I got my hands on an iPhone 3G today after weeks of being lazy. My wife and I were out the door before 9am this morning. The guy that helped me out with the purchace didn’t really have any answers regarding the difference between the basic data plan ($30) and the enterprise data plan ($45), only that the enterprise plan was for “business people,” which is understandable. Apple takes care of the phone and AT&T takes care of the voice/data plans.
I did a little bit of research on the AT&T website tonight and I found little or no good explanations for the burning question “Do I need this to access my work email?” Seeing as I set up my email via exchange before I did any research, it brought me to the conclusion that no, I don’t need the enterprise plan to access email via Microsoft Exchange. In fact, I did some googling of the topic and found a fairly helpful post by Mike Deoff regarding the confusion and subsaquent shananagans surrounding the enterprise plan.
Mike mentions his confusion in his original post and provides updates with other bloggers’ discoveries regarding the data plan. He writes:
I found a very good explanation on Howard Forums from someone named RF9:
AT&T will not be blocking Activesync. There really is no way to do it.
The $30 iPhone 3G personal data plan is the same thing as $30 PDA personal (for all other PDAs.) And the $45 Apple business data plan is the same as the $45 PDA business data plan.
You can use Activesync on ALL AT&T data plans with windows mobile and Palm OS PDAs as of now. This includes $15 media net, $30 PDA personal, $45 PDA enterprise, $60+ laptop connect, even on all blackberry plans.
So unless AT&T or Apple concocted some way to restrict activesync based on data plan specifically for iPhone, then it won’t be restricted. Furthermore there’s no reason to.
Exchange Activesync is for personal use as much as it is for business use.
The “business” or “enterprise” data plan for $45 will be required if you’re on a corporate paid plan, or if you have a business account. They will consider those businesses and require the business data plan.
If you pay your own individual bill, you won’t be required to get the business data.
If you call AT&T, they’ll tell you “yes, you must have the $45 plan” but those people are just repeating what they were told, which is flat our wrong. It’s nothing new, they’ve been doing it to AT&T reps for years.
Maybe it’s that the people who do the training don’t understand it, or that they’re just being greedy jerks. I don’t really know.
I’ve been following this topic closely for the last two weeks and I can assure you you won’t need the business data. I also know AT&T data plans and pricing very well and for several years and just based on what I know they won’t be trying to block it.
Finally, the reason it’s so vague is for this very reason. They don’t want to come out and say “you can use exchange on personal or business” because they don’t want you to question them when they tell you you must have a $45 business plan to use exchange if you’re a business customer.
They’d rather you just assume you need it and pay for it.
So there you have it. You don’t need the enterprise plan to access company email via Microsoft Exchange. That in itself is available to all iPhone users via the $30 data plan.
