Hi
Do some of your texts or all of your texts not get received ? If some then look in your text blocking facility
https://support.apple.com/en-gb/HT201229 and ask the other people to check if their phones have the same kind of blocking facility.
Can you please check if you've not already done so what the Vodafone Network Mast Status Checker is reporting for your area.
Please use the Zoom out feature in the map to check surrounding areas for issues.
https://www.vodafone.co.uk/explore/network/uk-coverage-map/index.htmHas this happened regularly or recently ?
Are you a new customer to Vodafone via porting from another network ?
If your sending a text to another iPhone they'll be iMessages indicated by a blue bubble. These need a wifi connection or at least a stable 3G connection.
Plz try ure Sim in another phone as a process of elimination 2 rule out the phone or sim that may be at fault.
