Anyone using Captivate on T-Mobile USA?

I like the Captivate better than the Vibrant. Will it allow me to use 3G on the T-Mobile network?

I believe you would only get edge on at&t.

Technically it's the same type of network...

no, only EDGE. They have different 3G bands.
T-Mobile = 1700 MHz
ATT = 850 and 1900 MHz

we can use captivate in china with unicom

I have a Captivate on Tmobile.
Can confirm it's only Edge

I always snicker when I see these threads. T-Mo GSM =/= AT&T GSM. Yes there are common frequencies that all GSM phones use, but each carrier always has their own 3G frequency. None are shared.

While yes there are different GSM bands and yes T-mobile uses different GSM bands than AT&T, mostly all phones are quadband GSM nowadays and thus support but AT&T and T-mobile's GSM network. Even US triband GSM phones still has both AT&T and T-mobile's bands.
3G is where is it different. Not all phones support both T-mobiles and AT&T's 3g bands. Very few actually do. The Samsung Vibrant (another Galaxy S phone) supports T-mobile's 3G bands and can be changed in the service mode to support AT&T's 3G as well.
The Captivate is not the same. The Captivate can only support AT&T's 3G network and not T-mobile's 3G network. It will work on T-mobile's EDGE network.

No they have a different bands for 3g, just because they use Sim cards doesnt mean it can run 3g on both networks

Your wrong, the captivate is AT&T so you can 3G with AT&T and only Edge with tmobile

I'm also using the captivate on T-Mobile but can confirm that it's only on edge.

same situation with the nexus one. cant interchange or you can only get Edge

niceties of 3G
Wrong thread. I apologise!

I just bought a Motorola Cliq (MB200). In Dominican Republic there are only 2 companies with 3G service. Claro Codetel (850Mhz) and Orange Dominicana (900Mhz)
Claro Codetel sells the Motorola Cliq for 3G usage on their network, branded to them of course.
The Cliq I bought is T-Mobile branded.
Is there ANY known way to debrand and have access to the 850 band for 3G?
I ask this question because I saw how it can be done on the Motorola Defy with a service flash found here, so I believe it should also be possible with my Moto Cliq.
I would really appreciate any input on this subject.

Shouldn't you really be looking in those forums and not one for a Galaxy S phone?

Sorry, only did it because there were talks about other makes. I didn't realise it was a "Galaxy S Only" thread.
How do I delete my post?

I can get HSPDA over here in Malaysia.
Actually, both T-Mobile and AT&T phones work here. (2100Mhz 3G band)

Only phone mentioned here was the Captivate. Which is what this fora is for.

Is EDGE service bad? the reason I ask is that I'm planning a trip from Nova Scotia to British Columbia, and going to be drive through the states. Cheaper Gas/Food/Lodging. you get the picture. I have a Captivate from Rogers which is unlocked and was thinking about getting a T-Mobile SIM card to use the Day Pass unlimited internet. However I don't understand what edge means and if this is a good thing or not. LOL
Thanks

Well at&t just bought t-mobile so maybe there will be a combining of signals?

They haven't bought, they are attempting to buy.
DOJ and FCC still have to approve it.
@OP
No, the Captivate was designed to only be supported for AT&T 3G. It does have the 2100 band, which T-Mobile 3G uses, but T-Mobile uses both 1700/2100 for upload/download, so if you don't have both, it locks you into 3G.

Anyone tried to flash a Phone with 1700 enabled?

[Q] T-Mobile 4G Support

Hi There!
I was just in the US for 9 days, and bought a 30 day prepaid plan thinking that because it said I could have 4G I would actually get 4G Speeds. I was only able to get Edge Speeds anywhere I went, and it was pretty horrible.
I logged 2 support chat incidents the first guy was clueless, the second person said they don't give 4g speeds to non T-Mobile provided devices which I thought was pretty crappy.
Is there a software workaround to allow 4G speeds on Android devices purchased from other providers? My phone is an international unlocked device (NZ) and I can get H+ Speeds in Countries like Australia with no issues.
Anyone who could shed some light would be appreciated.

If it was a T-mobile prepaid card that was probably your issue. T-mobile utilizes different frequencies (AWS 1700 band) than almost all other GSM carriers. So if you do not have a t-mobile branded, or a pentaband phone you are only able to get edge speeds. Next time get prepaid AT&T and you will be good to go.

Yah it was a Prepaid Simcard and then a $30 card from Walmart delivered Electronically. I forgot to state I was using a Galaxy S2. Hard to comprehend it not supporting the 4G considering it's a device T-Mobile sell (Though it has slightly different spec's in terms of screen size and button configuration so potentially it could I guess support additional bands.

The international SGSII (I9100) and the AT&T SGSII (I777) do not support T-mobile 3G or 4G. The Skyrocket and the T-mobile SGSII (Hercules) are pentaband phones that support both AT&T and T-mobile 4G. The reason for this is the Exynos processor which does not support the AWS bands. That is why the skyrocket and hercules come with the snapdragon processor.

Thanks for the reply, at least now I know. ATT doesn't seem to have anything similar to T-Mobile in so far as you get 5GB 4G, unlimited calling and texting for $30, are ATT generally more expensive?
Thanks.

Att is generally more expensive yes. But as someone already mentioned, Tmobile uses aws band which is different than almost all others for 4g. So you have to weigh your options

3g on ATT with Galaxy Relay?

So, my phone is rooted and unlocked.I pop in my sim card, put in access point info that was in my old phone that got 3g (desire z/g2) and I only get edge. Am I missing a step? Did Tmobile block att bands for 3g use in the USA?

