There are a lot of people who would like to use the same sim card while they are switching phones. For example, you would like to upgrade to a newer phone, but you would like to keep your number the same.
These are some things that you can do:
• Make sure that your sim card, something that will have your number on it, will be the same cut as your new phone.
• If it is the same, you just need to transfer the sim card to the new phone. If not, you can cut the sim card before transferring it to your new phone.
• Your phone will have mechanisms that will allow you to transfer the sim card easily.
• Transfer your sim card to your new phone.
Now that you have done everything, you will be able to use the same sim card.
