Tired of getting unnecessary calls

You need to contact Tmobile to change your phone number, there may be a fee to get a new number and there's no guarantee you won't receive these types of calls since the numbers are reissued 90 days after numbers are canceled.

The 1st call I received when I came on board here was for the previous owner of the number. I still get calls for them some 3 years later. Just a FYI

If you explain the situation, they usually remove the fee to change the number but there still will be a user support fee.  Sometimes blocking the numbers these callers call from can help as an alternative.

Getting a new phone number won't solve your problem. You'll just get bogus calls from different people and different robos. Get a spam blocker and you should see a noticeable decrease in these bogus calls. Also, block anyone who erroneously calls you. This won't end all misdials or robocalls, but it helps a lot. At least it has for me.
