Common Questions About Calling United Kingdom
When should I use + instead of 00?
The + symbol works from any mobile phone anywhere in the world and replaces each country's exit code, so you never need to memorize them. 00 is the most common exit code and works on both landlines and mobiles. On a mobile, always prefer + — it is the most reliable.
Why do I drop the leading 0 of the area or mobile code when calling from abroad?
The leading 0 is a national trunk prefix used only for domestic calls. When calling internationally, the country code +44 takes its place, so you remove that 0 — otherwise the number is wrong and the call fails.
How do I call a mobile versus a landline in United Kingdom?
For a mobile: dial +44 then the mobile number without its leading 0. For a landline: dial +44, then the city code (without its leading 0), then the local number. Mobile numbers never need a city code.
