You have had Vodafone send you a new SIM card. This has a new PIN, but you want to continue to use your old PIN with the new SIM card. How to change the PIN.
Change Vodafone PIN for SIM card – this is how it works
You remain loyal to your mobile network provider Vodafone and keep your previous cell phone number, but you still need a new SIM card. For example, you bought a new smartphone that requires a nano SIM and therefore requires a different SIM card size than your previous smartphone. So Vodafone will send you a new SIM card, usually a template from which you can break out the required SIM in three different sizes. In this case, one SIM card covers all three currently common SIM card formats.
But the new SIM card comes with a new PIN. However, you should not remember the new PIN, but continue to use the PIN of your old SIM card. No problem!
How to change the Vodafone PIN device and OS independent
Enter exactly the following character string on the virtual telephone keypad of your smartphone:
** 04 * ALTEPIN * NEUEPIN * NEUEPIN #
Then press the Call button. The default PIN of the new card should now have been replaced by your old PIN.
ALTEPIN means the PIN that Vodafone sent with the new SIM card. NEUEPIN means the PIN that you want to use with the new SIM card in the future. In our example the PIN of your old, replaced SIM card.

You can save yourself having to send a new SIM card if you dare to tailor your previous SIM to the new format you need. You can do this with a punching template. Provided that your old mini-SIM is not too old (then the chip will be a bit larger and can no longer be cut, or only at great risk). Nice side effect: You save the fee that Vodafone collects from you for sending a new SIM card.
Many modern smartphone operating systems such as iOS have a menu item in the settings for changing the PIN (for example on the iPhone under “Settings, Phone, SIM PIN, Change PIN). You can of course also take this route, but our tip works regardless of the smartphone operating system and the specific smartphone model and saves you having to search in the submenus.
SIM cards: There are these sizes
SIM cards come in different sizes. The age-old standard SIM, the size of a check card, has not been used in cell phones for a long time. The significantly smaller mini-SIM, on the other hand, is still used in normal cell phones such as the Nokia 225. The formats Micro-SIM and Nano-SIM are standard for smartphones and tablets today.
