1) Find and buy a phone from Vodafone
So you’re out of contract and ready to switch. That’s great. Your next step is to choose a deal from Vodafone and sign up for it.
Once you’ve passed Vodafone’s credit checks, you’ll receive your phone or SIM in the post.
2) Contact Vodafone and give them your PAC code
Okay, we’re well on our way now. Next, you’ll have to ring Vodafone and tell them your PAC Code.
To get in touch, call Vodafone’s customer support team on 03333 040 191 (standard network rates apply).
3) Insert your new Vodafone SIM card
If you got a new phone, it's time to take your pin-key and unlock the handset's SIM tray. Then insert your Vodafone SIM.
If you opted for a SIM-only deal, you can just put the Vodafone SIM card in your existing phone.
The number transfer won’t take place instantly, but while it’s underway you’ll be given a temporary number to use.
4) Wait for your number to be transferred to Vodafone
Experience tells us that your number transfer should be complete the next working day.
But this depends on the network you’re joining and there are some circumstances under which it may take a bit longer. For instance, if you make your call on a working day or a weekend.
