I have a pre-paid Straight Talk phone from Wal-Mart. My old one broke, and I just got a new one. The new one is a different make. Anyways when I was just trying to understand the phone and its features a problem spoiled everything for me. Actually my girlfriend uses her Yahoo to text me because she doesn’t have a phone. It worked fine when I had my old one, but as soon as I switched service from one phone to the other, the texts from Yahoo quit going through. She is sending them to my number, but they aren’t getting to my phone. She even tried to use AIM, and that didn’t even work. Can anyone tell me what exactly the problem is?
