[Q] 3G speeds on T-mobile

I am aware that T-mobile uses different 3G bands than does ATT. Most phones when unlocked are left to crawl on edge and cannot get 3G speeds when switched to another carrier. Being as the Captivate and Vibrant are essentially the same phone, would this be an issue. I've been on the G1 since it came out and I really don't like the iphone look of the vibrant. Was planning on getting a Captivate and unlocking, but not if I'll loose 3G.
Can anyone running an unlocked Captivate tell me if they're getting 3g on t-mo??

I would say no.

I believe it was engadget that said the Captivate can get t mobile 3g speeds but not vice versa.

Nope you can only get 3G on the vibrant unlocked to att not the captivate you can only get EDGE speeds on tmo with the captivate.
So basically:
Vibrant: tmo 3G
Att 3G
Captivate: tmo EDGE
Att 3G
So yes it might be an issue for you lol

Doesn't look like a bad phone but I wouldn't trade my vibrant for it lol if you want a phone worth getting wait for the glacier.

Only thing I really don't like about the galaxy s's is lack of trackball. .. I really use that alot. Also physical keyboard is a plus while not a must for me.
Sent from my HTC Dream using XDA App

I hear you on the track ball. I almost went with the HTC Aria for that reason. But the Samsung GS phones are just so damn cool it's unbelievable! Really...... get the TMO version of GS and if you miss your track ball after 2 weeks then exchange it.

[Q] When 4g comes out for Captivate will we have to get new phones?

Can we just flash the LTE Modem or will we have to get new phones?

our phones do not have the required hardware to go 4g. i could be wrong but i doubt it. but who cares, by the time at&t actually gets a real 4g, we should all be ready to upgrade.

LTE and HSPA are different. As long as HSPA is pushed then we can go to the max of the phones hardware.

Another amazing post. They walk among us.

Was your old EDGE speed phone capable of getting 3G speeds? X-(
Of course ypur going to need a new phone with a 4G sim card.

What are the max speeds on HSDPA/HSUPA? And just how much are we going to miss?

Miami if you're not going to be helpful in Q/A then why post?
For 3G/4G you need to talk tech not blanket terms it would be easier to know what exactly you are asking.
HSPA+ LTE are the competeing tech one being a new tech (LTE) and one being an advancement of current tech (HSPA+).
Captivates can do um 7M using HSPA (double check gsm arena or the wiki or the manual for the numbers) so any upgrade to the network the device will top out at the max speed the device can support.
Sent from my SAMSUNG-SGH-I897 using XDA Premium App

Max speeds for HSPA are theoretical. TMO said they would push it up to and over the 50M level while currently upgrades to networks have it at 14-21M though because of the way it works you will not get those speeds real world.

Is it possible to make a rooted captivate show 4g instead of 3g

And its possible to actually get At&t 4G speeds with an i9000 based rom/kernel/modem

no. hardware does not support 4g.
you can however get hspa on I9000 modems, which is up to twice as fast as regular 3g.

technically ATT doesnt have real 4G, so HSPA is pretty close to what ATT calls 4G

I doubt it 'cept the corporate AT&T people. They seem to be rolling them out 3-4 cities a year. So who knows. In OKC, it might be 3 months from now or 20 years from now.

The Thrill is not a LTE phone. The Thrill will never get LTE speeds. The 4G for the Thrill is HSPA+. The reason people call it faux G is that its not that much better than 3G. Check the coverage map online, you may already be getting 4G speed (according to att), and not know it. I saw an increase from my captivate to the Thrill, about 50% increase, but not enough to actually notice on a daily basis.
Att announced today their first LTE phones, skyrocket and vivid.

When you got the phone, did you just put the old sim card in from your old phone? That is what the at&t store did when I bought mine and I was not getting very good speeds. Went to the store around the corner from me and they replaced my old sim with one that said '4g' on it and the Rep said something about not getting hspa+ on the older Sims. Not sure about his reasoning, but I do get anywhere between 4-8mb down now. I can never seem to get over 1.08 up speeds though. It acts like there's a cap on it the way it is so consistent.

