Text messages are character-based, which means the length of your message can affect how it is delivered.
Most modern mobile phones and cellular networks support standard SMS messages of up to 160 characters. Longer messages may be automatically divided into multiple segments and then reassembled by the recipient's phone. Many modern devices can successfully receive much longer messages; however, delivery and formatting can vary depending on the recipient's device and cellular provider.
Some older devices or certain types of SMS messages may have lower character limits.
For the most reliable delivery to your entire congregation, RakefetOnline recommends keeping text messages brief and ideally no longer than 160 characters.
If you know that members of your congregation may be using older mobile technology, consider keeping messages even shorter—approximately 70 characters or fewer.
Best Practice: SMS works best for short announcements, reminders, alerts, and updates. For detailed information, consider using your text message to direct members to an email, website, form, or member portal.
