That's exactly what I did, I waited too long as well and didn't receive the text until the morning. After calling and being on hold for almost an hour, I got through to an agent. I still had to call my old provider though. Anyways! It'll be solved so...
I did not receive a text from old provider no, I took out public mobile sim and put the old one back in, turned on and off a few times and no text. I'm not sure if I can receive calls, no way to verify at this time, I received one text from a contact...
