Checking your data roaming settings can be helpful, especially if you're traveling internationally and have no network connection or can't send / receive email, text, pics or videos.
Enabling data roaming may incur roaming charges.
From the Home screen, navigate: Settings (lower-left) > Network & Internet.
If the Windows Settings options are not visible, tap or click the Settings Home icon (upper-left) to go to the Settings home page.
Utilize the touchscreen (if available) or mouse to select the on-screen options.
From the left-pane, select Cellular.
From the Cellular section (located on the right), select Verizon Wireless (LTE).
Ensure that 'Connect automatically' is selected (checked) then select Allow roaming.
Selected when a check mark is present.
