[Q] Strange problem need some help. - AT&T Samsung Galaxy S II SGH-I777

Im having an issue with my i777 on tmobile. The phone is sim unlocked and has the proper apns. Now in chicago i get good edge speeds and every now and then depending on the area(like downtown chicago) Ill get full 3g speeds. Now heres the issue my friend has an i777 that worked on and he has tmobile post paid. I have tmobile prepaid. He gets nearly full bars in my apt yet mine stays @ one bar or no signal. So my question is: Is there something wrong with my phone or is simply my location. Also he does not have any of the roaming options enabled. Thanks for your time.

Maybe it's a difference in modem?

Nope both are on the ucle5 ics modem.

im in houston with my international SGS3...
i have tried 3 modems, and i can seem to get above 1.5mbps downloading EVER, unless on WiFi
what speeds are you guys seeing on average with international note in the US on AT&T

Exynos not compatible with AT&T Network. Only HSPA+ I have the HTC One X Quad core on Straight Talk (AT&T MVNO) and get gravy HSPA+ speeds here in Charlotte
so what your saying is no matter what i will not get any better speeds than 1.5 and lower. i get 3g/4g/h+ on my SGS3 right now. unless there just false indicators in the notification bar so i dont see the incompatibility.
Im still in my "iphone" plan and get about 6mb down

i would take a consistent half of that....lol
i really didnt think it would be this slow. i mean the phone is blazing----but let me try to download an app. or start up netflix on the go, i even see it in web browsing it just seems slow. and my infuse was not LTE and it ran h+ and got the same 5-6 on at&t
I'm averaging around 3.5 down and 1.5 up on at&t in central pa...ps we don't have lte here...yet

There is definitely something going on with the SGS3. Right next to my unbranded SGS2/GT-I9100, I'm getting much lower speeds on the exact same network. I'm talking 7.5Mbps vs 3Mbps on AT&T.
Not sure if the modem's just not optimized for the US AT&T networks (yet).
Thank for the test, i really didnt think this was normal. i hoping to find a modem that works well enough to get me the 3-4 mbps......
right now, all yesterday......i could NEVER even get above 300kbps
i love the phone less this aspect of it right now.

no
to the OP and anyone experiencing slow network speeds, check you apn settings on the phone make sure you have the ATT phone apn selected (apn name phone) instead of the default Cingular apn...Phone is the HSPA+ apn but on unlocked international phones it defaults to the APN provided by your sim which is the Cingular one...case in point on my nexus i have to always manually input the phone APN after flashing a rom...
also even though 2 phones running on the same network maybe in the same physical location, they may not be connected to the same Cell Site Tower, as such each phone maybe communicating with different towers with varying degrees of network congestion, thereby affecting your speeds...it could also just be the area you're in...as another ATT user with an international s3 has posted screens of him gettin 8mb down

I'm don't think you can switch to the phone APN on the $10/$15 medianet plan... has this changed?
I understand cell towers, but you have to realize you're really reaching with that explanation... especially when I am able to get consistent 6-7.5Mbps ALL DAY on the GT-I9100 when I have not been able to hit 3.5Mbps downloads sitting in my office all morning. I'm talking well over 10 tests at various times throughout the day, SOMETHING is up.
CONFIRMED: phone APN does NOT work on the medianet plan, so let's not muddy the water and confuse the issue at hand.

Well if you can't change the APN..you can either complain to ATT or try another S3...for me when I first got my GNex I got crap slow speeds on HSPA+ till changing the APN...but I am not on a medianet plan..

That's the point, I'm talking about the medianet plan, and getting much faster speeds on a phone sitting right next to it. Repeatable results too.
Again, has nothing to do with APN in this case.
Cmd512, are you saying that the s3 will not work with medianet data plan?

NO, that's not what I'm saying. I'm saying I'm seeing significantly slower speeds than my UK GT-I9100 when running the same exact speed tests at various times during the day. Could just be a modem issue as these phones were launched for the UK region, who knows.
Okay thanks, looking to purchase a galaxy s3 and justifying the savings from the 5gb data vs medianet plan to my wife. BTW what color is yours?

