Mobile data problems

Ok, Ive always had crappy 3g on my x10 but i put it down to signal issues, i thought i was in a poor 3g area.
I noticed whilst playing around in the settings that i could set the phone from WCDMA only, whereas before it was GSM with WCDMA preferred.
This sorted the problem out perfectly, great 3g performance even with crappy signal, the problem is that for some reason this means when there is no 3g signal it doesnt just fallback to GSM for voice.
From what i have read on the net it seems like changing to WCDMA only should -only- affect the data connection, not the phones voice connection.
Am i doing something wrong?
Is there a way that i can force the phone to use 3G only for data, but still use GSM for voice?
Thanks

in that case you should set the settings to like this 1. wireless controls 2. mobile network 3. network mode "WCDMA" then 4. network operator then search network tap the available current network what u r using do not select the automatically 5. done
after that turn off the phone remove the simcard for 5 sec. then turn on again wala u have 3 to 4 signals on ur 3g connection....

Thanks for the tip, it didnt work, but thanks

I have GSM/WCDMA selected but data unchecked and still works great

Anyone know what app can manage data and mms? I mean I don't want data connection but I still want mms enable.
Thanks

ouch, seriously doubt that's possible on the x10
maybe deleting the 3g APN or creating a blank one and just selecting the right mms one

Isn't MMS dependent on data?

It is but you can create 2 APNs one for data and one for MMS and after enable/disable the data APN on case by case needs
At least i think it works on rogers because i saw separate settings for MMS only.

I am confused too. Hohoho... But as I remember, previous phones (such as X1,X2,p990) did have this options. Correct me if I am wrong. Because I always connect internet/browsing using wifi. Except mms.

3g data connection lost

Hi guys
Today i want to do a speed test on edge ( 2g ) by switching network mode to gsm only .
After switching back to wcdma i no longer get 3g . I only get E for edge .
I have froyo tayutama superslim .
I switched to darky rom still same issue .
I tested my sim in another phone 3g worked.
I tested another sim in my phone i get no 3g.
What do i do to get 3g back ?

Hmm, one thing that always helps me if I have problems with apn is to go to wireless and networks- mobile networks - apn - reset to default.
Well, and there are full proof methods - data wipe, dalvik cashe wipe, cashe wipe, reflashing of firmware completely.

I had to manually input my provider's APN after installing Tayutama's rom:
Settings > Wireless and network > Mobile networks > Access Point Names
If you don't see your APNs there, you have to set them up manually. Check your provider's site for the neccessary information. Good luck.
PS: You shouldn't be posting this kind of request in the dev section. It belongs in the Q&A section

thanks for your help guys.
data WORKS but only on 2g which is EDGE but it doesn't work on 3g !
i already tried 2 different rogers apns.
and i already performed a data wipe, dalvik cashe wipe, cashe wipe, reflash of firmware completely.
and just to let u know an APN Can't control 2g or 3g.

Maybe you're over your provider's data limit for 3g then? Mine automatically switches me to 2g if I get over a certain volume.

Ah, didn't look at your provider. You might have problems with modems. As canada uses 850 band. Though you probably know that.
besides that - try setting not just gsm or wcdma in settings, but auto. I often have problems with switching them to just one setting. But auto always works.

Thanks for ur respond. I don't how to check if I lost 850. But my product code is set to the bell one. I really have bad connection now. It switch from 4 to 1 bar then to nothing then to gprs and so on

Did you manage to solve this? I am having the same issue and googling never turned up anything.
The only way I could force it back on to WCDMA 2100 bandwidth is using servicemode.
If I toggled GSM only it goes to GSM900. But I cannot get it back to 3G where my home has decent coverage. GSM900 has extremely bad coverage in my home but good elsewhere in my region. 3G isn't covered regionwide so I get missed calls and lost SMSes.

Yea i lost the 850 band. Try *#*#0011#*#* rgen go to network then band selection then input key 5 which should bring 850. If that doesnt work just search for doc rom

[Q] Question about 3G network (WCDMA)

Hi all,
I'm struggling to get data connection over the 3G network, even though I've got a data plan and the settings seem to be on point.
I'm based in Dubai and I've got a Middle East tab (garbage as the firmware excludes the Android Market), so I've flashed a recent Euro firmware (JIP was the build if I recall)
When I go into network settings to choose 2G/3G/Auto, it shows me GSM and WCDMA as the choices. I'm pretty sure before the flash, it showed GSM and WCDMA. Is WCDMA the same as HSDPA?
The problem could be with the carrier, but I'm troubleshooting at the moment and this WCDMA is a bit confusing.
Any insights would be greatly appreciated. Thanks.

Have you checked your APN settings? Chances are that the Euro firmware doesn't have the APNs "pre-installed" for your carrier(s). The good news is that you can add them in manually if this is the case.
Regards,
Dave

If your display shows a 3G or H type signal, then your problem is a bad APN setting.
WCDMA is 3G and H on your display, if you have that then you're in good shape.
Search the net or the carriers website for the the correct setting, then create a new APN and data will instantly start to flow.

It was missing the apn setting. Justed typed it in manually and Im hooked up. Although i was bamboozled for a little while as the H didnt apear until i had turned off the wifi.
Thanks for all ur help guys.

[Q] SM-G900i with ATT network

I got an international version SM-G900i from Amazon. I have an ATT sim card. The text and phone calls work fine but I could not get any data roaming. Though from other posts I got the data roaming, I was not able to set onto the ATT 3G/2G network in the network operator selection. My network is always shown as Maritime. Does anybody know why this happens and ways to change it?
Thanks a lot.

