Unlocked Galaxy s8+ (G955U) getting extremely slow LTE speeds on Cricket - - Samsung Galaxy S8+ Questions & Answers

Backstory: I purchased this phone from Samsung because of the trade-in promotion they were running. I traded in my AT&T Note 5 (N920A) where I had great LTE coverage in most places around where I work/live, unless I was in an area of a building that restricted reception. Before the N920A I had the international Note 5 (N920I) and it worked great on LTE as well.
I live in a suburb of Nashville, and the Cricket coverage map shows great LTE coverage where I work and live (I live less than a mile from where I work) but I'm getting less than .5mbit down/up around this areaeven though my phone shows that I have 4 bars LTE. With that said, there are other areas around town where my LTE is just fine and I get the advertised 8mbit download speeds that Cricket offers.
Are we sure that this unlocked version of the S8+ has all of the LTE bands enabled with its stock firmware? Apparently is has all of the bands, but do I need to flash to the AT&T firmware in order for them to be activated?

AT&T LTE slower than HSPA?

I have given my IMEI to AT&T and the 'LTE' symbol appears correctly.
Speed test reports regularly 4-8 Mbs when 'H' is showing. But when 'LTE' shows, I can't get results above 1-2 Mbs. Anything under 3 is LTE, over is H:

Kinda weird and frustrating. Any ideas why? I've tried different areas. Do I need to do some manual APN tinkering, even in this day and age?
Here are the defaults when inserting their SIM card:
I'm also setting weird erratic results like upload speed 4 times faster than download.

You did 3 LTE speed tests within 3 minutes then waited another 2 hours and compared it to one done on HSPA. Not sure what the busy hours are on the eNB's around you but generally we would do the tests at the same time of day. Have you tried doing the speed test at a different location as well? I'd go at least 4KM away from your current location to make sure you are on a different eNB to verify it's the UE or that particular eNB which is limiting TPUT.
I went further away and the speed rose to 13 Mbs which was a relief.
Still disappointing that, at any time of day, in my area LTE is slower than H on AT&T.

I'll also say, make sure you check the server that the Speedtest.net app picks... For some reason, lately I've found it to be a little wonky... I (and some friends) have been getting hit with servers that are half way across the country. Eg; I live in WV, and it's given me servers in NY, WA, FL, and a few others, all while inside either my home or a friends house in town.

Perhaps the eNB has some limitations on the backhaul..
If I were to deploy a network to compete with VZW, I would quickly deploy LTE coverage (i.e. you see LTE show up on your status bar all over town) but then take my time and throw less $$ on capacity and optimization. But that's me.
I am also getting weird results with LTE on AT&T. I have the same APN settings as OP. I have not had LTE before, so they had to change my old 2 GB Galaxy S 2 data plan to some other 2 GB LTE-enabled plan.
All the results, except for the top (which was run w/ forced 3G) are on LTE. All the tests occurred indoors, with a few consecutive ones in the middle conducted outdoors.
Why is the upload faster than the download!?!?!?
I also had this problem about two months ago do to the fact at&t was not finish updating there towers here at my location now I'm getting great speeds

New thread created. Sorry. But I think posting your full APNs could help others solve your issue.
New Nexus 5 here -
On a Net10 SIM using AT&T and APN set correctly (tfdata) - LTE appears in the Nexus status bar - but, faster speeds with HSPA+ (on download), although ping is a bit better with LTE.
This is in Honolulu.
Speedtest.net selects Florida as default "closest server" when on LTE, and Oklahoma when on 3G; the closest I can actually change to on LTE is Texas. So, with Texas selected - LTE gives me 2.34mbps down, 5.68up and 170 ping; 3G HSPA+ gives me 5.71 down, 1.13up with 204ms ping.
Definitely not impressive for LTE.
Have tried 4x over several hours.
don't think signal strength is the issue as getting -84dbm/56asu on LTE.
although the 3G signal is even stronger at -67dbm/24asu.

I've had stellar results for every test of LTE with my 5 on AT&T
http://www.speedtest.net/my-result/a/640381244
I belive its something to do with the speed test app itself. I have AT&T, Verizon and Tmobile.
Before I use to get 42-50 on AT&T on the Gs4 and iphone 5. Same with Verizon and Tmobile.
Since the last update to the app Im getting 2-3mbs down and 5 up on all my phones across all networks. My iphone 5s is on Verizon and is having the same problem..
But I know the speed test is wrong because the speed in which I download apps is very fast and web browser is at LTE speeds.
I disagree. When it shows 1 Mbps LTE, downloading a huge app from the Play Store crawls along. For me, it's not the Speed test app.
Remember this thread is about LTE though.

I thinks its fair and logical based on mountains of evidence across the forums that there isn't an issue with LTE on this device with AT&T. If your seeing slow speeds its just the network being slow or the location your speedtest app is connected to is slow. Lots and lots of people are on this phone with AT&T without issue.
I'll admit that my results with SpeedTest are inconsistent, and mostly based on what server is used for testing. When I am offered a local server (Hartford, Boston or NYC), I get relatively high scores on both AT&T and T-Mobile. When I am offered servers a long distance away (say, Overland Park KS), my scores are much lower... even from the same tower at the same time.
I feel like my LTE is much slower than on my S4 in the same areas. Also gave ATT my SIM and IMEI.

