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 Ken
    Do you know why t-mobile, here in London, England, have changed all the call numbers and text numbers on my Nokia phone from first digit 0 to +44 and does that mean that they’re routing my calls abroad and charging me inflated fees? Or what are they up to? Or possibly is it some kind of hacking? Or just a fault? I’d assume that it’s t-mobile or hackers trying to rip me off as otherwise what would be the motivation for a change like that. Or what? Thanks if you can help,

    • Hi Dave,
      Many thanks for your message. I can assure you this is definitely not due to hackers or anything like that! Lots of mobile phones actually store phone numbers in your address book with the +44 prefix. The reason for that is so it will continue to work when you go abroad (so even if you were using a SIM card from another country, the +44 prefix ensures it will always be treated as a UK phone number).
      Rest assured, you won’t be charged for an international call if you’re inside the UK (you’ll pay the exact same regardless of whether you dial with +44 or 0 at the start of the number).
      Hope this helps,

    Hi Ken
    A quick question; I’m trying to contact an UK car hire company from my mobile here in the UK. The only number they appear to be giving out is their International one starting 0044. Will I be charged at International rates for dialling this number? Thanks and thanks for a very informative web site.

    • Hi Derek,
      Thanks for your comment! If you’re calling the phone number from inside the UK, you’ll only be charged the normal UK rate (so absolutely fine to dial this with the 0044 prefix). If you’d like a bit of extra reassurance, you can replace the 0044 with a 0. This should give you a UK phone number in the normal format.
      Hope this helps,
