Welcome to Vodafone Community
My son recently updated his phone but selected vodafone prepaid not vodafone uk in error. The phone is a contract phone. How does he change it back to Vodafone uk?
This will be easy. Your Son will need to go into his network settings and change the APN from prepaid to contract.
If he text WEB to 40127 he will be able to download the correct APN settings and update the SIM on the network.
