[Q] International HTC One X on AT&T US 3G problems

I'm running ARHD 5.1.0 on my international unlocked HTC One X.
I'm having a problem with my phone on AT&T. It is switching between H and 3G pretty often, and only H actually functions for data. This is pretty painful, especially when trying to stream Pandora.
I'm looking for help on how to analyse what is happening.
1. How can I see what band it is trying to use on 3G?
2. Is there a way to force it to always use H or EDGE, never 3G?
3. Is there a way to tune the 3G radio for AT&T USA?
4. Is it possible that now that the kernel source is released, the frequency issues can be fixed with kernel drivers?
According to Omega.net, here are the frequencies in my area:

}
Thanks!

Quick additional questions:
Is AT&T screwing with my signal? Would it make sense to modify the /system/build.prop to masquerade as a different phone?
Would modifying the /system/build.prop allow me to disable all but UTMS-II and UTMS-V?
ro.ril.imc.band=900,1800,1900,850
ro.ril.imc.uband="UMTS_BAND_I","UMTS_BAND_II","UMTS_BAND_V","UMTS_BAND_VIII"

I'm going to try disabling fast dormancy and see how that goes ala this thread:
http://forum.xda-developers.com/showthread.php?t=1111581

So far this change has had no effect. I still can't run speedtest.net for example, because it drops from H to 3G, then renegatiates to H again.
All I did was change the build.prop and reboot. Any idea if I have to do something more?

What APN are you using? the default one?
Mine changes to 3G, but only when not using data.......I've had this with every phone besides the Galaxy Nexus which stayed on H most of the time.
But I haven't tried streaming music, as I dont haha...I have it all on my phone.
Try using the Phone APN.
Create a new apn and type in phone for "Name" and phone for "APN" leave the rest blank and save, then click it to enable

You are the MAN! The APN was set to wap.cingular. Using phone as the APN I'm finally getting some Speedtest.net results! I'm going to do more tests, but this looks good so far.

I just tried all of that. When I delete apn and set up new one with just "phone" typed in I get no signal at all?

I made a new APN, in the name field I typed "phone" and in the APN field I typed "phone". Then saved, and selected it as the APN I wanted to use.

I did just that but it doesnt give me the option to select it after its saved....

I just received my one x from Singapore today and am not having any data issues. I picked the at&t network when I put the sim in and it just worked.

I spoke too soon. Speed tests were sort of working for me initially, but is working properly now after just blanking out the proxy and port lines on the default apn that it set up.

Removing the proxy and port seemed to get the same results as the phone APN.

Thanks for this, it solved my issue for my HOX too.

[Q] AT&T Ion (LT28a) Flashed with Hong Kong (LT28i) ftf issues

I have been a longtime XDA member in the X10 community, but have never before posted.
I purchased an Ion through AT&T the 24th of June, the day it launched, and after scouring the web, and XDA, I found the Hong Kong based ftf file from the link below and successfully flashed it to my phone.
Hong Kong based ftf, build 6.0.F.0.72, baseband 9x00B-SCAQCSZQ-34702060-04
http://forum.xda-developers.com/showthread.php?t=1711466
Maybe this was premature, as I am not sure how to make an ftf file, and therefore did not have my original AT&T ftf to revert to if this failed. (I would appreciate someone creating and sharing the original AT&T ftf for those who may need / want it.)
The firmware flashed successfully, and it is without all of the AT&T ware that can not be removed, and it also has a much nicer Xperia boot animation than the AT&T one, but I have noticed 2 issues with this firmware:
1. I did not back up or write down the APN or mobile network settings, and after flashing, the automatic internet settings feature in Settings, Xperia, Internet settings fails to find the AT&T network information. I did find some posts that have some AT&T APN settings (is that all that I need?) but I only occasionally get the 4G icon in the status bar when I was always there before flashing. Does this firmware possibly not utilize all of the available radio bands available on the LT28a phone as it is intended for the LT28i? Is there a hardware difference, or do I just need the correct APN settings? Can someone share these settings from the original AT&T firmware
2. Over the course of the last few days on this firmware, I have noticed that several friends have sent text messages that will show notifications on the lock screen, but as soon as I unlock the phone, I can't find the text messages anywhere. This does not happen for all people that try to send me texts, only some of them. I have tested with other people standing next to me, texting, we see it on the lock screen, then when I unlock the phone, no new messages to be found.
Can anyone provide the APN settings from AT&T for this phone, the original ftf files, and maybe provide some insight about the missing text messages?
Thanks!

