How to Call United Kingdom from the U.S.

Making an international call is easy.

To call the United Kingdom, you can use either your Ooma Telo-connected home phone or the Ooma Mobile app.

  • First, dial 011 to exit the U.S. telephone system.
  • Now dial the country code for the United Kingdom, which is 44.
  • Next, dial the 10-digit local number.

Keep the following considerations in mind when calling the United Kingdom. You will likely encounter listed numbers beginning with a “0” frequently. This 0 is a “trunk code” and is part of the United Kingdom’s national dialing format (just like how we in the U.S. sometimes use “1” when dialing a long distance number). Dial only the numbers after the 0 to ensure the call goes through properly.

Calls made through the Ooma Mobile app do not use any minutes or incur international charges on your wireless bill. Instead, these calls are routed over your data connection and may count against your data allotment if you’re not on an unlimited plan with your carrier. If possible, connect to a Wi-Fi hotspot to place calls in order to minimize data usage.

Calling another Ooma customer, regardless of which country they’re in, is free of charge for as long as you want to talk. If you encounter any issues or have any further questions, feel free to get in contact with us via our Customer Support website at https://support.ooma.com.

With both the Ooma World Plan and Ooma World Plus Plan, all calls to standard numbers in the United Kingdom are unlimited. Calls to special service numbers are charged at Ooma’s standard rates, which are listed in the previous section. In order to decide which plan is best for you, it’s helpful to review both international plans and see which other countries are included.

In total, the Ooma World Plan gives you unlimited calling to landline numbers in 60 countries and mobile numbers in 10 countries for $17.99 per month. The Ooma World Plus Plan adds an additional 10 countries for landlines (70 in all) and 30 more countries for mobile numbers (40 in all) for $25.99 per month.

International Calling to United Kingdom

For international calls to the United Kingdom with either Ooma’s Basic Service or Premier Service, per-minute charges vary based on the type of number called rather than whether it is a landline or mobile phone. Ooma’s base rate for regular residential and business numbers is $0.028 per minute.

Calls to any special service number starting with 70 are billed at $0.315 per minute, while calls to numbers starting with 3, 4, 5 or 6 are billed at $0.65 per minute. Calls to numbers in the 843, 844, 845, 870, 871, 872 and 873 area codes are all billed at a $0.315-per-minute rate.

What is a special service number? These numbers are used by businesses and organizations in the U.K. that are looking to recoup some of the costs associated with operating call centers by splitting the fees with the caller, or to allow for one nationwide number that anyone can call at a lower rate than traditional long distance. You can think of these numbers as somewhat of a cross between 800 and 900 numbers here in the U.S.

While Basic Service has no monthly fee for crystal-clear nationwide calling, Premier Service offers a whole host of additional features for a low monthly charge. For example, Premier Service customers get powerful call-blocking tools to protect them against telemarketers and robocalls, as well as an Instant Second LineTM for making and receiving calls when your primary line is in use, the Ooma Mobile app for making calls from your mobile phone anywhere you are, voicemail access through email and text notifications, free unlimited calling to Canada and Mexico, plus many others that Basic Service doesn’t provide.

Calling the U.K. with Ooma will also save you money. Verizon charges up to $1.69 per minute to place a U.K. phone call, depending on your plan. Calls to service numbers are also not possible in many cases with Verizon and other international calling providers, as they are blocked and may also result in hidden charges you might not otherwise expect.

Ooma-to-Ooma calls are 100% free regardless of the amount of time you talk, so if your contact in the United Kingdom is also an Ooma customer, you can talk as long as you want and it won’t cost a penny. You’ll also have calls in crystal-clear HD voice, which is much better quality than standard telephone lines can provide.
