I sort of had a bad break-up with an ex and her sister eventually blocked me on her phone. However, she and I have started talking lately and we would like to become friends again, but we can only talk on Facebook because I can't text her. She's on her parents' cell phone plan so she can't call and have it unblocked herself and she can't ask her parents because they despise me. I'm getting a new phone soon and could probably get a new number with it, would that allow me to text her again? I'm not entirely sure how blocking works on phones.
