Slow 4G Lte - Galaxy S 4 Active Q&A, Help & Troubleshooting

Hello;
Got an unlocked At&t S4 active which I use outside the US and beside the tethering problem the 4G LTE seems really slow. Am only getting 7-8Mb/s via speedtest app. A friend of mine is getting 44Mb/s via speedtest webpage on his BlackBerry Q10 which he purchased locally. We were at the same room so it must be the phone. Any ideas how to get this fixed?

Using International HTC One with T-Mobile USA

Hi there,
I have an LTE International version of HTC One (unlocked).
When I'm traveling to the states every summer, i use a T-Mobile no contract SIM with my trusted N900 as a main phone and a wireless AP for my wife's internet (she also has an HTC one) and instead of my hotel connection.
I have a couple of questions:
Can I get 3G or 4G with my phone
Can I tether using this plan, or I have to use an alternative tethering app?
Will HTC one work with Ad-hoc wireless of JoikuSpot? (If i will end up using my N900)

the international version can pick up SOME t-mobile signals. off the bat probably LTE if your in an LTE area otherwise you'll atleast get 2g. if your in a re-farmed area you'll see 3g and HSDPA but depends on where you are as they arent completely done with the re-farming yet. as for the no contract sim being able to tether. i dont see a problem with it i assume its a prepaid? the phone should be able to push the connection through. though you're gonna want to be careful if you have a limit. on how much you can pull for internet
Thanks syaoran68,
I'll be visiting Los Angeles, but maybe another state, not sure yet.
I was just concerned that T-Mobile may be able to restrict tethering.

Running the S4 Active on T-Mobile, anything else I should do?

Hi all.
I have been using my AT&T S4 Active on T-Mobile for the past week. I got it unlocked via an eBay seller and everything has been working great thus far. I had a question though regarding bands and whether or not all the bands available to me are unlocked. Right now where I live I pick up 4G/LTE (although not as strong in my apartment and cuts in and out periodically). I had read that when you unlock a phone via the code it automatically unlocks the bands that were previously not available (when locked to AT&T). Another thread I read that the user has to still unlock those bands. I was hoping someone could clarify this and point me in the right direction! Thanks guys!

Are you able to use mobile data with only unlocking the phone? I am about to buy this phone but i heard after unlocking only call/sms will work and not data.
I read here that for data we need to do other stuff
This phone says " LTE Bands 2, 4, 5 and 17" on AT&T website and I'm wondering if this phone will work on other carriers LTE network(T-Mobile, Verizon, or others?)? I know Verizon is CDMA and at&t and T-Mobile are GSM but can anyone answer this?

I got the AT&T SGH-i537 model. Pay $15 to have it unlock. Now using it with T-mobile. I got LTE. In some area, I got 23mbps download and 3.6mbps upload. It doubled my Galaxy Nexus speed. The device status info said I am on LTE:14
However, my mobile tethering is disabled. Need to find a way to enable that. Stupid AT&T lock it.
As long as you have the correct setting input into your phone your data will work ( assuming you have a data plan). I remember when the original Iphone came out I unlocked it for T-mobile and had internet on it even though it was branded AT&T only. (EDGE lol 56kb speed) but still it worked...
Root
I unlocked mine with ATT and used it with TMobile while I was in Hawaii. I only had to put my SIM in and I got pretty fast speeds (around 22mbps from what I remember) I don't know if that's the normal speed but compared to the crappy speeds on Guam it was lightening speeds to me! No root or anything needed, no difference after rooting either.
i can confirm it works minus teathering due to att
This is interesting as I thought ATT phones cannot receive Tmobiles LTE.

