Maintaining contact with friends, family, or business associates in the United States from the UK doesn’t have to drain your wallet. Traditional phone providers often charge premium rates for international calls—sometimes as high as £1 per minute—with additional surcharges that aren't always clear upfront. Fortunately, modern communication technology offers smarter, more transparent alternatives. With the right tools and a bit of planning, you can make high-quality calls to the USA at a fraction of the cost, all while avoiding sneaky fees.
Why International Calling Costs Vary So Much
The price of calling the USA from the UK depends on multiple factors: your service provider, whether the call is mobile or landline, time of day, and contract terms. Major UK telecoms like BT, EE, and O2 typically include international calling add-ons or offer pay-as-you-go rates that can range from 5p to over 30p per minute—even on \"inclusive\" plans where fine print may limit free minutes to specific countries not including the US.
Hidden charges are common. For example, some providers advertise “unlimited EU calls” but exclude non-EU destinations like the USA. Others apply connection fees or round up call durations to the nearest minute, inflating costs over time. These practices make it essential to look beyond traditional networks and explore digital-first alternatives.
“Most consumers overpay for international calling because they don’t realize how much cheaper internet-based services are.” — Sarah Lin, Telecommunications Analyst at GlobalCom Insights
Top 5 Smart & Affordable Calling Methods
The following methods combine low cost, reliability, and transparency—ensuring you know exactly what you're paying, if anything.
1. Use VoIP Services (Voice over Internet Protocol)
Voice over Internet Protocol (VoIP) converts voice into digital signals transmitted over the internet. Services like Skype, Google Voice, and Vonage allow users to make low-cost or even free calls to US numbers.
- Skype: Offers pay-as-you-go credit starting at 4.8p/minute for calls to US landlines and mobiles. No subscription needed.
- Google Voice: Free calls to US numbers if you have a US account (accessible via a temporary US number through a friend or virtual assistant).
- Vonage: Monthly plans start at £6 for unlimited US calling.
2. Leverage Messaging Apps with Free Voice Calls
Apps like WhatsApp, Facebook Messenger, Telegram, and Signal use your internet connection to place free voice and video calls. As long as both parties have the app installed and stable Wi-Fi or data, these platforms eliminate per-minute charges entirely.
WhatsApp alone has over 2 billion users worldwide, making it one of the most accessible options. It supports group calls, end-to-end encryption, and works seamlessly across devices.
3. Switch to an International-Focused Mobile Plan
Some UK mobile providers now offer inclusive international calling in their standard tariffs. Giffgaff, for instance, includes free calls to the USA in its top-tier plans. Similarly, Smarty and iD Mobile let you add bolt-ons for unlimited US calling at under £3/month.
| Provider | Monthly Cost | US Calling Benefit | Notes |
|---|---|---|---|
| Giffgaff (Goodybag XL) | £25 | Unlimited calls to US landlines & mobiles | No contract; includes 12GB data |
| Smarty | £17 + £2.50 bolt-on | Unlimited US calls | Fibre broadband customers only |
| iD Mobile (Unlimited+) | £28 | Free US calling | Includes unlimited data and roaming |
4. Use eSIMs or Travel SIM Cards
If you travel frequently between the UK and USA, consider an eSIM or dual-SIM setup. Providers like Airalo and Nomad offer affordable data-only eSIMs with local US numbers, allowing you to use WhatsApp or FaceTime freely.
Alternatively, LycaMobile and OneSimCard sell international SIM cards with low per-minute rates to the US (as low as 5p/min). Just ensure your phone is unlocked before switching SIMs.
5. Virtual Phone Numbers with Local Presence
Services like MySudo or Hushed provide disposable US phone numbers for receiving and making calls via app. You can purchase a number for around £1.50/month and top up calling credit at competitive rates. This is ideal for freelancers, remote workers, or those managing US-based clients who expect a local contact number.
Step-by-Step Guide to Setting Up Low-Cost Calling
Follow this sequence to transition smoothly from expensive traditional calls to affordable, fee-free communication:
- Assess your calling needs: Estimate how many minutes per week you spend calling the US.
- Check your current plan: Review your mobile or landline contract for international calling fees and exclusions.
- Choose a primary method: Decide between VoIP, messaging apps, or upgraded mobile plans based on usage frequency.
- Download and configure apps: Install WhatsApp, Skype, or Google Voice and verify your identity if required.
- Test call quality: Make a short test call during off-peak hours to assess audio clarity and latency.
- Inform contacts: Let family or colleagues know which platform you’ll be using regularly.
- Monitor usage and adjust: After one month, evaluate cost savings and switch strategies if needed.
Real Example: How Emma Cut Her Monthly Bill by 80%
Emma, a freelance graphic designer from Manchester, regularly collaborated with clients in New York. She was previously spending over £45 monthly on her mobile plan’s international calling add-on, plus extra charges for weekend calls outside her allowance.
After researching alternatives, she switched to a Giffgaff Goodybag XL (£25/month), which included unlimited calls to the US. She also started using WhatsApp for quick check-ins and Zoom for client meetings. Within two months, her average communication cost dropped to £25—and her call quality improved due to better bandwidth management.
She now saves nearly £20 each month, which she reinvests into her home office setup. “I didn’t realise my old provider was charging me double for the same service,” she said. “Switching took less than 20 minutes online.”
Avoiding Hidden Fees: What to Watch For
Even seemingly cheap services can hide costs. Be vigilant about the following:
- Connection fees: Some providers charge a fixed fee per call (e.g., 20p) regardless of duration.
- Rounding up: A 2-minute, 10-second call might be billed as 3 minutes.
- Roaming data charges: Using WhatsApp abroad without Wi-Fi can incur high data fees unless you have a travel package.
- Auto-renewals: Free trials for VoIP services may convert to paid subscriptions without notice.

- ☐ Compare mobile plans with US calling inclusions
- ☐ Install at least one free calling app (e.g., WhatsApp)
- ☐ Top up VoIP credit only when needed
- ☐ Use Wi-Fi whenever possible to avoid data charges
- ☐ Monitor bills for unexpected surcharges
