02 useful numbers


I have just joined o2 (hooray) after leaving the dark side (Vodafone).


My text messages are working fine, but I was just wondering if there is an equivalent to the Vodafone 9770. This enabled text messaging to be tested. If you sent a (free) text to 9770, Vodafone would then

text back if it was working.


Is there a list anywhere of useful o2 numbers and their function?


Thanks in advance...

With O2, you need to start your text with *0# and you will get a delivery report.

There aren't any other real sectret codes other than for checking your balance http://service.o2.co.uk/IQ/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=Companion,question=ref(User):str(Mobile),C...

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

Text MY NUMBER to 2020 and you should get a text back confirming your number.
