SMS Texts Not Sending

Over the past couple days my phone has been unable to send texts. Instantly the failed to send issue pops up. However I am still able to receive texts, use and receive calls and my mobile data works. I haven’t changed any settings on my phone or ID account. My phone hasn’t been damaged either.

    Hi ​@ccairns 

    Are you trying to send an MMS text (containing pictures, photos, emojis, GIFs, videos and sound clips.) and not SMS??
    You will be charged to send an MMS text:-
    https://www.idmobile.co.uk/help-and-advice/call-charges

    If you wish to send MMS messages then you also need to ensure that your bill cap is set higher than your monthly plan £ to cover them.
    If you were able to send MMS messages previously then you may have hit your cap limit and now they won’t be sent until it is increased to cover the cost.

    Here are 2 help pages with regards to Bill Capping:-

    Hope this helps x

    Hi

    same issue; last few weeks, sms text messages are received but not sending.

    Not iMessage

    Not MMS message.

    immediately that I send an SMS message (including replying to an SMS), I get told ‘message not sent’.

    iMessage works fine

    calls work fine

    data not an issue

    I’m supposed to have unlimited text messages

    no help therefore in this thread, except people with the same issue get sent a mysterious text message from ID support.

    iPhone 14+, recently ported to ID from O2

     

    thanks,

    Seems to be working.  However data is incredibly slow, if at all - even though I supposedly have good signal and 4g.

    I have exactly the same problem. Texts not working. 
    I’m not trying to send an MMS, they are text only. 
    imessage works fine, as do calls. 
    when I try to follow the steps to update my phone number (same number) - it won’t save. 
    i think I’ve had this problem for a while but not really realised it.

    Hi ​@Paul.1,

     

    I'm sorry to hear you're having trouble sending texts.

     

    As iMessage and calls are working, and you've already tried updating your number without success, we'd recommend contacting our Live Chat team so they can investigate this further.

     

    They'll be able to check the account, arrange a replacement SIM if needed, or escalate the issue to our Technical Team for further investigation.

     

    You can contact Live Chat here: https://www.idmobile.co.uk/live-chat 


    Regards,
