Buying a phone online

recently I want to upgrade my phone. However, there is a question about the SIM card after buying. It says that the new SIM card will be sent with the new device. But I already have my current SIM card in my phone, so which one should I use?

Hello Xinyuan,


  Welcome to the community!


  Congratulations on getting a new phone! You do not necessarily need to use the new SIM card. It is provided in case your new phone requires a different sized SIM from your current phone. If both of your phones use the same sized SIM, you can continue to use your old SIM. If your new phone requires a different sized SIM, you can update your SIM via My Account. You should note that only one SIM can be active on your account at a time. If you update your SIM, your old SIM will no longer be active.


Hope this helps 😀
