One number formatted incorrectly

[Danni1608]

Hi. A few months ago my partner suddenly became unable to send a text to my phone, it says message failed to send, number formatted incorrectly. However the number hasn’t changed in the last 10 years & he is able to call me & send messages on WhatsApp, so can’t see why texts won’t send to my number suddenly, but they send as normal to all other contacts. I’ve tried speaking to O2 more than once & re-set all settings, deleted & re-entered my number, re-started the phone, checked all updates & message settings. They have no more suggestions & told me to post on here, so I’m hoping someone can help because the only posts I can find similar to this issue seem to affect all numbers & not just 1 number in the contacts list.

Hey everyone, thank you so much for all your help & suggestions. I finally got my hands on his phone this evening when he got back from work & have tried clearing & re-setting everything & anything I could find after trying your suggestions. The last thing I tried was settings > apps > messages > storage > clear data & hey presto texts now send from his phone to mine!! Really wish I’d known this 3 months ago!! Thank you all for helping, at least I know something else to try if it ever does that again for any other numbers. Very random!!
