Ideas for birthday text messages are available on sites such as WishesQuotes.com, Pinterest.com, AllBestMessages.com and WishAFriend.com. Some sites contain text that users can copy and past into a text message, while others offer pictures of eCards to send via text.
Deciding what kind of text message to send someone for her birthday depends on the sender's relationship with that person. For example, close friends and siblings often share humorous or silly birthday text messages due the intimate and relaxed nature of the relationship. Alternately, a birthday text message to a boss, grandparent or co-worker should be more formal, respectful and positive.
