[Q] Samsung Vibrant 4G SPECIFICATIONS

I know the original vibrant was a pentaband phone, supporting AT&T's 850/1900 networks as well as t-mobiles 3g networks....
Can anyone confirm the 3g bands on the new Vibrant 4g?
Will there be fast 3g 21mbps for 850/1900 on the modem chip also? ( or 4g whatever you want to call it, in my book its just faster 3g..)
someone enter the debug screen and check which bands are available...
cheers!

HSPA+ 21 only works with T-mobile, AT&T doesn't use an AWS band, in this case is 1700/2100Mhz.
Someone may have been able to 'trick' the vibrant into using a basic UMTS band on AT&T, but I never heard of it, let alone heard that the Vibrant supported AT&T 3G. The Vibrant has GSM.support for them (2G), I haven't seen anything else.
Where's the supporting documents that people have been getting At&t 3G with a T-Mobile Vibrant?

Trust me.... I'm using a vibrant on at&t with 3g. It does support the wcdma 1900 band. There is alot of evidence of this...heck engadget made a post about this... google it!
Edit: What I was trying to ask is if the galaxy s 4g supports the 1900 wcdma that the original vibrant supported....

That would work....hopefully the galaxy s 4g can be unlocked the same way the previous galaxy s phones could.

In my research I have found that 4G is not backwards compatable with 3G. Someware I read that companys are putting 3G and 4G chips on the new 4G phones to bridge the gap between the 3G chip ability to handle voice and the 4G chip being able to handle data. I can't say for sure if SGS4G has both chips. It's a know issue that the 3G SGS misses calls when connected to a laptop because It does not handle data well in combination with voice. That's why I upgraded to the 4G. I don't think Its going to make a lot of difference until TM gets their HW in place with a backbone that can support it.

Samsung Galaxy S 4G 1900 MHz WCDMA
I bought my Samsung Galaxy S 4G at a T-Mobile store in San Francisco. I subsequently upgraded it to the latest firmware provided by T-Mobile using Samsung Kies.
I usually use WCDMA only mode because GSM causes awful buzzing sound when I use it in my car (I have a FM transmitter connected to my phone).
Anyways, I was curious to see if I'd see AT&T, so I searched for network (still under WCDMA Only mode), and it found both AT&T and T-Mobile.
I pressed *#197328640# in the dialer, and then went to the debug screen/band selection to look at available bands, and it actually does have 1900 WCDMA.
It shows
GSM 850, 900, 1800, 1900, WCDMA 2100 (FDD I), WCDMA 1700 (FDD IV), WCDMA 1900(FDD II).
I don't know if AT&T SIM would work since my phone is locked but I can report back once I get it unlocked.

EDIT: Reading an old post of mine, I realized that my memory played a bad trick on me. My tests DID work on 1900 WCDMA and DID NOT work on 850 WCDMA, just opposite to what I wrote earlier in this post. --sorry

I don't think it would work. For reference, here is a side by side band comparison between my Vibrant (tested 3G on AT&T) and my coworker's SGS 4G (locked, untested).
The essential band here is the 850 1900 WCDMA, but the "overflow" 850 WCDMA is missing and I couldn't make it work anyways (I'm in Houston, maybe it is not switched on here).

My understanding is that AT&T usually uses 1900MHz for 3G, and in certain cities where they don't have enough bandwidth in 1900 MHz like NYC and SF, they use 850MHz.. so you could still get by with only 1900 MHz, no?

Yep, thats what I have heard as well. Now one thing of note. When I tested my Vibe, it only worked on the 850 1900 WCDMA band. Could not make it work on the 850 no matter how hard I tried. I'm in Houston for that matter and maybe this 850 WCDMA is not enabled here.
This was my test: http://forum.xda-developers.com/showpost.php?p=9958501&postcount=14

I'm currently unlocked on AT&T and i'm on 3G. I ALWAYS have an issue with upload speeds, but otherwise download speeds are just fine.
I attached four photos, of the available bands with my CURRENT galaxy S 4G unlocked on AT&T.
Also, a speed test I ran. That download speed is WAY higher than average because it was taken when the network was under the lightest usage possible, late at night.

