Your Verizon Wireless nano SIM card
Use your Verizon Wireless nano SIM card to make and receive calls, text,
and email messages and surf the Web while traveling outside of the U.S. in
supported destinations.
Your nano SIM (Subscriber Identity Module) card stores your
phone number and other important information. Do not bend or
scratch your nano SIM card. Avoid exposing it to static electricity,
water or dirt. If your nano SIM card is lost or damaged while in the
U.S., please dial *611 from your Verizon Wireless device or
1-800-922-0204 from any phone to speak with a Customer
Service Representative. From outside of the U.S., please refer to
the Verizon Wireless Global Support Guide, welcome letter and
calling card that came with your device. This will enable you to
make calls toll free from landlines in most countries where we offer
Global Phone service.
