Mods please sticky this.
There's been several threads with people saying that they are getting intermittent slow or no data connections. Some people suspected throttling.
I did some digging around and found that it is a common issue on all ATT LTE phones. I have read up on various fixes, found one that worked, and will summarize it here.
Create a new APN that is EXACTLY the same as your current one with two exceptions:
1. APN: phone
2. APN type: internet
Save the APN. You should now have 2 APNs. Make sure that the original AT&T PTA APN is the selected one with the green dot.
What we've done here is replace the APN just for internet, and left everything else the same. If you try setting the type of the new APN for everything, it breaks MMS.
There are several dead spots in my town where I get incredibly slow or no data , despite my wife's iPhone working just fine. I made this change and now it works perfectly. Same top speeds for upload and download.
The only thing I cannot test is LTE, since I am not in an LTE area. From what I've read, this is an LTW APN so it should work.
Thanks. Works great and I'm in LTE area.
Very interesting.. thanks for the post.
Just for clarity, we're not to remove "internet" from the original PTA, right?
Edit: Oh, and we can name it whatever we want, I'm assuming? Or does it have to match the original to replace it?

You can't remove the original APN - it's not editable. Leave it as is.
You can name the new APN whatever you want, as long as the APN is called phone.
I am so excited to test this out. I just entered those settings and will report back at the end of the day with my results.
I'm in an LTE area as well and have been experiencing an issue where every time my phone goes to sleep google talk looses connection and I no longer get any push notifications for gmail or my exchange email.

Will see if this helps at all. Suddenly I am having a tong of issues with data on the Note. My skyrocket had no issues in this area. The Note just started experiencing issues yesterday. called att and they reset the data connection on their end and it worked for a few hours.
The oddest part is that the indicator shows I am connected
In an lte area btw.
Oh...another oddity...when calling in to att the guy said his system showed my phone was connected to wifi....my wifi was not even on

Nevermind previous post....
Please note, PTA APN is required if you want to use LTE. Phone APN is for HSPA+. If you are in the area where there is no LTE service, this might be the solution for you as AT&T has a network issue ever since it launched LTE that LTE phones with PTA APN can't get consistent internet access when there is no LTE signal.
So, don't DO this if you are in a LTE area. Or else, you will be forced into HSPA+ network instead of LTE network you paid for.
If you select the phone apn yes....you will be forced into hspa. ..actually in my case it went to no cell connection at all.
There is a theory that simply having it there but not selecting it may help...which doesnt make sense but I am testing it regardless

that's basically what this is - having it there but not selecting it. its almost as if it uses it as a fallback when the PTA apn can't get connected in an hspa area. this would explain why my hspa issue is fixed and others can still connect to lte just fine.
This problem is quite wide spread when Skyrocket was first released. Can't believe AT&T still haven't sort this out.

then you did it wrong. make sure the original PTA apn is the selected one, not the new one. also make sure the new apn type is only internet. I had the same issue when I made those mistakes when I was first testing.
Did this and does not work as people have stated. Doing speed test before adding the apn I would get lte speeds. After adding the phone apn my speed test decreased considerably. This was with att pta selected as well.
ATT has to fix the connectivity issues. For myself, when I do speedtest on lte, it is very sporadic! It times out sometimes while doing speedtest. It's very annoying!

it works for those of us in hspa areas. i guess it isn't going to work for lte areas.
I did the fix and still got 17MBPS on speedtest. I got my mms working btw.
Hrm...i think peopke are doing it wrong. In an lte area, Added it per the directions and the connection issues are slighty better...not completely gone.
No difference in speeds. Lte is the same..hspa+ is the same

UPDATE: This worked well for a short time but now reverts back to the up sell page. My only guess is T-Mo caught on and shut us out; YMMV.
I searched the forum and didn't see this, although I may have missed it. Just wanted to share in case it hasn't been posted or for anyone that may not know.
[Disclaimer: I have no idea if this will inevitably result in a loss of service, so don't blame me if that happens! Proceed at your own risk.]
I recently got a T-Mo prepaid SIM to use with my unlocked i777, as AT&T's coverage where I work is basically nonexistent. I had a rep set me up with the $15/month unlimited text plan which I quickly realized has no web access included (not even pay per MB lol). This was confirmed by opening the browser and being greeted by a T-Mo upsell page.
Okay, so... after some digging around and trying different APN settings, I found a workaround:
APN: wap.voicestream.com
Username: TMobile.com 0000000000 (use your phone # in place of 0000000000)
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MCC: 310
MNC: 260
APN type: Internet+MMS
After saving and selecting the new APN, I now have data! Confirmed this by loading multiple pages in the browser. It may be slow, but it's still nice to have available for the times when you really need it!
Cool trick, did you do any speed tests?
it would be edge (2g) speeds because this phones 3g and 4g (hspa) radios are built for att frequencies only, but att and T-Mobile share the same 2g frequency.
Still working internet is working internet. Good find.

