Got unwanted calls very quickly after porting the number to T-Mobile. Probably the next day, if not sooner. They probably sold my number to scammers.
Really early I got an unwanted text from Facebook. I don’t give this number to anybody, other then my mom. Could be somebody just entering numbers, to try and see which ones are valid. Does it notify them if you click either of the links? One says you can unsubscribe from SMS. I deleted the text.
That is why, I’ll never give Ultra Mobile money again.
