In order to send a Glympse using Verizon Messages, first select the number of the person you would like to send your location to either through your contacts or by entering in their phone number.
Next, tap the plus symbol on the left-hand side of the 'Type a message...' box and select Glympse from the options.
The next options that appear are - Request Location, Share Location, or your favorites such as Work or Home.
Select whether you would like to send a location request to someone, or whether to share your location with someone. If you choose to share your location, you will then be presented with the option to add an address for either your current location or your destination, and for the length of time you wish to share, then tap Send Glympse.
