[Q] AT&T One X in India (3G)

Hi all,
i have an unlocked at&t one x. i'm using it in india on vodafone network. i wanted to know if 3g will work on this phone? i see the E symbol on the notification bar. does that mean that it will work only on edge? the frequency bands seem to be compatible. is there anyone who is already using it on the same network and can help me out with this? thanks.

Did 3G ever worked for you ? How did you unlock you AT&T one x, sung unlock code ?

If you go to your dialer and type in *#*#4636#*#* , you will go into testing mode - where you can check your network settings. Verify that your network is not set to something like "LTE Only" (which is not available in India).
Preferably set it to "WCDMA Preferred" or "WCDMA Only" (You can also play around with HSPA ).
See if that works.

this should be in Q&A section.
Are you having any 3G plan from vodafone? - If you are on 3g plan you should get 3g automatically.
-Try changing network modes if you have a 3g plan but still get edge only

Having the same problem..
I have an AT&T Unlocked HTC ONE XL (Eviita)
Its Bands seem to be compatible with 3G Bands in India.
I have tried everything (*#*#4636#*#*) and tried all banks.. on "WCDMA PREFERRED" it still shows "E" and my sim comes 3G data plan is active.
I have Unlocked Bootloader, S-Off, Rooted, Installed Cynganemod 10.2 (Android 4.3) with G-apps and its all working fine, but still no 3G.
Any help on this from anyone.
Theres only 1 thing i can now think of... when u go into (*#*#4636#*#*) mode and click on Phone Information and scroll down, u can see one tab which cannot be clicked and it dimmed out, it says... "OEM-specific Info/Settings", but you cant click it.
Is this a Data Locked phone?

When buying any phone from a source other than your carrier, you need to do the research on band compatibility BEFORE you buy the phone. As this is set in hardware, and is can't be modified. The fact you say "seems to be compatible" implies that you aren't sure.
Also, you haven't mentioned what carrier you are using. The OP says Vodaphone, and I can't find any info on what MHz band Vodaphone uses for 3G. You need to know what band your carrier is using for 3G. Your carrier needs to be using one of the bands 850, 1900, or 2100 MHz for 3G (HSPA). Otherwise you will not get 3G on this device.

That doesn't mean anything, did you make that up? Either the phone is SIM unlocked or not. There is no "lock" on the device that would make you get EDGE but not 3G. Getting EDGE but no 3G typically means that the device is not compatible with your carrier's 3G network.

I've reported the thread to mods for moving.

Thread moved to Q&A forum.

is your phone on 'gsm only' mode ? I've used the same phone in India but it wasn't a AT&T one though.

[Q] samsung galaxy ace plus and ace 2 only getting edge speed on t-mobile

hello,
i hope i put this in the correct forum area.
i have t-mobile as a carrier. i bought two new samsung galaxy ace phones. ace plus and an ace 2. both are the latin models, not the euro models, and have the 850/1900 3g freq, but when i use my tmobile sim, both phones are running on EDGE speed and not 3g. anybody know why and how to get them to run on the 3g, tmobile was a waste of time asking them, no help
thanks

U should enable it in settings>mobile networks. U can either put it on 3G, 2G, OR automatic (for the network to chose which is best)

you would think so, but in that area the only options are
network mode....
gsm/wcdma ( auto mode) which is selected
gsm only
wcdma only
and "network operator" , which i search, tmobile comes up and is selected
still on edge speed, i do not see anywhere to select 2g or 3g
any ideas???

You need to find out what lte bands your carrier uses. And make sure they are comptible with the sprint varients lte bands.

If what I've read is correct, Sprint Note 5s have the same hardware and radio band capability as the international version. So a hack or something should be possible. But how or what is way beyond me.

Just got a S8+ and found out it doesn't support my carrier's network band

Just got a S8+ from my brother and was having some troubles with it (can text/use data but not recieve/make calls) and found out that the cause was because the phone supported the 4G LTE band of my carrier but not the 3G band which is what my carrier uses for calls.
So how screwed am I? is there anything I can do to fix this?

Try in settings - connections - mobile networks and change network mode to 2g/3g or 3g mode and see if that works.
Note: I am still on nougat so settimgs location may be slightly different on oreo.

i've tried it and it didn't work as the specific model phone I have does not support the 3G band of my carrier (Freedom Mobile) so I can't connect to any of my carriers bands aside from the 4g LTE one

Is this your model
https://www.sammobile.com/devices/galaxy-s8-plus/specs/SM-G9550/
If so I would get in contact with your provider and see if is compatible with there network frequencies. apart from changing providers I am not sure what you can do.
If I've done my research properly freedom mobile is Canadian region apparently there are to modes home and away have you tried the away mode

yes that is my phone
i think away might actually work really well, how would i force it to only use away/roaming?
okay this is weird, so i turned roaming on, connected to a different carriers network (rogers) and i can text and data fine but still cannot make or recieve calls on a AWAY network....? does this mean it shouldn't be a network band problem?
it shouldnt be my sim card as my sim card works fine on my older phone fine (s7E) and i JUST got it replaced my the warranty service (to fix this problem, which it didnt). It shouldn't be the phone either as my brother put his sim back in the phone and he can make calls fine....... what is wrong here?
IT WORKED THANK YOU SO MUCH!!!
changing to rogers did not work (not sure why? maybe they use the same band is freedom)
however afterwards i changed to telus and i got calls!!

If you mean upgrade to Oreo I do have some minor issues at the moment nothing really major for me to worry about if I do upgrade. To save going way off topic here might be better to start a new thread or I could pm you if you like.

ATT and Mi Mix 3

Hello XDA community,
I have a Mi Mix 3 Palace Edition phone and I am using AT&T for my carrier. The phone came with a Chinese ROM but I flashed it with a Global one. I have been trying to get 4G + LTE to work on the phone but so for all I am able to get is 3G. I have contacted ATT and was told that my account was not setup for it. So ATT's advanced technical support made sure the IME/my account on the phone was LTE enabled. I am still stuck on 3G. I have selected the correct APN for it but I do not connect.
What am I missing?

Preferred network Type?

preferred network LTE.

Did you checked if your apn is correct?

Try selecting 4G network manually. I faced issue like that initially with ATT MVNO. After seleting 4G network manually I am geetting 4G+

In the Settings, go to About Phone, and tap the storage until it brings you to the SIM and WiFi screen. Tap on the Phone Information for the SIM you are using and set that Network Type to UMTS/LTE.
AT&T blocks any device you did not purchase directly through them from using VoLTE and WiFi Calling. 4G is also LTE, so if you see the 4G icon, that is also LTE and 4G+ is also LTE-A.
