SIM Card Overview
Important! Before removing or replacing the SIM card, make
sure the device is switched off. To turn the device
off, hold down the
key until the Device
options screen displays, then tap Power off.
The SIM card is loaded with your subscription details such as
your telephone number, PIN, available optional services, and
many other features.
Important! The SIM card and its information can be easily
damaged by scratching or bending, so be careful
when handling, inserting, or removing the card.
Keep all SIM cards out of reach of small children.
Some features on your device (such as Wi-Fi Calling) can be
unlocked by using a new ISIM (IP Multimedia Services
Identity Module) card. To use this new ISIM card, call or
contact T-Mobile customer service for more information.
This card contains the necessary information for identifying
and authenticating the user to the IMS (IP Multimedia
Subsystem).
If available, you can remove the previous SIM and replace it
with the new ISIM card.
Installing and Removing the SIM card

1. Carefully slide the SIM card into the SIM card socket
until the card clicks into place.
2. Make sure that the card’s gold contacts face into the
