How to Fix Excel Files Not Sending via Text Message on iPhone
Product
Microsoft Excel / Apple Messages
Device & OS
iOS
Scenario
Attempting to share an Excel spreadsheet as an attachment in the Messages app to another mobile user.
Observed behavior
The Excel file fails to send, often displaying a 'Not Delivered' error, due to file size limitations, network connectivity issues, or carrier MMS restrictions.
Before you start

Before proceeding, ensure that your iPhone has an active cellular or Wi-Fi connection, and verify that the recipient is capable of receiving iMessages or standard MMS attachments.

Solution 1Recommended

Verify File Size and Network Settings

Check if the Excel file exceeds carrier MMS size limits and ensure your messaging network settings are properly enabled.

Standard MMS text messages typically restrict file attachments to 1MB - 3MB depending on your mobile carrier. If your Excel file is larger, the message will fail to send to non-Apple devices. Additionally, network settings must be correctly configured to allow attachment transmission.

1
Check the Excel file size

Open the 'Files' app on your iPhone, locate your saved Excel document, press and hold the file icon, and select 'Get Info' to verify its size is under 1MB.

2
Enable iMessage and MMS Messaging

Navigate to your iPhone 'Settings', scroll down and tap 'Messages', then ensure that both 'iMessage' and 'MMS Messaging' toggles are turned on.

3
Check Cellular Data

Go to 'Settings' > 'Cellular' and confirm that 'Cellular Data' is toggled on, which is required for sending MMS attachments to Android users.

iMessage vs. MMS: If both you and the recipient use iPhones (blue bubbles), iMessage allows much larger file sizes (up to 100MB). If sending to Android users (green bubbles), strict MMS limits apply.

Frequently Asked Questions

Why does my iPhone say 'Not Delivered' when sending an Excel file?

This usually happens if the file exceeds your carrier's MMS size limit (often 1MB to 3MB) or if you have a poor cellular network connection. Try connecting to Wi-Fi, or send it as a cloud link instead.

Can I send an Excel file to an Android user via iPhone text message?

Yes, but the file will be sent as a standard MMS message rather than an iMessage. Because MMS has strict file size limits, large Excel files may fail to send. Sending a cloud link is highly recommended for cross-platform sharing.

How do I reduce the size of an Excel file on my iPhone before sending?

You can reduce the file size by removing high-resolution images, deleting unnecessary sheets, or compressing the file. To compress it, open the Files app, long-press the Excel document, and select 'Compress' to create a smaller ZIP file to send.
