The cheapest way to make international calls from the UK depends on your destination, call duration, and whether the recipient uses the internet or a regular telephone. WhatsApp and FaceTime offer free app-to-app calls over Wi-Fi, while mobile networks such as Lebara and Lycamobile provide plans with international minutes. For people who regularly dial overseas landlines or mobiles, services such as O2 International Bolt On and EE international add-ons can reduce costs. Comparing destination-specific rates, monthly fees, and included allowances helps you avoid unexpected charges.

Free or Cheap International Calls to Mobile Phones
If the person you are contacting uses the same communication application, an internet call is usually the cheapest option. These services do not charge a separate international voice tariff for app-to-app calls, although mobile data, roaming, and internet access may still cost money.
| Service | Cost for app-to-app calls | Can call ordinary mobile numbers? | Best use |
|---|---|---|---|
| No separate call charge over the internet | No, not through its standard voice-calling feature | Everyday personal calls | |
| FaceTime | No separate international call tariff over the internet | No, not as a standard international telephone call | Calls between Apple users |
| Microsoft Teams Free | Free app-to-app calls within supported features | No consumer paid telephone dialling plan | Personal and group internet calls |
1. WhatsApp
WhatsApp voice calls use an internet connection rather than a conventional international telephone tariff. There is no separate per-minute international voice charge for calls between WhatsApp users, but mobile data charges may apply. Wi-Fi is generally the most economical choice when available.
Key features
-
Voice and video calls between compatible accounts.
-
Group calling and messaging.

Internet-based communication on supported devices.

End-to-end encryption for personal calls.
Pros and cons
| Pros | Cons |
|---|---|

Skype was retired on 5 May 2025, and its remaining paid calling arrangements are being phased out; Skype subscriptions ended in May 2026. Therefore, Teams Free should be presented as an app-to-app calling option rather than a general replacement for paid international dialling.
Key features
-
Voice and video communication between supported users.
-
Group meetings and messaging.
-
Availability across supported devices.
Pros and cons
| Pros | Cons |
|---|---|
| Useful for remote conversations | Both parties need access to compatible features |

