regular expression for Indian mobile numbers

^[789]\d{9}$ should do the trick.

^     #Match the beginning of the string
[789] #Match a 7, 8 or 9
\d    #Match a digit (0-9 and anything else that is a "digit" in the regex engine)
{9}   #Repeat the previous "\d" 9 times (9 digits)
$     #Match the end of the string

UPDATE

Some Telecom operators in india introduced new mobile number series which starts with digit 6.

for that use:

^[6-9]\d{9}$

^(?:(?:\+|0{0,2})91(\s*[\-]\s*)?|[0]?)?[789]\d{9}$
