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...

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

I warrantied out my first rezound due to the vibrating not working anymore, and my replacement arrived, and its updated to the latest OTA 3.14.605.12, and when i go into mobile network, I only get the choice of LTE/CDMA and CDMA. I remember on my last phone, when i went in there, I had the option of selecting GSM and other options...
I thought the .12 version enabled world options to allow using GSM bands? Maybe I'm confused... I'm trying to get it up and running on a straight talk sim (at&t)

Thanks!
Found that the other day and forgot to post back here. Got straight talk working on edge. Call quality was great, signal great. Wanted faster speeds so i tried the 3G thing and got HSPA working, but signal was absolutely horrible and cut in and out non-stop to where it was not usable 95% of the time. Straight talk is not worth it for me because the edge data speeds are almost unbearable for this phone (maxed at 0.12Mbps if i could get it to even register). HSPA i clocked it up at around 8-9Mbps, but that would work for 10-15 second bursts between switching to 3g and back to edge, and back to 3g, and back to hspa. It was very frustrating, so back on verizon I am. Trying to save money somehow but can't seem to shake verizon for the life of me. Nothing compares to the speeds and consistent signal strength.
Strating a new topic to figure out which radio works better on T-Mobile for AT&T JB update.
Before JB update, like several other people on this forum, I have been using i717 on T-Mobile network . 4G has been working fine with GT-N7005-IMM76D-DXLJ2 Rom and UVLG3modemfori717_gt-n7005amss radio.
1. UVLG3 modem with GT7005 amss gives no signal.
2. UVLG3 modem with JB amss gives no signal.
3. Stock radio and amss in JB update only connects to Edge. (unless you are in area where T-Mobile has 3g on 1900?)
4. Blaze ICS modem connects to 4g but signal bars are not shown in status bar.
For the best modem so far, check the below post...
http://forum.xda-developers.com/showthread.php?p=41052527
If anybody else tried any other combinations, please post your experience in this thread.
Thanks.
same here plus i try it with Telus modems too not signal (signal comes and gone)
I made my own combo for WIND in Canada (confirmed to work on T-Mobile with much higher speeds). It's really slow (about 1 Mbps down and 50 kbps up) but at least it works (good voice/signal strength and somewhat usable data)
It's the SGH-T989D (Telus Galaxy S II X) latest modem (TLMC4) and AMSS from the old Blaze modem posted around this forum. Just flash it with CWM.
http://speedy.sh/uyHBp/SGH-T989D-TLMC4-amss-from-blaze.zip
Steps:
1. Flash in CWM
2. On reboot, do a network scan
3. Open dialer, dial *#2263# and select WCDMA Prefs -> WCDMA 1700
4. Do network scan again, WIND (or whatever your AWS provider is) should appear. Select it and it should register.
5. You can multi task back to the service mode and go back and select "[1] Automatic" to use all bands again.
No responsibility if it bricks your phone, it works on my SGH-i717R without issues
OT: I also tried SGH-T989D_TLMC4_radio.zip and it works on Bell/Telus/Rogers without any mods. However, trying any T989 combos never really worked (some did, but data kept dropping).

This is an important thread for this forum. I'm in the same situation, utilizing the AT&T rom on an AT&T device, and trying to use it on T-Mobile.
My experience has been strange. I am using the stock firmware radio with the AT&T JB update, and I seem to connect to 4G randomly on T-Mobile, switching between UMTS:3 and HSPAP15. I am usually on Edge more often than "4G". I don't have LTE in my area, and "3G" on 1900 doesn't work on my Wife's Iphone.
I tried the UVLG3 Modem for i717, and got no signal at all.
I haven't tried the Blaze modem. What I want to know, is what is the experience with Blaze when you look at system status? UMTS:3? HSPAP?
I am on stock modem in JB rom right now, shows UMTS3 in status.
Nothing strange about that, it is in UMTS when data is idle, anything else is when data is active.
You only get 3G on T-Mobile if its a "re-farmed" 1900 MHz region, where they moved 3G from AWS to 1900 MHz. If you go outside your zone you will only have 2G.

You would have to go to field test mode to find out, Android does not have such details. Dial *#0011# and find at the very top "RRC: .. BandX," where X is a number. Is it 4 (AWS) or 2 (1900Mhz)?
There may be an item (radio dependant) called DC_HSPA to indicate whether its dual cell HSPA(+). Post a screenshot and I can check it for you.

Hmm, can you try this. I've tested it a bit on WIND and data/voice works...the data is slighly more stable/faster (still around 1.5 Mbps/50 Kbps for me)
http://speedy.sh/uyHBp/SGH-T989D-TLMC4-amss-from-blaze.zip
IT works for me on WIND, so it should work on T-Mobile. Same steps as in my previous post above to get it to see AWS carriers. If your T-Mobile service is 1900 MHz, it may just work without any of those steps.
Btw, for some reason it only sees WIND (the modem is non WIND specific) and no other AWS carriers (i.e Mobilicity) when set to WCDMA 1700. No idea why.

