[Q] gt-i9100 US 4g access - Galaxy S II Q&A, Help & Troubleshooting

I have been around the forum for many years now, but am new to Android. I purchased a GT-i9100 in India for work travel between US and there. I have rooted and upgraded to 2.3.4, and applied a new kernel to remove the exclamation point. So, with that said, here is my question:
I am in the US right now, and in an area supported by T Mobile HSPA, but the phone will only connect to Edge. I am PRETTY sure it was only connecting to Edge before I did the work, but I cannot be sure. Would there be anything I did to the phone that would prevent it from getting onto the "4G" network? Is there anything I need to do now to change so it can connect?
I am not sure if this is related either, but I have a Verizon LTE data card, and if I place that SIM in the GT-i9100, it won't recognize it at all. It seems to only see T Mobile and ATT in the US.
I have spoken to T Mobile and they confirmed the 4g availability where I am, and they also reset my network connection, so the issue does not appear to be on my account or with TMobile.
Sorry for the long post, but I have been searching around and can't seem to get my small mind around resolution.

The SGS2 does not work with T-Mobile's 4G bands here in the US. If you want 4G you'll need AT&T.

That's because there is no resolution. As stated in several other threads on these forums (learn to do a search, and there's even one on the main page of Q/A right now) THERE IS NO WAY to get 3G on T-Mobile. The hardware in the phone does not support their 1700MHZ band.
Your 2 options:
1. Buy a T-Mobile phone
2. Switch to AT&T

[Q] Data not working with unlocked Aria on tmobile

I recently unlocked my HTC Aria (Att) and am using it on T-Mobile but it will not connect to the data network i can text and call but not access the internet from tmobiles network. I have been trying to figure out how to make it connect and don't know what to do. I tried setting it up to a new VPN but i don't know if i did it correctly. I am aware that it will only be an edge connection but something is better than nothing. Is there anyone that could help me out?

If you were trying to set up a VPN, that is the wrong option. You need to set up APN settings for T-Mobile. I'm sure if you search you will find the correct settings you need.
So an unlocked Aria's data will work with T-mobile?
Will an unlocked T-mobile device function fully with my AT&T sim card?

Yes to both questions. That's what unlocked means.
The only thing that won't work is 3G data because AT&T and T-Mobile use different frequencies for 3G.
2G data will work fine.

The answer is Yes and No. If your term 'fully' includes 3G data access then no in both cases you will not get 3G data speed. You will only be able to get Edge data, which is pretty slow. So if you need voice and text service and don't mind slow data speeds then go ahead.
Thanks. Well I actually have the problem that I don't get 3G on my Aria for whatever reason .-. Even though I emailed them and they said I should be able to get 3G all I have ever gotten is EDGE. l:
I asked this because I was looking at getting the new Sidekick, but I am seeing if it would be better to just go ahead and switch to T-Mobile, or staying with AT&T and buying an unlocked Sidekick.

Does your Aria have the AT&T logo on the top right? Also, check the model number underneath the battery. If it says A6366 then it should support AT&T 3G frequencies. If it says A6380 then it won't.
How old is your SIM card? You may need a newer one.

I already made a thread for this and couldn't figure out what was wrong, but what was weird was that like 30 mins ago I disconnected from my wifi because I moved my router and stuff, and I was getting G not E, but now that I did it again I am only getting E /:
That was the first time I saw I was getting G
And yes it's an AT&T one, it hasn't been too long since i've had it.
And the under the battery it says A6366

I suspect the "G" you were seeing was for gprs, which if I am not mistaken is slower than edge. Somebody jump in and correct me if I am wrong. If you are running a stock rom, you would see a "3G" not just a "G" if you were actually getting 3G data connection.

