Why Are My Text Messages Not Being Delivered?

Top 5 Reasons Why Your Text Messages Are Not Delivered

Whether you're trying to send a personal SMS message to a friend or a business associate, or using a service like DialMyCalls to send SMS messages to high volumes of people, you've probably run into issues with your text messages not being delivered.

While DialMyCalls takes steps to avoid this, there are still a few rare situations that can cause SMS message delivery to fail.

In this article, we'll take a look at some of the most common causes that text messages may not be delivered, so that you may better understand how to best use DialMyCalls, and ensure that your messages are always delivered to the appropriate people.


Invalid Numbers - Top 5 Reasons Text Messages Are Not Delivered

1. Invalid Numbers

This is the most common reason that text message delivery can fail. If a text message is sent to an invalid number, it won't be delivered - similar to entering an incorrect email address, you will get a response from your phone carrier informing you that the entered number was invalid.

There can be quite a few reasons for this. For example, all messages being sent to U.S. telephones must begin with the country prefix "1" - if the international country prefix is not added, the message may fail to deliver correctly.

Other causes of invalid numbers include attempting delivery to landlines - landlines cannot receive SMS messages, so delivery will fail.

And, of course, SMS messages may fail if an individual's phone number is incorrect, disconnected, or otherwise invalid.


Carrier Filters - Top 5 Reasons Text Messages Are Not Delivered

2. Carrier Filters

Similar to email, some cell phone carriers have implemented filter systems that can block spam, phishing attempts, and other unwanted messages. One of the primary ways that carriers block spam is by separating "A2P" and "P2P" messages.

P2P messages are messages sent between individuals - and they always have a valid alphanumeric senderID. These messages are likely to be delivered without being filtered.

A2P messages are messages sent from mass texting applications. Some carriers will "filter" these messages, and prevent them from being sent to individuals, in an attempt to prevent spam.

To avoid this, DialMyCalls uses advanced A2P routing to send messages through A2P-enabled routes. However, some messages may still be blocked if they contain certain keywords, though this depends on the specifics of each individual's carrier.

Tips on Getting Started With an SMS Marketing Campaign

SMS Text Message Marketing Tips

The cell phone has evolved into much more than just a phone. It provides you with access to music, video games, your social networks and of course instant advertising. With the high probability that an SMS text message will be read, businesses have begun using them as a way to draw in new customers.

Businesses have quickly learned the value of text messaging as a marketing tool. This is an inexpensive way of reaching thousands instantly with just a click of the send button. Yet like email marketing, a business must ask permission of the consumer first before they start sending special deals and event invites via text message.

Building an opt-in list is a must if you plan on using a text message campaign to build your business. You don't want a random list of names, but rather a database of interested customers where you can personalize messages based on what you know about them. This is not nearly as hard as you think with a carefully crafted plan for gathering opt-in numbers.

Use DialMyCalls And Comply With New 2013 TCPA Rule Changes


As of October 16, 2013 the FCC and TCPA (Telephone Consumer Protection Act) have revised the rules in place regarding unwanted autodialed and/or robocalls.


We met with the FCC and are under the impression that the majority of DialMyCalls members do not need to worry much when it comes to the new TCPA regulations as they have been and will remain in compliance. Members such as churches, non-profits, sports leagues and other organizations that utilize our voice and text message broadcasting service to send out "informational calls" need not worry - the new changes directly target telemarketers and sales calls.

You should still make sure that you have expressed permission when calling members of your school or organization and always have an opt-out procedure in place. This way people who no longer wish to receive your messages can be removed from your contact lists and added into your DialMyCalls "Do-Not-Contact" list.
