Google Assistant not sending SMS - Huawei Y7 (2019)

[Rodster]

Hi folks

My mum who is blind, relies on Google Asst and for the most part it is excellent.

She has an unlocked Huawei Y7 2019 and has just started a new contract with O2 after coming from EE.

I have updated everything i can think of from a software pov, but i have a feeling that there is an issue with her APN config, but for the life of me i cant remember how to adjust it.

Im sure its mobile.o2.co.uk as default.

anyway, she asks google to create a text and send to me, it creates, verifies recipient and sends, within a second she recieves a message stating 'sorry but the sms is not configured correctly'

If i send a text manually its no issue, but as she is blind she cannot do this manually.

When on EE, this was not an issue - hence why i think its an O2 config issue and not a google issue

Can anyone give me step by step 'idiots guide' please?

many thanks in advance