Unlocked Samsung Galaxy S6 on Straight Talk

Hello everyone!
I just bought an att samsung galaxy s6 and had it unlocked. I currently have straight talk service and it is completely horrible! The coverage map shows excellent service in my area. My friends have straight talk service and their phones have awesome service and blazing fast 4g lte speeds. My friends have branded straight talk phones (like galaxy s3 etc). My att S6 is horrible though.
Im sitting beside my friend right now. He has straight talk branded galaxy s3. Both his phone and my phone are both GSM sim phones using the same band and towers. We both installed speedtest app and used the exact same test server. He would go first and I would go when his speed test was finished. My friend got like 35 mbits down and 17 mbits up. I got 1 mbit down and 0.76 mbit up.
I have called tech support about 20 times trying to figure out why my phone is so slow but nobody can figure it out. I have heard ever excuse from my phone needs factory data reset to my phone uses different towers than my friends phones (which one has an unlocked att s4 phone).
Does anyone know why my phone is so slow and my friends phones are blazing fast? Any help is appreciated.
Oh, btw... my phone and my friends phones have exact same apn setting etc.
StraighTalk have 2 different Sim Card, one for the T-Mobile phone and one for the AT&T version, make sure you got the AT&T version, cause if you have the T-Mobile one, the reception is horrible. That happed to me and I order a new AT&T version Sim card from them and that solve the problem.
I do have the att sim card in my phone. I bought the byop kit and it has the tmobile sum still in the package. Tech support also says I have the correct sim and everything is provisioned correctly on their end. I've verified my sim card number with about 4 different techs.

LTE speeds (DQA error(?))

Hello guys,
I just noticed my LTE speeds were horrible (2.24 M/b download/2.03 M/b upload via internet speed test). My coworker who is using a Samsung Galaxy Note 5 on Verizon is achieving speeds well over 20 M/b. Neither of us are connected to WIFI. I tried to do some research to see if anyone else was having the same issue but haven't found anything on it yet. I got really good speeds on my S6 before the upgrade. I tried to phone in with Verizon's tech support and they weren't much help. I'm wondering if this might have anything to do with the DQA pop-up errors. Hoping an update would fix it but just wanted to isolate the issue if it's software or hardware-related.
Has anyone experience similar issues?

I am not using verizon network but i am using a verizon s8 on a different network and already using the latest update. i am able to get 37Mbps for download and 27Mbps Upload speed on my company so i dont think your problems are related to the update but to verizon itself

Anybody on Verizon able to check if their LTE speeds have been bad? I could just rule out that I am in bad area but since I have other coworkers getting better speeds just trying the diagnose the problem.
Thank you all,
Thought the dqa is for wifi only
I'd say they're pretty damn good on this phone.
47mb down
20mb up
in KS, testing a Dallas server on speedof.me
Sometimes, this is due to a bad sim. Did you get a new sim for the S8?

Who do you use on your Verizon S8? I am using at&t but can't get LTE connection to stick. I boot the phone, I have LTE for 2 minutes and then back to HSPA+
Wondering if you are on at&t as well?
Thanks

I am using ATT but in Mexico and here ATT only use band 4 and 5 so i dont have any issue. I use ATT (roaming) every time I am there and I do notice that with my old phone (HTC 10) in my area this phone was constantly using band 30 and 4 and changing between them, so after I changed to the verizon s8 I lost band 30 and i was only able to connect using band 4 hence some times i was losing my LTE.
You should do the test with your old phone and LTE discovery and see what bands are you using most of the time and see if your verizon phone have them or not.
I am also having this issue after the update. Slow LTE speeds even when I am in line of site of a tower.

Cricket, Att Will this work?

Hi all, will this phone work on ATT and or Cricket? Is it a GSM phone? Will it get 4G if so? Thanks!!!
i have the mix on Cricket since December, it's on H+ most of the time and some times 4g depends on your location I guess, so it works on cricket and I'm not complaining on internet speed

I use it on Straight Talk (the AT&T sim). I live in Springfield Missouri and normally get LTE everywhere I go. The only real issue I have is when I do happen to lose LTE (receive/make a phone call, lose LTE in one particular room at my work, etc) it will stay on H+/3G until I go into settings and toggle between 3G then back to LTE again. Sucks, but not that big a deal since Straight Talk basically caps speed around 7-10 megs and H+/3G pretty much handles that speed anyway. But I haven't really had that many issues.
Mine is on Cricket and running fine in the Des Moines, IA area. I have a few hiccups here and there, but nothing drastic.
I have it with Att and works great always on Lte (tucson,Az). I get the hd voice and video calling as well. Only complain is I cant wait for mix 2 lol.
Straight talk ATT sim LTE all the time I live south of Chicago
