I will admit that I'm not too swift when it comes to understanding data usage, but could someone please tell me what the abbreviations stand for on my bill. In particular; MBRA, SMH, and MMH. I can see that they're listed at the top of the box, but the definitions are as "Greek to me" as the abbreviations.
So if someone could explain them in short, simple, layman's terms, I would really appreciate it!!
