I bought a 8gb Iphone back in July and for some reason I was never entered in for a 2 year agreement so my old agreement was still in effect and I was eligible for an upgrade. Well a few days ago I bought a 16gb white Iphone for myself and gave the 8gb one to my wife. Well she already had the medianet unlimited plan for 15 dollars. I just put her simcard into my old iphone and she got internet up with no problem. Today we both get a text message with ATT that her data plan was incompatible with her phone and that we should call today to avoid any expected overages in data charges with my account. How do you guys think I should handle this? Thanks in advance.