Tried it, signal strength went from 2 bars with stock modem to 4 bars, status shows UMTS3 when idle and switches to HSPAP:15 briefly.
Speed test
outside the house 7000kbps/1000kbps
Inside the house 1650kbps/66kbps
*#0011# shows rrc band 4, previously it was band 2.
*#2263# doesn't shows any item with * infront, previously automatic had * infront of it.
Tried setting wcdma to 1700 and saw the same performance, rrc band4 and switching between umts3 and hspap:15.
Havn't tested call quality but this has been the best modem so far.
Thanks for sharing.

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?

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.
Can recommend a radio for this phone? It was originally for Rogers, unlocked, rooted, and I'm using blackstar jelly bean.
At first i used the SGH-T989D TLMC4 radio, only worked well downtown Mississauga.
Right now I'm using the Blaze 4G UVMB1, radio, works a lot better but I live on the edge of coverage so it's spotty at best when I am at home.
So if you have an experience, please give me a recommendation.
This is my exact set up man, good to see someone on this site on the same boat. I've noticed that the T98 works better on 4.2 for some reason. I get really poor reception in my room (switches from mobilicity to CND roaming allot). But on 4.2 I was able to make calls and send text more reliably. Try "kid blaze" though it doesn't show any signal bars but it connects pretty well

Well blackstar jelly bean works really well so I'm hesitant to change. I disabled roaming by making it connect only on the 1700mhz frequency, I don't see it disconnect to much.

I just ported my number to Wind. Reception is a ton better than Mobilicity. So glad to leave them, they were dirt cheap but you get what you pay for. I even get 200$ for addon credits.... kick ass
So my contract is up in two days and I am looking at switching to a Net10 AT&T prepaid SIM service... Any real concerns or issues? I am on latest firmware and radios and running Infection 2.9.1 ROM.
Anybody doing this, comments or wish you had done it differently?
Probably going to pull the trigger in this today unless any red flags go up.
BTW, number porting is not an issue. I'm just going to move my VZW number to Google Voice once everything is working properly.
EDIT: ordered SIM and $50 unlimited card, should be here tomorrow. Hope all goes well...

Sent from my taco using ESPN
The Rezound out of the box supports the 900 MHz and 2100 MHz bands, which are used internationally for 3G and HSPA+. In the US, AT&T uses the 850 MHz and 1900 MHz bands, and T-Mobile uses 1700 MHz and 1900 MHz. The Rezound is great as a global phone, but it's always been limited to EDGE data in the US. This has never changed with firmware and radio updates.
The methods in the thread referenced earlier will let you get the 850 MHz band working with a very non-optimized, weak signal. That means you'll sometimes have 3G or HSPA+ on AT&T. But unless someone figures out how to optimize the signal there, you're probably still going to be stuck with EDGE most of the time.

The Rezound out of the box supports the 900 MHz and 2100 MHz bands, which are used internationally for 3G and HSPA+. In the US, AT&T uses the 850 MHz and 1900 MHz bands, and T-Mobile uses 1700 MHz and 1900 MHz. The Rezound is great as a global phone, but it's always been limited to EDGE data in the US. This has never changed with firmware and radio updates.

I don't think anyone is going to find a way to optimize it for a stable connection for a while. The thread has been very quiet for a while now. Some users did get different results and I read through the thread and some people got better signal using a calibrated sensation nv file.

Hmmm... Unfortunately it appears this isn't going to work as I hoped.
What's working: Voice and SMS out of the box... MMS, Data (2G Edge, speeds in the range of 15k to 50K) with some tweaking in the APN settings.
I tried the tweaks in the other thread and changing the NV settings, it would say it connected at HSPA+ and pull an IP address, but even with the AT&T tower less than a 1/2 mile in direct line of sight from my office window it would never open a web page or work with any app that required a network connection and signal strength was in the nether regions according to Network Signal Info.
Oh well... guess it was worth a shot.

Dang. You sure you didn't miss anything? Edge sucks reaaally bad. I know cause I have T-Mobile. Takes me 2 minutes to send a mms . Lol.

Pretty sure I got everything right. Otherwise I wouldn't have been able to get everything to work on 2g , and I was able to pull an IP address when it said HSPA, I just couldn't stay connected or get any data through. Spent about 2 or 3 hours working on it this afternoon and finally gave up.

That sucks man. Thanks for trying and posting your results though. I've been curious about doing this myself.

I am now in search of an AT&T or other unlocked HSPA-capable Android smartphone, willing to trade my mint condition Rezound for it... Anyone can message me if interested in swapping a similar unit like SGS2 Skyrocket or HTC Vivid... Or perhaps I should just grab a 16GB Nexus 4 from Google?

I've been saving up for the nexus 4 but they might release a new nexus device . If you're eager to get a device , I would get the nexus 4 plus you can do some stuff to enable the lte radio. hecks yeah.
