As has been pointed out, receiving voicemail (that is, someone leaving you a message) consumes minutes. Do you receive a lot of voicemails over the course of the month? Or, particularly long voicemails?
I've never heard of a carrier charging when someone leaves a message.
You may not have heard of it but that has been standard practice amongst US carriers since the beginning of time.
I have the identical experience and will take it up tomorrow with T-mobile at our local T-M store.
What happens when your 5GB of data is up? Do you get throttled or you can't have data usage any longer?
That doesn't seem to happen for me on the $30 100 minute plan. I called my N4 from my work phone and left a rambling voicemail. When I checked my minutes that night, it was the same as in the morning. Calling to listen to the voicemail from a VOIP line didn't eat up any minutes either.You may not have heard of it but that has been standard practice amongst US carriers since the beginning of time.
You get throttled, but I can't remember to what. Maybe EDGE?
