[HOW-TO] Get 4G Speeds on AT&T

So it seems like a lot of people are having trouble getting 4G speeds with AT&T. After a couple days of back and forth with sales reps and tech support, I think I have it figured out. I'll try to make this an easy to follow guide.
Getting the Right Data Plan
First thing's first, you need to have a 4G data plan. To check which data plan you currently have, you can log into your account on http://www.att.com. After logging in, mouse-over the "Wireless" tab at the top and click "Add or Change Services." From here, you can scroll down and view the "Web, Text & More" section. This is what mine looks like.
Your data plan has to be a 4G Smartphone plan. If you are coming from a previous 4G phone, and you just popped in your old sim card WITHOUT calling AT&T, you should be all set and you can skip to the next section. However, if you DID call AT&T to give them your Nexus 4's IMEI, your data plan will default to "3G for Blackberry" or something similar. This is because the Nexus 4's IMEI isn't appropriated as a 4G smartphone in AT&T's system.
You have a couple options at this point. You can try to contact AT&T, explain it to them, and hope they give you a correctly provisioned data plan. This can be a quick and simple fix, and has worked for some people. However, it didn't work for me. After speaking with customer service over live chat, tech support over the phone, and going into both an authorized retailer and a corporate store, I was told that they can only provide 4G plans to AT&T branded 4G phones.
The solution to this is to give AT&T the IMEI number from one of their 4G phones. (NOTE: The only thing the IMEI does is tell them what type of phone it is, and what plans can be assigned to it. IT IS NOT LIKE A SERIAL NUMBER, AND AT&T WILL NOT CHECK TO MAKE SURE IT IS UNIQUE.) Find a friend with an AT&T 4G phone and note the IMEI number. You can quickly pull it up by typing *#06#. Then you can call AT&T customer service, tell them you have a new smartphone that you would like to get the correct data plan for, and give them the IMEI number you just copied down. (I told them I have an LG Optimus G, which isn't too far off I suppose )
Now you should have a 4G data plan.
Setting the APN
After you confirm that you have a 4G data plan, you have to set the correct APN. To get into the APN settings, go into your android settings, under "Wireless & Networks" go into More>Mobile Networks>Access Point Names. You can either select the menu button and create a New APN, or you can select the one already there and edit it to match the one below.
Code:
APN Settings:
Name: AT&T HSPA+
APN: pta [COLOR="Red"](NOTE: IF YOU DON'T HAVE AN LTE PLAN, CHANGE THIS TO "PHONE")[/COLOR]
Proxy: Not set
Port: Not set
Username: Not set
Password: Not set
MMSC: http://mmsc.mobile.att.net
MMS Proxy: proxy.mobile.att.net
MMS port: 80 [COLOR="Red"](NOTE: IF MMS ISN'T WORKING, CHANGE THIS TO "8080")[/COLOR]
MCC: 310
MNC 410
Authentication type: Not set
APN type: default,admin,fota,mms,supl,hipri
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Bearer: Unspecified
Be sure to hit the menu button and save the APN, then select it in APN settings. If at this point you fail to get a connection, you most likely don't have a 4G data plan and should go through the steps in the first section.
Enabling LTE
This part is optional, but I see no harm in doing it. Type *#*#4636#*#* into your phone. This should open up a "Testing" settings screen. Go into Phone Information, scroll down to "Set preferred network type:" and select "LTE/GSM/CDMA auto (PRL)" from the drop-down menu. If you happen to be in an area with AT&T band 4 LTE, you will be able to connect to it. According to this thread, AT&T has band 4 LTE in the Oklahoma City area. If anyone else can confirm any other areas, maybe we can get an idea of how widespread it is.
Hopefully this has helped some people. Let me know if there are any inaccuracies or changes that should be made.

Does it have to be 4G LTE? Mine just says the same thing, but 4G. They set it up in the store, as well, but they set it up as my old SGS2, which has 4G, but not LTE.

I have galaxy s3 with LTE data plan so so when I get my nexus , I just need to set up apn . Thats it right.

No, it doesn't have to be LTE. You should still be able to connect to the HSPA+ network. You only need the LTE plan if you want to try to connect to the band 4 LTE network in the few areas AT&T has it.

So what are the speeds with this?

I do want the LTE network, so I guess I should call and get that changed. However, nothing works at all, no data, no HSPA, nothing. I guess 4G plan isn't valid.