It could be possible that version doesn't even support LTE? Since its international?

I knew I should have made the stock FTF before I configured everything and got it all setup. Maybe in the next day I will do it unless someone else does.

Hey mines still on the way, Ill do that first thing. If anybody needs anything else that an untouched stock unit can provide, leme know. eb

Cool that will work. Is there a wiki for the ion yet? we should get it setup with the list of stock FTF files.

Thanks for the screenshots Spectre51, I had the same settings though that I found on another post, the only difference was that "APN type" has "default, admin,fota,mms,supl,hipri,internet". I don't know that my results are really any different, but I will try with the settings you provided for a few days.
Thanks!
Earbrain, if you could make an ftf of the AT&T stock, I think it would be great. I think we should begin building a repository of firmware, basebands, etc, and keep it organized right from the beginning.
We already have the HK firmware so graciously donated by liuxueyuan1990, that I linked to in my first post. As soon as we have original AT&T, firmware to flash back to, maybe some other flash junkies will want to try it out as well.

How the internation firmware with all AT&T setting work? or do you have to flash back to original firmware?

Will do upon receipt. Should be tomor, mon at latest. eb

I don't even have the original firmware to flash back to yet. The international firmware is great., my biggest issue is that some text messages, from some people ( not all, not sure if it had to do with phone Contacts vs my gmail contacts) will show on the lock screen, but when the phone is unlocked, I can't find the text messages anywhere.
I also don't get the 4G icon in the status bar up top to often, it usually says 3G or H, but I think it really is 4G speed, it is much faster than what I have seen of 3G.
I prefer this firmware to the AT&T variant, it is more like a pure Sony firmware like you would see on an unlocked phone. Missing text messages are kind of a big deal, and I may want to switch back, wish we had root so I could just back up and restore easier.:-(

I'll post the att fw soon as pos. You should be able to restore via pc connect, just fyi. eb

Hey guys, got my ion in-hand. Wanted to backup firmware b4 doing anything for all our sake. Will flashtool work without screwing anything up?
Also, can't help but notice the missing curved screen. Anybody know what up? All pics even ones on the box show it curved but mine certainly ain't. Is that the case w you alls or did I just get fckd??? eb
Sent from my X10i using xda premium

I've only made the ftf after getting the two largest blob_f files from the sues folder. Don't even know how you would do it using just the software on the phone.
What do you mean by curved screen?

Loaded the international firmware on my LT28at and it works fine so far. Loaded the apn that I posted earlier and the wifi hotspot worked fine. Not in an LTE area though so I couldn't test that. I'm setting it all up now and will try using it for the next few days and see if I notice any issues.

I have a Xperia S bought this one because 4G (still waiting for deliver). Please test 4G if it's working. If it does I think should create a guide for flashing inter nation ROM, setting etc...

No MMS

Haven't been able to get an answer on the thread. I'm running MIUI V5 and it runs great except that the MMS doesn't work. My 3g data works fine , I just can't send or receive MMS. Is there anything I can do about this? I'm running on PagePlus (CDMA) with no sim.

ive flashed this rom before on my dinc2 and i had the same problem. the way to fix it is go to the google play store and download apn setting shortcut. to use the shortcut ull need to instal another launcher. holo or adw will work fine its just temp. then add the shortcut to the screen then open it. set up ur apn settings the name is VERIZON. apn is internet. the mmsc is www.mms.vtext.com/servlets/mms once you get that set up go into ur regular apn set and set the same thing to that one but leave everything else as is, then save. then reboot your phone. after that your mms should work. its a long process but its the only thing i got to work. hope it works for you.

