Text Alert Services

Text Alert Services are simply services that deliver alerts and messages via SMS text message only.  The One Call Now service allows you to quickly send texts to a list of contacts via cell phone, mobile app, or email.  In addition, One Call Now provides full multi-modal notification channels, meaning you can send voice calls and emails in addition to text messages.

Yes, text messaging is on the rise, but it is only one of several channels available to effectively communicate with a group.  Contacting your recipients using the channel they prefer is a critical aspect of effective notification.  Accommodating a variety messaging preferences and quickly sending tens, hundreds, or thousands of text alerts can be a challenge.  Fortunately it’s one that One Call Now can help you overcome.

Broadcast Text Messaging

Broadcast Text Messaging describes the process of sending multiple text messages simultaneously to a variety of recipients.  This differs from group text messaging in that it generally means the message is being sent to hundreds or thousands of recipients at once, thus the term “broadcast”.

One Call Now’s notification platform will broadcast your text messages to any number of recipients, and help you make efficient use of your time by providing sub-groups and message template features that help you select and send with speed and precision.

Research indicates we check our phone on average 1,500 times a week.

One Call Now - Mobile Notification - Text SMS Notifications


Text Alerts and Push Notifications

People are inundated with information today. When you need to broadcast quickly to a fast-moving group of contacts – Mobile notification is the best tool to cut through the noise and deliver your message.

Broadcast text messages and alerts the way your contacts prefer. One Call Now enables you to instantly send a message to a specific list of contacts, a group, or an individual.

Mobile Notification with One Call Now

Our text message feature provides plenty of character space – 160 to 300 characters depending on the sending method – allowing for somewhat detailed messages that also stay on point.  With a 300-space limit, recipients receive only the most pertinent information.   When you’re direct and brief, your contacts are less likely to miss or ignore an important reminder text.  That’s not always true with voicemail, especially for younger smartphone users.  Studies show users under 30 tend to ignore voicemail messages but check their text messages over 150 times a day.

A Calling App You Can Rely On

To ensure that recipients of your messages won’t get overwhelmed, we created My Call Now, the ultimate mobile recipient app. It gathers and stores messages sent via One Call Now in one place for quick, easy reference and allows your contacts to forward them to their calendar, reducing the likelihood they’ll forget an important event.

The One Call Now Messenger App makes calling and texting from your mobile a snap. Do you need to send specialized text message alerts?  One Call Now is used by thousands of clients to send SMS text message reminders, general text notifications, mass calling to mobile devices, text message alert systems for emergencies, employee and staff notifications, as well as other custom applications.  You won’t find a better mass and group text messaging service with mobile apps, sms alert systems, and text reminder services.  Interested in knowing more?

How Text Alerts Work

Short Message Service (SMS) is an available feature on the  One Call Now service plans. SMS is a text messaging component of web or mobile communication systems, which allows the exchange of short text messages between mobile phone devices.

Because of the potentially high cost of receiving text messages, mobile phone service providers require that phone owners manually opt in and have a means to opt out of receiving these messages. That is, they must take a deliberate action that confirms they will accept text messages from a third party service such as One Call Now. While text messages can typically be up to 160 characters in length, One Call Now reserves 30 characters to provide this required opt-out clause allowing recipients to stop receiving messages at any time.

Text Opt-In

Secure Opt-Ins Managed by One Call Now

When One Call Now receives this Alert text message, we will “Opt-in” your cell phone to receive text alerts and send a confirmation to your cell phone by text. If you are a member of more than one organization using the One Call Now service, you will be “opted-in” for all groups that have your cell number in their calling list. If your preference is to receive text messages for only some, but not all, of these organizations, contact the organization’s group leader or One Call Now’s support team. You will receive this “opt-in” phone call only if your phone number is in a calling list for an organization using the One Call Now service. If you do not respond by sending the word Alert to One Call Now, you will not receive any group text messages from your organization via the One Call Now service.

How To Opt-Out

If you would like to stop receiving text messages, you can opt-out by texting the word Stop to 22300 from your cell phone. Text messages will be disabled to your number. (You can opt-in again at any time by texting Alert to 22300.) If you choose to Opt-out of text messaging, you will continue to receive voice phone calls to your cell phone.

New to Texting?  How to Use Text Messaging

New to Texting? To send a text message, open up the “Menu” on your cell phone and look for the “Messaging” option (this usually looks like an envelope.) Select “New Text Message.” Type in 22300 in the “To” field and type the word Alert in the message field. Note: some cell phones have you type your message first and enter whom you are sending it to second. Receiving text messages is easy. When a message is received, your phone will notify you. Just select to “view” the message. To view the message again, open up your “Menu,” select “Messaging” (usually an envelope) and select “Inbox.” All the text messages you have recently received will be in your “Inbox.”
