Hi yesterday I had BT infinity installed really pleased as my tesconet broadband was painfully slow.Unfortunately since the installation my cordless phone no longer shows incoming telephone numbers ,display says unknown ,even our own alternative numbers that are in the phones directory.I have called 150 and spoke to a very polite gentleman but I don't think he really understood the problem even tho I did repeat the situation .He has just offered to send me a caller display unit.thanks in advance if anyone can help
There are a number of threads relating to caller display here
Did you originally get your phone service from Tesco?

You will need to be connected to your home BT Broadband connection to view it, or any links to it that I post on this forum.
Caller display doesn't come as standard with a BT telephone line. It's considered an optional extra.
You could pay a small monthly fee to get it, or sign up to the "privacy at home" package which is free provided you make a minimum number of calls.
