- Your number isn’t verified by carriers for mass texting. To combat fraud, spam, and other illegal activities from their networks, wireless carriers require businesses to verify their phone numbers.
- You’re using the wrong messaging type. If you’re trying to send SMS campaigns from a personal phone number, you may experience carrier filtering. This is known as peer-to-peer (P2P) messaging, which is traditional text messaging from one individual to another.
- Your message contains illegal content. If you’re sending text messages containing adult content, drug references, or any kind of criminal activity, your messages will be blocked by the receiving carrier.
- Your links look suspicious. Some scammers use link shorteners to disguise phishing links. Carriers may filter messages with links that look shady, including those that are shortened by third-party apps.

Whenever a human gets involved in data collection, there is bound to be the occasional error. One of the most common reasons for non-delivery is simply that the mobile number (also known as an MSISDN) is incorrect. Either the customer gave you the wrong number or you entered it incorrectly into the database. It’s also possible that the mobile numbe...
Mobile numbers need to be correctly formatted in order for message to be delivered. (This goes without saying.) This often isn’t as simple as it first appears. There are many acceptable formats for a mobile number but a few that don’t work. You need to make sure that if you’re sending a message to phone registered in a different country that you us...
This would seem unlikely as we’re all glued to our phones for hours every day but some folk do keep their phones switched off for extended periods, particularly if they’re on holiday. The message will expire after about 48 hours, so if a phone is switched for a couple of days, it will never arrive.
Most mobile contracts allow all services to work abroad but there are a few contracts that do not permit receiving texts outside your country. When this is the case and a person is roaming, then a message won’t be received.
Most mobile handsets allow you to block messages from any numbers. This typically can’t be set if you are using an alphanumeric sender ID but could cause non-delivery if you have set the sender ID as a reply number. Iphone users also have the ability to filter unknown senders into a separate list. Notification alerts will also be switched off. So i...
Some countries do not permit dynamic, alphanumeric sender IDs. If you send a text to a contact in a country with restricted sender ID regulations, then your message will probably not arrive. Some networks simply automatically switch the sender ID to a random number to allow delivery, others will simply block the text. Countries and individual netwo...
In order to avoid consumers being bombarded by marketing texts at anti-social hours, some countries impose restrictions on when marketing texts with alphanumeric sender ID can be sent. For example, in France, you are only permitted to sender marketing texts between 0800 and 2000. Marketing texts sent outside these hours will be blocked.
Increasingly, networks are implementing anti-spam and phishing filters in an attempt to prevent rising spam problems in some countries. If your message looks like spam or could be interpreted as a phishing attempt then some networks will automatically block the text. Occasionally this means that legitimate traffic containing certain keywords may ge...
Most companies use the GSM characterset to send SMS messages. If your text contains odd characters outside the standard, then your message will be rejected by the network. To allow for the sending of emoticons, messages can be sent using UTF-16 encoding, although this hugely reduces the number of characters per text to just 70. This unicode charact...
Some networks operate a ‘Do Not Disturb’ service which allows users to opt out of receiving any marketing texts. Subscribers will therefore not receive SMS messages if this option is available and activated.
Jun 13, 2024 · Text message failures can occur due to an invalid recipient number, network congestion, carrier issues, insufficient signal strength, message size limitations, or carrier content filtering. Issues with your device or messaging app could also contribute to these failures.
- 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.
- Carrier Filters. Similar to email, some cell phone carriers have implemented filter systems that can block spam, phishing attempts, and other unwanted messages.
- Routing Factors. SMS routing can be a large factor in the successful delivery of a message. While most SMS messages are sent through routes directly to the relevant phone numbers, this is not always the case.
- Incorrect Encoding. SMS encoding is what determines the allowable combination of characters that can be sent. Messages are usually sent using Unicode, which contains 70 characters, or GSM 3.38 – a global standard which allows for 160 characters.
