Can't send or receive text message that contain the number 1 between iPhone and Android to and from multiple people.

Hello@brettphil913, we're here to help you

We understand the issue you are experiencing with text messages containing the number "1" not being sent or received between iPhone and Android devices can have several potential causes. 

1. iMessage vs. SMS/MMS: Please Ensure that both the sender and recipient have iMessage disabled (if on Android) or enabled (if on iPhone) when sending messages to each other.
2. Check Message Format:  Try sending messages without any special characters or formatting and see if the problem persists.
3. Try a Different Messaging App: If you're using Google Messages or another third-party messaging app, try switching to the default messaging app on both devices and see if the issue persists. This can help determine if the problem is app-specific.
4. Check for Message Blocking: Confirm that neither of the devices has any message blocking or filtering settings enabled that could prevent messages with specific content from being delivered.
5. Disable Wi-Fi Calling: If you are using Wi-Fi Calling, try disabling it and test if the issue persists when using cellular data for messaging.
6. Reset Network Settings: On both devices, you can try resetting network settings to clear any potential network-related issues. Be aware that this will reset Wi-Fi, mobile data, and Bluetooth settings.
7. Contact Apple Support: If the problem persists and you can reach out to Apple Support for assistance. They can provide guidance for iPhone-specific issues.

I have this exact same issue.  I cannot send or receive texts with the numeral 1 in them from my android phone to iPhone users on AT&T or T-Mobile.

Interestingly, the text "111" made it through.

This has got to be frustrating! I’m glad you reached out; it will be my pleasure to get this resolved for you!

The issue you are experiencing with text messages containing the number "1" not being sent or received between iPhone and Android devices can have several potential causes. Here are some steps and considerations to help diagnose and address the problem:

1. iMessage vs. SMS/MMS: It's possible that this issue is related to iMessage, which is Apple's messaging platform. iMessage works between iPhones and can sometimes cause compatibility issues with Android devices. Ensure that both the sender and recipient have iMessage disabled (if on Android) or enabled (if on iPhone) when sending messages to each other.
2. Check Message Format: Ensure that the message format is not causing the issue. Try sending messages without any special characters or formatting and see if the problem persists.
3. Try a Different Messaging App: If you're using Google Messages or another third-party messaging app, try switching to the default messaging app on both devices and see if the issue persists. This can help determine if the problem is app-specific.
4. Update Software: Ensure that both devices have the latest software updates installed. Sometimes, compatibility issues can be resolved through software updates.
5. Contact Your Carrier: Reach out to your mobile carrier (in this case, AT&T) and inquire if there are any known issues or network-related problems affecting text message delivery. They may be able to provide insights or solutions.
6. Check for Message Blocking: Confirm that neither of the devices has any message blocking or filtering settings enabled that could prevent messages with specific content from being delivered.
7. Disable Wi-Fi Calling: If you are using Wi-Fi Calling, try disabling it and test if the issue persists when using cellular data for messaging.
8. Reset Network Settings: On both devices, you can try resetting network settings to clear any potential network-related issues. Be aware that this will reset Wi-Fi, mobile data, and Bluetooth settings.
9. Contact Apple Support: If the problem persists and you suspect it's related to iMessage, consider reaching out to Apple Support for assistance. They can provide guidance for iPhone-specific issues.
10. Test with Other Contacts: Experiment by sending messages with the number "1" to and from other contacts who use both iPhone and Android devices. This can help determine if the issue is specific to certain contacts or devices.

Did any of these resolutions work for anyone? We are having a similar issue when texting the number 1 to Twilio (our messaging/notifications vendor) since yesterday, 9/27/2023.

I have not contacted Apple support but none of the rest worked. I also had my kid text an android user on Verizon and they were also unable to send the number "1" to each other.

I have had other iPhone users test this with other Android users they know and the same result but as far as I know at least one user was always AT&T. 

Actually, I tested again last night and it was still an issue but now I can text a 1 to my kid. I'll have others try 

It started working for me today as well.