G is slower than E. It happens sometimes just because of the nature of wireless networks. Nothing to worry about. When you are getting 3G signal it will say "3G" or "H".
You should really do two things -- first make sure your area actually has 3G. Go to the coverage viewer on AT&T's website, click on "Data" at the top, then see if your area has dark blue ("Mobile Broadband" is what they call 3G on that page). Of course the other way to know is if you have any other AT&T phone that can get 3G signal at your location -- or perhaps a friend's phone.
If you are sure your area actually has 3G coverage, then I'd try going to an AT&T store and asking to switch to a new SIM card. Just explain that you can't get 3G signal on your phone and they should do it for free if the SIM card is old.
Good luck.

[Q] can i use Atrix in the philippines?

can i use an unlocked at&t atrix in the philippines?
and can it be upgraded to GB in the philippines?
im new here.. tnx..
Yes, it will makes calls.
No, 3G will not work. Edge however, should.
Yes, you will be able to update it manually using motorola's update guide.

thanks man! appreciate it.. i know that the atrix have quadband for gsm which supports 900/1800 here in the phils and for the 3G, the band here is 2100, why it wont work? ... and other than updating manually, can i update it via wi-fi?
The 2100 band is the problem. AT&T Atrix doesn't support that band.
I don't think the OTA works using wifi but you can download the stock update using wifi and apply it.
CORRECTION: it does support the 2100 3G frequency. I didn't understand the whole WCDMA vs GSM thing correctly
i have read some old reviews when it is still in Froyo and there are a lot of complaints about the laggy pinch to zoom of Atrix.. how is the pinch to zoom of pictures in Atrix GB?
I have not experienced any problems. The zoom is very responsive
well i just hope someone who bought an unlocked at&t Atrix from the US and used it here in the Philippines would post their experience about the phone. i have read from different sites and forums that they have complaints about Atrix connectivity like wi-fi and bluetooth in different countries.
it's just too bad only few people here in the Philippines use Atrix.
I used my phone in the philippines. I was able to get internet on it. Not sure it was 3g but it was the h+ symbol on both smart and globe. I went to their offices to help set it up. Just remember, most places won't have 3g yet especially those place that don't support smartbro or globe broadband which uses the 3g signal I believe. Just ask for help there.

Wi-Fi and Bluetooth use the same standards around the world. I wouldn't pay too much attention to those complaints.
The issue with GSM coverage is that the phone must support the frequency bands for the local carrier's equipment, and the carrier must support the specific GSM standards (GPRS, EDGE, UMTS, HSUPA, LTE, etc.) that the phone is capable of. The Atrix 4G does indeed support 2100 MHz but as other folks have noted in this thread, the main carriers in the Phils (Smart and Globe) don't support HSPA+.

im quite confused about that 3G thing.. your post was right.. Philippines do not belong to the list of HSUPA networks.. but when I viewed the list of HSDPA networks, Philippines was there.. (i could not share the link for the meantime, 3 more posts needed).. this got me really confused.. im afraid i cannot use internet services by ISP.. maybe wi-fi only..
thank you guys for helping.. i really appreciate it.

I'd be interested to see your link, but if it came from the same site as the one where folks think that wi-fi and BT won't work in the Phils. then again, I wouldn't put much stock in that claim. HSPA upgrades aren't cheap and with 1 Peso per minute calling plans I don't think the carriers there have much of an upgrade budget. (My wife is a Filipina and has had GSM phones here in the states ever since AT&T has been selling them.)

No problem with the questions.
I don't recall if my Atrix had an option for SMS delivery reports prior to me applying the OTA update to GB. I don't see that option now, but maybe I'm looking in the wrong place. In any event that sounds like a feature of the Android OS (if it actually exists). So if it's lacking (or present ) on other Android phones then I would expect the same for the Atrix.
thanks andy for the informative replies. Im quite relieved now after i have read the previous post by mamoranto.
because i have have had 5 GSM phones from the states which came from different carriers and i have no idea on their specific details (because mostly are gifts), out of the 5 phones only 2 phones are used for "all around, daily purposes" because here in the philippines, texting is the number purpose of a phone. does the Atrix have sent items/messages stored after you send an sms?
sorry for my noobish questions.

