Ok, just a disclaimer (I am well-aware of my n00b status here)... I spent quite a few hours already on this site and on the Android forums, and on Google searching for answers to this... Not to mention time at the AT&T store and chatting w/some other phone reps (including Samsung tech support and AT&T tech support)... And while I've made some progress, I still can't get any definitive answers here.
So... that being said, first (and big 'sigh' I'm sure to many) is that I'm using a South Korea Note - the SHV-E160S. I know this is the I717 forums, but before I get flamed and booted, let me explain...
Well, I am on AT&T. No problems with calls or texting (minus the annoying 80-character limit, but anyways)... However, I have a BIG problem with the LTE. I'm on the LTE data plan, however, I cannot access any data network other than GPRS. Yes, my pings take about 533ms. My download speeds are about 53kb/s. This sucks, quite a lot. Esp when compared to my fiance's Note, which side-by-side gets about 13mb/s on the LTE network.
So... Did some research, and got the run-around... Less all the crap I heard from AT&T reps... It seems that the antenna for my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100. My sources for this come from PDAdb.net (I'd hyperlink, but my post count is not high enough to do that, yet).
So... Here come the questions. First... Is the antenna frequency tuning something built-into the hardware, or is it something that can be tuned via software?
-If it's in the hardware, would it be possible to buy an AT&T-spec LTE antenna? Which antenna gets replaced (from what I understand, there are two, and I can't find a legit source that tells me which is which), and where could I buy such a thing?
-If it's in the software, what would I have to do to re-tune the antenna? My phone is rooted with the latest Gingerbread Tegrak kernel.
Lastly... Though there is a difference between the LTE antennas... I still cannot access any network other than GPRS. I should at least be able to access EDGE, UMTS, HSDPA, HSUPA and HSPA+ as well, but I can't.
If ALL else fails, I guess I could get a portable tethering device with a contract... But that'd be oh-so-annoying to have to carry around all the time, and I'd like to avoid that option as much as possible. I'm paying $30/mo for LTE service on my phone already!
Anyways... Any thoughts or advice would be very appreciated, and my apologies if anything here is out-of-place. Thanks in advance!
U have the international note. Doesn't have late chip in it. But ur note has better CPU then the att note. The international note CPU is not comparable with att lte chipset that's y Samsung use 2different CPU. Yes u should be able to get 3g. Reset your apn. And search around. To find the code to reset your apn. I forgot. Its something like *2260*
I had an international first, had to rest everything to get data. But after few days. I return it cos I prefer to have lte speed more then CPU speed. And I found out the u can just over clock att note to 1.85 instead of stock 1.5. So now I am very happy with my att note.

Hmm I'm not sure if this method works with the International Note but it's worth a try. You need to get into ServiceMode. On your phone dialer keypad type *#2263# and choose 2 WCDMA Band Preference and select (6) WCDMA all.
Reply with your findings.

Thanks for the tip, but all I get is an error: "Connection problem or invalid MMI code."

Maybe the issue is your kernal and/or radio? Isn't the Tegrak kernal Korean? Most likely your radio is also. That is probably your issue. The way I see it you have 3 choices: Live with it, Sell it and buy an I717 variant, Take the risk and at least flash the ATT Gingerbread radio.

he doesn't have the international note(n7000) he has the South Korea Note - the SHV-E160S (he says it in OP), which it has the same processor as ours but some minor diferences in other things.
To the OP, why do you have a korean Note when from your avatar you're in the US?, I'm sure there's your problem, that note is set to use bands in korea and not in US, so the data is going to be crap, and for you to attempt to swap out the antenna is risking braking the phone because you run a chance after swapping it, not working and not having a working phone anymore.

I matched the APN settings of my fiancee's LTE Note first, and that did not work... It's pretty much exactly what you have posted. However, there are a couple things of note (bad pun, sorry). I do not have a 'APN enable/disable' or 'Bearer' field... However, everything else is set the same.

I have a Korean Note because I was living in Korea for a while, and I just got back to the US last week.
As in my OP, I found that the LTE bands are different; however, I can't even get on any other data networks other than GPRS. I've tried some APNs for HSPA+, and the results are the same.
Swapping the antennas shouldn't be THAT big of a deal if I had to... I'm pretty mechanically inclined. Obviously, I need to know if it would provide the intended results or not first.

