@JudyW this is not something Public Mobile can help. The sim part and the text is a procedure your old provider follows to avoid SIM fraud. However, call your old provider back, some might take a verbal approval on the phone.
Once you sorted that out with your old provider, then call PM porting team to retrigger the porting request. I will send you the porting team phone number in private message. Check your Community inbox on top right