Oh wow, over 5Mbps download on AT&T?
Are you on AT&T's 4G (HSPA+) or 3G?
I'm supposedly on T-Mobile 4G (my phone shows 4G when I download/upload), but I don't ever get 5Mbps. I get usually something around 2~3Mbps down and 1Mbps upload. I'm in the Bay Area.
I went into phone debug page, and one of the screens says HSDPA[0], HSUPA[0]. It also says network status: HSDPA (sorry I don't have the exact info on me right now).
Am I really just on HSDPA, not HSPA+? Is there a definite way to find out what my phone is using? Thank you.

Technically I'm on HSPA+, though this phone doesn't even cover all of the "necessary" bands.
Look, to edit what bands you're on go into the market and download SGS Tools.
Then, go into the first line (Secret Codes) and hit Band Selection.
I'm on AT&T so I'm not sure what bands you need, but you can manually select them in there.
To check the band you're on, go to GSM Status in the "Secret Codes" page again.

Oh I know I'm on 1700/2100 MHz because that's the only frequency (AWS) that T-Mobile uses for WCDMA/UMTS/4G/3G.
I downloaded Phono, and it says Network Type is HSDPA. Shouldn't it say HSPA+? I'm just wondering if there's an easy way to tell if I'm really on 4G (aka HSPA+) as opposed to 3G.
I actually messed around with debug settings last night so I'm worried that I screwed it up....
Thank you!

Which debug settings did you change?
And as for Phono (which I've never even heard of/used until now), my phone says HSDPA as well, which, quite frankly, makes no sense. I guess you can technically get speeds of around 5MBPS on HSDPA but it's not typical.
You should easily be able to tell whether you're on HSDPA or HSPA+ with the 4G/3G connectivity icon. in your status bar.
Now, I'm no expert, but hopefully that answers your question.

I played around with GCF settings. When I go into debug mode, there was something about choosing Rel.6 or Rel.5 or cancel settings.. And then also, if you do *#3214789#, you can enable/disable GCF Mode.. which I have no idea what it is about....
Thanks!

Hmm...that's awfully strange.....
I can't find anything about it anywhere....
Try restoring using ODIN yet?
I mean, if the phone is that messed up since you messed with that setting.

I put my friends att sim in my unlocked sgs4g to test and the 3g sign came up by the bars as well as the att operator logo didn't really test out speeds but im guessing that the 3g sign wouldn't have came up unless it was really picking up that frequency.

4g service question

Hey guys,
I am a little lost on this. I was looking on the Infuse and thought about getting it and unlocking it to use with tmobile and was wondering if i would get 4g speeds on it. Here is the bands i pulled off on AT&T's website for the phone:
GSM/EDGE:GSM/EDGE 850/900/1800/1900 3G - UMTS/HSDPAHSPA 850/1900/2100 4G*HSPA+ with enhanced backhaul
According to this, it should work. Am i mistaken?
Thanks

Um, why would you think it would work? Do you see UMTS1700 in there? I don't.

I thought it used 2100? I don't know much about the bands. Just started reading on who supported what.

tmobile uses mainly the 1700 band for 3g/4g. they also own the 700 band but i dont believe they use it. att is mostly on the 850 and 1900 bands. european and asian bands are typically 900 and 2100 so they dont really use those bands to keep unlocked phones off the network. the infuse does not work for 3g and 4g on tmobiles network, sorry.

ahh ok. that makes sense now. I've mainly stuck with tmobile phones, except tried an iphone a couple of times. but att has some cooler phones that i thougth i might want to try, but guess that won't happen now . I use the net on my phone alot, so it would be an issue.

Actually AT&T's weird bands have nothing to do with keeping unlocked phones off their network, just the fact that 2100 MHz wasn't available in the US for any carrier.
UMTS2100 is for international roaming, as it's the standard UMTS band in almost every other country.

