Slow speeds? Poor reception? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Recently came from the lg optimus g to this. When I had the G it consistently ran on 4g lte speeds of 15-18 , even saw 21 mbps download ....now on this its rarely above 3/5 bars and hd on youtube takes ages to load...normally id think att docked my speed because im over 5gbs but ive only had this device since sunday and todays the 5th .
Whats going on?
Edit: my galaxy is 100% stock
Stock rom, not rooted, everything stock

Check your apn settings. If it is set to pta, switch to phone.

Terrible Data Speeds

Anyone else getting speeds like these?
Or anyone been able to fix this problem?
Attached are my APN settings. I've read the whole APN thread but got no definite answers. I also called AT&T and they said one of my towers might be down. I doubt that every tower on my commute for 60 miles is down though.

Make sure they have you on the 4g smartphone plan and then Google Atrix 4g APN settings and input those. If everything is set up right you will get better speeds.

Results after new APN. Also called AT&T and they confirmed I am on the 4G plan.
Also after new APN I can't send or receive MMS.

You should have 4 apns if you used the Atrix 4g apns. One for HSDPA one for tether one for MMS and one for the regular WAP.Cingular. I use them and I get a constant 5 meg down and 1 up.

Do I need to do anything specific after inputting the settings? I find it weird that I have data but even slower now and no MMS.

Select the radio button for HSDPA and then reboot your phone.

It's not working on my either and the LTE option was already chosen.
I believe they screwed up on this, they'll probably fix this with an update.
They're setting us up. They're not gonna give it to us until the 4g lte price hike.

Funny I get 4g like no body's business. I stay connected even more so than my daughter's evo lte.
Try set to home only (sprint) under roaming. Notice my data is a whole lot stable compare to automatic.
Yeah it works...i get 4g. It connects automatically

After Jb OTA am getting 4G in status bar when Orange needs 3 years to provide it!

How could this happen!! My phone is a T-Mobile T999 unlocked and working on Jordanian Orange. According to orange they will begin providing 4g in 2015 yet in status bar I see that am connected to 4g. Could the T-Mobile build be exaggerating figures ??

Mine always shows 4g...Although truly I am not always connected to 4g.
Just run a speed test and you will see.
Sent from my SGH-T999 using xda app-developers app
Most phones would show H or H+. The T999 was coded to show 4G instead, in keeping with their ad campaign.
If you go into settings, about device, status, under network type itll say UMTS at idle and probably HSPAP when under load.

IOT Hidden Menu

For those of you that have good lte/ehrpd service in your area I found a little trick to turn on lte only and ehrpd only mode.
Go into ##data# select edit, select others, then select HDR/1x selection I found this out today. Sorry if in wrong thread, a good way to check if you have lte in your area try the sensorly app free on play store
I dont have HDR/1x section!?

Are you on LJC? Or LJ1
thanks...i already know I have lte in my area but we dont have ehrpd and I have been looking for a way to turn it off. on the evo lte tirning it off drastically improved 3g speeds
still playing...so far turning it off does not stick.

Have you tried going to data edit ehrpd menu then select ehrpd you should be able to turn it off like that

those playing with this note...phone calls will not work on lte only
indeed...doesnt seem to stick unless i choose cdma only. wife distracted me tho so havent seriously toyed with it.
hybrid seems to stick...ehrpd stays off and most consistant 3g connection
cdma only was garbage (.02 down and .04 up)
going to test more tomorrow from other locations.

well...so far hybrid may make a difference if there is no lte available... but my tests really have shown nothing conclusive.
for me in my area (lte) it apears to work best on the default setting.
still a cool menu to play with

Cm10.1 data switching issue

When I turn on my data it switches between 3g and 4g and I can't even figure it out
Sent from my SGH-T999 using xda app-developers app
That is how it is supposed to work, nothing to figure out.
My gfs phones never switches or anything my phones does all the time
Sent from my SGH-T999 using xda app-developers app
What is she on and it never switches to what? If she hasn't updated her modem it will stay on 3g all the time. It is like this on every AOSP rom for our phone. Unless there is a theme that edits it out.
If speedtest says it's fine, it's fine.
It just switches from 4g to 3g all the time but I guess I'll have to live with it

Its how its suppose to work. H shows when cell data is accessed and when idle it shows 3g... Not sure why it bugs some people.
