Calling a landline in Japan from your laptop costs 7.5 times more than calling a landline in the UK — and most people have no idea why. VoIP international rates aren't random. They're built from a stack of real costs that carriers pass on to you, sometimes transparently, often not. This article breaks down exactly how those rates get calculated, what drives the differences between countries, and how to spot a fair deal from a padded one.
Key Takeaways
- Landline termination fees vary by country — Japan charges roughly $0.10–$0.12/min just to deliver the call, before any provider markup
- Mobile vs. landline is the single biggest rate split: calling a mobile in Nigeria can cost 3–5× more than a Nigerian landline
- Providers that charge per-second billing save you 15–20% versus per-minute rounding on short calls

Why Landline Calls Cost More Than App-to-App Calls
The gap is stark. A WhatsApp call to a friend costs nothing. A VoIP call to a landline in Germany costs $0.04/min. That difference exists because landline calls leave the internet entirely — they have to terminate on the public switched telephone network (PSTN), and that costs real money.
When you call a landline through any VoIP provider, your voice travels as data packets across the internet to a gateway near the destination country. At that point, it converts to a traditional phone signal and rides the local carrier's infrastructure to ring an actual physical line. That last leg — called "termination" — is what you're paying for. The PSTN operator charges the VoIP provider, and the VoIP provider charges you.
App-to-app calls (think two people on the same platform) never touch the PSTN. No termination fee. No carrier. Hence, free.
The Four Cost Layers Inside Every International VoIP Rate
Every per-minute rate you see is actually four costs bundled together, usually without any breakdown shown to you.
1. Termination fees. These are set by the destination country's telecom operators, regulated (or not) by local governments. The UK's Ofcom keeps landline termination rates low — around $0.001–$0.003/min. Japan's NTT charges dramatically more, which is why calling Japan at $0.15/min is standard industry-wide, not a rip-off by any specific provider.
2. Interconnect and transit costs. Getting your voice data from your browser to a gateway in the right country costs money — routing, infrastructure, redundancy. Providers with more points of presence spend less per minute here. Smaller providers often resell capacity from larger wholesale carriers, adding a margin on top.
3. Provider margin. This is where the variation gets wild. A margin of 20–40% over wholesale cost is common. Some consumer apps charge 300% over wholesale on popular routes like the USA or UK, banking on users not comparing rates.
4. Platform and compliance costs. Number masking, caller ID services, fraud prevention, regulatory compliance in each country — these get baked into per-minute pricing too. For business VoIP with features like local numbers in 100+ countries, these costs are real and justified.
Why Some Countries Are Just Expensive to Call
Your VoIP provider doesn't control termination fees. They're set by the destination country's telecom market, and some markets are simply pricier.
Nigeria's landline rate sits at $0.33/min on most providers, including GlobCall. The Philippines is $0.46/min. These aren't exploitative markups — they reflect high wholesale termination costs in markets where PSTN infrastructure is less commoditized and sometimes monopolized by state-linked carriers.
Compare that to calls to the USA at $0.02/min or calls to the UK at $0.03/min. Both countries have hyper-competitive carrier markets that drove termination fees to near-zero over the past decade.

The general rule: more telecom competition in a country means lower landline rates for you.
Mobile vs. Landline: The Rate Split Nobody Warns You About
Calling a landline and calling a mobile in the same country are often priced completely differently — sometimes 2–5× apart. In markets where mobile termination rates are deregulated or where carriers charge a premium for mobile delivery, you'll pay significantly more to reach a cell phone than a fixed line.
Australia is a good example. Calling an Australian landline runs about $0.05/min. Australian mobile rates with most providers are noticeably higher. The split happens because Australian mobile carriers charge higher termination fees than fixed-line operators — the same structural reason Japan's rates are high applies here at the mobile level.
Before you call, check whether the number you're dialing starts with a mobile prefix. In the UK, 07 numbers are mobile. In India, 10-digit numbers starting with 7, 8, or 9 are mobile. Dialing the wrong type without knowing the rate difference can quietly double your bill.
Per-Minute vs. Per-Second Billing: The Hidden Math
Two providers can quote the same rate but deliver very different actual costs. The billing increment is why.
Per-minute billing rounds every call up to the next full minute. A 90-second call gets billed as 2 minutes. A 3-minute-10-second call gets billed as 4 minutes. On short calls — which make up a large share of real call behavior — you're routinely paying 20–40% more than the quoted rate implies.
Per-second billing charges you for exactly what you use. 90 seconds = 1.5 minutes of cost. That's it.
On high-frequency call volumes, the difference adds up fast. A team making 50 short calls a day at $0.05/min with per-minute rounding might pay 25% more than the same team on per-second billing. Always check the billing increment before committing to any VoIP plan.

What "Shared Balance" Actually Means for Business Calling Costs
For businesses, the pricing model matters as much as the per-minute rate.
Most traditional business phone systems charge per seat — you pay monthly for each user whether they make calls or not. A 10-person team with 4 active callers still pays for 10 seats. That's a structural waste built into the pricing model.
Shared balance means the whole team draws from one credit pool. No per-seat fees. A team of 20 people making calls to India at $0.08/min or Mexico at $0.03/min pays only for actual call minutes, split across everyone. If three people are heavy callers and the rest make occasional calls, you're not subsidizing idle seats.
For growing teams, this compounds fast. The pay-as-you-go vs. monthly subscription FAQ walks through exactly when each model makes financial sense. For international-heavy teams, pay-as-you-go shared balance almost always wins.
Frequently Asked Questions
Why do landline rates differ so much between countries?
Termination fees are set by destination-country carriers and regulators, not by your VoIP provider. Countries with competitive telecom markets (USA, UK, Germany) have near-zero termination fees. Countries with less competition or state-linked carriers (Philippines, Nigeria) have much higher ones, which flows directly into your per-minute cost.
Is it cheaper to call a landline or a mobile internationally?
Landlines are almost always cheaper. Mobile termination rates in most countries are higher than fixed-line rates, sometimes 2–5× more. Before calling, check whether the number you're dialing is a mobile or fixed line — the prefix usually tells you, and the international calling rates FAQ covers common country formats.
Why did my call cost more than the advertised rate?
Most likely: per-minute billing rounding, a connection fee (some providers charge $0.01–$0.05 per call regardless of duration), or you called a mobile number at a different rate than the landline rate you were comparing. Always check whether the rate shown applies to landlines specifically and whether there's a connection fee.
Do VoIP landline rates change frequently?
Yes. Wholesale termination fees are renegotiated between carriers periodically, and currency fluctuations affect rates in some markets. Major route changes (USA, UK, Europe) are rare — those markets are stable. Emerging market routes can shift more. Providers that publish their rates publicly, like GlobCall's rates page, make it easier to track.
Can I call landlines from a browser without downloading anything?
Yes. Browser-based VoIP has been fully viable since WebRTC became standard. No app, no plugin, no SIM card required. GlobCall's guide on calling internationally from a browser covers exactly how it works and what you need.
The Bottom Line
VoIP landline rates aren't arbitrary. Every number you see is the sum of real, traceable costs:
- Termination fees set by destination-country carriers — the biggest variable
- Transit and interconnect costs that favor providers with wider infrastructure
- Provider margin — where the most consumer-unfriendly pricing usually hides
- Billing increments — per-second vs. per-minute can shift your real cost by 20%+
- Mobile vs. landline split — always check what type of number you're calling
The providers that show you clean, per-destination rates with no connection fees and per-second billing are playing it straight. The ones burying the math in asterisks usually aren't.
