How do I use a prefix code to get cheap calls?
Sign up free on your chosen company's website and you can start using the prefix straightaway. Some prefix providers (also known as call override services) have contact phone numbers, but many don't - in order to keep costs down. You will be billed separately by the call override service for any calls you make.

Can I keep my home phone number if I switch?
Almost certainly – even if you're switching to or from cable. Just tell your new provider that you want to keep your number.
If I switch, will I lose services such as 1571?
Most companies offer services such as 1571. Some use BT's services and are billed by BT for them. Other providers offer their own alternatives.
A sales rep called me about moving to a new company. I didn't agree to this, but I then received a letter with a switching date. What should I do?
You have to pay bills only if there is a legal contract between you and the phone company, but be careful what you say to salespeople – contracts can be oral. If you think that you've been mis-sold a contract, you have 10 working days to tell the company to transfer you back to your original provider. If the problem is not resolved within eight weeks, you can contact the Otelo or Cisas dispute resolution schemes (every provider must belong to one of these).