Have you checked apn setting and made sure they are correct for ATT?

I tried configure the APN setting based on a link online for ATT APN. Now I am losing signals even for calls and texts....I think there might be other things that are wrong...

Error message for no ATT service
Tried different variety of ATT APN setting. Still could not get it to work....the phone shows a signal but gave me an error message that Selected network(AT&T) not available

I'm not sure what did you mean by "data roaming"??
Anyway, the problem for now is no network register. The APN settings will NOT affect at this step, so not not try to mess up with it right now.
Try to get into Settings > More networks > Mobile networks, and set Network mode to Auto connect, and Network operator > Select automatically.
That may help the device to register on the Home network.

Problem solved....or maybe not but it is working!

Okay. Thanks. I switched it back to the auto-selection mode. By data roaming....I mean 3G data. My phone is working now. I checked ATT billing usage report, it did not increase the data usage dramatically so I guess everything is fine.

Glad that your phone works now.
BTW "data roaming" and "3G data" are different things. "data roaming" is "3G data" when you are roaming to another network (not your home network).

[Q] 4 G LTE and 3G not working on Yureka

hi,
i bought a yureka, everything is great. its just that i'm unable to use 3G or LTE on my device.
it always shows edge. on my device. and runs 2G
in mobile networks preferred network type is LTE. and i have LTE service in my area.
on phone info *#*#4636#*#* By default the preferred network comes as LTE/GSM auto(PRL) and network type shows EDGE.
i have tried changing the preferred network to WCDMA preferred, then radio on/off, still network type shows as EDGE.
i have unlocked the boot loader and then flashed the modem (NONHLOS.bin) from Rohan A joshi thread in XDA yu yureka.
still im unable to use 3G or LTE.
the SIM is perfectly fine, if i put the SIM in some other phone like iphone, everything works fine.
can someone please help me i will be thankful.

Try WCDMA Only
---------- Post added at 01:38 PM ---------- Previous post was at 01:38 PM ----------
Or disabling one sim which isn't meant for internet

I am also having the same problem only edge,and phone info shows as "gsm only " no matter what I do its not changing to wcdma or any other options help

no idea, im also still waiting for any reply

Partial solution found.... On LTE sim slot i. e. Sim no. 1 using *#4636#*#* and then select wcdma will change the network to 3g.
But 2nd sim the wcdma option not activate.

Same problem for me too
I'm also facing the same problem. Selecting WCDMA only option is not working. It always comes back to GSM only mode. End result no 3G and hence no internet. Only whatsapp is working. Should I ask for replacement. 10 days is not over for me yet..

Finally 3G actually work on YUREKA
Finally after lots of hit and trials I got solution.
Two things you need to do.
First
a.select default type as WCDMA only
b. enter *#*#4636#*#* from keypad.
c. Go to Phone Information and turn off radio.
d. Now select WCDMA only and click on turn on radio
Second
Delete ur APN settings and set the setting manually as per
your service provider. search setting on google.
Finally MY YUREKA WORKING ACTUALLY ON 3G NETWORK
Note : Preferably do all settings on SIM 1 inserted in LTE slot

WCDMA only
I did that. Fortunately this time I'm able to select WCDMA only. Device started working in 3G. Now when I go home, again 3G is gone.
Did that selecting WCDMA only again. 3G is back.
Every time I need to do this like selecting data connectivity/Wifi. I'm getting sick of this. Unfortunately 10 days period is also over

Finally 3G working..
Hey Guys,
If anyone here still facing problem with the 3G connection.
Deactivate your Mobile Data Connection.
Try going to APN setting remove the Proxy Value and Port Value then Save it.
Finally, activate your Connection.
Its working for me.

This is not a bug
check on forum
that problem of APN

hello,
i dialed in *#*#4636#*#* and got that menu the first time i turned off radio and selected wcdma only and turned on radio then rebooted.
i dont know why but it says no network available.
so i changed it back to lte/gsm after switching off radio and then switched it back on. i got the network back still on 2g.
but now everytime i reboot it goes back to wcdma only and no network available..
how do i make lte/gsm the default network so that i dont have to keep switching networks when my phone boots up

I have had this problem too in a while. But I guess it go resolved somehow.
First there is SIM 1 which is only good enough to run 3G or LTE networks.
I tried a lot to run it.
Sometimes switching on and off the airplane mode gave me the 3G connection.
Not sure about LTE, the national capital still doesn't support LTE.:good:
Give it a try!

Guys first of all you need to know that only SIM 1 supports 4G LTE.
and both sim slots supports 3G but you need to get activate 3G Services on your number.
i am using 3G of Aircel and its working fine for me(Sim2).

I just changed to WCDMA only and 3g started working.
My issue was 3G will work for a day then changes to 2G. Then I have to remove the sim and change slot for 3G to work. Will wait and see how long this will remain 3G.

Good 2 know

Hey Anurag, Can you please post the APN details of Aircel that you have on the Yureka? I have tried that *#*#46 etc and changing SIM from SIM1 slot to SIM2 slot. No difference. Still on EDGE.
Thanks,
Kiran.

Setting as mine:
Name: Aircel
APN: aircelgprs
MCC: 405
MNC: 810
APN type: default,supl
APN protocol: IPv4
APN roaming protocol: IPv4
if still not working go to your nearest aircel service station..

Thanks Anurag. There was some issue that even though it was same setting that I had, I still could not get 3G. Anyway, I upgraded to Lollipop and the problem has been resolved. Now I can get it to work on 3G Speed itself. Same APN "aircelgprs".
