Just switched from XSG to XSA. Although there is the SimManager for dual, it appears the support for dual sim is still different. I was able to get 4G+3G on XSG but not XSA. It was briefly possible when I first logged into my phone with XSA but was set to wrong priority. When I tried to switch, the function is gone. Anybody know how to force enable it?
Update: Figured out using 4G Switcher (called 4G LTE Switch in Playstore before install).
FYI who's also interested. Set SIM 2 to what ever you want and use the app to set SIM 1 to what you want. It can't modify SIM 2 settings. It appears I can't set both to 4G though someone can. But after setting in 4G Switcher, you can change data connecting back to SIM 1 and select keep current setting instead of changing to 4G preferred or it will automatically set SIM 2 to 2G only again.

Hi,
I am unable to use 3G on htc desire. I have set the correct APN. The problem is that when I choose "WCDMA" as the network mode, it automatically switches back to "GSM only". The place where I live has no problem with 3G availability. I feel the problem lies more with my handset. Can someone please help ? Is there anything that I can do to get rid of this problem. My phone has lost its warranty since I unlocked it.
Have you tried any other operator sim card? It's a good troubleshooting to do when this kind of problems happen...
Had problems like that before and it was an incorrect APN setup.
Thanks for getting back. I tried with a different sim and a different operator. They were also not successful. APN setting is perfectly right for the current sim. The APN settings were given by the operator.

Are you using any kind of widget to switch APN on / off, 2G/3g ?... I noticed that for example, Widgetsoid can mess with 3g connection so much that sometimes you need to remove it and reboot the phone so you can get things working again.
Try using another SIM card too. It may give you a clue on what's going on: wrong settings / card with no data activated / etc ...
I am not using any widget to turn on/off the 3g. EDGE services work on my mobile while 3G is not working. If I use the sim card on to a different mobile, 3G works fine without any problem. Tried using another sim card with 3G data activated and that also did not work fine for me on HTC Desire.
I just got the core. I added the correct APN settings, but for some reason this phone only connects to edge. Is there a setting I am missing somewhere?
I am on straight talk, AT&T compatible sim card.
Phone is unlocked.
Any help is appreciated.
You possible don't have 3G selected to use for the simcard you can only use 3G on one simcard at the time in sim settings you can choose which one you want to use

So this is likely a settings problem rather than a hardware incompatibility?
Can this phone connect to the AT&T HSPA 850/1900mhz band? or do I need a sim card compatible with the 900/2100mhz band to get HSPA connection?
I looked in the sim card manager but I don't see a setting to enable 3g, only to select which sim's data connection to use. I currently only have one sim in the phone. I may get a 900/2100mhz compatible sim and see if that works.
in a related note, how to I bring up the debug/settings menu from the dialer? its usually *#7268#* or something along those lines but I can't find the specific code for this phone. I have a feeling changing some of those settings may help.
Go to settings/wireless & networks/more settings/mobile networks/(Then depending on the sim you use for data)Network mode/WCDMA only and you are done.

It won't let me select WCDMA only. When I do it goes back to the previous choice automatically.
Hello all.
I bought a Galaxy Core from the Middle East(2 Sim cards) and tried to use it in America through Strait Talk. The phone is working fine and the only problem I have that I can not get 3G just E (EDGE) which is so slow. I put my Sim Card in a Galaxy S III to make sure that the Carrier provides 3G. As soon as I put the Sim Card in Galaxy S III, I immediately got H +. But when I put it back in my Galaxy Core I got E.
My area covers 3G
APN setting is according to Straight Talk instructions
Any idea why ?
I would highly appreciate your answer and help!!
Check network mode - maybe it is set to use only 2G. You can find it under Settings -> More settings -> Mobile Data

Mode is already set to GSM/WCDMA (Auto Mode). I can use this option and GSM Only option. I can not use WCDMA Only option. If I chose WCDMA Only, I will loose the the whole mobile service. Thanks a lot for your help and time.

Look You can't use 3G on both SIM at the same time. So choose WCDMA only on the SIM you want to use 3G and use WCDMA/GSM on other SIM and this might not be allowing you to choose "WCDMA only" so better check 2nd SIM connection type.
and yup it is common that network disconnects while change the mode of connection. It will be stable after your option is set.