I well definitely try this! Thanks

Hmm try creatong a new apn in ur regular apn settings along with the other and see if that works. If not maybe try reflashing.

The only way I was able to get it to work, was to disable MMS.apk through titanium, And set up the APN through GOSMS, but then I could only send, not receive. I wouldn't receive a text at all that had a picture.

Hey if u start having problems with go sms i figured out exactly what i did to get mms working in the regular text messages. When innapn settings shortcut go down to mms at the bottomwhere it says test and set the apn settings in it the same as the regular apn settings and then go down to proxy server in both of them and leave it blank then make sure u save both then do a reboot and ur mms should workjust fine. I went ahead and switched back to it and got it set up the way i like it. I realized i was missing miui style and ios7 style but dont wanna pay all that money for an iphone lol plus nothing beats the custimizations of android. Hope this helps this time. Worked for me buddy.

International Roaming with the G3

There is a pretty big bug with the new G3 that breaks international data roaming. This means your free international data will not work unless you follow the instructions below.
Before you leave the country with your G3, you must add a new APN that you need to use while abroad. If you try to roam with the built-in APN, you will get NO data.
Create a new APN and use the following values:
Code:
Name: Roaming APN (or whatever you want)
APN: epc.tmobile.com (no dash)
MMSC: http://mms.msg.eng.tmobile.com/mms/wapenc
APN Type: default,supl,mms
APN Protocol: IPV4
You can leave everything else empty or with the default values.
When you reach your destination (or before you leave), activate the new APN by making sure the bullet point is selected. To avoid issues, you should also change your Network Mode to "GSM/WCDMA Auto".
When you return, make sure you switch your Network Mode back to "GSM/WCDMA/LTE Auto" and activate the built-in "T-Mobile LTE" APN.
If you don't have data while in the US, make sure the epc.tmobile.com APN is not selected while GSM/WCDMA/LTE Auto is enabled. This combination will leave you WITHOUT data in the US. Using fast.tmobile.com as the APN and configured as IPV4 only will also leave you without data.

I think it's better to keep this separate and make it a sticky. It's clearer for anyone looking for help on why their international data isn't working.
I hope the mods will agree.

Cannot edit Samsung S9 APN type to add DUN

Can someone help me understand what is happening.
I have a unlocked Samsung S9 LTE phone with Freedom Mobile in Canada.
i cannot edit my APN Type it just gives me 6 options to choose from.
i want to add DUN to the APN Type but there is no text box to do this.
Someone told me to download ShortCut Master Lite and this can be done.
So i did.
it has all the options but doesn't contain the option com.test.LTEfunctionality
I don't get this and why this is happening.
if someone can shed some light here would be great.

Are you sure it doesn't have that setting? Look again closely because it should. As for the APN change I can't find myself in the app, you can do that yourself. Just add a new APN with a different name, duplicating all the settings except one where it says APN type. On that one make it default,mms,DUN Then save the new APN and select it.
Also under MOBILE HOTSPOT AND TETHERING, do you have Mobile Hotspot and Bluetooth tethering enabled?

i understand exactly what to do because i have done it with my previous Samsung phone.
But with this Unlocked Samsung S9 LTE phone there is no option to add new APN type, you must choose from the options.
See my attached picture.

It beats me. I've pretty much played with the APN on a ton of phones and never seen that dropdown instead of a text box. Maybe that has something to do with that setting not showing up in the app. I guess it's an international version of the S9 and I've never owned anything but US version phones so maybe that's a setting particular to those models.

Could this be the reason? 50 day limit?

i have no idea.
i thought my phone was locked so i paid for a service to unlock it.
they come back to me after 2 days and tell me that my phone is already unlocked, so to confirm i put a friends SIM card from another provided and boom, calls are made and confirms my phone is 100% unlocked.
someone must know why this is happening so annoying i just need my phone to be free to do whatever i want.
Anyone ? understand this.
