[Q] Samsung Infuse 4G At&t HSPA+ data working on T-mobile network. - General Questions and Answers

Hey,
I was recently using my phone that i got a couple days ago ( Bought it unlocked at my local Electronics store ) and i popped in my T-mobile sim card and after 1 day I looked at my status bar, I had H+ on the top right corner. I tested it out on my browser ( I was at a park while this happened ) and the data worked fast like on a T-mobile 4g phone. But it later went away after a couple minutes. I was trying to take a picture with my other phone to prove that it wasnt photoshopped or anything but i was too late. Can someone help me on this situation? Is there a way i can keep it at HSPA+? Please don't take me as a cellular noob i repair phones and setup for plenty of people.
Thanks.

That could be some bizarre glitch.

Yeah, thats what i was curious about. I was happy for the moment being, but when it went away i just had to go with it since its supposed to be at edge speeds.

I'm actually really weirded out by the fact that it actually worked at all for a period of time, and that you got speeds at that speed. So the question is, what exactly happened?

Basically, I was in a neighborhood next to the park ( thats the way i get there ) and i was looking at my phone and saw my H+ sign up there so I got pretty excited and tested it out and it was indeed HSPA+. I will go back to the same neighborhood and check again. Also it happened while i was at the gym a couple hours before. Weird stuff.

Probably a bug, sometimes mine thinks it doesnt have a data connection when it actually does, or displays E (for edge) when its actually on 3g
If you catch it happening again do a speedtest - I doubt it will be 4G speeds

I would assume you were seeing an area where T-Mobile has 'refarmed' their HSPA+ network onto the 1900MHz band, which according to Samsung is possible with the hardware.:good:

Refarming makes a lot of sense. And I will definitely speed test it for sure.

If you have "bad" 3G reception...

Try going to your phone and type in *#2263#, go to WCDMA and choose the 850MHz band exclusively and go back and choose all the GSM bands. EVERYTHING except the 1900MHz WCDMA band.
I've noticed that my phone tries to hang onto a one bar 1900 connection than rather switch to a five bar 850 one.

Not every area uses both.
Though it is pretty well known that the non captivate modems show a preference for the 1900 band.

well some areas do and its fun to see if your i9000 modem could be giving you better reception. I know that at school I only get one bar of 1900 and four-five of 850. I expect other people are in the same scenario

Well, your title and original post make no distinction that this info is just for modded ROM users. That's one of my gripes about this place. Yeah, there's lots of great info, but often it is very confusing and little is said about who it is aimed at because the posters assume everyone is at the same level of understanding. I'm not picking on you, specifically.

AT&T LTE Network Going Live This Sunday

http://www.maximumpc.com/article/news/att_lte_network_going_live_sunday
The cities included in this initial wave are Atlanta, Chicago, Dallas, Houston and San Antonio. Although users in those metro areas will still have very few LTE devices to choose from. Unlike Verizon, which has multiple LTE handsets, AT&T has no phones compatible with the new network. AT&T launched a data stick and a portable hotspot for the LTE network last month. The carrier has also started selling a massively overpriced Android tablet, the HTC Jetstream.
sweet im in San Antonio for a little while, now for AT&T to get some phones for me to use !!!
Now if they could hurry up and increase the HSPA+ speeds. I'm still only getting 3.5mb download and 1mb upload in downtown Dallas.... iPhone 3gs gets about the same download speed, although only half of the upload speed.
Come to the other side of the Metroplex. Downtown Fort Worth and I am getting 5-7mb down, 1.1-1.3 up. I can't wait for the Holiday with LTE. That will be SO sweet.

I know the Inspire is not a LTE phone, but just launching the network upgrade has helped me to see vastly improved data speeds. I also know the Speed test app is not accurate, but I have never seen it pull these kind of speeds, especially consistently.
Well, I would like if it came out in Madison soon... (and when AT&T has more LTE Android phones)
Ok I live an hour away from Houston. Do you think I would still be getting LTE? Also do we need a new sim card or anything or does it automaticly happends?

As mentioned, you would need a LTE phone first. But, being an hour away from Houston, I wouldn't run out and buy one when they become available. I live in the outskirt of Houston and HSPA+ is non existent at home. In Houston where I work, as posted, I am just now seeing the true benefit of HSPA+. Probably some bottlenecks from ongoing upgrades being freed up, maybe a little congestion as well.