No, I didn't even think about that at the time. As stated above, it'll only be Edge speeds. I'm not sure it would be any faster even if our phone supported the proper bands, since it's using the WAP APN meant for cheapo feature phones.
If data could be fix to use 3g I would go pick up a Sim and only use T-Mobile. Att keeps getting more and more expensive.

This might sound silly, but if anyone knows... 1.) Does there need to be a working Tmo card in the phone w/ that APN (vs. att card), 2.) Does it need to have recurring services or could any purchased prepaid Tmo card be swapped into the 777 in an emergency?
I ask b/c AT$T data services blow in my area and I currently have a network data block to avoid paying for said unusable services...I'm curious if this would work in an emergency on the road or if it's likely that Tmo data is as bad as AT$T's.

An (educated) guess tells me 1. Yes, you would need to have the T-Mo SIM in when using the APN. And 2. I would imagine so, since your phone number is used as the Username in the APN, and I'm sure their network identifies the request as either coming from an active/inactive account.

It's not only with AT&T. AT&T and T-mobile use different bands for 3g. Obviously TIM uses the same bands as AT&T.
Is this still working for anybody? All of a sudden I started getting the web2go error page.
And since upgrading to CM9, I don't even get that anymore. I get Unable to connect to the Internet. No edge logo up top or anything.

My Titan 2 just arrived yesterday and I unlocked it for use on Telus. Bell and Telus share the same coverage areas so me being downtown Toronto I'm pretty much set for constant LTE service.
I'm wondering though how can I tell when I'm on LTE. So far it's only shown "4G" displayed on the screen. I'm not sure if it's actually supposed to say "LTE" or not. I had to swap to a specific sim card to allow LTE speeds which I did as well.
I downloaded the app "BandWidth" to test speeds and I got almost 4.32mb/sec on the Telus network then 9.19mb/sec on wi-fi at home. Can anyone confirm these are definitely LTE speeds and not HSPA speeds?
Just want to know it's working as it should be..
Yes it should say LTE instead of just 4G.
Hmm.. Well then I'm shocked to see that I'm apparently not getting LTE in the only place where you would expect to see LTE.
Can you confirm by chance what type of speeds you're personally seeing on LTE?
As well is there any setting I should be checking to force LTE or make sure it's enabled?

Does you titan support the telus LTE frequency? .... Maybe Telus has an IMEI check for their LTE which blocks unrecognized phones (maybe)
Well I'm not sure exactly what I did but whatever it it fixed it. I did a hard reset yesterday which didn't immediately fix it. I played with the APN for a while trying different things. I changed sp.telus.com to isp.telus.com and this morning I noticed that magically it's now showing LTE.
However my newest concern is that HTC Connection app fails. On my old Titan it works fine and recognises my carrier. And now group texting and MMS fail on the Titan 2 whereas they worked perfectly on my Titan. Doesn't make sense..

Hey everyone! So I've had this phone for about a month now and I'm pretty happy with it so far. Since I've gotten the phone, I haven't seen LTE pop up once (apparently CT has no LTE yet...) but this weekend I was visiting some friends in Manhattan. I know some parts of Manhattan have LTE. for example my friend has an iPhone (same carrier obviously) and he had LTE while I did not.. I made sure my network setting was on cdma/gsm/lte auto and I even went as far as typing in *#*#4636#*#* to check the radio settings. I did get the LTE symbol for like 10 secs but after that it disappeared and I lost service.. Another note to make is that I'm not on the stock apn setting because I changed it to epc.tmobile.com to boost my hspa+ speeds.
That's why. Lte uses fast.T-Mobile.com apn from what I'm aware of.

As the above posters mentioned make sure you have the fast.t-mobile.com apn.
BUT be sure you spell it right. LOL i made the mistake of spelling fast with fats and it took me 2 days to catch my typo. It would show the signal strength of LTE but not actually connect to it.

