I have just rung the 4444 number to check my balance and I got a message
that said "the number you have dialled is no longer in service" The same
with 4445. Is it just me or have O2 changed the way that people top up ?
Problem Solved. I was using a dual SIM phone with an EE SIM as the
backup. Somehow it intercepted my 4444 call to O2 . I have disabled the
EE SIM and now it works perfectly when I dial 4444. Thanks for looking !
Yes I am still PAYG. Never had a problem with 4444 before. I have
another spare phone on PAYG that I keep in my car - I will try that out
tomorrow and see if the same message is given.