NO LTE in St. Louis

Right, all you would have to do is put the sim card from your GS3 into your Nexus 4. It should set the APN automatically since it's already a 4G plan, but you can always double check.

This would depend a lot on your area. I seem to be getting 8-10 Mbps in a HSPA+15 coverage area.

grandfathered
Dose anyone know if this will negatively affect a data plan that is grandfathered unlimited. I don't want them to mess that up.

Try changing the APN setting from "pta" to "phone". I believe pta is the setting for the LTE plan, and phone is the setting for the regular 4G.

I think you only stay grandfathered unlimited if you don't change your plan at all. I have the 2GB plan that is no longer available, and on the "Add or Change Services" page it tells me that if I make any changes I won't be able to revert to my current 2GB plan. I would assume it's the same for all discontinued plans.

i have grandfathered unlimited data from an old iphone 3gs plan...here is what it says on att's website:
Data Unlimited SmartPhone Personal
Data Plan for SmartPhones. Unlimited domestic data usage. Only available for upgrades. Requires customers to be on a "Gold List" Data Unlimited SmartPhone Plan prior to upgrade to 4G device.
so is this considered "4G"? i live outside of philly and the fastest i've ever gotten on speedtest was around 6 mbits/sec...99.9% of the time it's between 1 and 3 (this is on my galaxy s 2).

As far as I know, they label all the 4G plans as such. What are your APN settings? If it's wap.cingular, I'm pretty sure that's 3G.

Mostly correct -- I was under the belief the wap.cingular isn't able to achieve HSPA+ speeds (I was only able to get 1mbit up and down). Someone else in a different thread told me that they were connecting at HSPA+ speeds on wap.cingular. So it turns out APN's alone aren't directly indicative of what plan you have. However, being able to connect on either "phone" or "pta" APNs is pretty much a guarantee your plan is provisioned correctly as those are the APN's used for HSPA+ as well as LTE.
Here's my exact post from the other thread : http://forum.xda-developers.com/showpost.php?p=34778373&postcount=19

It may well be true that AT&T don't check that an IMEI is unique, but actually it IS a unique serial number ....

So far only updated the APN, and I was on the wap.cingular, with a grandfathered data plan. My Speedtest results after the APN change is now DOUBLE my wifi connection speed via DSL. I'm outside city limits South of Holland, MI, and getting 7-9Mbps now. I can't wait to go up to Grand Rapids where I know ATT has a very robust 4G network and see what I get there.

So would LTE on AT&T work with the non-smartphone unlimited data plan?
Does AT&T even pick up the nexus 4 as a "smartphone"?
Thanks

It appears some people who are in AT&T LTE coverage where AT&T does not have 700MHz licenses are getting LTE over the AWS frequencies (the same ones used in Canada). The Nexus 4 only appears to have LTE operable on AWS. There's more about it in this thread : http://forum.xda-developers.com/showthread.php?t=2021173
It's unlikely LTE would work with the non-smartphone data plan as those require the "pta" APN, which is only accessible on LTE plans.

Atlanta here.
I double checked to make sure I had my settings right, according to the OP.
I'm not getting the LTE symbol in the status bar (only H) and getting 8-10 MBPS down according to the speed test.
I assume that's still HSPA+ for the Atlanta downtown area. (By GA tech)

AT&T iPhone 4S SD Chip to N4 - 4G Compatible?
I am switching over from an iPhone 4S to the N4 and cannot get 4G data speeds (actually the best I can get is sub 2mb/sec). My old APN was wap.cingular and I beleive I was only getting 3G data with the iPhone; however, at some point AT&T started calling my service 4G and that is what would show up on the phone. Can anyone confirm that the iPhone 4S to N4 switch will require me to take the IMEI route to get the AT&T 4G speeds. Thanks for the help.

HTC One 64GB Developer Edition signal strength

I just received a Developer Edition 64GB HTC One. I also have in my possession the AT&T Store model. I was receiving 2 to 3 bars signal strength at home with the AT&T version, but when I started using the Developer model, I was receiving one bar.
Also noticed with the developer edition, I was moving between HSPA+ and LTE frequently and even lost signal when I went inside a store. Is there anything I can do to fix this? Is anyone having the same problem?
I don't want to return the Developer edition but signal strength is important to me and I may have to, if it comes down to it.

