Having trouble sending TXT to another phone?

If you’re trying to send a TXT message (also known as a text or SMS) but you’re receiving an error or the message just sits in your outbox and won’t send, follow the instructions below for a solution.

If you’re able to send TXT but the recipient isn’t getting them, check out ‘Why aren’t TXT messages I send being received?’.

Try these things first

Restart your phone

Switch your phone off and back on to refresh your network connection. This fixes a surprising number of problems.

Check for outages

Check the Network Status page to see if there are any known network issues that might be causing the problem.

Check coverage

Use the Coverage Checker to make sure you’re in a Vodafone coverage area. The Coverage Checker will also indicate if the signal there is strong enough for indoor and outdoor usage, or outdoor usage only.

If you’re in a covered area but have very low or no coverage bars, or your phone displays SOS, no service or emergency calls only, run through our troubleshooting guide for some additional tips.

Then try these things:

Try making a call

This’ll check whether it’s an issue with your whole service or just your messaging.

Account status

When you try to make a call, do you hear a recording that says your outgoing calls are currently barred? If your calls and TXT have been barred because of an overdue account, get in touch.

Insufficient funds

If you’re on prepaid, when you try to send a message do you get one back from SYS-ALERT with the text “Transaction Failed - Insufficient funds”? If so, check your balance by calling or texting 1512 to make sure you’ve got enough credit to send the TXT.

  • If you don’t have enough credit, you’ll need to recharge to send the message
  • If you‘ve got enough credit, are you overseas roaming? Check our roaming troubleshooting page for help

Premium TXT

Are you trying to send a message to a number that starts with ‘19’? If you’ve blocked access to Premium TXT on your service, you’ll need to remove the block so you can TXT the number.

TXT barring

If you’ve placed a bar on your outgoing TXT through your phone or by dialling GSM codes, find out how to remove it.

International roaming

Are you overseas? Check out the international roaming troubleshooting guide for some additional things to check.

Message centre number

If your phone allows you to make changes to your message centre number, make sure that it’s set to '+61415011501'.


Message format

If your phone’s message settings have an option for message format, make sure it’s set to 'text'.

iMessage on iPhone

If you’re using an iPhone, is the message enclosed in a blue bubble? This indicates that it’s trying to send the message over the internet as an iMessage rather than an SMS so you’ll need to make sure that your mobile data or Wi-Fi is on and working. If you need further help, check out Apple’s iMessage troubleshooting guide.

If you’d like to send messages via SMS rather than iMessage, here’s what you can do:

  • For an undelivered iMessage, tap the message and select Send Text Message
  • If you’d prefer to only send messages via SMS, go to Settings > Messages and toggle iMessage to off
  • You can also opt to automatically send messages as SMS when iMessage is unavailable by going toSettings > Messages and toggling Send as SMS to on

Free up space

Make sure your inbox and sent messages folders aren’t full as this can stop you from sending messages. You can make some room by deleting old messages.


Is the message being sent as an MMS?Some phones will convert very long text messages into MMS rather than sending via SMS. If you’re having trouble sending MMS, check out our troubleshooting guide.

Try a different device

Try your SIM card in another phone. If it works, this indicates there’s something wrong with your phone. If it doesn’t work, it’s likely to either be related to the network or your account.

Some other things you can try

Network selection

Check that your phone is set to automatically select a network.

Network mode

Try switching your phone’s network mode to 2G or 3G only to see if this lets you send a message. If it doesn’t make any difference, remember to switch it back to auto mode when you’re done.

Software/device issues

Issues with your phone’s software can affect its ability to send TXT. If your phone is running slowly or isn’t performing how you’d expect, here are some things to try:

  • Check it there’s a software update available for your phone. Software updates often contain bug fixes for performance issues so installing the latest update may fix the problem
  • If no update is available, try backing it up and restoring it to factory settings. You’ll find instructions to restore factory settings on many phones in our interactive user guides

Next steps

If you've checked everything above and are still having trouble with your service, get in touch. If you’re able to provide the following, it’ll help us investigate:

  • Your device model
  • The street address/es where the problem is happening
  • The time and date the issue first started (state if it’s AM/PM, and to the closest minute if you can)
  • Do you know of any other Vodafone users that are experiencing the same problem in your area?
  • Any other information that you think could be helpful
