T-Mobile US Data Mobile Network Question - Xperia Play Q&A, Help & Troubleshooting

So I have a unlocked att xperia plat on T-Mobile. In my areabthebrefarkijg is complete and. I get hspa but only when I am about halfback mile down the street. I live at the base of some good size moutains and have been told that is why I am on edge data until I get further away from the mountains. I also have a tmobile signal booster that was provided by tmo. That being said in my house I have no dropped Calla but again unless I am on wifi at my house I am on edge.
My sister came by. She just got the tmo nexus 4 which with Tue current version of firmware doesn't support tmo lte in this area, yes I know I can downgrade the firmware for my sister hut she doesn't want to mess with it.
I was helping her set up her phone tonight and noticed she had 3 bars of hspa. Whereas o get no bars of hspa only 2-3 bars edge. I have the same apn settings as hers. Any ideas why her phone would get it and mine doesn't? Again immune areas tmo has converted to hspa att compatible signal. I am running the latest ftf with the .79 basrband
Could it just be hers is an official tmo phone and mine isn't? I checked all the apn settings, I checked to see in mobile networks if there was a 3G for tmo signal and all I got was 2G. Whereas my sisters phone was 3G on tmo. Not a big deal as I have excellent speed on my home network. Just curious. Thoughts anyone?

Also forgot to ask. I know there are the 3G speed/network scripts floating around here. Has anyone used it and if so are they worth it? Do they work at increasing 3G data signal, etc.?

Set up and test Nexus is on ATT "4g"

I'm posting this info as I searched for 3 hours and couldn't easily find this info concerning setting up a nexus on att.
First off I'm 99.9 sure that the nexus never displays 'H+' like some other samsungs. So if you don't see 'H+' it doesn't mean that your not on H+.
The only way I found that is sure is in to go to: about phone->status->mobile network type. When the phone is not using data it shows hsdpa:9. When the phone is using data and it is on H+ it will show hspap:15.
If you continue to see hsdpa:9 you need to correct your data plan to a 4g plan or fix your APNs.
H+ is not in the system UI, hspap is displayed as hspa on 4.0.4, I have att as well

HSPAP
I'm running 4.04 and show HSPAP.
Go into the system information option in settings and click on "status" if hsdpa:9 is shown you have hsdpa, if hsdpa:15 is displayed you have hsdpa+.
Sent from my Galaxy Nexus using XDA
So I am on ATT with the standard $25 data plan and I only ever see hsdpa:9. What do I need to do to be able to get hsdpa:15 or hspa+? I havent registered the phone with them or anything, and am using the "3G" sim from my old captivate. I am running the latest stock 4.04.

it's mostly a problem of the towers. some of them either don't support hsdpa+.
or your signal is not strong enough for hsdpa+ so get pulled down to normal hsdpa.
Those of you with ATT and getting hsdpa:15...which radio are you running?
att settings
Here's what I did:
make sure your data plan with att is set right. if its not you'll never get it to work. mine works on 4g with 'smartphone 4g' plan. att wont recognize your imei as a smartphone so wont be able to configure a data plan. you need to give them an imei from an att 4g phone or borrow one or have someone at the att store put in the imei from one of the store demo phones or whatever but if you don't get a 4g plan it will never work.
for apn's is use 'phone' for 'default,supl,mms'. google the details.

4G LTE On Verizon PRL

So this was strange.
Riding the bus in Los Angeles listening to music and surfing the web on my phone when LTE pops up. Now as you can see I have PRL 1 which forces roaming on Verizon towers. I checked my speeds to see if this was indeed true and I was hitting 16mbps+.
This lasted about a minute until I moved out of the area and signal went back to 3G.
Anyone can explain?

Sure, you rode by a Sprint tower that was broadcasting LTE. You can't connect to Verizon LTE as you don't have the proper hardware (VZW LTE: 700 mhz, Sprint LTE: 1900 mhz)

That doesn't explain why I don't get LTE signal on the Verizon PRL on spots I know to have Sprint LTE though. For example at home I get a steady LTE signal -although at joke speeds. sometimes I'll be hitting 4mbps other times I'll get lucky if i even hit 1mbps- but I'll still use PRL 1 and not get Sprint LTE.
So was this a glitch that made me jump on Sprint tower although I was on forced roaming?
I think of going back and testing if this happens again. For anyone in LA, this was in Figueroa and Colorado Pasadena, CA
Dude I'm rocking the same prl and I live were Verizon has lte I don't get lte .so you just lucky and live by were they're testing sprint lte

Nice to sew there is some signs of lte in pasadena. I was in west covina over the weekend and there was no lte. There is some in el Monte apparently.
But Sprint LTE is different from PRL as PRL is just for 3g and the gs3 had two antennas .

