All UK 07 numbers are for mobiles, pagers and personal numbering.
Which network uses 07700 numbers?
07700 numbers are officially shared by three different operators:
- 07700 000000 to 099999 for Cloud9 Communications

- 07700 300000 to 399999 for Sure (Jersey)
- 07700 600000 to 899999 for Sure (Jersey)
All the above 07700 numbers will have originally been issued to customers by one of these companies. However, customers are free to take their number with them when they change networks which means that an 07700 number is not a reliable indicator of which network a phone is currently connected to.
Numbers starting 07700 9 are not used. They are reserved for use as fictional numbers in television dramas, plays, books and similar.
Calls from the UK to mobile phones in Jersey are usually charged at special Channel Islands rates and will not normally be covered by inclusive minutes or bundled talktime.
Some phone companies also exclude calls to other 07700 numbers from inclusive call allowances – check your tariff details before calling.
