NEW (7/14/10):

Do you know? I found many website but I can’t see imformation for me. And now, I feel happy because your imformation is very useful. Thank you very much!. 

Do you think this imformation? About  personal estimation, I see this review is fantastic. It take for you necessary knowledge. Thank for share!

The 300 MB is in reference to wireless data roaming. The whole 5 GB/300 MB thing is more for connection cards. Connection cards have a 5GB cap, however, you are only allotted 300 MB for attempting to access data while roaming off of the Sprint network. While cell phones do not have a 5GB cap, they do have the 300 MB of off-network, domestic data roaming guidelines in effect.

Today (8/16/10) looking at the Epic 4G plan information I see that they have changed this picture again. The 3G monthly download limit still says "All you can stream, browse, email, chat, watch and game while on our network" but now they have added a reference number 2 which states at the bottom in small lettering "With the Premium Data add-on. 3G plans have a limit of 300Mb roaming usage. Monthly download limit applies to 3G/4G phones, not 3G/4G Mobile Broadband devices".

So does this mean now that there is a separate limit without the Premium Data? That's what I'm lead to believe...

I think that's just to cover themselves when someone says they weren't aware of the extra charge associated with the "Premium Data" phones. There is no limit on data usage on any phone, it's just that on the EVO and Epic, you'll be required to pay that extra $10 fee. That reference point number 2 is to inform you of the fee for the Premium Data add-on.

Yeah, I kinda figured the same thing too (I should have added a note of sarcasm to my last post). What's interesting is that the reference point isn't attached to the 4G line. Which kinda makes sense if Sprint "can produce the gigabyte for cheaper" as Dan Hesse says. All that data surfing on their 3G network taxes the carrier more and they only have a limited amount of bandwidth available to subscribers so they're charging the data heavy phones more.

But once everyone has 4G and the data rate is cheaper I don't see Sprint's argument for charging the extra $10 fee. Especially when I can buy a 4G data card and surf till I run out of battery on my laptop and download so much more data than I ever could on my phone. Then it goes back to Sprint's argument that their phones are enhanced and you're paying the $10 for the premium experience of the phone. Which to me seems ludicrous because each phone is better than the old version and in my opinion I should not have to pay my carrier for an upgraded CPU or screen, something I own.

The old page specified a limit on other networks of 300MB. The new limit removes any mention of that information. Do you know what the policy is for data NOT on their network, i.e. roaming data limits?

I think the fee is for the truly unlimited, no 5gb data cap that every other phone has. Im willing to pay the 10 for ny cap

There is no cap (and has never been for years) on phones. The cap only exits on data cards while in 3G. In 4G, data cards also have no cap.

Go to sprint.com and find the "Sprint 3G/4G USB Modem 250U by Sierra Wireless" and step through as if you're going to buy it. 3G/5GB or 4G/unlimited. Apparently, they made this same mistake(?) with all of their 4G devices?

That IS correct. USB modems and other data-cards still have a 5GB cap.

Thank you for this! If a Sprint person is reading this, all I want is to be told the truth. I think that Sprint has made many improvements. All you have to do now is create a logical statement to explain your $10 fee. How about this: "$10 Cell Phone WiMAX Use and Expansion fee." By calling it this, you can logically justify charging the fee to non 4G customers, OR you could give us something cool: How about you find a way to give us a Skype app (with free Phone to Skype calls of course)?
Just some thoughts. I know that sprint is in a bind and that they need to make money, but that is no excuse for lying.

Thank you for your hard work and dedication in getting this fixed I greatly appreciate it. However I would like you to call the Sprint executive and ask them about the Language that they used defining the fee. The called the fee an Add on. In business we all know that an Add on is something extra you are paying for that is optional. Sprint has wrongly called this fee an Add on when it is not optional. We think of an Add on when you are getting a topping on your pizza or if your paying 500 dollars additional for text messaging etc. BUt if you dont get the Add shoudlnt effect your service plan. Sprint used this Language calling this an Add on confusing customers, prospect customers, thinking they can get the Evo for 69.99 and if they want to add something additional like insurance etc it is an Add on. I feel that any customer with sprint can legally get out of the contract for the false pretense that this required fee is an add on.
I would love to see Dan the Ceo for Sprint buy a dozen of dunkin donuts for 7 dollars then the clerk tells Dan there is an 5 dollar add on, Dan will say um okay just want the dozen donuts I dont want anythign extra.. the clerk saying well the add on is required. Dan saying huh? this makes no sense.. Clerk if you want the donuts its 13 dollars? Dan I just want the dozen not the add on? See Dan how this can be misleading and completely unethicical to call something that is an add on that is required.

LOL...I like your analogy. I see it more like Dan goes to get a dozen jelly donuts but the clerk tells him that if he wants them there's a mandatory "premium jelly add-on". Dan says but no one else charges a premium fee for jelly and I've ordered jelly donuts from you guys before and never paid a fee either. Clerk says, yeah but now our jelly offers a premium taste experience so everyone has to pay the extra fee. (Clerk gives Dan a free sample). Dan says, that's funny the jelly kinda looks and tastes the same as it did before the fee. Clerk says, maybe but trust us this is "premium" jelly, it's so good it'll make you want to eat 3 dozens donuts all by yourself so we charge the fee to make sure we can keep up with demand. Dan says, um...it's the same jelly and uh...no it's not really enticing me to eat more of it than I normally would. Clerk says, oh but trust me you'll be hooked, everyone will, and before you know we'll be all out of jelly if we don't charge this fee. Dan says, @#$& it, keep your stupid jelly, I'll just go to krispy kreme instead.