This has been explained numerous times... when you are roaming (on Verizon) but you have an LTE connection, it is two different signals. You are getting EVDO/1xRTT coverage from Verizon and LTE coverage from Sprint... no one on Sprint is roaming Verizon's LTE. Two different frequency spectrums of throughput.

Actually, I think the OP meant it's impossible to grab Sprint's LTE 1900 on a Verizon only PRL. Due to common belief, it's said you must be on a Sprint PRL that has LTE enabled to connect to it. The OP's situation is a rare one.
I wonder if Digiblur can enlighten us here, since I've always believed you needed a Sprint-Only LTE capable PRL to connect to Sprint's LTE network.

Exactly this.
I wasn't aware I could jump to Sprint LTE on a Verizon only PRL considering in areas I do get Sprint LTE coverage, I won't get 4G unless I update my PRL to a Sprint one.
I hit 13mbit near the bathrooms at the universal studios Hollywood Jurassic parking lot the other week. LAX only had 8mbit LTE

Can't you just check your assigned LTE IP address to see if it was issued by Verizon or not?
I bet if you look at the LTE engineering screens it shows a Sprint PCS G block connection. From what I have seen in the past, you do need a PRL with the MCC/MNC records for that Geo. I have seen the Nexus not need this, probably because it doesn't have a qualcomm chipset.

Will someone please link me to the file for PRL version 1? (assuming this is still the best option) I am in a rural area where Verizon has 4Glte but sprint data sucks. I've searched but can't find it. Also, if I switch to s stock rooted rom, flash it, and then recover my current rom (Eclipse), will the PRL stick or revert back to what it was?
Thanks,

I don't believe that is possible. Verizon and sprint use different frequencies for lte. They only share 3g and 2g frequency.

I found 1,2,3 and a couple others but none of them will give me 3g but I know it's here. I wasn't trying to get 4g, as nice as it would be.

I don't get Hspa+ connection everywhere.

I have a Note II Factory unlocked international edition. I also have a $30 Prepaid plan from T-Mobile which is supposed to give me 4G speeds. I dont get them everywhere. At my house i get the 4G speed however when i go to my school which is a mile away. I only get Edge Connection and sometimes out of the blue i get 4G speed back again. Whats wrong with my phone not gewtting those speeds everywhere? its really annoying
My guess is their 4G isn't rolled out wherever your school is.
Or it could be the signal being blocked by all the walls and **** in your school.
It's not a problem with your phone, it's the network itself.

I just got my 7100 unlocked as well and I am on the same plan you are on (its a great deal right?). I have the same problem, I'm stuck on EDGE at home (I'm on wi-fi so its not a big deal) but when I am at work my phone goes crazy. It will switch between H+, H, 3g and EDGE all day long. It will have seizures. The crazy thing is, work is about 10 away from my house so....???
I've been trying to unlock the 1700 band but it may not be possible on the GT-7100. when hitting *#7284#. You're supposed to go into the "Qualcomm usb settings" but that option does not exist on my phone. Anywhere. Its just not there. So I'm stuck.
I know Tmobile is in the process of refarming their network to 1900, but I have no idea when they are going to complete that project. Anyone know?
It may turn out that we'll have to either put up with the EDGE speeds or go with Straight Talk...
Pretty much what the guy beneath you has said. I not every provider guarantees that you will get the same speed everywhere. Not even to mention that tmobile is the only major provider in europe with very very bad coverage.

Unlocked AT&T S3 I747 for MetroPCS/TMobile

Has anyone here bought an unlocked AT&T S3 to use on the MetroPCS/Tmobile network? If so has there been any issues? shorter battery life, bad connectivity?
I am debating getting the S3 unlocked or HTC One S. I would prefer the HTC One S but it doesn't have microSD slot

Is that the same model as my phone? So it would be advisable, after I got the S3 to flash it with a MetroPCS ROM after activation by Metro?
I thought there would be no need of a flash if I got an unlocked phone.

You will have issues with 3G HSPA+ on 1700mhz, but 2G EDGE & 4G LTE will work just fine. If you live in a large metro area with a lot of LTE coverage it will be fine. I just went through this with my wife's phone, she had to have the Red one (AT&T specific).

There is no need to flash anything, just unlock it and add/edit the APN for TMo.

Sweet thanks! Both areas that I frequent have 4G and LTE coverage. My only concern is when I'm driving long distances which I often do, being in college and losing 2G signal in the middle of no where. So far with my Metro phones, I haven't seen anywhere I had 3G coverage. its always 2G and 4G/LTE

Good, that is exactly what we are seeing as well. Mostly LTE coverage with EDGE to fallback on. Most all Metro areas and major highways/interstates will have good coverage. Funny enough we live in the middle of nowhere, but there is a major highway nearby so we get LTE coverage.
On a side note, US carriers marketed HSPA as 3G and HSPA+ as 4g, but both are technically 3G. True 4G is LTE. I am not sure if Metro ever had HSPA service, I think that they were just CDMA then later added LTE and have been migrated to TMo's GSM/HSPA network which now uses Metro's LTE as well. Only the newer GSM Based phones would connect to HSPA.