It could also just be a messed up tower. That's not, necessarily, indicative of overall LTE speed.
I had slow or no connection on the pre programmed settings, I changed the APN from phone to pta and that fixed my issue.

at home, my N5 LTE is just a little bit faster DL than HSPA+. At work, it flies. Might be the equipment in your neck of the woods?

[Q] Nexus 5 No LTE - AT&T

Just visit your ATT store or call them. I was stuck with H for a day until they had to create a service request for a higher tech person to fix it.
Make sure they prevision your plan to "4G LTE". It can be taken care of over the phone.
I have the same issue, however I'm on a dealer line so I can't have customer service change it, I have to have my rep do it and he is having trouble figuring it out, and so my at&t rep says that he thinks its because I didn't have an LTE phone prior to this (nexus 4) so he is gonna try to change my imei to his G2 he doesn't use

Ah ok then make sure they provision your imei to work! Make sure to talk to a tier 2 representative if the first person doesn't do it or something

I remember reading in another thread that the IMEIs on the n5 don't register as an lte capable phone in AT&Ts system. You may need to obtain one from a phone that is confirmed to work on their LTE, or have CS generate one for you by telling them you can't find yours. Wish I could find the thread, but they get buried so fast around here.
Keep in mind that this info was from a few days ago so it could just be that AT&T wasn't prepared for the launch...they may have already fixed the problem.

If you put in a sim card from a HSPA only phone before switching to LTE or a new sim then you may need to do a factory reset. That was the only solution that worked to get me on LTE as I was also stuck on HSPA. Could be worth a shot if you don't figure it out.
Yeah just had to call at&t to have them re-switch on my LTE. When I was using an old iPhone 3gs they "turn it off". Thanks for all the support!

[Q] LG G pro 3G issue.

Hi guys, when you have time would you throw an eye on this thread.Merry Christmas to everyone, how are you?
I just bought recently unlocked AT&T made in Korea LG optimus G pro e980
The kernel is of AT&T because when i start the phone i see the logo of AT&T mobile.
I am on Walmart Family mobile plan they are OVN of T-Mobile. I am on unlimited text,data,talk plan, it is included 2 GB of 3G data.
The android version of the phone is 4.1.2, baseband version APQ8064,MDM9X15m Kernel 3.4.0, build number JZO54K,software version E98010k

On the top corner of the screen above the network coverage stays the letter "E" (EDGE) and the internet is very slow!
I've seen they are many AT&T brand applications are installed on the device like: at&t drive mode, at&t Locker, at&t Navigator e.t.c.
Please guys what you would suggest me what i have to do. Do i need to root, to unlock the boot loader, or to change the base bands to get the 3G coverage or what? I would be thankful if you answer me with links or step by step what i have to do, because i am newbie in this area, i have experience in desktop pc, laptops, some software and hardware knowledge, i am mint in smartphones.
ck.
I live now in Bryans Road, Maryland this area is 3G covered i already checked.
When i search on networks in the phone i also see signals from AT&T antennas like AT&T RAT:14,3,2 and three for Family mobile.
Thank you. Mr. Stark recommend me to change the preferred network to 3G or LTE in settings, i am still trying to find where is that in my phone, but can't find it

[Q] D6603 T-Mobile LTE extremely slow?

I swapped from the D6616 Z3 to the D6603 Z3 because I didn't want to be locked into T-Mobile just incase my family and I end up swapping to AT&T early next year. The issue I'm running into is, I inserted the nano-sim and messaging/calls work on the D6603, but data didn't. I looked all over and did the following:
Settings->"more" (under the wireless/network) -> internet settings and connected to TMobile. The APN appears "T-Mobile Data" now. Internet connects, woohoo!
The issue I'm running into is, the LTE appears, and it is now connected to the internet, but it EXTREMELY slow. Speed test shows .15-.20 MBPS whereas before I was getting 8-9 in the exact same spot. I swapped the sim back to the Samsung Galaxy Nexus and I'm getting faster speeds on "HSPA".
Any ideas or a different way to connect the D6603 model to T-mobile's data?

I'm using the D6603 on AT&T, and LTE is quick. I think each of those phones have different bands. The D6616 is the T-Mobile model and the 6603 has AT&T bands. I think a lot of the LTE bands overlap though... Maybe LTE is slow in your area? Does your service show up as LTE at the top by the signal?
Also, go to your quick settings menu in the notification pulldown menu. There should be a box for "LTE". Tap and hold it and click on network settings. You can change the preferred network mode and see if the HSPA is faster

Try to set the "APN protocol:" to IPv4/ IPv6 instead of just IPv6. See if it will be any better.
Did what both of your advices. First, I switched it to HSPA, speed test hit 5-6mbps. Re-connected to LTE afterwards and it hit 10-12mbps. Loads webpages just fine, and was able to play games.
Then went and swapped the IPv6 to IPv4/6 and I clocked 16mbps twice.
Not sure what else happened or what caused it to work randomly after going from LTE->HSPA->LTE, but it worked.
Went and installed the nillkin screen protectors as well, and I must say, it is a great upgrade from my old samsung galaxy nexus. Thank you for the help guys!