Haha that's so funny! One more question even though I wasn't on fast.t-mobile.com and was on epc.t-mobile.com i still wasn't able to see the LTE icon, any clue why? Thanks!
The only thing i can think of is that HTC / Samsung seem to have lower DB reporting of the actual signal strength compared to Apple.
Ive been in a discussion on other threads about how the signal indicator on my Note 2 and HTC One always seem to show low signal when LTE is connected.
Another person chimed in stating that they compared their HTC One to an iPhone 5 and noticed the signal indicator on the One shows 1-2 bars and the iPhone 5 showed full bars LTE.. Same T-Mobile Network phones side by side.
My rebuttal was simple. I downloaded an app that showed on both my Note 2 and HTC One a higher decibel reading then what my phone software was showing.
What leads me to believe this is with 1 bar i can still get 20+ megs down and 15+ megs up. Normally in low signal speeds would degrade.
I was also with Sprint on the GS3 and EVO LTE and the EVO LTE suffered from the same problems early on. They sent out several firmware and radio updates that corrected false and low signal readings and right before i left Sprint my EVO LTE outperformed the GS3 When / IF i could find LTE in Dallas on Sprint.
Give it some time. Im hoping they put more towers online and that devices get radio and firmware updates to perform better with the LTE that TMO is using.
I don't think the APN matters. I use the different APN for faster HSPA and I can still get LTE. I'll show you when I get home or in an area with LTE. LoL!! Also, in that very thread it was stated that changing the APN won't affect your LTE.
perhaps BUT if you misspell the apn then it wont be effective at all.
APN:fats.t-mobile.com you wont get an actual connection to LTE because its supposed to be fast. not fats.
This also happens if its the ONLY apn. If you have multiple APN it will revert back to another that works..
but this only happened to me so who knows..

It could be the radio firmware. HTC continues to update the radio with most releases fixing bugs..you should report this bug to HTC dev. Because I have the same issue NEVER get above 1 or 2 bars on LTE T mo

Anyone here running CyanogenMod by any chance?
I just got the HTC One and flashed away Sense the very first day. Despite living in Chicago, the phone's signal has been pretty shotty and even dropped to 0 in areas where T mobile claims to have "4 bars". My girlfriend complains about hearing static in the background despite the signal being clear on my end. After speaking with T mobile customer service today, I was told it could be the phone or the whole rooting thing...not sure whats going on and I only have three more days to return/replace the phone. Anyone here experienced anything like this?

When it comes to service recognition by the radio and software of the phone, the apn doesn't matter. Think about the apn settings as joining a proxy server; if you notice you are just placing IP, web server addresses and port information in that settings page, and you must be already member of the network (have connection) for these settings to be relevant.
That is why if the apn settings are wrong you will still have service but not receive data.
The issue with one phone displaying LTE right next to another which is not (same provider) comes about how the software for the radio is configured and how well calibrated is the antenna of the phone and the radio processor... And a few other environmental factors too.

First time posting on here so please don't tear me a new ass if I'm doing something wrong lol.
I just got a Galaxy Note I (SGH-I717) on AT&T.
Initially I was having problems with reception and 4G and not getting LTE at all. I finally got LTE working my setting up the PTA APN and by dialing *#2263# and selecting a different preferred band (I chose "LTE ALL" in the LTE sub-menu and saved it). I put the SIM back in, powered the phone back up and LTE was working. However my signal bars haven't gone past one bar while on LTE. I get data, and can even send and receive MMS/SMS, but cannot send/receive calls.
Someone please tell me if I did something wrong or am leaving out any vital info.

Perhaps the radio should be updated. The latest official ATT radio is UCMD3.
Check if you have it under settings/about/phone status/baseband. It works on all builds but is the newest radio which improves signal sometimes.

I'm pretty positive that my APN settings are correct (I'll post them in a minute), I think it is probably the band preference I selected in the *#2263# menu. I do know for a fact that the SGH-I717 runs on the lowest LTE band.

Those appear to be as follows in the link I posted. The only difference i saw was BEARER: LTE (default is unspecified) play with this one.. that was different in the post.
Other then that, I know ATT and Tmobile only use LTE Band 4 in the USA anyways.
So LTE ALL under the service menu wouldnt help. Was your coverage always that bad?
Please someone with ATT help this poor soul out. I'm at wits end. Usually this would be something to bug your service provider about. Myabe they can refresh something on your account, or give you a newer SIM card at your local store.

