UK mobile phone and pager numbers are always eleven digits long and begin with 074, 075, 077, 078 or 079. (070 is for personal, 'follow-me' numbers and 076 is mainly for pagers.)
Typically, they are also written as one block of 5 digits, then another block of 6 digits - although there are no rules about this and you might see them spaced differently.
This means that a typical mobile number would look like 07xxx xxxxxx in UK format, or +44 7xxx xxxxxx in international format, where x = any number.
If you just want a non-working example, such as for including in a movie, a book, a TV programme, user documentation, etc., use one of the 'dummy numbers' specifically set aside by the regulator. These are any number between 07700 900000 and 07700 900999.
So, good non-working examples would include:
07700 900129 (or +44 7700 900129)
07700 900391 (or +44 7700 900391)
07700 900470 (or +44 7700 900470)
etc.
An example of a valid mobile phone number might be +1 417 555-0123, except with an actual mobile phone number instead of the fictitious 555-0123. An example in the UK would be +44 7700 900123, which is the (fictitious) UK mobile number 07700 900123 written in international format. A valid mobile phone number is a real phone number that actually connects to a working mobile phone.
In a mobile number, "44" is the country code for the United Kingdom. It is used when dialing UK numbers from abroad, indicating that the call is being routed to the UK. For example, if you see a mobile number starting with +44, it signifies that the number is registered in the UK.
If two UK-based mobile phones are in France, and you want to call from one to the other, dial the UK mobile number, but be sure it is in full international format. For example, the (fictitious) UK mobile number 07700 900123 would be stored as +447700900123. Start with the country code +44 for the UK (including the plus sign!), and drop the leading 0 from the UK domestic number.
You should be able to, by substituting country code +44 for the leading 0 of the UK mobile number. For example, 07700 900123 becomes +447700900123.
If you are calling from a UK mobile to Australia, dial 00 (international prefix from the UK) 61 (country code for Australia) and then the Australian number, dropping the leading 0 To call from Australia to a UK mobile, dial 0011 (international prefix from Australia) 44 (country code for Australia) and then the UK mobile number, dropping the leading 0
Dial the UK mobile number exactly the same way you do when the mobile is in the UK.
Dial the UK mobile number exactly the same way you do when the mobile is at home in the UK. The mobile network will automatically locate it.
Dial 00 44 then the full UK mobile number minus its leading zero. For example, UK mobile 07123 456789 would be dialled as 00 44 7123 456789 from Italy.
This is a UK mobile (cell phone) number.
If you are in the UK, dial the mobile number. If you are outside the UK, dial the international access prefix, then the country code for the UK (+44), and then the mobile number without the leading 0.
Doesn't matter where you are in the world.... Take for example the mobile number 07979 111111. Wherever you are in the world, you would dial 0044 (the code fo the UK - then 7979 111111 (you omit the first zero from the number)
there is no dialling code , just dial the number as if the person u r calling in the UK as long as he has a UK mobile number
