Not Receiving OTP codes from anyone

[SteveH65]

Just swapped my Pay Monthly sim from an android phone into a new iPhone, everything seemed to be working fine until I needed to receive a OTP code from Amazon. 
It never arrived, same problem with bank and with MyO2

I don't have any blocked numbers and have confirmed that my number is in the correct format for iMessage. Doesnt even work if I turn iMessage off.

Do I need to reset something?

Do I need to tell O2 I have moved from Android to Apple? If so how do I do this?

Thanks for any help

Do you have a zero spend cap on the account @SteveH65 ?

[SteveH65]

I've had this o2 account for many years, I'm not aware of ever having a spend cap. I've had additional charges on the account before so I assume not.
If only I could get to talk to someone at O2, no live chat available for me

Some customers have isssues with short codes. We had a similar one here

https://community.o2.co.uk/t5/Apple/Short-code-texts-not-working/m-p/1193285/highlight/true#M161974 

It was sorted in the end by O2 gurus.

I wonder if @O2Lisa or @O2Daniel  could look at this tomorrow?

Woah, what happened.
Been struggling with this all day and miraculously 10 mins after I post here all my OTP texts come flooding through.
Bit weird as they have not been working at all for a few days.
Did someone flick a switch?
Thanks for your help anyway

Edit:

Irrelevant as issue is resolved.
