Install the SIM Card
A SIM (Subscriber Identity Module) card stores your phone
number and information about your wireless service.
Caution! Turn the device off before installing or removing the
SIM card. Do not bend or scratch the SIM card. Take
care when handling, installing, or removing the
SIM card, and avoid exposing the SIM card to static
electricity, water, or dirt. Keep the SIM card out of
reach of small children.
1. Carefully insert the 4G LTE SIM Card into the slot,
pressing gently until it locks into place.
2. Make sure that the card’s gold contacts face down and
that the upper-left angled corner of the card is
positioned as shown.
