensive coverage across the country. As of 2023, Slovenia has made significant advancements in mobile technology, with 4G coverage reaching approximately 99% of the population and ongoing developments in 5G technology. The deployment of 5G networks is expanding, targeting urban areas primarily in cities like Ljubljana, Maribor, and Celje.
Landline services are still prevalent, with a good number of households maintaining fixed-line connections, although mobile phone usage is predominant. Mobile phones are widely used, with around 90% of the population owning a smartphone. The integration of mobile services with high-speed internet has fostered a culture of connectivity, making it easy to stay in touch with friends, family, and business associates.
Dialing Slovenia from Abroad
To call Slovenia from abroad, you need to follow a specific dialing format. Start by dialing your country’s international access code, which varies by country (for example, 011 for the US, 00 for many European countries). Next, enter Slovenia's country code, which is +386. After this, dial the area code (without the leading zero) followed by the local number.
Slovenia’s area codes vary by region, such as 1 for Ljubljana, 2 for Maribor, and 3 for Celje. If you are calling a mobile phone, simply dial the mobile number, which usually starts with a digit 6 or 7. There are no special prefixes required for mobile numbers versus landline numbers aside from the initial area code. The entire structure ensures smooth connectivity, allowing callers to reach anyone in Slovenia efficiently.
Best Times to Call Slovenia from Surabaya
Slovenia is in the Central European Time Zone (CET), which is UTC+1, and observes Daylight Saving Time (CEST) during the summer months, moving to UTC+2. The typical workday runs from 8 AM to 4 PM, making these hours the best time to reach business contacts. However, it’s essential to consider the lunch break, which usually occurs around noon and can last until 1 PM.
Evenings, particularly between 5 PM and 8 PM, are generally good for personal calls as many people are home and available. Weekends can vary; while some may be free for casual conversations, others may be occupied with family activities. Additionally, it's wise to avoid calling during national holidays, such as Independence Day (June 25) or Christmas (December 25), when many people will be unreachable.
Calling Etiquette in Slovenia
In Slovenia, phone call etiquette reflects a blend of formal and informal styles. When answering a call, people typically greet with a friendly "Dober dan" (Good day) or "Halo" (Hello). In business contexts, it is common to introduce oneself and state the purpose of the call clearly. In social situations, a casual greeting may suffice, but politeness is always appreciated.
Cold calling is generally acceptable, especially in business contexts, but the approach should be respectful and concise. Slovenes tend to value punctuality and directness during conversations. When it comes to personal calls, people may prefer messaging apps like WhatsApp or Viber, especially among younger individuals. Overall, a respectful tone and clarity in communication are key to ensuring positive interactions.
Mobile vs Landline Numbers in Slovenia
Slovenian mobile numbers begin with 6 or 7 after the country code, which is a clean signal that lets you identify the line type immediately. Landlines carry area codes: 1 for Ljubljana, 2 for Maribor, 3 for Celje, and further regional codes for the rest of the country. The gap between them in daily usage is real — mobiles are where people are reachable, landlines are where businesses have a stable listed presence. One practical note: Slovenia is a small country where a significant share of the population uses Viber alongside standard calls; if you are trying to reach a personal contact who is not answering an international call from an unknown number, a Viber message often produces a faster response than repeated calling. Business lines answer reliably during hours, so the mobile-vs-landline distinction matters most for personal contacts.
Why Surabaya Callers Switch to VoIP
Surabaya's prepaid-heavy phone culture means most residents never signed a contract that includes international minutes. The options available — dialing an IDD prefix at carrier rates, finding an international calling card at a stall near the Gubeng railway station, or asking the person abroad to call back — all put the cost somewhere awkward. Calling cards in particular carry the familiar East Java markup: the face value looks reasonable until you subtract the access fee and the connection charge. Mobile data, which Surabayans buy routinely in 10GB or 20GB top-up bundles, can carry a voice call to Riyadh or Kuala Lumpur without touching the carrier's international pricing. The call lands on the recipient's ordinary phone number, and the rate per minute is known before dialing.
Cost-Saving Habits for Calling Slovenia
Ljubljana landlines and other geographic numbers typically cost less to reach than Slovenian mobiles, and since most businesses maintain fixed numbers, using those for longer conversations makes sense. Slovenia runs on CET in winter and CEST in summer, in step with Central Europe broadly. The working day starts at 8 AM and wraps by 4 PM in many offices — earlier than the Western European norm — so morning calls from North America need to be quite early to catch the business window. June 25, Independence and Unity Day, is a major national holiday; the country effectively pauses. The summer period from late July through August sees many Slovenes on holiday, particularly around the Adriatic coast, making both offices and personal contacts harder to reach consistently. September is when the pace picks back up and callbacks become more reliable.
