The physical location of a mobile phone is not relevant to how you dial it. To call a US-based mobile phone from the UK, dial 00 1 and the area code and number.
This is not a UK area code and in any case, there is a digit missing from the number. If you have been phoning the UK from another country, the 44 part of the number that you have quoted is the international dialling code to phone the UK from another country. The 7 denotes that the number is a mobile (cell) number.
The first two numbers are the international dialling code to get into the UK. The 7 signifies that the number is a mobile number; no area.
+33
+44 is the international dialling code for the UK. (0)7526 is not a geographical area code, it is a mobile (cell) number.
44 is the country code for the United Kingdom, so I guess the full number is: +44 7974 xxxxxx in international format or 07974 xxxxxx when dialling within the UK. If so, 07974 (the zero is dropped when dialling from overseas) is a prefix used for mobile phones. As mobile phones in the UK are not linked to specific geographic areas, it could be a mobile owned by somebody anywhere in England, Wales, Scotland or Northern Ireland.
None. The '44' is the international dialling code for the UK, which includes England, and the '7' denotes a mobile (cell) phone number, so it could be anywhere. Are you sure that this isn't a scam?
the code is 00353 +the mobile number leaving out the first zero
try dialling 00353 before the number
Nowhere. 44 is the international dialling code for the United Kingdom (which includes England, Scotland, Wales and Northern Ireland. The 7 indicates that it is a mobile (cell) phone number. Be careful, it could be a scam.
To call an English mobile that is roaming in another country, dial the English mobile number exactly the same way you would if the mobile were in England. English mobile numbers begin with +44 74 through +44 79. On a GSM mobile, enter the number in international format, beginning with the plus sign. Otherwise, replace the plus sign with your international access prefix (most commonly 00, but many countries use other prefixes. Australia uses 0011 and other prefixes.).
