Do you have two text phone 
bases connected to the same 
phone line?
If you have you are likely to 
experience problems receiving 
text messages. Normally, only 
one SMS/text enabled base unit 
can be plugged into any line. 
If you want to keep more than 
one connected, see page 79.
Service centre numbers
To send and receive text messages you need the 
telephone number of your network’s text centre.  
If you accidentally delete the send or receive service 
centre numbers you will need to re-enter them in 
order for your text service to work. The send and 
receive centre numbers are pre-populated for BT’s 
PSTN text message service but you can change 
them to another service if you want to.
BT’s text message send service number is: 
1470P17094009 and the receive service number 
is: 0800587529.
