Mobile phone numbers
07428 numbers are for mobile phones in the United Kingdom. They were first allocated for use in June 2010.
All UK 07 numbers are for mobiles, pagers and personal numbering.
Which network is 07428?
07428 numbers are allocated to Three.
It is no longer possible to tell the operator of a UK mobile phone from its number alone, as customers are free to take their number with them when they change networks. The 07428 prefix is not a reliable indicator of which network a phone is currently connected to, only which network issued it originally.
These are normal mobile numbers and will usually be charged at standard rates.
Formatting an 07428 number
