We are very sorry about the delayed response.
Could you provide us your mobile number? Which number are you trying to text to?
Morning and welcome @babymalea to the Vodafone Community.
I would recommend checking the settings for Messaging Permissions on your mobile. Just follow the next steps:
1. Go to Settings
2. Go to Apps, or Application Manager
3. Swipe to the right, until you see on top of the page showing "All"
4. Scroll down untill you find Messaging
5. Inside Messaging, look for an option called Permissions, or Send Premium SMS. Make sure this option is set to "Always Allow" in order to let your TXTs to short numbers go through.
If still no joy, just send us a private message with your mobile number and we will look into it for you.
