How to fix a new iPhone sending multiple text messages

If you are wondering why is my iPhone sending multiple text messages? then we have the answer and the solution.

There is nothing like the joy of a new phone until you have to go through the rigmarole of setting up all the apps access again, which has become an arduous task thanks to our reliance on facial recognition negating the need to remember passwords. 

There can also be an issue with new iPhones if you have swapped service providers and are keeping the old number. What happens here is you receive a new phone linked to a new number, and if not set up correctly it can cause issues.

One such problem is sending multiple text messages that you are completely unaware of until someone tells you. But the good news is it’s an easy fix. In most cases under settings/phone, it has your number listed. If this is still the number that came with the phone and not yours, this will be the problem. What it is doing is sending from both the numbers, so it could be sending 2,3,4 or more copies of the same text.

It’s often mistakenly assumed it is the carrier who is the issue here, and in some ways that is correct, but it’s just a setting on your phone. To be clear, this is only the fix if you have bought a new phone and it’s more common if you have switched carriers or service providers.

The full steps to fix an iPhone sending multiple texts are:

  1. Turn off iMessage (setting/messages)
  2. Correct number in settings/phone/my number
  3. Turn iMessage back on (setting/messages)
  4. Ensure it is sending from the correct number (setting/messages/send & Receive)

While these are the directions for an Apple iPhone, this fix should work for any android providing it’s the same scenario.

So, if it’s not the case that you’ve bought a new phone with a different contract provider, who sent a phone with a temporary number, then what else could be the problem?

You might want to try to reset all network settings in general/settings/reset/reset network settings. Be warned, this will wipe your wifi password so you will have to add that again.

You can also try a hard reset, which is like rebooting a computer so loses no data or causes damage. This is often the first advice from all customer support as it restarts the operating system, which checks for faults and ensures all vital functions are running.

To hard reset an iPhone varies on the model, but usually, it involves pushing the power button and the volume up button and holding until you see the Apple logo.

How to hard restart an iPhone

The style of the camera on the back is the biggest giveaway on what model you have, and the different resets vary on button placement. If it has a home button at the bottom of the screen, you have a 6s or below. 

iPhone 8 or iPhone SE (2nd generation), iPhone X, iPhone XS, iPhone XR, iPhone 11, or iPhone 12

Press and quickly release the volume up button on the left of the phone, press and quickly release the volume down button, then press and hold the side button on the right for about 3 seconds. Release when the Apple logo appears.

iPhone 7

Press and hold both the volume down button and the Sleep/Wake button at the same time for about 5 seconds. Release when the Apple logo appears.

iPhone 6s or iPhone SE,5,4,3

Press and hold both the Sleep/Wake button and the Home button at the same time for about 5 seconds. Release both buttons when the Apple logo appears.




  1. 100!!! This fixed my problem. I switched providers and kept my number. The temporary number was in the settings.

    Of all searches, this is the only article that had the solution!

    Thank you!

  2. Bravo, this fixed it.

    The problem occurred when switching to a new provider, from the very outset of using the new sim (with the added delay of waiting for the old number to be transferred over)

    Calling Vodafone, they had indicated that it was to do “with iMessage/Facetime”, and asked that I turn them off, reboot etc, but that didn’t work.

    This worked.

    Interestingly the problem was only when texting Android phones (“green” texts, they would take ages “sending”, and people would be replying to the texts while they were still being “sent” (green line moving across the top)), and not iphones (blue texts).

    Following the procedure above, there was NO number, and so putting in the mobile number fixed the problem, as indicated above.
