Calling the UK from the US is often expensive with traditional carriers or outdated phone cards. In 2025, browser-based services like ZenCall make it simple to connect with any UK number for just $0.02 per minute, no apps or SIMs required.

If you have friends, family, or business contacts in the UK, you know that international calling costs can add up quickly. The good news? You don’t have to settle for expensive rates from traditional carriers or be tied to prepaid phone cards.

In this guide, we’ll explore the cheapest and most reliable ways to call the UK from the US — with a special focus on browser-based calling services that offer crystal-clear audio starting at just $0.02 per minute.

Why Calling the UK from the US Can Be Expensive

Traditional phone companies often charge high international rates to cover:

  • Network interconnection fees
  • Carrier overhead and infrastructure
  • Profit margins on top of actual costs

If you’re calling the UK regularly, these charges can stack up fast, especially for long conversations or business meetings.

Common Ways People Call the UK

1. Mobile Carrier International Plans

Most US carriers (Verizon, AT&T, T-Mobile) offer international calling add-ons. While convenient, these plans often still charge between $0.10–$1.00 per minute, depending on the destination and your base plan.

2. Phone Cards

International calling cards can be cheap upfront, but they come with hidden fees like connection charges, rounding up per-minute billing, and expiration dates.

3. App-to-App Calling

Apps like WhatsApp or FaceTime are free between users, but only if both parties have the app and a reliable internet connection. You can’t use them to call regular UK landlines or mobiles without extra steps.

The Better Way: Browser-Based Calling

Browser-based calling lets you make calls directly from your laptop or desktop to any UK number — landline or mobile — without installing an app. All you need is an internet connection, a microphone, and a headset.