Yes, unfortunately service has always been this bad. I have called AT&T several times/been to the AT&T store and talked to a representative and they have done the following:
- Checked/rechecked my IMEI number (it always matches)
- Checked and rechecked my SIM number (before AND after I received a new SIM card
- Unregistered/Re-registered my phone with the towers
- Called a tech out to the tower to make sure nothing is going on the them (I know its not, my buddies all have LTE running fine on their devices)
Thank you so much, scariola. You've been a helped all you can.
RESOLVED
I believe I have fixed the problem.
I dialed *#2263# to get to the Band Selection screen. I already had selected "LTE ALL" under the LTE Preference menu. I unselected it, chose Back and then End (both under the softkey menu). I then re-dialed *#2263# to get back into the Band Selection menu except this time I selected "Automatic" and chose End in the softkey menu. Re-inserted SIM, and rebooted.
No I get signal 3-5 bars, 4G and 4G LTE where strong signal is available.
I thought LTE was only data and could not be used for calls.

Right. The data is the 3g/4g connection and the symbol next to the bars is the data speed. The bars is the strength of the gsm/phone signal.
It actually sounds like the OP was involved in a tower maintenance scenario and probably didn't matter what he did.
You can do the same settings changing from the mobile data settings menu.
You can't do the same settings from the mobile data settings menu. There you can only mess with data bands. You can turn LTE off or on on my Canadian ROM but you can't use it as the only band. And I didn't think you could even change this on ATT ROMs/radios at all. I believe he used LTE as the one and only bands for phone and data which caused his issue. I have achieved this same result by messing with those band setting found by *#2263#.
However the ability to send/receive texts but no calls does not make sense. That could have been tower issues since they both use the same phone band.

You can't do the same settings from the mobile data settings menu. There you can only mess with data bands. You can turn LTE off or on on my Canadian ROM but you can't use it as the only band. And I didn't think you could even change this on ATT ROMs/radios at all.

Er, what?
Is that a JB thing because I know it wasn't present on the ATT ICS ROM. Also where is the LTE setting??
The default is "fastest available". If you choose the high speed setting, it will connect to whatever is best.
I assumed JB stock because the OP said he just got the phone.

It's on the canadian version of JB in the settings/mobile network. Missing from att JB though.
You can however force LTE only through the service menu. Att and tmobile use band 4. Not sure about anyone else.
You must dial *#2263# into dialer and select LTE and choose the band your provider supports. That will force LTE only. Dial the same thing into dialer and select automatic* to go back to jumping through LTE/WCDMA/GSM.
I understand it is on the Canadian version as I am using it. The Canadian version also includes LTE. I know how this all works. I have a Rogers note. But my question was to ranger on where he pulled that screenshot from. I always had an LTE option both on ICS and JB. And it was my understanding that ATT left this feature out on all versions and their modem was locked.

You can't force LTE if its not available. Its best to leave it at auto and let the modem do Its job of connecting to the best signal.

Right. The data is the 3g/4g connection and the symbol next to the bars is the data speed. The bars is the strength of the gsm/phone signal.
It actually sounds like the OP was involved in a tower maintenance scenario and probably didn't matter what he did.
You can do the same settings changing from the mobile data settings menu.

It may have been, but soon after I *thought* I had fixed the problem, the same issue restarted. I believe it was an issue with the phone hardware itself, maybe the antenna. I don't know. I sold the phone and got an S3.
No problems with the S3 :good:
I used to have that problem until i changed the MNC to 260
Hi guys,
I have one more day to return my phone and as much as I love this phone, I'm considering it because my phone is constantly switching to 4G HSPA+ instead of LTE. I'm in the middle of Los Angeles, and this even happens when I'm walking outdoors.
I can easily prevent this by changing the mode to "LTE Only" in the testing settings, and LTE works perfectly with no issues whatsoever. However, in this mode, calls do not work - it simply refuses to allow them.
Does anybody have any ideas? The speeds I get on HSPA+ are unbearable for some reason (see attachment). LTE works fine with about 8-12 mbit down.
I have tried changing the APN settings to be optimized for HSPA+ but it seems that prevents any access to LTE - which is opposite of what I want.
Thank you!!
you might want to give us the APN info so we can look at it and see if its right or wrong.

It's set at the default (and I reset it again to make sure) - fast.t-mobile.com
I've tried using epc.tmobile.com as they say that helps with speed when you are connected to 4G HSPA+, but it also seems to prevent ANY LTE access whatsoever.