Well I stand corrected.
The "Globe Telecom" page on Wikipedia claims both 3G and HSDPA support on their networks. Apparently they've just begun rolling out WiMAX in Metro Manila and points south as well. This page reads like marketing copy, so I assume this info comes straight from Globe.
Dang...wish I was in the Philippines again!
oooppss sorry for the previous post... it was answered.

I think *every* phone in the Phils originally came from the states, LOL. Or at least that's the way with my wife's family. My sis-in-law just got my daughter's barely-used iPhone 3Gs, and my niece there just got my wife's BlackBerry Curve (wife and daughter had to get new iPhone 4).
Are you gonna buy this Atrix new there? You must be rich...
P.S. The Atrix does keep copies of sent and received SMS messages. It shows them in threads/conversations like iPhone, or Chikka.
It uses the Text Messaging app which I think is part of the Android OS. Motorola also throws in their own messaging widget if you want you want to use that.
My dinner break is over and I need to quit this thread for now...
Mabuhay!

[Q] Late bloomer--can't understand lack of 3G

I recently bought an unlocked SGS3 GT-I9300 in amber brown. This is my first smartphone and I'm just learning there are many variants of each model. I bought a Net10 sim card labeled to include 3G & 4GLTE but now I understand my phone isn't 4G capable. That doesn't bother me but what does is as I'm commuting daily through a fully-saturated 3G area I never see 3G on my phone. If I watch it closely as I drive (not a good idea...) I have seen it flicker for a split second a few times. I've called Net10 customer "service" and was guided through the entire configuration a 2nd time but it's still the same. They had no further suggestions.
I like everything about the phone and can't complain about the performance. I get 3-5Mbps download speeds on H+ (whatever that is) and web pages load fast. One of my main desires is to stream internet radio through the phone to my car radio and I'm concerned the limited speed might give me trouble with keeping connected to a station.
How do I find the cause of the limited speeds? At this point I don't know if the issue is with the phone, the sim or Net10. I'm open to switching carriers as long as I stay on GSM. I have a cottage in northern MI where GSM is strong but CDMA is almost non-existent. I stopped at an AT&T store yesterday hoping they might be some help since it's their network Net10 buys time on--but the 2 kids there were clueless.
Keep any suggestions simple, I'm a noob and old--a bad combo
I'd suggest you try Wikipedia for an explanation of mobile data, H+ is 3G and the best you are going to get without a 4G capable phone.
Also, the i9300 isn't sold in the USA so you probably have a variant which has a specific forum here on xda -as our files will brick your phone. Check under the battery for your actual model number.

Thanks for taking the time to reply to my noob questions. I have been searching the net for info. The wiki S3 page was helpful, but I didn't find a mobile data page. Does the US version have the H and H+ status indicators? If not then I can understand why I never found an explanation and why the folks at the AT&T store didn't know either. That really doesn't excuse Net10 CSRs not knowing--especially since they are all "international".
Regarding the I9300 thing--do you mean there is a sub-forum for international I9300 phones? I thought I had found the right spot...?
My phone came from a guy in Alaska and it still has their (GCI) oem software on it. Does that mean it's already been reloaded with local OS? My Device Status is "Modified" but I have no idea to what extent.
Also--if "H" = HSDPA and "H+" = HSPA+ is my phone fully compatible with US 3G and what kind of real-world speeds should I be seeing?
I'm heading up to my cottage after work today and will be testing the phone there. If I can't get data there I will be discarding Net10, and possibly this phone. On Verizon I could not talk and texts took a long time to get through. I bought a cheap flip phone on Tracfone for use there & it gets pretty good signal.
The i9300 isn't sold in the USA for good reason, as it won't get the best out of the networks. It will work, as you've found, but how well I have no idea.
I'd suggest, again, that you check the actual model number printed under the battery.