HSPA issues

I have a International Galaxy S3 I9300 bought in India and i have come to US and have took a TMobile connection. Now the issue is that , im not getting 3g(h,h+) speeds all the time. I have set my device in Auto(GSM/WCDMA) . I have another guy under same roof using same Tmobile conn (Nexus 4) and he is getting 3g speeds and im not. Its showing as Edge('E') in my phone. I can confirm that the 3G is working at some places near my apartment so its not an activation issue or something. Does it has to do anything with the ROM/kerner . I have been using the Foxhound/Persus combo. Should i change the modem settings?
Try setting the Network Mode setting to WCDMA only (instead of auto). I am on AT&T, but was having same problem in certain areas and this fixed it.

Yes, i tried this, but the network goes blank. I'm sure im covered under a 3G area as the other guy is getting awesome speeds under the same roof. Was it because the other guy got his mobile in US(Nexus 4) and i got the international version that it could not read certain spectrum? Really confused.
Did you compare APN settings with other phone? Somewhere here there are probably APN settings that are optimized for T-Mobile. Or may find them on Google.
My gt-i9300 does the same

I'm on omega v35 and I have tmobile as well. it seems I get this edge all around were I live but then I'll go about a mile in any direction and I'll "all hspap??, 4g, 3g., all" I guess thats because of the towers mabey and the fact that I have the international as well. If any one knows why I would like to know as well.

HSPA+ on Solavei?

I attempted to do my homework on device compatibility beforehand so as to avoid the shock of something like being stuck on EDGE for data. Nevertheless even with a video review showing the DNA operating HSPA+ on Solavei I am stuck on dreaded EDGE. The activation period took a couple of hours with my new phone (DNA) being able to dial out but SMS/MMS non functional as well as calls to my handset. EDGE was running during this time but after a bit I saw it flash to 3G then H.....success! NOPE. At this point I verified SMS and all calls were working and my phone seemed to want to connect to HSPA+ but was having network communication issues when trying to run speed tests. I attributed all this to my home location, it having always with any carrier been quite on the outskirts of general coverage even though I'm only 1/4 mile from town which is a bit ludicrous in itself. Later that night I drove a little into town to test the data and alas H+ lit up, ran a speed test 2.5MB download...not to shabby IMO. Next day I drive to work and into the center of my home area where the best coverage is for ANY carrier and the entire trip H+ only lit up for a few seconds. Ever since there is no change in data always on E. I called Solavei and told them the issue and they pretty much gave me the runaround and couldn't definitively explain why it worked for a short period but wouldn't now. I can't 100% confirm that T-Mobile has refarmed the area to 1900Mhz but I read my city in a list of 49 in an article that said they were done. This being said I'm forced to let this month play out until possibly switching carrier perhaps one that uses AT&T instead. I asked Straight Talk about my device and they said they offer SIMs for both AT&T and T-Mobile but AT&T is limited to 3G service only whilst T-Mobile should work for HSPA+. I don't know if this a T-Mobile issue or a Solavei one or it's just my phone, but don't see how it could be the phone since it was up and running briefly.
I use T-Mobile and my connection is all over the place at times, refarming is actually the reason I think, its going for the strongest signal, if its edge, it gets edge towers, until the refarm is done I think we'll continue to see this kind of behavior for awhile. As time has gone by its gotten better around here with less time on edge and more on 3g/h+ since I first got the phone.
I can't vouch for at&t but no h+ sounds a little strange to me, if anything bands wise they should be more compatible then T-Mobile.

It sounds like the refarm is much more of a gradual process than a one and done. At least I hope so or else there's not much to look forward to there. I know the Solavei rep was full of complete and utter BS since she told my phone was incompatible since it wasn't on their database of phones to service APN settings OTA. I may try out Straight Talk or Net10 just to see how the AT&T network speed performs.
Sorry for my ignorance, does the DNA really get H+ (42Mbs) ? On GSM network?
Thanks

No reason it can't, hardware supports it if you have the connection to do it. In my coverage I'm usually edge or 3g so I can't say for sure.

I ended up leaving solavei (T-Mobile) for net10 (at&t) The coverage is worlds apart in terms of hspa. I get it everywhere though the speeds fluctuate but are decent. T-Mobile definitely needs to expand coverage it was not good where I lived about 80% was edge.

