A friend of mine has AT&T using a Blackberry with an Unlimited Data plan. She recently downloaded and installed Windows Live Messenger. According to AT&T, she has to pay extra for using WLM.
I have an unlimited data plan with Verizon and am not being charged for using WLM. Can anyone confirm that AT&T charges extra for WLM?
I just got my BB last Wednesday, but I don't think AT&T charges for Live Messenger. Everything, except for text messages (SMS), should be included in the data plan (emails, internet, instant messaging, etc).
The $20 are for unlimited SMS. Windows Live Messenger should be included in the data plan. Double check this with another AT&T representative. My guess is that the first one confused SMS and WLM.
If WLM uses text: $20.00 messaging unlimited plan. -- You can be on the $5.00 200 or $15.00 1,500 messaging plan, as well.
Not sure how WLM charges, exactly, as I've never seen it on a bill. But it's my presumption that only the IM client that AT&T provides charges as text and the rest are data. There are a few exceptions.
AT&T doesn't cover the programs of 3rd parties, so be sure to check their details.
WLM as well as Yahoo Messenger, both used Data from the carrier not SMS or MMS to send back and forth messages, know this becuase I am a long user of both 3rd Party App.