T-Mobile uses 1700 and 2100, and you NEED both for 3G/4G to work.

i though the att bands were the same as rogers, bell, and telus use in canada? and the same as used in some other countries in the americas and in places like new zealand. i wouldnt exactly say att has the weird bands in this case.
maybe in a year or two att will merge networks with t-mo and you will have a huge selection of compatable phones.

its the same as rogers in canada, and telstra in australia. i belive bell and telus are cdma.

the bell vibrant is an i9000 and the telus fascinate is a t-mo vibrant, the modems all work on the captivate. trust me they are all gsm networks and fully compatable with att phones.

[Q] What US Carrier is the International GTab 7.0 plus (P6200) fully compatible with?

Sorry for what is probably a stupid question.
I am thinking of buying an International version of the 7.0 plus (P6200) but I'm having a hard time figuring out which US Carrier, if any, (AT&T, T-Moble or Verizon) is fully compatible with the table's supported frequencies.
Any help in pointing me to the carrier, that will allow the tablet to get 3g data and allow the tablet to make phone calls, would be greatly appreciated.
Also, if you are using a P6200 in the US, I would be interested in what carrier you use, your opinions of the carrier and your opinion of the tablet in general.
Thank you

Over 140 views but no replies.
Does no one know the answer or is the question so simple it is basic knowledge I should already know?

I'm not familar witht eh international model but I can tell you that it won't work with Sprint or Verizon as they are CDMA and not GSM. So that leaves T-Mobile and AT&T and it would depend upon what frequency the GTab7+ recieves, is it tri-band (850, 1800, 1900) or just a single band? AT&T uses 850/1900 MHz and T-Moblile 1900 MHz for 3G service. I would assume that it would be tri-band as are so called "world phones".

TMo also requires UMTS1700.
So almost surely it will NOT get 3G service on TMo. That's why there is a special Tmo variant.
Don't know about AT&T

Thank you for your reply!
Here are the listed frequencies for the tablet
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
it appears that it supports all the frequencies for AT&T and T-Mobile. I guess my confusion is I can't tell if the tablet will support 3G or just 2G (wouldn't be worth it if all I could get is 2G).

Ahh, that is what I was looking for. As much as I dislike them, seems I will need to go with AT&T if I get this tablet.
Thank you very much, both of you!

Sorry I got a little confused between tabs and phones. Verizon uses EV-DO (CDMA based) for 3G and AT&T is HSDPA (GSM based) at 1900 MHz. T-Mobile uses 1700 and 2100 MHz for 3G.

warning, if you plan on using as phone and tab, at&t may want to make sure you are on tab data plan as well an it could be pricey for both.
with that being said Im using this on att with voice and unlimited grandfathered smartphone data. havent heard a word from them. I pray it stays this way. I will fight them for it.
conclusion: best mobile device in the world right now IMHO, until 7.7 comes out.

P6200 and iPhone SIM
Hi all,
just to make sure...
If I get the P6200, can I just pop my iPhone 3gs SIM with unlimited data plan (as long as I don't use it too much)?
I saw someone said they can do that on the 7.7 thread but I wanted to make sure the AT&T iPhone SIM isn't restricted to iPhones somehow.
Thanks

I have GT-P620900 from the Philippines and I am my tablet in the US now. I tested using at&t sim card and it works when I tried making a call using sim card (gsm).

