If the screen of your mobile is displaying either of the messages "Insert SIM", "SIM error" or "SIM card rejected", try the following:
Check the SIM card is inserted properly and the right way round
Try another SIM card to see if the problem lies with your SIM card
Try your SIM in another mobile to see if the problem lies with your mobile
If an incorrect PIN has been entered on your mobile handset three times, you're given 10 attempts to enter a correct PUK (Personal Unblocking Key). If an incorrect PUK code is entered after the 10th attempt, your SIM will become permanently blocked and you'll require a new SIM card.
You can request a replacement SIM card by logging in to my Vodafone and selecting Replacement SIM - we will then post one out to you, alternatively you can visit any Vodafone store and ask for a blank replacement SIM