I figured it out. Network mode was set to GSM. When it was switched to GSM/WCDMA 4g came in great. Not sure why that would be, as ATT uses GSM only, but there you go for anyone that's searching. :good:

Do you mean 3G came in when you switched to GSM/WCDMA? Its my understanding this phone, despite its name, can't actually get 4G but rather a somewhat faster version of 3G when 4G is switched on (online it seems to have the unofficial title of 3.5G).

As i understand it what the phone companies call 4g is not quite actually 4g. Its 2 channels of 3g which gives a net speed in the 4g range. But 4g lte is actually a 4g connection, which the relay doesn't have.

Meaning the Relay 4G won't be able to access AT&T's 4G connection.
I'm more concerned with it being able to access AT&T's 3G connection. There isn't enough 4G LTE coverage for me to really be concerned with a phone that can't access it. In 2 years times, YEAH, but for now, no, I just want decent 3G.

It shouldn't have a problem, as long as it's unlocked and you've set up your APN properly. I've moved my T-Mobile service to an LTE-capable LG Optimus F3, and put an H2O Wireless SIM into the Relay (H2O is an MVNO that uses AT&T's network). AT&T's HSPA+ works fine on my Relay.
The labeling of HSPA+ as "4G" was pure marketing BS; T-Mobile started with that, and AT&T followed suit. I suppose that dual-carrier HSPA+ reaches into 4G territory from a speed standpoint, but I've never seen DC-HSPA+ outside of T-Mobile's network.

I've seen H20 at Best Buy, for some reason I thought it was an MVNO of T-Mobile. I was going to go with the AT&T GoPhone.

I've read about T-Mobile's marketing "trick" but I didn't realize AT&T did something similar.
Well like I said, once I get this phone I should be fine for a good 2 years just using 3G and data. That should give the market time to catch up in the 4G department, by which time I'll be ready to move on to another phone anyway. Thanks for the info. :good:

Yes, "H+" (aka 42Mbps 3G) works fine on the Relay with AT&T Go Phone. It's what my wife is using, and it works fine. Faster than my 21Mbps HTC One X on Go Phone.

Yeah, I bought my wife's for $140 as a manufacturer refurb.
No way do I want to swap my HOX for a Relay, just saying her 3G is markedly faster than mine.

lol alright cool, understood. Well I'm ready to go to the Relay 4G. Love my Epic but its time. GSM here I come.
And I see you're from San Diego. I was there briefly just to catch a plane, but I always wanted to go back to visit. If you live there and 3G on GoPhone works just fine, I should be good. :good:

[Q] Will the Verizon HTC ONE M8 works on AT&T?

Hi there,
I just got my verizon htc one m8 but I was wondering will this phone works with at&t sim card? Can I receive AT&T 4G LTE signals?
Any helps are welcomed.
Thanks in advance.

No, the verizon m8 runs on the CDMA network whereas the ATT m8 runs on GSM. Sorry man

Wrong... It does have GSM to fallback on but you will only get HSPA+ at best. No LTE

As far as I'm aware, HSPA+ is just a slightly faster 3G.

HSPA+ is about 4-10mbps download in my area versus about 1mbps down with 3g.

All in where ya live I guess and which provider you have. Sometimes my HSPA+ is quicker than my T-Mobile Lte...

I'm thinking about using an upgrade on a flip phone I have on Verizon to get this phone.
How hard would it be to get it to work on Straight Talk and since they use AT&T's network, would I be able to get HSPA+ too?
Thanks in advance!

hspa and hspa+
hspa is 3g 850mhz 1.5mbps tops and hspa+ is "4g" 1900mhz 5-20mpbs tops which is really like a 3.9g theres a story behind this but im only answering the question which is which so pretty much this device is ready for either bands just check who's got those bands and you are ready to go ohh by the way no LTE if it isnt with verizon peace im out im batmaaaaaaaaaaaaan!

Because Verizon’s 4G LTE devices use SIM cards, that means many of them (the global-ready ones, anyway) are compatible with the regular 3G/2G GSM bands used everywhere else in the world (no LTE, however). When traveling, simply pop in a prepaid SIM card, configure the APN settings with the network you’ll be using the phone on, and boom. You’re up and running on 3G. Same goes for AT&T in the US (again, no LTE because of incompatible bands).

It does get AT&T LTE, I have a GoPhone account with AT&T and get LTE with my M8. Only in some areas, get about 70% hspa, and LTE the rest, just depends on your location and the AT&T LTE bands used in your area, but the M8 does get LTE

How to Convert Verizon M8 to AT&T

Hello,
I have a Verizon M8 that i'm using with AT&T. Is there a way to convert my Verizon M8 to AT&T so that I can get LTE? Or can I at least flash the AT&T radio? I noticed this video shows a method for converting Verizon M8 to Tmobile https://www.youtube.com/watch?v=6GhybCyd4Pg He is getting Tmobile LTE with Verizon M8 no problem.
If someone can point me in the right direction that would be great!

This phone doesn't have the bands for At&t LTE. Best you would get is HSPA+.

Yes I know it doesn't have compatible bands for AT&T LTE. It doesn't have compatible bands for Tmobile LTE either, but someone demonstrated how to convert it so now he's using the Verizon M8 and is able to get Tmobile LTE without a problem. So there seems to be a way.

I figured it out. For anyone else out there that has a Verizon M8 and are using it on AT&T, you can convert your phone to the AT&T variant. I'm getting LTE but not constantly, it switches between LTE and HSDPA but it's staying mostly on LTE. Yay!

So how did you get it to work ? On the verizon forum all there is, is for converting to tmobile lte and nothing on converting to get at&t lte. Also what lte bands of at&t are you running on ?

Hey there. I posted how I did it somewhere in the AT&T forum. I'm not sure where the post is though as it's been a few months and I don't have the M8 anymore. I sold it and bought a One Plus One, then sold that and bought a Note 4, so that was a couple of phones ago.