Just pulled it out and checked it. Plain AT&T sim. The one initially put in here was from my LG eXpo and came from my Incite from 2009. The Rep said that it needed a '4g' sim to actually get the speed. So he put a new one in. Can't complain as it worked.

I think I have the same one, lol. Was just mashing sure it didn't say 4g because they told me it was a 4g chip.

Verizon 4g lte on Sprint!?

I know this doesn't sound possible hell I Dont believe it myself but I am in LittleRock Arkansas where Sprint has NO 4g, I'm up here at work bored so I flash the 1000 Verizon prl, I unlock my SIM card (don't think that mattered , I didn't put a SIM card in). I forced roaming on my phone and I about had a heart attack when the 4g showed in my notification bar!! I thought it may be wrong but I ran some speed test with and without it. The catch is I lost voice. How is this possible?

Highly doubt it... Verizon is operating LTE on 700 mhz (the latest article I saw was that in 2015 they will plan to shift some EVDO to LTE on 1900). The Sprint HTC One only supports LTE on 1900.
Just because Sprint hasn't officially announced LTE in that area doesn't mean they haven't been doing the update. They have a ton of location that have spotty (and even complete) LTE coverage that aren't even officially on the LTE list.

The n.ispsn is something new also.

Lol! Look I'm not saying it's undoubtedly Verizon's 4g, I'm just saying that normally I Dont get 4G even when forcing roam. I flash the modded Verizon Prl still no 4g. I force roaming and boom 4g and no voice.

I've played with some different PRL's some allow 4g, some don't. But on all the ones that allows it I can't download apps from the app store. Updating my profile loses 4g until the reboot.

Force roaming causing 4G detection isn't anything new, actually. If you put the device into LTE mode only, it achieves something similar. The device would much rather stay on Sprint service if at all possible and will take a weak LTE signal if it can (even if it would normally prefer a nearby Sprint tower providing 3G coverage).
The speeds you've posted are in-line with a Sprint 4G test/slow rollout and would frankly be rather laughable on Verizon's 4G network-- if we get around the obvious hurtle that it is not physically possible for your phone to pick up Verizon's LTE, full stop.
Eliminate what's impossible (by hardware) and we have a series of at least possible alternatives.

Oh, *that* one. I used to use it all the time until it stopped giving me Verizon 3G. Now all I get with it is 1x. I would try it, but I'm running 4.3 now and don't want to nandroid back to a Sense ROM just to confirm that it's not working.

Sprint 4G on initial release in an area or an a tower is very wonky. It's off and on, slow and only works at a short range. Just be patient and you will get it really soon. They just activated it in a couple areas where I live also. They tend to put them near Sprint Corp stores.

It's probably Sprint I just can't [email protected]$king believe it. As impossible as my theory sounded, I thought it was more probable than Sprint bringing 4g to Arkansas. Here are some more speeds. I honestly don't know how they compare to Verizon's, I just wanted to show I got some consistent 9-10 range before it went to ****...

Why is it unbelievable that Sprint is bringing 4g to Arkansas... They HAVE TO do the NV update on every single tower that broadcasts Sprint Signal. It is cheap as dirt to just add the LTE hardware into the NV station once the NV upgrade is completed. This is a nation wide requirement since they are about to do some wonky ass things on the 1900 MHz PCS bands (when they start to reallocate their allowed bandwidth to different techs, it is an across the board FCC license).

I'm from Arkansas too and have been keeping up with the 4G there because that's where I travel to every chance I get. Jonesboro has sprint lte and it's been planned for little rock and Fayetteville to get it for months. It was only a matter of which day. I'm surprised it took them this long. But it was expected. I'm so happy to hear this wonderful news
