If you have changed your phone or swapped sim cards to another handset you might be frustrated to find that you cannot connect to your social media networks or send MMS (picture messages). That is because this probably needs to be set up again.
You may have even received a text message from T-Mobile asking your to set up these services and to reply to 34967 however it sometimes it doesn’t work – the message comes back that it – cannot be sent to this address.
I’m not sure why this happens but it appears to be happening to a lot of people – it is the correct number so it doesn’t appear to be a scam, but this error is happening and people are confused at how to set up their cell phone. T-mobile just say that they are having issues.
All you have to do is go to the link http://support.t-mobile.co.uk/help-and-support/index?page=home&cat=SOFTWAREDOWNLOADS and you can send yourself the correct settings anytime for free. Just follow the onscreen instructions, it takes seconds.
Hope this helps
