Signal issues after 9.1 update

[Anonymous]

i upgrade the os on my iPhone 5s this morning to 9.1 and since then I've had problems with the phone signal. 

The signal is either very poor, not strong enough for a phone call or displaying 'no service'. This is happening every minute or so. 

Is is this a generic problem or O2 issue?

 We don't get any information to tell us things are being sorted out we have to go online or call to go through a procedure then they say that there is a problem with a mast

O2 have never given timescales for repairs to masts there are too many variables and only checking will give you any information .
