Code M2MCNG on an iPhone to Nokia for call of 1 minute duration: 49MB of data?
Data details on bill shows as 1 minute, 48MB of data usage (sent, not received).
Googling code M2MCNG is appears to mean: moblie-to-mobile, Cingular.
My Mom is AT&T on a Nokia feature phone. I believe AT&T bought Cingular at some point so that explains the Cingular.
On the bill, the charge is *not* in the SMS/MMS sections (both have no entries at all), it is categorized as "Internet/MEdia Net".
My iPhone shows a voice call at that time of 2 mins, but its SMS/MMS history has no call at that time.
Also, my iPhone, 3 mos old, has never had its usage tracking reset, and outbound data is 55MB total, over three months.
I already called and AT&T, and he said they have no idea what it is. I don't need exact details, but I need to know how 49MB of data can be sent on a mobile-to-mobile, non MMS, 1-minute call. Everyone I talk to says it should be impossible.
Email goes through the ISP, not directly to a phone. FaceTime is not possible over cellular, and even if it were, she is Nokia.
I barely ever send SMS/MMS, I'm way too old for that stuff.
Anybody got any ideas? Any AT&T person can help clue me in?
attaching a screen snap. "DT" means daytime not data.