Given this is not an LTE device, that sounds about right. Weather, tower congestion do affect results.

The I747 is an LTE device, my wife's (running on TMo) works just fine on LTE, just not HSPA+ 1700MHz. I'll run speed test if people would like.
Unlocked att siii will not access metro/t-mobile data
Can someone verify for me what the correct apn settings are? Should there be a network operator? And since I think the apn is finally right, do you have any more suggestions? Also, do you know if this is CDMA or GSM?
can I ask why people want to buy an ATT phone to use on a Tmobile carrier? On the S4 and Note versions, people buy Tmobile phones and use them on ATT, myself included. This is because of the bootloader, and the Tmobile phones cover ATT LTE channels while not the opposite.
Wasn't planned
I didn't intentionally set out to buy an AT&T phone, I was just looking to upgrade and this was the best deal. Or at least it looked to be on the surface. Do I just need to forget it and try to sell it?
If you are in an area recently upgraded by T-Mobile, the I747 will work just fine. However, if you are in an are not upgraded with LTE, etc, it's waay more trouble than its worth. The above post about not getting HSPA+21/42 is worth considering too though.
T-Mobile and AT&T are both GSM networks btw.

I am actually on Metro P.S, but they are on the T-mobile network now in Atlanta, Ga where I live. We do run 4glte,but so far the fastest mine will connect to shows "E" on my phone, edge maybe? One of the many I've spoken with at metro said E is 3g. One of their repair techs said I needed a different SIM card because I had a CDMA phone but when I got to the store that had one he said it was a GSM phone. It's already about been more trouble than it is worth, but as much effort as I've put into it already, I'd like to resolve it.

ATT note 2 as go phone

I have a att note 2 with a go phone sim card in it. I get hsdpa+ but can not get lte. When the sim card was bought it was used in a vzw note 2 would that effect it cause the vzw note 2 imei number was used to activate the sim. All the ready I have done someone said somewhere that the sim is probably not provisioned for lte. Well the point im getting at is I need help in trying to get lte and I know where im at there is lte cause my Co workers are currently on lte.

If you are on a go-phone plan I would be very careful using mobile data. My wife doesn't use her phone much so she has a go-phone plan. I experimented with it some and a couple of apps got updated via mobile and it ate her $$ up in a hurry -- something to the tune of $17 in just a couple of minutes.
Then again there are a couple of different go-phone plans so this might not be the case for yours.

Sorry but h+ is not lte. And according to documents on att.com and other varies websites you can connect to lte with this phone on go phone plans
It is LTE if the rom doesn't have an LTE icon.
And how do you know you are in an LTE area? I'm in a large California city, and I almost never see the LTE icon.
HSPA+ is considered "4G" by ATT, but it is not 4G LTE.
AT&T 4g icon... yaya
At&t stock roms will show 4g icon in the status bar for both HSPA+ and LTE. This is where the confusion starts yay AT&T.
To check to see if you are on LTE I would go to settings / about phone / Status and check the mobile network type. I think this will give you a better indication of the network you are on.
An information app similar to https://play.google.com/store/apps/details?id=gdip.android.network may also help.
If you are still not getting LTE with your at&t go phone I would start by checking your apn settings.
I have used a few of at&t mvno's I have had straight talk, at&t-go, and currently prefer(and use) AIO wireless (now re-branded to Cricket). All of at&t mvno's don't even require you to unlock your carrier you can use any at&t phone on their networks.
I hope this clears things up a bit.
I've checked apn settings they are what it should be and in the settings menu it reads hspa+. And where I live and work both have lte. Gettysburg pa is where I live and I work in baltimore,md and people I know all have lte. I called customer service and they could see I was in a lte area and only receiving hspa+. They have a trouble ticket in. I know the icon in the notification bar always shows 4g thats why Ilike to always go off setting/about. Thank you for your help

you need a new sim, you can get LTE with at&t prepaid but if you have an older sim,it wont work. i had a note 1 on postpaid and was only getting h+ until i went to the at&t store and got a newer sim.
some people will try to say there is no lte on at&t prepaid,there is.

I agree with getting a new sim. Go to a corporate/retail store not a dealer/franchise store, as the corporate will give you a new reprovisioned sim and the dealer will say it won't matter, or charge you.
I just saw the LTE icon for the first time, but I am far away from my home now.
