SIM card and phone changed

I had to change my simcard and phone after my phone broke. Just put a new SIM in my old phone.
Now my phone is sending already 3 times in 1 day a SMS to my wife that my sim card has changed and a SMS with my location and cellphone id’s.
And is this going to happen again when i buy a new cellphone?
How can I solve this problem? stop these messages?
