1) Is your phone rooted or just stock?
2) Have you tried updating profile and PRL?
3) If you do have root (as it's required for most of these things), see this link:

There are a few good suggestions there. You can also take your phone in to Sprint, and have them reprovision it. That might help.

 

Note the Verizon...

 

Sorry, skipped over that in the subject. So, what exactly are you doing to use Verizon?

 

Are you trying to roam on verizon/use their data? There is supposedly a method to do so but I have not seen it yet. Currently the only methods I have end up on verizon 2g.

Check out the thread akazabam linked above. There are two key steps in there that will increase data speeds 15-75%

 

I am not entirely certain we understand what you are trying to do lol

 

you are using an evo on verizon ? your service is through verizon?????

 

Not really sure how to help you on this one. You make the first I have read that has done this. (haven't really looked)

My experience is pretty much limited to sprint phones on sprint service

 

Do you have a guide or instructions of some sort that you followed to get your phone on verizon?

 

While i realize its been quite some time since you posted your problem, you never posted your solution.

I am having a similar issue and would love to have something other than my inconsistent 3g speeds, all sub 40kbps down.

 

welcome to the forums!!!!!!!!!!!!!!!!!!!!!!!!!
try this fix:http://androidforums.com/evo-4g-tips-tricks/280082-major-solution-fix-your-slow-3g-speeds-evo4g.html. hopefully this will help you.

 

Thanks for the warm welcome!

Yeah, i have tried the fix(es) posted in the link you posted, as well as flashing older radios (Pri prl nv wimax etc) to numerous different versions.

Girlfriends phone performs flawlessly 500kb down+, whereas mine is lucky if it makes 40kbps, and is typically 15-25k. (Same location)

The only difference i can find between the two phones is in ##debug#. In the EVOD section, "requested data rate" on hers (as well as my brothers evo) fluctuates around 200-400. Mine sits at 0 all the time.. never changes.

All other settings seem to be matched perfectly. Sprint has done numerous ##data# resets (over the phone and in person), they re-installed my HTC software in store, reprovisioned both in person and over the phone and said my phone is fine. I held my phone and her phone up together, tapped the same utube on each phone, hers played through, mine got a network error and closed out. I also did a speed test, hers showed 600kbs DOWN, 400kbs UP. Mine was 27KB Down 300KB UP. The "tech" at the sprint store said it was because we have different phone numbers, and sprints towers are congested.


Pissing me off to be honest with you.

 

Think i may call sprint tomorrow and demand a new phone be shipped to me. We can swap em out and be done with it.
