Unable to send text messages

[jhy2025]

Hi, 

I'm having trouble sending text messages ever since I have set up roaming following this guide. 

Since then, I have performed a network reset and also turned off iMessages but still unable to send any text messages. I have also tried to follow this troubleshoot guide here but it doesn't work (dialling *#*#4636#*#* doesn't do anything).

Can someone help me please? 

Thanks.

@jhy2025  Setting up roaming on a device by changing the APN should not interfere with text messages specifically.

When you mention turning off iMessages, I'm wondering if you have also ported in a number recently. Sometimes using iOS, it helps to not only turn off iMessage, but also FaceTime and then restart them after a short while. This is linked to the phone 'remembering' the first allocated mobile number.

You didn't say exactly what happens when you try to send a text. also, are calls and data working correctly? Have you done a Network Status check to ensure no local issues with a mast?

@MSF Yes I have recently moved to Smarty in March. I have turn off both iMessage and FaceTime, the phone number displayed under Mobile Service > My Number is the right number. 

Calls and data are working correctly. Text messages just couldn't be sent out, I get the "Not Delivered" error. I don't think it has to do with local mast issue as I have been travelling around London and Essex and having the same issue.

@jhy2025 Thanks for further explanation - I was just exploring possibilities.

I wonder if there is an issue with the port process. You will need to have a web chat with Smarty Support so that they can investigate for you.