Bump

I am by no means the most knowledgeable person here but I was for many years an employee of at&t and in that role was part of group of people that tested pre-release devices as well as upgrades to those devices post release...
So with that I know that at&t is known to manipulate signal meters on the OS of devices as part of their "network optimization". So what that would mean is that the signal strength measurement of a device with non-at&t OS might show that -95dBm is one bar, the same device with the at&t branded OS would show two or three bars. Leading the consumer to think that they have better coverage than they do.
I am not suggesting this is for certain the case but you can probably find a reliable signal strength tool for free in the play store and load it on both and compare the actual dBm measurement and you may find that they are close to the same and that the signal meter is not as accurate.

Edit: I downloaded Network Signal Info by Kaibits Software and it seems to have a lot of useful info.

Ive never worked for AT&T but this is very true. As someone who always has the latest phones (me) its very apparent when you go to CM or any other non carrier ROM that you notice how they manipulate the signal meter.

The real answer here is that there is no difference in reception, only in signal bar representation. I believe the developer edition has a bug because the range represented isn't quite correct, it bottoms out at -113 dBm while 10 MHz LTE like on ATT should bottom out at -125 dBm.

Same situation but signal is in fact lower.
I actually found this posting searching for this exact problem. I have the ATT and the Developer edition. I noticed the bar difference but as everyone has been alluding to, I just wrote it off as how signal displayed as being wrong. However, when I turned the WiFi off and was trying to use the mobile media only, it was so slow to non existent in LTE but it changed to non LTE and did have some throughput but as you experienced it kept changing around. Again, the ATT version had great throughput and speed and stayed solidly on LTE. I am sorry I do not have the solution as I am also trying to find out what is going on and as you, I do not want to return the unlocked phone. Hope we find the solution soon.

Did ATT have different APN on the One? They have changed APN many time before. I have the dev edition with a LTE sim(one come from an ATT LTE phone), can some one post the APN from a ATT One?

Although the ATT One did have one test with DL speed of @21 mpbs, subsequent tests were @ 5mpbs, which were the same as the Dev One.

FYI: I also ran Network Signal Info app which showed both devices picking up same signal (-85dbm), but each had different number of bars (ATT One had 4, Dev One had 2)

I have the same problem in Massachusetts. I have both phones At&t and dev. The dev can barely keep an LTE signal. The At&t is fine. Any thoughts on how to extract the radio from the At&t model and flash it on the dev model?

hmm, that's what I have. I am in NYC this week and the LTE IS pretty fast. 16mb d/l
Sent from my HTC One using xda app-developers app

No need for an app. Go to Settings > About > Network. Compare the dBm there. I am getting great LTE on my unlocked edition. Got 37 Mbps down, 18 up when I tested yesterday.

-105dBm
8.33 up
6.57 down
inside my house with ATT LTE

I work in a large office building and my previous phones had a very difficult time holding an AT&T signal.
The worse for me was the Nexus 4. Up until yesterday, I was using the Samsung S3 and it did quite a bit better.
The HTC One is doing a FANTASTIC job for me. Much better reception and 2 or 3 dBm better than the S3.
So far, no complaints.

This is making me feel a bit uneasy... I hope I don't have any problems with mine! Glad to know people are aware of it, I guess...

The signal strength is the same on both devices I have (ATT and Dev). The only difference is the way it's presented or each device's interpretation of a "good signal".

Some people were saying they have the AT&T and Developer edition and the Developer one actually dropped connections where the AT&T one held strong and was very fast. That is what scares me.

I want to make sure people are not getting caught up with signal levels in dB. I have personally spent a good amount of time testing both phones. There is several times that the DEv unit was not operating in LTE frequencies and the At&t unit was working perfectly. So I called HTC to complain. I would like everyone else to complain to HTC. They are blowing this off. There needs to be as many complaints to get this escalated. Please do not dispair about complaining to HTC thinking your phone is OK.

I had both phones for a day and, while I didn't compare signal strength (only one sim), I haven't noticed my Developer edition having any issues with signal since I took my AT&T model back.
Speeds are right where they should be and I have had no dropped calls. Maybe it's a placebo effect.
I have to say, though, even if I knew for a fact that the AT&T model consistently got better reception, I would still choose the Developer edition for the lack of bloatware, wireless tether, and factory unlocked bootloader.
We're bound to get a firmware update eventually that includes a new radio. I'm sure it will get better. Assuming that it's worse, I seriously doubt that it's hardware.

