Hi
I'm sorry to hear of your issues with your new contract and appreciate the frustration you must feel.
Your contract SIM card may need activating.
If you navigate to the Vodaphone Home page or Google -> SIM card activation Vodaphone ,the link will show.
Before that please try the following.
Turn your phone off and on or turn airplane mode on and off. This will help re connection to the Vodaphone network.
And or Go into -> Settings -General - Reset - Reset Network Settings.
If these fail then use the 'Contact Us ' link at the foot of the forum page to ask Live Chat or Customer Services by phone call to reset your account and to check your account status and mobile number allocation.
Best of luck.
😎