In fact I am using only one Sim Card. I chose WCDMA Only and restarted the phone. I lost the service again. Thank you Bro.
I too have an issue with my Samsung Galaxy Core prime sm-g360t, my 3g is not working n I've tried LTE/Wcdma/gsm, buh it's still not working
actually ..our galaxy core now became as trash ...even i faced the same problem but there was no fix except an workaround ...the thing is lots of companies has put many features in their "new" SIMs and galaxy core is unable to process those(hardware problem) but if you use an old sim like 2-3 yrs old it will work for you ...after many many googling i had nothing in my hands but solved it by using my old sim ....just take someone's which is old and see if it helps ....
----by an same problem facer
Got the L29, so dual sim.
My first sim is for calling and sms, so I only need 2G but I can not set it to only 2G. Just the sim for mobile network (it's sim 2) can set to 2G, 2G/3G, 2G/3G/4G and only 4G.
The problem is 3G is really bad for sim 1 and this drain my battery for nothing, cuz I only need 2G for calling/sms.
I got a lot dual sim devices and this one is just strange in some things.
Regards
This is a problem for me, too
Dosen't work, I call already Huwei and they can not help me. Really bad :/
theres a setting in sim card management under mobile networks. it lets you pick which one gets data.
I can easily set 2G only for sim1 here, dont know what you did? Or your carrier doesnt support this, I mean if there is no 2G in your country, why could you change it to 2G?
Same problem on my mate 9 and my axon 7, seems to be an androidwide problem.

Naw, it works perfect with OnePlus 3, 3T, Mi5, Mi5s, Mi5s Plus and all other phones. Set Sim 2 to 2G/3G/4G and Sim 1 only on 2G. Here you can set Internet and this is it, the other sim go 2G/3G.

In "settings/more/mobile networks" I can set the preferred network mode for each sim card. Had this when I used it as dual SIM for my work: sim 1 data mode on 2g, sim 2 on 4g. Works perfectly, even on 2 completely different providers.

I don't believe. When mobile data is default set to sim 1, just to sim 1 can be selected preffered network mode.
In my case: sim 2 -default mobile data- can be set to 2g only/auto 2g3g...evrything. Sim 1 switched automatically to 2g/3g/lte auto-can not be set preffered network mode.
If i switch default mobile data to sim 1, preffered network mode can be modified in sim 1, but not for sim 2, and sim 2 switched auto to 2g/3g/lte auto.
I want like this:
1. sim1 default data-3g/4g/lte
2. sim 2---2g only. But this is not possible because just in this case, sim 2 jump into 2g/3g auto.

Nope... Just the sim which is for mobile network. If I change sim 1 to mobile network, I can set to only 2G but the other one will be 2G/3G

Ah I see what you mean! Have been playing with 3 different dual SIM phones last year so got it mixed up. What I did with my Huawei mate 9 when I used dual SIM was: sim 1 set to auto 4g 3g 2g and on sim 2 I overruled the automatic provider search and just picked the 2g network from my provider. It then still mentioned 2g 3g in dual SIM settings but it didn't connect to 3g because I selected a 2g only network.
Is this how you want it?
on my ZTE it's really funny. the setting is available but disabled lol
Fixed By using Tasker [No Root]
I got this issue fixed by using Tasker so probably there might be an ADB command to set the network mode
My fix:
Make a new task -> Press + button -> Mobile Network Type -> Choose required network mode
Note: Will need to enable USB debugging and use the command `adb tcpip 5555` for getting the permissions. Also this might need to be done after ever phone reboot
I have a US unlocked S22 ultra with ATT and it seems I don't have the network mode option available.
I can not select 5G or LTE. I can download an app and I can set it up using the app but it is not in the main menu officially.
Do you have it with or without ATT sim card.
I think Samsung disables that option using the CSC but there is a change ATT disables that using the sim profiling
It was taken out with the last update. If you download Samsung Band selection app, you can go into more network settings and change it from 5g to LTE there.
What's the reasoning for removing that option? Can't think of any

This doesn't work either. You get an error when you tap the Launch Band Selection button.
Works fine to me on latest July Update AT&T.
