manual select available cellular networks?

hello,
can you guys pick up different signal carrier in your hd7?
i am using T-mobile HD7 and the signal is not stable in my place (i have few drop calls). the Verizon signal is much better and i can pick it up from this menu >start>setting>cellular>network selection>
I can force the phone using Verizon, but the problem is after the choosing, the cellphone did not show any signal bars. <most likely phone can not register in the network>. it is wired. any ideas?

tmobile phones cannot use cdma networks, different radios, different technologies.

can a AT&T or cellular network be used in this phone? t-mobile signal is so terrible in my place.

yes you can use at&t if you sim unlock your phone. T-mobile might do it for you or you can pay one of the web based companies that do it.
You won't have 3g though.
Why did you get a t-mobile phone if you don't have t-mobile reception???

nope. AT&T work off different network signal than the others do so you won't have much luck. and i'm not sure if the HD7 from t-mobile supports the band (network signal) that AT&T uses. so you could try but i highly doubt it.

t-mobile signal is not good in my place.
to be honest with you, I hate AT&T and verizon.

[Q] at&t 4g on unlocked tmobile galaxy s3??

I have a unlocked t mobile galaxy s3 I'm using on at&t network and I only get 3g but my download speeds are 4 to 5 mb. Which is pretty decent but I was wondering if there was a way to get AT&T 4g? Maybe it's my apn setting issue? Any tips.....

What data plan are you on (medianet/dumb phone, fauxG, LTE)? I've rarely had issues with my unlocked phones having the wrong APN on AT&T, but here are the APNs: medianet is wap.cingular, 4G/HSPA+ is phone, and 4G LTE is pta.
That's about what I get on medianet. I've got as high as 8Mbps on pta but it varies and it's never been consistent for me. 3-5Mbps is normal for my HSPA+ in my area (Olympia, WA). I get about the same speeds in southern CA and tended to get better speeds by 1-2Mbps in Austin, TX.
If you're asking if it's possible to get LTE on the T999, I have no idea. ;P The MSM8960 (S4 SoC in both phones) does support it natively but I don't know if it's possible to enable the LTE modem in software. You could try flashing an AT&T modem but I doubt it's that simple.

Ok maybe I'm wrong but isn't the t-mobile galaxy s3 the only one that didn't come lte equipped because t-mobile uses hspa+?

Hey I have a question regarding this topic and the quote above. You listed the Apn's with its respective data plan:
1. wap.cingular = non-smartphone (i'll refrain myself from calling it a dumb phone plan lol).
2. Phone = 4G/H+
3. LTE = PTA
So I've just switched over from IPhone 4s > HTC One X > to now the Samsung Galaxy S3 (International unlocked version).
When I switched sims from iphone to one x, my data wouldnt work so they told me to get an LTE sim and give them the imei # of the ONE x. So i did that and everything was fine. They updated my account and i was receiving LTE on the phone with no issues.
NOW, with my galaxy, i just stuck the LTE sim in the phone and the phone defaulted to the cingular 410 apn. This is same as wap.cingular.
So here are my questions:
1. Would it be beneficial (from a performance/data speed standpoint) for me to call AT&T and tell them I'm back to a NON-LTE phone and have them change my account to a non-LTE account? And go through the process of changing my imei # in their system again also?
2. Since I'm actually on a smartphone unlimited (i did not take advantage of the $10/mo medianet) should I change my APN settings to "PHONE" and not use what the S3 defaulted me to?
3. Whats the actual difference in using wap vs phone APN's... I know the settings themselves are different, but anybody know the technical differences?
Thanks so much in advance!

T-mobile galaxy S3 on ATT 4G network
Hello can anyone post pics of the Galaxy S3 (T999) the t mobile version on ATT 3g or 4g networks. I am thinking about buying it but wanna be sure that it works before i spend the big bucks

This guy confirmed it works:
http://forum.xda-developers.com/showpost.php?p=27984139&postcount=28
Anyone else have such luck?