Knowing how AT&T operates, I'd imagine they opened up more bandwidth to the land-based lines to the area first to make sure their LTE debut went well and you're just seeing some of that extra bandwidth.

I'm not as stupid as you. I know when I'm on wifi. Here is the proof.
Here are some from earlier today. The first two were indoors, a large metal building with offices above on the second floor. The first run was bad, only 2800kbps, but I did hit 4916kbps on the second. I then went outdoors and tested a lil slower than yesterday, but not by much, 6485-7767kbps. I know we can't put too much stock in the Speed Test app, but there is some consistency and I'm getting much higher runs than I had been. Also, it seems to be reading my wifi at home with some accuracy.

Show me where I made that statement. I stated that since the LTE launch, my data speeds have suddenly increased and I'm finally seeing true hspa+, and that is a fact. I provided a couple of possible reasons for this, as someone else cited a possibility as well. I know what you saw. You saw the hosted by Comcast in the screenshot. Lol. Anybody with half a brain would know that there would have been a wifi icon in the status bar if I was on wifi. Next time you open your mouth, try not to put your foot in it. Your little signature says it all. Just because you are in a crummy area, doesn't mean it is like that everywheres.
Check my screenshot of prior tests and tell me if you see any improvement compared to yesterday and today. LOL.

I'm good. I just don't appreciate someone implying I'm either stupid or I'm a liar. It certainly isn't inconceivable that while AT&T was building the LTE network here in Houston, they were improving the backhaul for hspa+. Whatever the source of the improvement, I'm thrilled to see true hspa+ speeds. It is something I never expected to see with my Inspire.

Unlocked ATRIX 2, currently on T-Mobile. Can I get 4g?

My service bars are full but it has an "E" instead of 2g, 3g, or as I would prefer, 4g. Does anyone know if I will have to root my phone? Or what my limits are considering it is unlocked and working on T-Mobile?
Sent from my MB865 using XDA App
Im pretty sure you're gonna be stuck with Edge as in the bands are different for 3G and Hspa
I have a friend that has an Atrix 4g unlocked on T-Mobile, and he has claimed to have gotten a 4g signal in one fringe area. He said that it was very spotty at best but it worked. I suspect it was some kind or roam signal he caught, or he was delusional. But Edge is definitely the best you will get since the frequencies are different. There is no fix for that, it is a hardware thing.
Oh wow... that really sucks. Thanks for the answers though. What if I root it or that still wouldn't be able to help? Edge is pretty ****ty service for such a nice phone, which is why I got it... plus I got a hell of a deal on it lol

Atrix 2 Unlocked No Signal
I have successfully removed the network lock on an Atrix 2 but gets absolutely no signal/emergency calls only with a T-Mobile sim. When I search for Network providers only AT&T shows. I was wondering if the radio was locked for some reason. Anyone else had this problem?
(For those of you who like to throw out the simplest ideas: Yes T-Mobile has service in the area. Yes: I have done a reset and chaged sims etc..)

That was my thought too. What plan are you on? I read that you can use their 30 dallar unlimited plan when you activate a new sim card.
I still have the hope that at some point after the BL gets unlocked we might get a hacked radio kernel of sorts that will allow use of t mobile bands..... The global 2 did something like this to allow use of t mobile...... One can hope.....

You can get 4G on T-Mobile, but only in certain areas as of right now. Pretty soon though, after T-Mobile starts utilizing the frequencies gained from the deal going through, you should start seeing more 4G in more places. But we have to wait and see if it actually happens.

I live in Vietnam, and I have a problem with Vinaphone network, added APN, but can only use HSPA (4G icon).
If I switch to GPRS (E icon), it says connected, but I cannot ping pass.
Other network (Viettel) is normal.
Even if the bootloader gets unlocked I still believe it would be a hardware issue not an issue of the radio software. They use the same 2g frequency so you can still get edge, but when it comes to 3g they operate on different frequencies. Some phones are made with the hardware for both frequencies though. My Samsung Vibrant (Tmobile phone) actually had the hardware to be used on AT&T 3g! The radio software was an issue unfortunately and it didn't switch well between 2g and 3g, tried all sorts of radio software but had no luck back then.
From what people have experienced by taking this phone to AT&T though, its looking like the Atrix 2 doesn't have the right hardware for the Tmobile 3g frequency.
I'm not one to say something is impossible though. Who knows.. maybe through the failed merger of AT&T and TMobile, TMobile was somehow able to gain access to some of AT&T's 3g towers (doubtful), since they did gain coverage through the breakup agreement after the merger failed.

