However, most users never need to change it manually.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Is_the_SM-DP_address_unique_for_each_user\"><\/span><span style=\"font-weight: 400;\">Is the SM-DP+ address unique for each user?<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">SM-DP+ is not always unique for every user. Some carriers use a shared SM-DP+ address for all customers, with the activation code identifying your specific profile.