Stop spreading your lies, Walternate, or we'll take out a chunk of your brain!

My developer edition is pulling down 43.6 down and 12.8 up inside the house on AT&T LTE. Current signal strength is -81 RSRP and -7 RSRQ.
I had a problem with the Dev edition not working properly with my AT&T SIM card yesterday when the phone arrived. All the phone functions worked fine, but Data did not work at all. It gave me a message that the APN was configured wrong. (Even though it was the stock AT&T settings.)
I stopped at my local AT&T Corp store this afternoon while I was out and they swapped me into a new LTE SIM Card for free. They also checked my IMEI and I believe they added it to my account info. A quick reboot and things were working fine and flying along. Apparently some of the SIM Cards are set up for the HSPA + "4g" network and do not have something authorized for the LTE. Both my old SIM Card and the new LTE card looked exactly the same as well, so there doesn't seem to be an easy way to tell if you have the LTE Enabled card. (Obviously if you were using it with an LTE phone before you know.) I was using a Nexus 4 prior to getting my One so HSPA+ was all I had available before.

You didn't need to give AT&T your IMEI. In fact, I try to avoid this with unlocked phones. You did, however, need an LTE Sim card to get the full benefit. You could have used your old card, but you would have had to enter a different APN manually and then you would only get HSPA speeds, which would be a shame.

[Q] Htc One GE and ATT LTE

Just set up ATT prepaid 60/month plan yesterday and its my understanding that this should give me LTE access. I found some att pta APN settings but they dont work, just lose internet connection. I am getting good speeds on HSPA (5-7mbps dl) but just curious as to why LTE seems to not be working?
Im on 4.3 if that makes a difference.

My first question is.. has AT&T rolled out LTE in your area? My second question would be are you absolutely sure your plan comes with LTE?

Nashville, TN so yes LTE market.
Asked the sales rep when I set it up yesterday specifically if the prepaid plans included LTE and he said yes.

Link to ATT PR about LTE with gophone plans, I have the 60/month option.

ok, next question, which APN are you using? bare with me, some questions may be redundant for you.

there's only a couple more things I can think of...
1. In your APN, make sure the bearer setting at the very bottom is unspecified (ignore if it doesn't exist).
2. The rep who created your account didn't enable LTE for the particular phone line.
Bottom line is, if LTE is enabled on your account, it should work.
sorry i couldn't help any more.

Cool well thanks for your help. I might swing by att store when I get off work and see if they figure out anything.
Overall really not that big a problem, hspa is plenty fast for me really, just want to get use out of what I pay for though.

I'm going to guess that the rep just didn't enable LTE on your phone line otherwise you'd have no data. Hopefully, they can sort it out.

Slow Download Speeds on T-Mobile

*** Caution***
I may have found a bug in the 4.4 software... I am not 100% sure, but it has T-Mobile perplexed beyond belief!
So, here is the issue. Without being on Wifi try downloading any file from the app store or any large file in general that is 100MBs and up.
From what I have noticed, my HSPA+ Speeds and LTE speeds are insane. Insane enough that I can stream Netflix in HD like its nothing - Over the phone.
So, in a way that makes things look even more weird. --- Here is the issue at hand, whenever I try to download a file that is over 100MBs or more the download will start out fast
and after a few minutes of download slow down ( basically get totally reduced to Throttling-Like speeds.)-- Same case with the tethering too! ( I tested this) This does not make sense, --- Comedy Here. http://youtu.be/6Xywqv1cDH8
So, I called up T-Mobile and they tried very hard to help me... it was actually insane because the customer service was so damn good. I got all the way up to American Tech Rep... guess it was that interesting, the guy reset my connection to my phone while we ran multiple speed tests. --- End result was that he could not figure out what the hell it was, and since NEXUS 5s are so new they don't know a lot about them. The tech had to send a trouble ticket to google or what not and I won't hear from the tech for 3 days.
It doesn't make much sense because I just got on their network like on the 9th... only used less than 3 GBs... -_- and IF they throttle its after 5GBs.
So if you are with T-Mobile or with a company in America and NOT on a Grandfathered plan post a quick result or kinda verify that your unit is or is not performing the same way. This is a very annoying issue.
ALSO, I am on the Unlimited verified Post-Paid plan too... so monthly and this is supposed to give cell tower priority.. or something.
If anyone has a way for me to fix this or is having similar issues let me know!