[Q] i717 on T-Mobile LTE goes to EDGE instead of 4G

After almost a year of inputting various *# and #* codes, I finally got my i717 to work on T-Mobile LTE (southside of greater Chicagoland).
This is on stock ATT JB rom and modem. On a good day I will get over 20Mbps down and 8-10Mbps up. epc.tmobile apn worked best at first, but after about a day or so, fast.tmobile apn setting did about the same. Service mode is set to Automatic and the setting in Device Info *#*#4636#*#* was set to LTE/GSM/WCDMA.
I thought all was fine until I would leave an LTE area and go into a normally (for me) 4g area
What is happening now is that I lose my LTE and go straight into EDGE. It is almost like my regular 4g is gone in areas where it used to be pretty good
Before LTE working, I was getting pretty good 4g (between 4-9Mbps down and about 1 up). This was using the same stock ATT JB rom, but with T-Mobile Blaze modem. Very seldom, like almost never, would I see EDGE. To get this I would have to go into service mode *#2263# and select WCDMA as my band preference.
If I try to use the Blaze modem, I cannot get the phone to stay in the LTE/GSM/WCDMA setting.
In a nutshell, why am I going to EDGE instead of 4g when I leave LTE?
If it matters, I am on the 5G / 100 minute $30 prepaid plan
TIA
Pretty common problem with the JB modem. You pull LTE or you pull E. For me, the best modem is UCMB4. It's an ICS modem, though, so I'm not sure how it'll work on jellybean. But you may give it a try. I pull the best speeds -- by far -- with it, and I pull consistent LTE. With the different ported modems I would have calls not go through sometimes -- weird -- and just "okay" speeds. With the ucmb4 I get solid all-around service.
I've gone from TMobile LTE to regular 4g on my mostly stock Note in Chicago. No AWS mod, no code messin, no nothin.
ATT modems will only work with tmobile refarmed 1900mhz areas. Your blaze modem is set to 1700mhz frequency band instead of 1900mhz. Thats why it works better.
Tmobile has a lot of dead areas on regular 4g with the LTE capable modem. But that's the tradeoff. Lte and refarmed 1900mhz band or just regular old 4g hspa.
no phone on Tmo 4g LTE in STL
Hey guys,
I've recently run into a problem with my unlocked i717 on TMO. It runs Android 4.1.2 (AT&T update flashed to the phone) but every since TMO rolled out their LTE in my area I get 4G LTE signals (1 or 2 bars mostly, but at times 3-4 bars) and I can send texts and data, but it cancels both incoming and outgoing phone calls.? What can I do to correct this? TMO's solution is to buy the N2 or wait til Nov for the N3. Any ideas?
Thanks...
Pete

Make sure your using the UCMD3 modem for JB. Then type *#2263# into dialer and try to set to automatic*.
Someone had this similiar problem the other day.

Thanks for all the comments. Glad to hear it is common problem and not just me going nuts.
I still like my i717, but seem to spend more and more time screwing around with it to get it to work right. Good excuse to get a Note 3 I guess

New T-mo customer, slow data speed!

Ok, so Im a new T-mo convert and I picked the S5 and prepaid unlimited everything ($80) plan. Im in the San Juan area in PR.
Ive been getting horrible data speeds <1Mbps since day one on the phone. The curious thing is that from 2 am to 6 am for (6 days straight now) speeds jumps to 15Mbps or higher. As soon as 6am ticks I'm back to Edge speeds. What is even weirder is that I swapped the sim card to my Note and started hitting 17Mbps or higher at any time.
I tried the new modem and it didnt work either. I also tried changing APNs to different values and going wcdma mode only and none work. I contacted customer support a few days agoand they said they would fix it but they havent. Since I'm on the 14 day thing, I think I may just return it.
Anyone with similar experience or know what could be going on?

Are you using the SIM that came with your new phone?
Sent from my SM-G900T using XDA Free mobile app
I am. With that sim on the S5 I get no data or edge speeds when I do get data,except from 2 am to 6 am which I get LTE speeds.
With that same simcard I get LTE speeds on my Note at all times.

Return it and ask for a new one, I live in Caguas but I work on San Juan, and besides when I'm at the office, where all providers have the same signal issue, I have normal Data Speeds.
I must say that when I'm at home in Caguas, I get great LTE Speeds but in San Juan I have noticed that using 4G instead of LTE gives better download speeds, but from that to the issue you are describing is a great difference, that's why I'd suggest you get a new one during the 14 days.