This is the I9300 page .
But as said really we are clueless about use of the international model used your country .
Basics are any firmware and a modem to suit your local network .
As said you are on 3G already .
H+ is actually 3.5G, etc, just Google it, all explained somewhere in a wiki for example http://readwrite.com/2010/09/16/3g_35g_4g_lte_wimax_beyond_the_marketing_speak#awesm=~opViZD2o1WYsB0
Sent from my Nexus 7 (2013)
There have been one or two users who use the phone in NA .
Been looking at some "how fast are you" posts here and it looks like I am getting pretty typical speeds.
I guess it's working as it should.

[Q] No LTE option in Network settings?

Hi folks,
I've got an unlocked HTC One Max which I bought SIM free from Amazon UK. I'm using Three as my network provider in the UK and they've begun rolling out 4G to Glasgow where I live. One of my colleagues is also on Three with a Samsung Galaxy S4 and he started picking up a 4G signal this morning in the office whereas I'm still only seeing 3G. We had a poke around on our respective phones and in the Mobile Network Settings under Network Mode he's got more options than I do, including one for LTE. I've only got two options: WCDMA only and GSM/WCDMA auto. Without being able to select an LTE option in here I don't see how I'm ever going to pick up a 4G signal. Does anyone know why I'm seeing no LTE option in here and how I go about sorting that?
Okay, so I did a live chat with an HTC rep who confirmed that if there's not LTE option available in the settings then I've got the 3G only variant of the handset. I've no idea why HTC would even sell a 3G variant in the UK as it makes no sense at all, but I looked on Amazon and they only sell a single variant of the phone (which is definitely the one I bought) and curiously the listing for it doesn't clarify either way which network protocols it supports. I even tried Googling the product number (99HWN005-00) but I can't find any solid information about which version of the phone that represents. I'm hoping here that it's just a mistake and I should've been sent the proper 4G variant but it's impossible to say for sure when the Amazon listing gives no info at all about what they think they're actually selling. Either way I'll still be trying to get Amazon to take some amount of responsibility here because I think I made a fair assumption that I'd be buying the 'proper' version of the phone from them; especially as there's nothing on their site to tell me otherwise. I suppose it'll be down to how seriously Amazon take customer service as to how far I get with them. God damn it!
Grrrr. So I did another live chat with HTC to try and find out more about which models they sell in the UK. The Amazon listing has a model number and I was hoping HTC would tell me that's the model number for the LTE variant so I could go back to Amazon to say they'd mis-sold me the wrong version. This time though I got a different story; the HTC rep told me my handset is definitely LTE capable and what options you see for networking are tied to what the SIM card is capable of. His assertion was that Three had given me a 3G only SIM card and getting that sorted would fix it.
However, I swapped SIM card with my colleague who's getting a 4G signal from Three and it made no difference on my handset; I still only got the same 3G network options and, of course, only got a 3G signal. It also occurs to me that I checked with another colleague this morning who's got an HTC One but only on a 3G contract with O2 and he's already got the LTE network options (although he only ever gets a 3G signal of course).
So, yeah, this second call to HTC was a load of nonsense. Excellent. Back for a third time I go...

Perhaps the variant you purchased does not support the lte bands that your carrier is using. That's usually the difference between the variants....radio support.

Even if that was the case I would still need to see the option in the settings to turn on LTE; I don't even have that option so regardless what bands my carrier is using my phone wouldn't pick up a 4G signal of any kind.
I've basically somehow ended up with a 3G only variant of the phone which frankly they shouldn't even be selling because there's no point. I might ping HTC again with a more direct question but they don't seem to be able to tell me what I've got so it's more likely I'll just go back to Amazon and see what they have to say about it.
Also I did a quick check and Three are using the 800 MHz band which the 4G version of the HTC One definitely supports.
Okay, so, I sort of got it fixed but it's a really stupid situation. There's a key code to get into a hidden setting menu on Android (*#*#4636#*#*) which bypasses the normal options and allows you to force the network mode to any of the ones Android itself supports; so it's got all sorts of weird **** like EVDO and whatever in there. I went in there and forced on 'LTE only' mode and now I can pick up 4G if I stand in certain parts of the office. I've put it to 'GSM/WCDMA/LTE auto' and it should now go up to 4G whenever it gets a strong enough signal and work as it should. Why I've had to do that hack to get it working, and why the normal user level UI doesn't expose the LTE related options, is a ****ing mystery though. With KitKat rolling out that might might sort it but I shouldn't need an OS update to expose functionality the hardware's already capable of. It's really ****ing stupid all in and not doing HTC's rep any favours with me as I'll probably have to repeat the same stupid hack every time I reboot the phone.

