The good news?
Most of these issues have simple solutions!
In this post, we’ll walk you through 20 common reasons behind undelivered texts and provide easy-to-follow tips to troubleshoot and avoid these hiccups in the future.
20 Reasons why text messages are not delivered
There can be several reasons for your text message not getting delivered. We shall discuss some of the prominent reasons.
🛑 Recipient is roaming
When the recipient is traveling abroad and using a different network (roaming), delivering SMS can become challenging.
This occurs due to technical compatibility issues between networks or restrictions in the recipient’s plan. Messages may fail or face delays if international messaging isn’t supported.
✅ Solution:
Ensure the recipient’s number is in the correct international format (with the country code). Verify with your service provider if your plan supports global text messaging.
🛑 Recipient blocked number
If the recipient has blocked your number, your messages won’t be delivered. This is typically a personal decision, and indicators might include undelivered texts or calls going straight to voicemail.
✅ Solution:
If you suspect this, attempt to contact the recipient through alternative channels. Respect their choice if they’ve blocked your number intentionally.
🛑 Technical carrier issues
Network outages, server downtime, or maintenance by your carrier can prevent SMS from being sent or delivered. These issues can be area-specific or broader, depending on the carrier’s situation.
✅ Solution:
- Check your carrier’s service status for ongoing outages.
- Restart your phone to re-establish the network connection.
- Ensure you’re in an area with strong network coverage.
- Contact customer support for further assistance.
🛑 SIM card inserted incorrectly
A poorly positioned or misaligned SIM card can disrupt your phone’s connection to the network, preventing SMS from being sent or received.
✅ Solution:
- Turn off your phone and remove the SIM card.
- Inspect and properly align the SIM card according to the phone’s instructions.
- Reinsert it securely and restart your phone.
🛑 Corrupted message cache
The messaging app stores temporary files in its cache, which can sometimes become corrupted and disrupt SMS functionality.
✅ Solution:
- Go to your phone’s settings and locate the messaging app.
- Clear the app’s cache (this won’t delete your messages).
- If the issue persists, clear the app’s data, but note that this may remove your saved messages.
🛑 Outdated phone software
Using outdated phone software can lead to compatibility issues with messaging services. Old operating systems may lack the necessary updates to support the latest SMS protocols, resulting in delivery failures.
✅ Solution:
- Check for system updates in your phone’s settings.
- Install the latest updates for both the operating system and messaging app.
🛑 Unlawful content in text
Messages containing prohibited or unlawful content, such as hate speech, explicit material, or fraudulent offers, may be flagged and blocked by carriers or regulatory authorities to comply with laws and protect recipients.
✅ Solution:
- Avoid sending content that violates regulations or policies.
- Review your text to ensure it adheres to acceptable use standards.
🛑 Text reported as spam
If your number or message content has been marked as spam by recipients or flagged by carriers, future texts may be blocked automatically. This often happens with repetitive or unsolicited messages.
✅ Solution:
- Limit the frequency of messages to avoid appearing spammy.
- Personalize messages to establish trust with recipients.
- Use trusted sender IDs and comply with anti-spam regulations like the CAN-SPAM Act.
🛑 Incorrect phone number
Text messages won’t be delivered if the entered phone number is invalid, disconnected, or formatted incorrectly. This is common when a country code or specific number pattern is missing.
✅ Solution:
- Double-check the phone number, including the country code.
- Ensure there are no typos or errors in the digits.
🛑 Excessive P2P messages
Peer-to-Peer (P2P) messages are subject to limits set by carriers to prevent spam. Sending a high volume of messages within a short time frame can trigger restrictions, leading to delivery failures.
✅ Solution:
- Space out your messages to stay within carrier limits.
- If high-volume messaging is essential, consider using an Application-to-Person (A2P) service designed for bulk messaging.
🛑 Do Not Disturb list
If the recipient has enabled a “Do Not Disturb” (DND) setting or registered their number on a DND list, incoming messages from certain numbers or types of content will be automatically blocked.
✅ Solution:
- Inform recipients about the messages they might miss if they are on the DND list.
- Ensure your messaging falls within the allowable timeframes or categories permitted under DND regulations.
- Use alternative communication channels if necessary.
🛑 Insufficient account balance
For prepaid accounts, sending a message may fail if the sender’s account balance is too low to cover the cost of the SMS. This is a common issue with pay-as-you-go plans.
✅ Solution:
- Check your account balance before sending messages.
- Recharge your account to ensure sufficient funds for messaging services.
🛑 Service restrictions applied
Service providers may impose restrictions on your account due to various reasons, such as exceeding daily messaging limits, violating terms of service, or unpaid bills. These restrictions can prevent texts from being delivered.
✅ Solution:
- Contact your service provider to understand and resolve any restrictions.
- Ensure bills are paid on time and usage stays within set limits.
🛑 Network congestion
During peak usage times or in areas with limited network capacity, message delivery can be delayed or fail altogether due to congestion in the carrier’s network.
✅ Solution:
- Resend the message after some time or during off-peak hours.
- Consider using a messaging service that provides delivery status updates to track message delays.
🛑 Sender blocked by recipient
If the recipient has manually blocked the sender’s number, messages from that number will not be delivered. This is a common way for individuals to avoid unwanted communication.
✅ Solution:
- Respect the recipient’s preferences and avoid sending repeated messages.
- If necessary, confirm through alternative communication whether the block was intentional.
🛑 Invalid number format
If the phone number is entered incorrectly, such as missing digits or incorrect country code, the message cannot be delivered as the carrier cannot identify the recipient.
✅ Solution:
- Double-check the phone number for accuracy before sending.
- Ensure the correct international dialing format if sending to a recipient abroad.
🛑 Expired service plan
The recipient’s mobile service plan may have expired, disabling their ability to receive SMS messages. This is common with prepaid accounts or plans that require periodic renewal.
✅ Solution:
- The recipient needs to renew or recharge their mobile plan to resume receiving messages.
- If possible, confirm through alternative channels that the service plan is active.
🛑 Phone switched off
If the recipient’s phone is turned off or in airplane mode, the message cannot be delivered until the device is switched back on and connected to the network.
✅ Solution:
- The message will usually be queued for delivery once the phone is turned on.
- Wait and try resending the message later if it remains undelivered.
🛑 Poor signal coverage
Messages may fail to deliver if the recipient is in an area with weak or no network coverage, such as remote regions or underground locations.
✅ Solution:
- Wait until the recipient moves to an area with better coverage.
- If applicable, use alternative communication methods like Wi-Fi-based messaging apps.
🛑 Carrier-specific restrictions
Certain carriers impose restrictions on message delivery, such as limiting the number of SMS messages a user can receive within a specific timeframe or blocking messages from unverified sender IDs to prevent spam.
✅ Solution:
- Ensure the sender ID is registered and verified with the recipient’s carrier, if applicable.
- Avoid sending bulk messages in a short period to bypass carrier limitations.
Tips for better connectivity to avoid text not getting delivered
While network issues and technical problems are common, there are proactive steps you can take to ensure smoother communication.
Beyond addressing basic issues like outdated software or poor signal, optimizing your phone and network settings can enhance connectivity significantly.
