For months I have been getting an error that comes from +1121611611 and the message content reads "122 Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code. 0605040710000041637469766174653A64743D3135". I have been reading all over the internet and it seems loads of people are having the same problem but there is no solution.
I noticed the common denominator seemed to be people changing carriers. I found two people stating that switching from T-Mobile to ATT caused the problem as it was TMobile sending an internal text to track your Fav 5 members. This meant if you switched carriers the message was getting rejected. Then it appeared a lot of people were getting it when texting friends, no idea what caused this. Finally someone suggested it was an issue with the phone trying to access the prior carriers voicemail. I went into settings>more>application manager then to the TMobile visual voicemail system. I cleared the cache the clicked "turn off" which ultimately deleted the app. I then went to the dialer and held down the #1 key which called my voicemail (not sure if it was Tm or ATT system) and it said my password was expired and I changed it. After doing all of this the messages have completely stopped. I cannot say for sure I know the cause but it appears to be voicemail related. Im guessing after switching carriers the phone still tries to access the previous carriers system. I am simply posting this to help and I am going to post the link back to the on 10-15 websites where people appeared to really be struggling.