In certain markets, they will get part of the frequency that AT&T uses for 4G. I forgot what bands exactly, but if you do a Google search, you should get more info.

I'm using unlocked Atrix 2 on T-Mobile. And I did get 4G signal when I was in downtown Bellevue, WA. I didn't believe so I ran few speedtests, best I got on Download was 1501kbps, and 1416kbps Upload, and it wasn't roaming. So yes, it works in few places right now.

4G info that I'm HAPPY to report, but it raises more questions...

I am one of the people who have had a hard time getting good 4G service even though I'm in a. great 4G area. Today I noticed that if I reboot my phone in the area I wish to receive 4G service I get a super-fast 4G connection!
Now, that is great news but why can't my phone do this without a reboot? Does anyone know why this happens?
Have you tried simply turning airplane mode on/off rather than rebooting?
No, I didn't and thanks for the idea. But the phone should be able to do this on its own, right?
I have to toggle airplane mode when in a spotty 4g area. I hope a new radio will help with making a more seamless switch.

I'm more curious why I was getting speeds upwards to around 34d/l and 24upload before (just a few weeks ago when they flipped the switch for 4g)... and i'm getting weird but constantly lower ranges from 5-20d/l to 8-15upload...
still faster speeds than 3g here, but just odd...

To be more specific (not sure if you know or are curious) a new radio hopefully will report greater signal for your respective area. New radios typically come with ota updates and users may notice greater data speeds and network signal.

I've been having the same issues within buildings. Definitely a cycle of airplane mode will help once you leave the building and/or have moved locations.

Had the same problem too. I went to another city without 4G and came back home and tried to watch some YouTube. Noticed right away that YouTube was buffering. Initially thought that maybe Verizon was throttling me. My speed was from 0.5 to 3 Mbps max. Restarted phone and did speed test; speed went back up to 10 Mbps. That made me happy again.
Sent from my SCH-I535
Do you guys think Verizon will implement an ota update with a new radio, but also something to lock the bootloader back up?
Well we have some people who have posted the radio updates on the forums here, and I don't think they touch the bootloader (not 100% though), so assuming Verizon does push an OTA for new radios tied with a re-locked bootloader, it'd only be a matter of time before XDA figures out how to install only the radio update.

I bought 3 SGIII's and noticed right away that mine was not getting as good of 4g as my two daughters. Long story short, after 2 weeks I got an new phone with the updated VRALG. Was better but not great. Verizon Reps stated it was a known problem with som SGIII's.
Now I am running Synergy ROM and 4G is alot less problematic, even better than both my daughters most of the time. If I do have a problem I will cycle Airplane mode and it fixes it. My 2 cents
I feel like there's something wrong with my phone. The signal is week and I'm getting abysmal speeds. Like .2mb per sec downloading something. I'm also in a highly populated area where 4g seems to be strong here
Has it been like that since you got it?

If its really that bad. Its a hassle but it'll work...
Dial *#*#4626#*#* or download the "Phone Info" app shortcut, and it'll take you to the same area.
There you can select your radios, Dont mess with anything besides the drop down box with the preferred networks. Set to LTE Only, (defualt is LTE/CDMA/Evdo) when you are in LTE only mode, you should get pretty blazing fast internet. But your SMS/calling outbound and inbound wont work while this is activated.
As for an actual fix... You just need expirament with the different radios... On my Old bionic phone, i remember it was getting really spotty 4g, more than usual. A clean wipe seemed to alleviate the issue. I can't explain why it would it just did...

4G not working

So i recently moved and my phone only gets 2 bars of 3g at home. Even when i move into a 4g area, i get no internet connection. Even getting a 3g connection is rare. Is there a way i can fix this?

Make sure you're on the latest fp5 update. Also make sure you have LTE turned on in the wireless menu (as opposed to just CDMA).
If you've done that and there's no difference, try a reboot. If still no difference, you may want to ask Verizon for a replacement. Personally, however, I would demand it

If you mean how did they react to my complaints? Check the thread.
I got my second replacement phone in the mail today, hopefully it can pick up a 4G signal (or even a solid 3G signal would be nice unlike my current phone).
Interesting enough, I've had the opportunity to deal with 5 Charges thus far (not all mine, mind you). To date, none of them had a problem with picking up a decent 4G signal.
I'm still on my first charge. Have never had an issue that wasn't easily explained, while on GB. Froyo was a bit more erratic though.
