Calling the USA from the UK costs most people far more than it should. With a standard UK mobile carrier add-on, you're typically paying 3p–5p per minute at best — and often much more if you're not on a roaming bundle. Here's the short version: you can call any US number for $0.02 per minute using browser-based VoIP, no app download, no SIM swap, no monthly contract. This article shows you exactly how, what the real costs look like compared to your alternatives, and where the hidden fees tend to hide.
Key Takeaways:
- Browser-based VoIP services like GlobCall let you call US numbers from the UK for as little as $0.02/min — that's roughly 1.6p at current exchange rates.
- You don't need a new SIM, a downloaded app, or a monthly subscription to get this rate.
- Carrier add-ons from EE, Three, and O2 often look cheaper than they are once you factor in activation fees, bundle minimums, and per-call connection charges.

Why UK-to-USA Calls Are Still Expensive in 2026
Most UK carriers haven't dropped international rates the way they've dropped domestic ones. The wholesale cost of terminating a call on a US number is genuinely low — around $0.002–$0.005 per minute at the network level — but what you pay is a different story. By the time your carrier adds margin, admin fees, and billing overhead, retail rates balloon fast.
EE's standard international rate to the US sits at around 55p per minute without a bolt-on. Three's "Go Roam" works in the US, but it's designed for roaming while you're there, not calling from home. O2's international calling add-on helps, but it still runs around 3p–15p per minute depending on the plan tier you're on.
None of that is necessary anymore.
What VoIP Actually Costs for UK-to-US Calls
Browser-based VoIP routes your call over the internet instead of through the traditional phone network. The rate to reach a US or Canadian number is $0.02 per minute. No connection fee, no monthly minimum, no per-call surcharge.
At that rate, a 30-minute call to New York costs $0.60. A two-hour call to Los Angeles? $2.40. Compare that to a carrier add-on where the same two hours might run you £6–£10 depending on your plan.
The underlying reason is simple: VoIP services buy termination in bulk at near-wholesale rates and pass most of that saving on. You can read a full breakdown in our guide to how international calling rates are calculated if you want the mechanics. The short version: you've been paying a middleman markup you don't need to pay.
How to Call a US Number from Your UK Browser in Two Steps
This takes about 90 seconds the first time. No download, no installation, no credit card required just to try it.
Step 1: Go to GlobCall.com/call/usa. You'll see a dialpad open in your browser — Chrome, Firefox, Safari, Edge, doesn't matter. Your microphone permission will be requested once.
Step 2: Top up a small balance and dial. Add as little as a few dollars, dial the US number with the country code (+1), and hit call. Your call goes live in seconds.
The audio runs over your existing broadband or WiFi connection. If you've got a 10Mbps+ connection — which covers the vast majority of UK households — you won't notice any difference from a landline call. On a slow connection, you might get a slight delay; switching to wired fixes that instantly.
No account is required to browse rates. No subscription is required to top up. You pay exactly what you use.
How This Compares to the Other Real Options
There are a handful of legitimate alternatives, and it's worth being straight about what each one actually costs.
WhatsApp / FaceTime / Google Meet — Free, but only works if the person in the US also has the app open and accepts the call. Try calling a US business phone number, a landline, or someone who doesn't have the app. It doesn't work. Free app-to-app calling and paid-rate calls to real phone numbers are completely different things. See our WhatsApp alternatives comparison for the full picture.
Google Voice — Available to US users, but the free tier doesn't work from UK accounts without workarounds, and the paid version isn't available internationally. Most UK users hit a wall fast.
Calling cards — Still exist, still marketed to UK-to-US callers, still carrying hidden connection fees that inflate the real cost well above the advertised rate. Our calling cards vs VoIP breakdown goes into detail, but the summary is: the headline rate is rarely the real rate.
Carrier bolt-ons — Useful if you're already paying for a bundle and make very few calls. Not cost-effective if you're calling regularly. We covered the full comparison in calling abroad from EE or Three — add-ons vs VoIP.
Microsoft Teams Phone — A serious option for businesses, but you're paying per seat, per month, plus a calling plan. For personal use or a small team, it's overkill. Here's a Teams Phone vs VoIP cost breakdown if you need it.
Does Call Quality Hold Up on a UK Broadband Connection?
Yes — with one condition. Your connection needs to be stable, not necessarily fast. VoIP audio uses about 80–100 kbps per active call. A standard BT, Sky, or Virgin Media broadband connection handles that without breaking a sweat.
The real quality killers are packet loss and jitter — network instability, not raw bandwidth. If you're on WiFi and dropping packets, you'll hear it. Switch to wired or move closer to your router, and the problem usually disappears.
Browser-based calls also benefit from modern browser audio engines, which handle echo cancellation and background noise suppression automatically. You don't need a headset, though using one does noticeably improve the experience on both ends.

What About Calling US Toll-Free Numbers from the UK?
Here's what most people miss: 1-800, 1-888, 1-877, and other US toll-free numbers are not free when called from outside the US. The toll-free designation only applies to domestic US callers. From the UK, they're billed as standard international calls.
The rate is still $0.02/min via GlobCall — the same as any other US number. But you should know upfront that the "free" label doesn't travel internationally. If you need to reach a US airline, bank, or government line from abroad, our guide to calling 1-800 numbers from outside the USA walks through your options and what to expect.
Frequently Asked Questions
Can I call any US number this way, including mobile and landlines?
Yes. VoIP services like GlobCall connect to the full US public telephone network — mobile numbers, landlines, business lines, and toll-free numbers all work. The rate is $0.02/min across the board, with no distinction between mobile and landline for US numbers specifically.
Do I need a US phone number to call the USA from the UK?
No. You can call any US number without having a US number yourself. If you want the person you're calling to see a US caller ID, or if you need a US inbound number for callbacks, GlobCall offers virtual US numbers as a separate option.
Is it legal to make VoIP calls from the UK?
Completely legal. VoIP calling is regulated and widely used across the UK by consumers and businesses alike. Services like GlobCall operate under standard telecommunications frameworks. There's nothing grey about it.
What happens if the call drops mid-conversation?
You simply redial. There's no per-call connection fee on top of the per-minute rate, so a dropped call doesn't cost you an extra charge to reconnect. Your balance is only debited for time used.
Can I use this for business calls, not just personal ones?
Yes — and it scales well. GlobCall's business plan supports unlimited team members on a shared balance with no per-seat fees, which is a different model from most business VoIP providers. Worth reading if you've got a team making regular US calls.
The Bottom Line
Calling the US from the UK for under $0.05 a minute isn't a niche workaround. It's the straightforward reality of what VoIP actually costs in 2026.
Here's what you've learned:
- $0.02/min is the real rate for UK-to-US calls via browser VoIP, no contract, no minimum spend
- Carrier add-ons and calling cards both carry markup and hidden fees that push your real cost up significantly
- App-to-app services are free but limited — they don't reach real phone numbers reliably
- Call quality is not an issue on any standard UK broadband connection
- Toll-free US numbers aren't free from the UK, but the VoIP rate still applies
Ready to try it? Head to GlobCall.com/call, top up a couple of dollars, and make your first call. Thirty minutes to the US will cost you about $0.60. That's less than a coffee, and it goes directly to the call — not to someone's margin.