[Q] How do I get this to work with AT&T [/Q]

I read a few threads and am confused, so I thought I would just ask. I have a few 4G LTE devices for Verizon and am ready to switch to AT&T. Let's just say that Verizon and I had an argument and it is time to switch. Plus I would be saving over $50 to switch to AT&T with a month to month with a BYOP plan.
I visited the AT&T store today and had them insert a SIM into my S4. I get the error "This SIM card is from an unknown source" in the banner. I get a signal strength and a H for where the data symbol 4GLTE is. Then it drops the signal and refuses to have a data connection. At this time the APN settings were NOT adjusted. This was a straight out of the box S4 rooted on NC5 with Android version 4.4.2. After messing with the S4 for awhile he moved to the S3 and entered the proper APN settings. It pulled data, but only at EDGE speeds or 1X. Also, my last device, a Samsung Galaxy Tab 2, has no way of editing the APN settings. It is NOT rooted and is still on stock firmware.
My questions are these:
1. Can this be done?
2. What do I need to do to the phone(s)/tablet to make it work?
3. Will I be able to get 4G speeds?
I do not want to purchase phones with AT&T today because I just don't have the money. I already have these devices, I just want to swap them over. I am comfortable with flashing using ODIN and even so far as using safe-strap. I have flashed some custom roms, but my phone is a daily grind phone and I really want something that works 90% of the time.
Thanks in advance for any help!

None of the codes work either:

It was an answer to this same question asked by you. This thread is redundant.

That thread just asks if the SIM card would work and if they would need to flash a GSM ROM to their S4. That thread does not answer the questions I asked. I just gave my insight after a visit with the AT&T store. Store techs tend to not know as much as the XDA community. That is why I asked here. So no, it is not a redundant thread. I appreciate your answer, but it isn't what I am looking for. Not a straight up yes or no, this or that.
As for the GSM locks I discussed, it was from an experience I had with a Motorola Droid 2 and using it on a local GSM provider in the USA. So yes, that was pre LTE.

My point, which you apparently missed, is that there is no reason for starting up yet another thread to ask questions that have already been answered. That''s why I said that this is redundant.
OK, let me answer your questions.
1. Can this be done?
Yes, you can install an AT&T SIM, set up the APN, and it will work. What bands you get and what bandwidth you get depends on what bands AT&T are using in your area. You won't likely be able to get LTE speed; most likely just Edge. You can't fix that, as it's a limitation of the phone's radio hardware. Again, some people have made claims that you can flash the AT&T GS4 modem on a Verizon phone and change that, but that's pretty risky as it will likely brick your phone.
2. What do I need to do to the phone(s)/tablet to make it work?
It works, for some level of "work". If you're stock,some people have reported that the firmware requires CDMA for some functions, like SMS. I haven't verified that. I was able to send SMS with my phone and a UK SIM which uses the AT&T network.
3. Will I be able to get 4G speeds?
Not likely. For example, see here http://phandroid.com/2012/12/10/nexus-4-att-lte/ - the common band, LTE Band 4, has limited AT&T coverage.
I haven't gone over the specs of the two phones lately to match them up, so that may be worth looking at again.

Thank you for your answer. I decided to trade the phones into AT&T and get a credit towards a Samsung S4 and a Asus Padphone X. After I read a few more posts over the internet and a few more hours figuring out how LTE works I came across the answer. I did miss what you meant and I apologize. Again, thank you for your answer.