I ran these tests, but that won't help you unless you really pay attention and watch your download slow down.
You need to try downloading an app or any file above 100 MB and see if it totally slows down within the first few minutes.
Mine does this ALL the time.. Meaning, It won't do that if I am on Wifi.
As stated, I stared my service on the 9th of this month... so its Bull DOO DOO!

Can anyone on T-Mobile confirm what their APN is set on ??

I've had this problem with tmobile ever since I used the LTE hack on my N4 well over 6 months a go. I noticed it when i was on the APN with fast in it. The old HSPA+ one I was using before the LTE APN didn't have these problems. I know this doesn't help, but I've just accepted it as working as intended.

Name : T-Mobile LTE
APN: fast.tmobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Protocol: WAP 2.0
MCC: 310
MNC: 260
APN Type: default,supl,admin,dun,mms

I might have the same issue and I'm on T-Mobile. I'm downloading a 221MB game app at 23% completion with 7 hours left to complete the download
That 23% downloaded quick and now it's slowly downloading.

With one bar of LTE, indoors, (where my galaxy nexus couldn't get HSPA) I pulled 4.57Mbps down with two notable spikes on Ookla speedtest. I got 0.00up. I'll re-download 3d mark when I'm out and about. (It's 155mb) I also contribute background stats to Root Metrics Coverage Map. If your phone is rooted, consider playing with your TCP congestion control in Trickster mod or the like.

Name : T-Mobile GPRS
APN: fast.tmobile.com
MMSC: mms.msg.eng.t-mobile.com/mms/wapenc
MCC: 310

APN Type: default,supl,mms
APN Protocol: ipv6
I don't believe I made any manual changes to my APN. If I did, the only thing I changed was ipv6.

Same issue here OP so you're not alone.
Nexus 5 on T-Mobile, I have a super strong LTE signal at work but downloading anything from the playstore, like you say starts out fast 1.5-2MB/s then it goes down to a crawl after 70-100MB and basically seems to time out. I have to wait to go home to finish downloading on my WiFi connection. It's terrible and inconvenient to have to wait to go home to update a large application.

I am on T-Mobile and just downloaded Dead Trigger 2. Had the same speed through out the download and completed very quickly. I am not running a stock rom and maybe that is the issue?

I am on pre-paid. I noticed with tests it'll get to like 30Mbps at start, lag spike a few times, then finish at 4Mbps. I can't get upload to finish.
Sent from my Nexus 5 using XDA Premium 4 mobile app

Yep i have this exact issue, i can have full bars on LTE and it starts out at 30mbps then slows down to a crawl, like 2G speed. The only way i found to kick it is to switch to a wifi network then switch back to LTE, and it starts out fast again then slows down again. I'm on a postpaid plan with unlimited 4G.

EVERYONE I made a video with proof!
See it here! : Everything I am talking about is there..
http://youtu.be/2i3_lWWCJwg

The issue isn't just the app store, but downloads in general!
Another thing you will notice is if you are watching a movie via the Netflix app you will have super high quality meaning the connection isn't loosing speed.
Still want to point out that tethered downloads have the same issues.

Testing this right now by starting a download of Dead Trigger 2.
Well that didn't take long. At the 24mb mark I got throttled down to 0.02 mb/sec.

I have the exact same issue and am so glad you brought it up. Now I know I'm not alone.
I came from a htc one s and had similar issue. I thought it was the phone modem itself because the radio on that phone is a POS. Now with the Nexus 5,whenever I download a big file, it would start out with around 2 to 3 mb/s. And after a minute a two it would drop to low speed ranging from 15 to 150kb/s, constantly fluctuating.
Has anyone tested this on another phone? Maybe it's a t-mobile issue and not the phone itself.

No AT&T SIM

Has anyone in the US bought this phone? AT&T can't activate because they don't have the right (size I guess) SIM for this phone thus couldn't activate.
Anyone have this same issue?

That's BS. I slapped my nano SIM into my US XZ1C with no problems. The phone then asked to search online for the APN information. It downloaded it all with zero effort on my part and everything worked 100%. I've had this SIM card since at least the Z3 time. Go to another store, have them replace whatever SIM you have now with a nano SIM, go home and install it on your phone. Don't give them any explanation for anything. You need to replace your SIM with a nano SIM and that's it. You'll get signal automatically, but not data. Just Google AT&T APN settings and enter them if your phone doesn't offer to download them during the initial setup. I get LTE all over town, although it shows the 4G icon instead. I can send/receive SMS, MMS, and calls normally.

