Required data plan for the Gravity 3, Gravity T, or MyTouch 3G Slide?

I recently checked T-Mobile's website to view their phones and noticed how certain phones mention a required minimum $15 data plan. The Gravity 3 and T and the MyTouch 3G Slide did not have anything mentioned. Does anyone know if they require anything? The reason I ask is not because I believe the site is faulty (though that it a possibility), but I heard that the Slide required a plan. Since the site does not say so, I am beginning to have suspicions about how legit the site is. Anyone know?

Yea Its Required, They Add It To Your Plan Days After Purchased (If Purchased Online)
Or They Force You To Add It During Your Puechase (Purchased By Phone)
Unless You Pay $400-600.

I Called One For The Slide And They Data Wasnt In My Plan.

The Gravities Are Considered Texting Phones.

haha, what about the Cliq (mytouch slide's not bad either)? It's touch with a keyboard, plus it's android. Of course, it requires a data plan.
But, if you call in a Tmobile employee (who's nice), he/she might be able to either cancel your data plan or change it to a different plan (i.e. texting). Then, just use Tele's proxy to surf the net and facebook, and wifi if you're in a hotspot.

Yea, definitely. I called in and changed sister's G1 data plan to unlimited texting.

Oh right, the $20/month family texting? If you manage to contact a really nice or lenient employee, try your luck.
I've also heard that some people pretend to "change" phones (putting sim-card into an older phone), and explain that they just don't need the data plan anymore, because the phone (as in a Behold) doesn't require one. You just need some info on your old phone to verify that you are using it and the employee will more often than not cancel the data plan.
Remember, androids have wifi, plus Tele's proxy still works w/o data. (Sis is using a Tmobile G1 and TmobileX works!)

i also read on a webite about my touch phones and the other ones that you need a sim card with a data plan to make it work and after that just switch to your regular sim card and you should be fine, im not 100% sure about it but my brother in law is going to give me one and i will try it and if it works i will let you guys know

Get a dataplan phone on craigslist and block it internet access
