Your Verizon Wireless SIM card
Use your Verizon Wireless 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 SIM (Subscriber Identity Module) card stores your phone
number and other important information. Do not bend or scratch
your SIM card. Avoid exposing it to static electricity, water or dirt.
If your 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.

Changing the network your phone connects to

By default, your phone is set to Global mode. It automatically searches for
the appropriate network in your location (CDMA or GSM) and then
connects to it.
When roaming in countries outside of North America where both CDMA
and GSM networks are used, you can choose what network to connect to.
1. On the Start screen, slide to the left.
2. Tap Settings > cellular.
3. Tap the Mode selection box, and then select LTE and CDMA or LTE,
GSM or UMTS.
