UNDERSTANDING COSTS
Denmark has world-class telecom infrastructure, but calling from abroad through traditional carriers still costs a premium. Here's why international rates to Denmark remain high for many callers.
When you call Denmark from abroad, your carrier must pay Danish operators to complete the call. Denmark's major networks — TDC, Telia, and Telenor — set termination rates that international carriers pass along to you at a markup.
Denmark averages 1.3 mobile subscriptions per person — one of the highest rates in Europe. Since most Danes use mobiles rather than landlines, international callers often pay the higher mobile termination rate by default.
Major US carriers can charge $0.30 to $0.60 per minute for calls to Denmark. These rates reflect legacy pricing models and multiple intermediary hops between your carrier and the Danish network.
The number of landline connections in Denmark has fallen significantly in recent years as mobile usage continues to rise. This means fewer calls route through cheaper landline termination paths, pushing average costs higher.

OPTIONS COMPARED
From traditional phone plans to messaging apps, there are several ways to reach someone in Denmark. Each comes with trade-offs around cost, quality, and reliability.
Traditional Mobile Carrier
Major US carriers charge steep per-minute rates for calls to Denmark. Reliable connection quality, but costs add up quickly for regular callers.
International Calling Cards
Prepaid calling cards offer lower rates but require dial-in numbers and PINs. Hidden fees for connection, rounding, and maintenance can erode advertised savings.
WhatsApp / Messenger Voice Calls
Free when both parties are online, but Denmark has notably low WhatsApp adoption compared to the rest of Europe. Facebook Messenger is far more popular among Danes, meaning the person you're calling may not be reachable on WhatsApp.
VoIP Calling Services
VoIP services route calls over the internet to deliver much lower rates. Quality depends on your internet connection. Many require app installs and account setup.
Sayfone (Browser Calling)
Call any Danish landline or mobile directly from your browser at a flat 8¢/min. No app to install, no account required, and the person in Denmark doesn't need to be online — you're calling their actual phone number.
Bar lengths reflect relative cost tiers for each option — not survey percentages.
THE APP PROBLEM
Messaging apps work well when both sides are active users. But Denmark is different — Danes overwhelmingly prefer Facebook Messenger over WhatsApp, which means app-based calling often isn't an option.
With Sayfone, you call actual Danish phone numbers — landline or mobile. The person you're reaching doesn't need any app, internet connection, or account. Just their regular phone.
The problem
Unlike most of Europe, Denmark has among the lowest WhatsApp usage rates of any examined market. Danes prefer Facebook Messenger, so your WhatsApp call may never ring on the other end.
With over 70% of Danish internet users on Facebook Messenger, you'd need to be on the same platform as the person you're calling. If you use WhatsApp and they use Messenger, free calling simply doesn't work.
Messaging apps only work between users of the same app. If you need to call a Danish business, a doctor's office, a government agency, or an elderly relative with a landline, WhatsApp and Messenger calls won't connect.
Even when both parties use the same app, call quality depends on both sides having a strong internet connection. A phone call over the regular network is more reliable when the recipient is on the move or in a low-connectivity area.

Danes Are Rarely on WhatsApp
Unlike much of continental Europe, Danes mainly use Facebook Messenger. If you're trying to coordinate a call, message them on Messenger first — or just call their number directly.
Almost Everyone Speaks English
Virtually all Danish businesspeople and most of the general population speak excellent English. You won't need an interpreter for most calls.
No Area Codes Needed
Denmark uses a flat 8-digit numbering system with no area codes. Just dial +45 followed by the 8 digits — the same number works whether you're calling Copenhagen or Aalborg.
Summer Is Quiet
Most Danes take at least three weeks of vacation during summer, typically in July and August. Business calls are best scheduled outside this period.
Be Punctual
Punctuality is critical in Danish business culture. A 10 AM meeting starts at exactly 10:00. If you'll be more than 5 minutes late, call ahead immediately.
Get to the Point
Danes prefer direct, efficient communication. Keep phone calls concise, well-structured, and focused on the topic at hand. Extensive small talk is not expected.
Use First Names
Danish business culture is informal. Most Danes introduce themselves by first name only. Formal titles like Mr. or Ms. are rarely used, even in initial business interactions.
Respect Work-Life Balance
The standard Danish workweek is 37.5 hours. Avoid calling outside business hours for work matters, and don't expect replies to messages over the weekend.