Hi all. Like my title says I'm thinking of switching to T-Mobile from my ATT Note because I get NO service in my house with ATT and want to switch to prepaid plans. I know T-Mobile has wifi calling capabilities which could solve that issue (albeit start another one cuz t-mo service in the rest of the area isn't that good). 1.) What am I looking at to switch my i717 to t-mo service? and 2.) What do I have to do to get the wifi calling capabilities working? I did see some threads about flashing the t-mo note stock rom getting the wifi calling working. Thanks for any help I can get.
Well ....
It's impossible to tell you that your service will improve by making the switch, as your service issues may follow you regardless of the carrier.
Not all areas get good service ....and if you know others that are getting good service, then I would certainly quiz them about it.
The note can suffer from antenna issues as well, and the switch may not help.
Beyond the obvious, some note users are having sim issues after rooting and switching over to t-mobile via carrier unlock.
This is a random, but serious issue, that causes the device to fail all network connection.
Until a fix is found, users wanting to use the ATT note on t-mobile, are taking a higher than average risk when switching.
If you are looking for more information (highly recommended ) then you will want to visit the " note super everything thread "....located at the top of the general note section.
Please do your homework there, as you "will " want to learn as much as possible.....g
I have a samsung Galaxy s4 that was with u.s cellular, but flashed to verizon prepaid. I am miserable with it. My average data is only 1x. Very rare does my 3G icon pop up. When it does show up the minute I try to search or send something it disappears. I've done the speed test and it's terrible... All show & No go.
It was flashed by Cricket King (ebay) & It seems like I'm just getting the run around. Emails are not answered in promptly, if at all.
Not sure what to do.. was thinking if re flashing to a different carrier like t mobile or metro pcs.
Does anyone know why I would not get 3G on long island new york
zip code 11772
It's frustrating to even get a mms picture messsge out
Help please

Have you tried flashing a different radio?
got the phone yesterday. I really like it. I know it has support for ATT 5G based on some information online (1 out of three bands).
I have tried all the tricks in the book, changed the APN every which way and then contacted ATT to get 5G. They have tried all kinds of things but apparently it's not working.
Anybody else here from the US with 5G success? Curious to hear your story, better even if it's on ATT.
cheers

the answer is no. Maybe there are areas for which this phone might work, definitely not here. ATT support tried all their tricks with the IMEI but they couldn't get past their stupid regulated 5G certification I assume. I am switching - Any suggestions? I know that OnePlus Pro works on T Mobile.
cheers
I had similar problem. I htink that AT&T has done a huge bait and switch, and taken any phones not sold by them, and classified them as 3g phones.
My redmi note prog (1.5 yrs old) just went into this 3g mode, and AT&T support claims they cant do anything for this...
very frustrating.
any lawyers around for a class action suit!??????
I couldnt even get my problem escalated... they said forget about

Wow, I'd definitely report this to the Consumer Court. I just went through an ordeal with Samsung and they were responsive. It's a decent amount of work to go through this. If they truly move these phones to 3G that's a big foul. I would definitely switch. I returned my Xiaomi and switched to a Pixel 5a which works under ATT.
good luck

Setting aside for the moment the ATT tricks (left them in Feb 2020 glad I did)....it depends on what bands are actually being broadcast by the carrier in your area. LTE-wise I remember ATT in my area would only broadcast on bands 2 and 17. 5 was almost non-existent...4 was not at all available. Tmobile on the other hand is big on band 4 in my area, 66 and 41 (due to Sprint) and also on 2. I had a mi max 3 some time back and since it has 4 but no 2 and 17 it did not get LTE on ATT but would have worked fairly well w T-mobile in my area (then I was with ATT)

Can someone help me with understanding this?....or is AT&T making me buy another phone for no reason? I actually left AT&T and went to Cricket wireless because they use the same towers and no other carrier has reception in my rural area. ANYWAY, they made me buy a Samsung A02s because it will work on the network after dropping 3g. The A02s is so slow and junky! I checked the bands that these phones use and the A21s has better specs. WHY CAN'T I USE THE A21S NOW? Can anyone help me with this? Can rooting help me somehow?
Thanks
Depends on the model number.
AT&T has a white list of all compatible phones.
Been using AT&T for 12 years and generally have very little trouble with the network. Reps can be more challenging however I believe you can never get enough assertiveness training. As such I have on occasions been quit the terror for AT&T. Last 3 years though have been calm.
They value long term customers, a plus and reps are given a wide leeway to issue credits. However you need to stay on top of things especially if changing plans. Some reps aren't up to speed.
The model of the A21s is SM-A217F/DS and the model of the slow junky one is SM-A025AZ. I just can't believe the junky SM-A025AZ is more apt to work.

As per the link I provided in my last post it's because it lacks support for band 14. Therefore it's incompatible with AT&T's network. Not sure if this is the cause but if true there's nothing to be done. AT&T supports most popular unlocked models. They will add more models but those will likely be new releases.
This is the stuff that gives me a headache when buying a phone other than through AT&T. Never 100% sure it will work until you slam the sim card it and boot up. With my unlocked N975U1 it went straight online without needing any configuration changes other than the sim card, good as it gets. Before buying a phone always check AT&T's current white list... stay within those parameters.
The good news is the AT&T 4g VoLTE has better bandwidth than ever, no 5G needed. I can stream vids at any time. The implementation of 5G has opened up 4G bandwidth more so it's a win-win for the 4G users.
