The benefits of instant messaging capabilities on a cell phone are undeniable: wherever you go, all of your IM buddies are just a keystroke away. Can’t hold an extended conversation because you’re working? IM. Have a quick question that’s not worth a phone call? IM. Too loud in the bar to hear anything? IM.
But for all the convenience it offers, the technology also carries a hefty price tag. Adding instant messaging to an existing service plan will add anywhere from $10 to $20 to a monthly bill with popular carriers such as Verizon, AT&T and T-Mobile. Multiply that by many months, or in the case of families, many phones, and it really starts to add up.
