My partner's mobile will cannot get text from my mobile

[Android Central Question]

My mobile is a Huawei mobile, it's always worked in the past but now she cant receive any text at all from me. However my Huawei will send text to everyone else. Im on 3 mobile, and I use three in touch via wifi text which works well
