School Messenger Text Frequently Asked Questions

  • I received a text message that says it’s from SchoolMessenger? What does it mean?

    The text message you received is Lindbergh’s opt-in invitation message, sent by SchoolMessenger. Lindbergh’s opt in invitation message comes from 68453 and says:

    Lindbergh Schools text messages. Reply YES for aprox 3 msgs/mo. Txt HELP 4info. Msg & data rates may apply. See To continue receiving informational text messages from the school district reply with YES.

    If you don’t reply to this invitation message, you will not receive any future Lindbergh Schools texts from SchoolMessenger.

    How do I opt in to receive text messages if I did not receive the invitation text?

    Text the word YES to 68453 from your wireless device(s). Device numbers must be listed in SIS under “Household Parent 1” and “Household Parent 2”. Mobile numbers listed under the “Home Telephone 1” field will also be included. Please allow 24 hours for data synchronization to take place.

    Note: SchoolMessenger recognizes both Y and YES as acceptable responses to the opt in request.

    How do I know if my opt in reply worked?

    After you text one of the key words to 68453, the system will ALWAYS respond back with one of three messages:

    • Opt-in Response: You’re now registered with the SchoolMessenger notification service. Reply STOP to cancel, HELP for help. Msg & data rates may apply. 3msgs/mo. schoolmessenger.cong/tm
    • Opt-out Response: You’re unsubscribed from SchoolMessenger. No more messages will be sent. Reply YES to resubscribe or Help for help. Msg & data rates may apply
    • Help or Unknown Key Word Response: Reply YES to subscribe for aprox 3msgs/mo. Text STOP to quit. For more information reply HELP.

    Any other response – or no response – indicates the recipient should contact his or her wireless device provider to have SMS messaging/premium content enabled (see below for more details).

    How do recipients opt out of receiving text messages?

    To stop receiving text messages on a particular number, text STOP to 68453 at any time, or opt out online at

    I opted in, but I’m not receiving texts?

    Ensure that the district has your correct mobile number in the SIS Parent Portal. It will take up to 24 hours for this number to be active after being changed or added to the district’s system. Next, send a text with the word YES from that mobile device to 68453. You should receive an opt-in confirmation message.

    Will this replace Remind 101?

    SchoolMessenger’s text service will replace Remind 101 for building-level text messages. Teachers, club sponsors, coaches and other groups may continue to use Remind 101. However, to ensure that you are receiving important updates from principals and the school district, please opt in for the SchoolMessenger text service.

    How will Lindbergh use text messaging?

    The primary use for Lindbergh Schools will be school closures (such as snow days) and emergency communication. Parents will receive very few district-level text messages.

    Will I be charged for the Lindbergh text messages that I receive from SchoolMessenger?

    SchoolMessenger does not charge recipients for the text messages that they receive or send to the short code; however, wireless providers may charge for individual text messages depending on the plan associated with the wireless device.

    What does it mean if I texted YES to 68453 and I received an error message?

    If you receive what appears to be an error message similar to one of the following, it most likely means that short code text messaging is not enabled on your wireless subscription plan:

    • Service access denied
    • Message failed
    • Short code may have expired or short code texting may be blocked on your account
    • Does not participate

    These replies DO NOT indicate that the wireless provider can’t receive messages from SchoolMessenger. Rather, they indicate that the mobile device does not have short code SMS texting enabled for that number. This is sometimes disabled by default on company provided cell phones. To address this, contact your wireless provider. (Note: Providers sometimes use various names for this type of texting service (e.g. short code, SMS, premium, etc.). If you simply ask about text messaging, your carrier may assume you are referring to person-to-person. Therefore, be very clear to refer to “short code” text messages. Most TV programs with a voting component use short code SMS messaging (e.g. American Idol, Dancing with the Stars, etc.). Using an example such as this can be a way to clarify the type of texting service you want to enable.)
