Welcome to the Community, @Khairullah1 😊
It's awesome to hear you're looking to come on board, and it's really easy to bring your number over.
If you already have an EE SIM, you just need to request a code called a PAC from Vodafone, then set up the transfer here:
Transfer your number to EE | Mobile Help | EE
If you don't have a SIM yet, don't worry. You can still request a PAC from Vodafone, and supply this when you place the order.
Once your SIM is active on our network this will initiate the transfer to take place on the next working day if before 5:30pm or the following day if after.
All the details you need are on the help page I shared above, too!