Hi Neogrin,
With the posted frequencies:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
it will work perfectly for 3G (HSDPA/HSPA+) speeds only on AT&T. You should get 2-4 Mbps downlink, or maybe even more with a good signal on AT&T.
Unfortunately for T-Mobile (whom I also prefer over AT&T), it will only work on their 2G network, at EDGE speeds, which would be about 200 Kbps if you are lucky. Actually, EDGE speeds are good enough for twitter, facebook, and a bit of surfing, but would be frustratingly slow for YouTube or downloading apps.
The Tab 7plus will NOT work on Sprint or Verizon as their CDMA, LTE, and WiMax networks are different technology from GSM and HSDPA and thus not compatible.
Internationally, the 7plus should work on almost any 2G or 3G network, with maybe a few country exceptions here and there.
BTW if you decide to activate your 7plus on AT&T, I can share a bit of experience. I received a Tab 7.7 3G this week, with a similar frequency list to the 7plus. (Unfortunately, it also lacks the "AWS" 1700/2100 band for T-Mobile). I went to an AT&T store today to activate the 7.7 on a month-to-month data plan, of US$25 for 2GB with US$10 per each 1GB of overage. They were not able to assign the data plan in their system to me, because the 7.7 3G is not an AT&T device. The same will be true for your 7plus. What they did to get it to work was to take the IMEI number from one of the other tablets they had on display in the store - making sure it was an HSDPA tablet, and not an LTE one - and used that to activate my account. It took them a while to figure this out, but when they did, it worked. Once the account was activated, and the SIM card was in my 7.7, it found AT&T service and I immediately got a welcome text message. However, data did not yet work - for that I had to do one more thing, which the staff did not know about (but luckily I did).
Go into Settings->Wireless and Networks->Mobile Network Settings
In there is an "Access Point Names" item.
Click on this, and you should see some entries. If it's a new AT&T SIM, it likely says "Cingular 410" or "wap.cingular" or something. This would be correct for a phone, but does not work with tablet data plans, so we need to add the correct one.
Bring up the menu, and there should be a "New APN" option. Select this. In the form which comes up, in the "Name" field, enter "broadband" (one word, no caps, without the quotes). In the "APN" field, do the same - "broadband" one word, no caps, no quotes.
Once you've done this, hit the menu again, and there should be a "Save" option. Choose this, and it will take you back to the list of APNs. Now in the list there should be an APN item called "broadband" which you just created. Press the radio button to the far right of the broadband item. It should turn green.
Give the tablet a few seconds, or a minute, and data should start working!
Hope this helps.

Bad ESN Verizon One hd in Canada?

LOL I'm an idiot, was thinking HTC ONE when I said one hd...
Found a really good deal ($170) on a bnib razr hd from verizon with a bad esn on ebay. Didnt really have the time to fully research it before the auction ended so I just took the chance and placed the order.
Did some searching after the fact and have found some really conflicting information. I know the phone would be pretty much useless in the states, but I'm unsure of its usability in Canada? I've herd they would work fine in asia and india so I'm basically curious if anyone knows the extent of how far verizon shares its blocked phone information? Does it extend to Canada?
I've herd on the states you need to have your phone activated onto a network? In Canada we just throw in our sim card and are good to go. Is this a different technology (CDMA vs GSM?). If so assuming the Activation portion of the phone is blocked could the sim card part of it still be open theoretically?
Assuming its possible to work with the bad esn does anyone know if I could use LTE on Bell/virgin?
According to bell it uses LTE AWS 1700mhz and LTE 700mhz and HSPA 850mhz and 1900mhz
According to gsm arena the xt926 uses:
HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 MHz Class 13
Should be fully compatible no? I cant find any information on what class bell uses for their LTE, nor do I know if the class affects anything?

You can unlock it for gsm carriers in the us and its already unlocked for international use. I know with att u get h+ witch is good enough for me on straight talk. I average about 6mps.

Got the phone on the weekend. It works fine on bell/ virgin except I can't connect to lte. Does anyone know of it's possible to unlock lte? According to gsm area the phone should be compatible with lte 700mhz which is what bell uses... Will that radio com thing you guys use to unlock it for us carriers help?

[Q] 1800MHz LTE Band

This phone is the first phone Verizon is selling (except the iPhones) that has the 1800MHz LTE Band (band 3).
When I saw this I was particularly excited as I visit Australia often and that's the band Telstra uses. I am currently in Australia now, and I am unable to pick up any LTE on this phone. I have gone through every possible mode in the phoneinfo app, but none will get any LTE signal.
I am using a Telstra SIM that has LTE service and I put in the correct APN settings.
The only possible explanation that comes to mind is that Verizon is blocking the 1800MHz LTE band from being used, just like the S4 came with AWS but only a software update pushed later on was able to unlock that band. If that were the case, is there any way around it?
Any other ideas why it's not working?

I tested my SIM in the same location in a iPhone and it got lte

Bit of a necro-post, but I asked both HTC and Verizon associates and they said that it should work...so don't know if some bad information has been passed my way or GSM/LTE is just being funky (I do remember reading that has been, or was, a problem)
