Mobile numbers start with the mobile operator code (which begins from 07X, followed by seven digits for the main telephone number).

A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .
The service name E2U+sip is an ENUM string indicating that the record can be used in telephone number-to-SIP-URI queries. [4] The client applies the regular expression !^.*$!sip:customer-service@example.com!, which replaces its entire URI tel:+1-800-555-1234 with sip:customer-service@example.com.
Greed, in regular expression context, describes the number of characters which will be matched (often also stated as "consumed") by a variable length portion of a regular expression – a token or group followed by a quantifier, which specifies a number (or range of numbers) of tokens. If the portion of the regular expression is "greedy", it ...
