Alternatively, if your contacts abroad are calling you from a GSM mobile phone, they can input the +44 prefix directly into their handset (to get the plus sign, you’ll need to long-press on the zero button in your mobile phone’s dialler).

If you’re using a UK-based SIM card in the UK or Europe, it will always be free for you to receive an incoming phone call (to be clear, there are no additional charges for receiving an incoming international phone call).

If you’re travelling outside of Europe, the normal roaming charges might apply for receiving an incoming phone call.

Frequently Asked Questions

Travelling Abroad

If you’re travelling abroad to another country and roaming on your UK-based SIM card, your international phone number will still remain the same. The +44 at the beginning of your international phone number refers to the fact you have a UK-based number (you don’t necessarily need to be physically inside the UK).

If you’re using a different SIM card when travelling abroad, you may have a local phone number in the country where you purchased your SIM card. In this case, you’ll also have a new international phone number.

For more information and for useful tips about using your mobile phone abroad, please see our in-depth guide to this topic.

Leading Zero

When you convert a UK phone number into an international phone number, you should remove the zero at the start and replace it with +44. A common mistake is to leave the zero in place – this is incorrect and will lead to the phone call failing to connect.

UK phone numbers are sometimes written with the leading zero in brackets: for instance, +44 (0) 7123 456 789. If you see a phone number written in this format, you should remove the zero that’s in brackets to get your international phone number.

Call Costs

Your contacts who are calling you from abroad will need to pay their phone company for an international phone call to the UK.

Typically, a different rate is charged for calls going to a UK landline and to a UK mobile. UK landline phone numbers begin with either +44 1 or +44 2, whereas UK mobile phone numbers begin with +44 7. The interactive tool above will tell you about the type of phone number being called.

If you’d like to call internationally from the UK, see our guide to the best mobile phone networks for international calling.

Visiting The UK

If you’re visiting the UK on a short-term trip, it may possibly make sense to get a UK-based SIM card. If you do this, you’ll be assigned a new UK-based phone number. Any contacts living outside the UK will need to call you on your international phone number (use the form above to find out your international number).

  • Hi I am going to Portugal and will be using my UK mobile and sim. I want to know if I ring someone in the UK how will the caller ID be displayed? My normal number starting with a 0 or something else?

    • Hi Terry,
      Your normal UK phone number will show up on other people’s screen, and if you’re in their address book, it’ll be recognised as you too.
      Hope this helps,
      Ken

  • I will be travelling to Italy and purchased a sim card which allows to be used across Europe. The sim card is in UK number. If my family member (not from Europe or US) would like to call me, do they add UK country code +44 or +39 which is Italy’s country code. My mobile starts with 077.
    While at it, I tried using the table you have provided and entered my contact number. It shows +44 is required to be added. So I would like to confirm.

    • Hi Mau,
      Thanks for your comment. As you have a UK-based SIM card, they will need to dial the UK country prefix of +44. The country code always refers to where your SIM card is based, rather than which country you’re physically located in at that time.
      Hope this helps!
      Ken

  • Hi I will be in the USA for 2 weeks on holiday from the UK, my family who live in USA want to ring my mobile to keep in contact, what number should they dial from their US mobile?

    • Hi Karen,
      Are you using your normal UK phone number? If so, it’ll be your normal UK phone number with the 0 at the start replaced by +44 (or 011 44 if they’re calling from a landline).
      Hope this helps,
      Ken