Networks with international minutes included as standard
Lebara and Lycamobile are useful starting points for people who frequently call overseas. Spusu may suit callers who mainly contact European destinations, while other networks can become competitive when a suitable add-on is available.
| Network | International calling offer | Best suited to | What to check |
|---|---|---|---|
| Lebara | SIM-only plans include international minutes for more than 50 countries; allowances vary by plan | Regular calls to supported destinations | Country list, included minutes, and excess rates |
| Lycamobile | International bundles and selected plans with overseas minutes | Frequent calls to supported countries | Current bundle, destination, and renewal conditions |
| Spusu | Plan-specific allowances and international calling options | Callers who need to check European coverage | Current UK tariff and eligible destinations |
Lebara confirms that its SIM-only plans include calls to more than 50 countries, with standard landline and mobile calls drawing from the international allowance. Its published offers vary by plan, so the included minutes should be checked before purchase.
1. Lebara
Lebara is a strong option for callers who need international minutes bundled with their UK mobile service. Its plan range includes different allowances, so a cheaper package may be sufficient for occasional conversations, while heavier users may need more minutes. Calls outside the included allowance can incur standard rates.
2. Lycamobile
Lycamobile focuses on international communication and offers bundles covering selected overseas destinations. It can be worth comparing against Lebara when most calls go to the same country. Check whether the specific destination, landline or mobile type, and intended call volume are covered by the chosen plan.
3. Spusu
Spusu is worth considering for people who make frequent calls to European destinations. However, do not assume that an allowance advertised for a particular plan applies to every European country or to every type of number. Confirm the current UK plan terms before switching.
Networks with international add-ons
| Network | Current published option or policy | Best suited to |
|---|---|---|
| O2 | The International Bolt On costs £3 per month for Pay Monthly customers, with discounted calls to international mobiles and landlines in more than 200 countries, starting at 1p per minute. | Frequent calls to supported countries, especially when destination rates are low. |
| EE | EE offers international calling add-ons for selected destinations. Remove the unverified claim that International Extra provides 250 minutes to 100 countries for £30 per month; a reliable current price and allowance for that specific offer could not be confirmed. | Customers whose destinations are covered by an eligible international add-on. |
| Vodafone | International Saver 100 costs £6.95 per month for 100 minutes to 100 destinations. International Saver 500 costs £14 per month for 500 minutes to 100 destinations. Call Abroad Extras also include 75 minutes for £14 or 200 minutes for £28.10 to 200 destinations. | Regular international callers who can use the included minutes. |
| Sky Mobile | International calls are subject to destination-specific charges under the applicable tariff. A current International Saver bundle with the previously stated coverage of more than 60 destinations could not be verified, so that claim should be removed. | Customers who make occasional international calls and compare per-minute costs. |
| VOXI | The 100 International Minutes Extra costs £6.50 for 100 minutes to 101 destinations. It lasts 30 days and renews automatically when payment details are registered, unless cancelled. | Customers who regularly call eligible international destinations and need a fixed allowance. |
O2 confirms that its International Bolt On costs £3 monthly and offers discounted calls to landlines and mobiles in more than 200 countries, with rates starting at 1p per minute. EE publishes several destination-specific add-ons, including a 250-minute option for 100 countries at £30 per month. These are different pricing models, so compare the actual destination and likely usage.
Which network is best for your destination?
The cheapest UK network for international calls depends on the destination, whether you are calling a mobile or landline, and the international minutes included in your plan. Lebara advertises international minutes to more than 50 countries, while O2 and EE offer separate international calling options. Compare the actual destination rates and included allowances before ranking a provider as the cheapest.
| Destination | Networks to compare | What to check |
|---|---|---|
| India | Lebara, Lycamobile, O2, EE | Included minutes and mobile-number rates |
| Pakistan | Lebara, Lycamobile, O2, EE | Eligible international bundle and excess charges |
| Nigeria and Ghana | Lebara, Lycamobile, O2, EE | Country inclusion and remaining allowance |
| Bangladesh | Lebara, Lycamobile, O2 | Bundle eligibility and direct-dialling rates |
| France, Germany, Spain, Poland | Spusu, Lebara, Lycamobile, EE | European destination coverage and minute limits |
| USA and Canada | Lebara, Lycamobile, O2, EE | North American calling bundle versus standard rates |
| Australia and New Zealand | Lebara, Lycamobile, O2, EE | Landline and mobile prices may differ |
O2’s International Bolt On lists these destinations among its international calling coverage, while EE provides separate European, USA and Canada, and rest-of-world bundles. Lebara also publishes international allowances across more than 50 countries. Exact rates can change, so verify the current tariff for the number you intend to dial.
Reduce International Calling Costs With VoIP
Voice over Internet Protocol (VoIP) carries calls over an internet connection instead of relying entirely on traditional telephone networks. It can reduce costs for international calls, particularly when you need to reach ordinary phone numbers rather than only application users. The best choice depends on how frequently you call, the destination, and whether you need a personal or business service.
-
Compare the full cost: Include monthly subscriptions, per-minute charges, connection fees, taxes, and currency conversion.
-
Use Wi-Fi where possible: Internet calls can reduce mobile data costs, particularly for lengthy conversations.
-
Check landline and mobile rates separately: Providers may charge different amounts for each type.
-
Choose a bundle for regular calling: Calculate the cost per included minute and check whether unused allowances expire.
-
Test the connection: Try a short call before relying on a new service for an important conversation.
-
Protect your information: Use reputable providers, review privacy policies, and avoid entering sensitive details into unfamiliar websites.
For example, O2’s £3 monthly International Bolt On can be attractive for frequent callers when discounted rates apply to their destination. EE’s published £30 monthly International Extra option includes 250 minutes across 100 countries, equivalent to 12p per included minute if all 250 minutes are used. That calculation excludes any additional charges and assumes the calls qualify for the allowance.
Before choosing a provider, estimate your typical monthly usage. Someone making a few short calls may pay less through a limited free service, while a person making regular calls to conventional telephone numbers may benefit from a mobile bundle or dedicated VoIP account.
Final Thoughts
The cheapest way to make international calls from the UK depends on your calling habits. WhatsApp and FaceTime are practical for free internet-based conversations, while Lebara, Lycamobile, O2, and EE offer options for reaching conventional overseas numbers. Compare current destination-specific tariffs, monthly fees, and included minutes before committing to a plan.
FAQs
-
What is the cheapest way to make international calls from the UK in 2026?
Internet-based calls through WhatsApp or FaceTime are usually the cheapest option when both people can use the same application. For ordinary telephone numbers, compare international SIM bundles, discounted add-ons, and VoIP rates for the destination.
-
Can I call an international landline for free from the UK?
Some browser-based services advertise limited free calls to supported landlines. PopTox and Ievaphone are examples, but availability and duration restrictions apply. For regular or important calls, a paid service may provide more predictable access.
-
Which UK network is best for international calls?
Lebara and Lycamobile are useful starting points because their plans include international calling options. O2 and EE may suit people who prefer a dedicated add-on. The best choice depends on the destination, included allowance, and actual call rates.
-
Is WhatsApp cheaper than a normal international phone call?
WhatsApp does not charge a separate international voice tariff for calls between users. However, internet access is required, and mobile data charges may apply. Calling someone who does not use WhatsApp requires a different method.
-
Can I call a US mobile number from the UK without paying?
You can usually avoid conventional international call charges by using an internet calling application if the recipient also uses it. Direct calls to US mobile numbers through a regular phone service generally require an applicable allowance or paid tariff.
-
Are international calling cards still worth using?
They can be useful when their rates are competitive and the service supports your destination. Check connection fees, rounding rules, expiry dates, and access-number charges before purchasing credit. Compare the total cost against a mobile bundle or VoIP provider.
-
Do international minutes included in a UK SIM plan cover every country?
No. Providers specify eligible countries, number types, and allowance limits. A plan may cover a landline but apply a different charge to a mobile or exclude particular territories. Always read the current terms.
-
Is calling abroad from the UK the same as roaming?
No. An international call is made from the UK to a foreign telephone number. Roaming happens when you use your mobile service while abroad. The applicable charges and allowances can differ substantially.
-
How can I check the cost before making an international call?
Visit your network’s official international rates page and select the destination. Confirm whether the number is a landline or mobile, whether an add-on is active, and whether connection fees or minimum billing periods apply. Check the final rate before dialling.