Ok I'll do that. I'm moving from vzn to att and was trying to set up account over the phone. The rep first told me it was a 2G only phone and they don't support that. Then after I told him that his own website said the IMEI number was supported he came back with the SIM statement. I even said "it's just a nano SIM" what's special... Anyway useless to argue after some point. I'll just go to the store tomorrow.

Go to a different one. It's a miracle that rep even knows what a phone looks like. "2G only phone"

Went to a store this morning and got it to sorta work but I'm only getting H+ on my phone, not LATE. Any thoughts?

have you looked at the APNs? this is most likely the issue.
this phone technically supports all ATT LTE bands.
you may also have to set your "Preferred Network type" to LTE preferred

I am still using my old AT&T SIM from years ago when it was originally a Micro SIM. Just carefully cut the SIM down to the appropriate size and it works fine. I have the UK version and have no issues so far.
As for the H+ only, it may be due to the IMEI not being recognized on the network carrier. I haven't experienced this issue, but from what I've read online, you can ask the AT&T rep to register your SIM using a phone's IMEI that is registered with AT&T. Not sure how that works, but it's what I've read on other forums from people with the same issue.

I've used APN settings on web and confirmed the SIM is compatible but still not getting LATE speed. Open signal testing in various locations at best are 5-6Mbps.

I believe I read somewhere that there is one band that is unavailable on the XZ1C in the United States. Could that perhaps be the band that covers the area or region that I am currently in?
I'm in college station, tx 77845

I'm really not sure what I'm looking for but found this site.

the only band i know of that has been in question is band 12. i think most ATT LTE takes place on band 17, which runs on almost the same frequency as band 12. this is likely not your issue, but i can dig a bit deeper. this mostly affects people using Tmobile, like myself.
i'm guessing you have one of the international variants?
that last link you sent was a dead end for me (your entries on that site did not carry over with the URL). what was it you saw on that site that was of potential value? you can send me a screenshot if you want

How would I tell? I double checked my order and confirmed it's "supposed" to be a US version and I don't have a fingerprint security option.
I doubt the resolution will be good enough to read, if not follow that link and apply filter Texas and Brazos country. It is a list of frequencies in my region. I don't know if it's of any real value or not just searching.
I really appreciate your help!

One last thing... My phone hasn't downloaded any at&t bloatware. Not even the myATT app. I don't know if that adds any clues

sorry to bother, would you mind sharing the APN settings you have?
also, any other network settings that might affect connectivity? our friend in texas needs some help getting his LTE going.
ALSO... my XZ1C shows LTE when connected to it. are you positive you are operating on LTE? is there a chance you are connected to it but not using it? network speeds?
thanks in advance!

Just left AT&T again and no better.
There are two APN settings that are on my phone. (1.) ATT Nextgenphone
(2.) ATT HSPA+ ***this was renamed from simply ATT by the guy messing with my phone. Originally it was just ATT***
APN Settings
1. These APN settings result in no data connection what-so-ever
Name: ATT Nextgenphone
APN: nexgenphone
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://mmsc.mobile.att.net
MMS Proxy: proxy.mobile.att.net
MMSPort: 80
MCC: 310
MNC: 410
Authentication type: not set
APN Type: default,admin,mms,supl,hipri,internet
APN Protocol: IPv4/IPv6
APN Roaming Protocol: IPv4
Bearer: Unspecified
MVNO type: none
2. This gets data (H) but at about 4 Gbps. Sometimes it bumps up to (H+) but never long enough to test speed.
Name: ATT HSPA+
APN: phone
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://mmsc.mobile.att.net
MMS Proxy: proxy.mobile.att.net
MMSPort: 80

APN Type: default,supl,mms,hipri
APN Protocol: IPv4
APN Roaming Protocol: IPv4
Bearer: Unspecified
MVNO type: none
Somewhere on the AT&T website there was detail referencing the 9th and 10th digit of the SIM being certain numbers. Whatever it was my SIM is compatible.
Looking for the specific langauge I happened back to this site and now I'm worried I've got no hope. Here is the link but I've attached a screenshot of the concerning statement.
https://apn.gishan.net/settings/1887_4_att_apn_settings_for_sony_xperia_xz1.php
Can anyone give an opinion on any of this? Thanks for all your help. I hope it prevents someone else from having the same problem.