I'm having this exact problem. I have an unlocked T Mobile S3 that I want to use on the AT&T network. Phone, text and VM work fine although AT&T hasn't figured out how to give me data service in any form. They're all stumped by this.
What I really need help with is coaching AT&T through the process.

Does T-mobile GS3 work on ATT HSPA+?

Hi, im new, 2nd post (1st thread)
So heres some background info, I have AT&T but i work for t-mobile. Had my AT&T GS2 phone stolen by a t-mobile customer and the company I work for are great people and decided to replace my GS2 with a t-mobile gs3 for $100. They even offered me a dealer line to go with it (I get unlimited everything [NO THROTTLING] for $22 a month)
So heres my question. I know for sure that it wouldnt connect to AT&T LTE but for whatever reason if I decide to unlock and use it on my AT&T plan, does it have the proper bands required to connect to AT&T's HSPA+ network or would I be running edge?
I know all iphone's used on T-Mobile only run EDGE. (Coming later this fall they will be able to connect to t-mobile's 4g HSPA+ network)
Anybody have a clue?

I'm pretty sure it would work on atnt 3g speeds

It will work. The T999 has support for 1900 Mhz hspa+, which is the AT&T band.

Thanks. Much appreciated.

Confirmed working. I unlocked my T999. I have 2 sim cards, StraightTalk and Tmobile monthly 4G. I travel a lot, so depending on which carrier gives me the best signal that's what I would use. Usually, StraightTalk would give me the better signals...although Tmobile still gives me faster data speeds. just thought id share .02.

Hi, I'm waking up this thread as I have the T999 phone and recently switched to Straight Talk SIM (AT&T).
I only get EDGE on the phone using my Straight Talk SIM.
Is there anything I need to do with the phone? It runs the latest stock, not rooted or modified as such. It is carrier unlocked.

I unlocked my t999 and using it on my contract att plan, getting hspa+ atm, just check the bands that it supports, which are 850mhz 1900mhz for att's 3.5g(not 4g) LTE is 4G.

What apn settings do you use? I plugged my ATT sim into an unlocked SGH-T999 today with the ST APN settings and only get 3G. Speed isn't bad - 1164k down/1041 up, but I would like to tap into the HSPA+ if possible.

Testing Tmobile with unlocked S3

Hey All,
I've placed a Tmobile sim in my Att unlocked GS3. Ive seen many posts stating that the Att version wont get 4g on tmobile but 4g works fine for me; regularly I can get 5 to 10mb downloads. My issue though is that Im sometimes dropping from 4g to 2g/Edge then back to 4g. Should my phone be dropping to 3g instead ? Im quite shocked when it happens since I usually had strong 4g not far away at all.
Is the general consensus to to simply get a Tmobile device instead of bringing something from at&t? I really dont want to root the phone or flash roms at this point since Im just testing out the service.

You are in a refarmed market from the sound of it. The reason you go from 4g to EDGE is because the refarmed spectrum is most likely not through your entire coverage area.
T-Mobile uses the 1700 band, which at&t does not support, as their primary 4G deployment. This is why it is always recommended to get a T-Mobile S3.
That said, there is a firmware image for at&t's GS3 that unlocks T-Mobiles AWS band not just for 4G but for LTE as well. It is in the at&t forum - you will have to read the entire thread to get the relevant files and information on how to do it. Note that this CAN brick your phone permanently so only attempt it if you are willing to take that chance and you are familiar with download mode and ODIN.
The upside of using that hack is that the T-Mobile S3 doesn't support LTE at all.

Thanks for the clarification and info about the hack. Assuming I get a Tmobile device, should I expect to see a 3g icon instead or would it still say 4g?

It'll say 4g.. A 4g icon really means 3g/h+ and a 4g lte icon means lte

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.

H+ is LTE. Check the phone status >> mobile network type and you will see you are connected to fastest available network.

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.
