Mobile phone numbers
07781 numbers are for mobile phones in Guernsey. They were first allocated for use in August 1997.
All UK 07 numbers are for mobiles, pagers and personal numbering.
Which network is 07781?
07781 numbers are allocated to Sure.
It is no longer possible to tell the operator of a mobile phone from its number alone, as customers are free to take their number with them when they change networks. The 07781 prefix is not a reliable indicator of which network a phone is currently connected to, only which network issued it originally.
07781 numbers used in Guernsey may be charged at international rates when calling from the UK.
Certain mobile phone operators exclude calls to some or all 07781 numbers from inclusive call allowances – check with your phone company before calling.
Formatting an 07781 number
There is no set format for UK mobile phone numbers, but the commonest format is: 07781 xxxxxx
For international callers, use: +44 7781 xxxxxx
Mobile numbers from the old Guernsey Telecom 04481 code were transferred to 07781 between 1999 and 2001.
The old code and the new 07781 prefix ran in parallel from 30th September 1999 until 28th April 2001, when the old 04481 code was withdrawn.
