Desperatly need help getting 3G instead of E

Hi guys,
I brought my first xperia from my phone serivce provider, and it always had the "3g" symbol at the top. However, when my xperia broke, I had to buy another one and got one of ebay. Since I brought the new one, my phone always has the 3 on top. I'm currently using the firestorm valkyrie rom which as the htc interface. When I go to the data connections it says an option (3g) "change to gsm mode" and on is selected. Even when I toggle that, it still always has the E symbol. What do I need to do? I know my sim card is cabable of getting the 3g. But this is a real pain because every now and then my phone just doesnt receive service, so I constantly go onto the comm manager and then it seems to just click that there's service and shows 2-3 bars. Then all of a sudden again after a while there'll be no service. So I'm guessing that's because of the E thing. It shouldn't be my current location as I've never experienced this before.
Is there a setting I can go to to get the 3g symbol? Or a patch I might need for the phone?
Please help
Kindest regards.

You need to change while the connection is not active, I believe. Or... you got the Xperia version incompatible with your network... Or... the ROM is buggy, try another.

sorry, I need to change specificially what when the connection is not active? Say you mean, turn off my phone settings and not connect to the network and then adjust something? It is not the rom. and the seller on ebay has stated that it is a 3g phone - many others have brought it as well with no complaints.

3G settings on x1
Hi
For some reason your phone is only camping on the GSM network (G or E indication depending if your carrier provide GPRS or EDGE on the GSM) instead of the 3G network (which you have been using before).
In settings, communications you should be able to set "3G change to automode" to on,
When this is set your network provider will tell your phone to use the 3G as preffered network, but when coverage is not good enough it will drop you back to 2G (which has a better reach due to lower frequency band).
If it does not happen automatically there might be another setting that is wrong,
goto settings, all settings, personal (tab), Phone.. then choose the "band" tab (need to go to the left with the arrows) , then you have the dropdwn lists to set:
select you network type (need to set auto or wcdma to get 3G)
select your GSM/UMTS band (need to set 900+1800 for europe, 1900+850 for us, dont know who is using 2100+800)
once changed the phone will restart the phone part and search for your carrier in the right band.
good luck

Hi,
Thanks for your reply. I had changed the automode to on. But still had the E.
I went to the setings, and band tab, and i had selected:
Select your network type:
(blank)
Select your GSM/UMTS band:
Auto.
I changed the first oen to auto, and as for the last, here in Australia I'm with Tesltra which is 850 UMTS? I think I read online. Anyway it didn't have the option in there, so I went through them all but wouldnt get service at all except for the first: GSM (900+1800)+UMTS(2100+900). and Auto. I think my last experia might have had auto for all of those too. Anyway with those only two options working, I still get the E icon. Even tried setting aeroplane mode on and then off to see if it might register, but it didn't.

I see , Telstra is one of very few networks that use 850 for WCDMA so they might be using a different RADIO ROM than the rest of us
I saw in the thread below that there is a TELSTRA AUSTRALIA (1.03.841.8) R2AA008 version..
http://forum.xda-developers.com/showthread.php?t=477801&highlight=telstra
you probably need to flash that one to get the 3G working on telstra..
3 is using the normal 2100 so you could also try with their SIM just to check that there is nothing wrong with your hardware..

Sorry for the late reply.
I have realised that i'm in an area that doesn't support 3g. however my last xperia phone which I brought from telstra was the x1a, which had the next g network - hence I got the 3g symbol. However I have found that that I have the x1i, which doesn't list that network. I rang up telstra, and they transferred me to the sony erricson call centre, and they said you can try and do an update but it is not gaurenteed to get the next g service. I have already flashed a htc rom and don't particluarly want to change it back, unless i'm certain that I will get the next g service.
With the rom you have provided, do you think it will have the UMTS 850 band on there, and my x1i would be able to connect to it? I would have thought that it would be a hardware preference, not a software. In which case, even if I updated the rom because there is say no "chip" that allows for connecting to that band, it wont connec to it even though I may have selected the 850 UMTS band.
Sorry if that seems all over the place, but yeah... I'm not sure.

Force WCDMA Only

Hi all,
Would like to check if anyone knows how could i set "WCDMA Only" (3G Only) on Galaxy S?
I can only Force 2G only via the settings menu, but not 3G only.
Managed to access the "Phone Info" menu via *#*#4636#*#*, selected "WCDMA Only" from the dropdown box.
However, nothing seemed to be set nor i see any button to save the choice?
Anyone happen to know how can i have it set? Or i could manually set it by applying some settings somewhere?
Thanks alot!

you cant force 3g... you would get no signal if you didnt have a 3g connection

*#*#197328640#*#* > debug screen > phone control > network control > band selection
You need to do this after each reboot though as it does not stick.

Is there a way to shortcut this with anycut?

The app Network simplifies the procedure quite a bit. Haven't actually gone into a low signal spot yet to see if it fully works as intended though.

thank you very much..i have been searching this high and low...you save my day..

Thank you so much! This helped me diagnose the SGS and see if I have 1900 3G in my area (1 bar). here's a tip that I used for quick access to the debug screen just as a trial and it actually worked
Enter ONLY *#*#197328640#*# then hit add to contacts (notice there is no * at the end).
Give it a name (Samsung Debug Screen) and tap to edit the number and enter the final * at the end.
Save and exit. Now whenever u want to enter debug mode to change the network or other stuff just type *#*# and it should appear. Tap on the contact and voila!

Awesome, thanks for this! Lots of fun debug info in there.

My operator doesn't have a 2G network... all they have is 3G. There's no point in my phone looking for anything other than a 3G network.

Solution added to FAQ

sorry to ask if this is already answered but how exactly to i get to CONFIRM my wcdma only selection? i check it and nothing happens, data connection stays on "G" symbol. I know for sure that at the place where i tested i get NO 3g signal. which means probably that i should be losing all signal after choosing wcdma only. that does not happen. also if i close the phone info app and reopen it, choice gets back to default (3g/gprs).
any help appreciated... I really need this.

forcing to only 3g is a bad move, i tested it on my n1 and i kept dropping calls once 3g lost signal.

Its available in the new firmware I9000XWJM1
Hey, its there in I9000XWJM1 and tested working great as expected! However its a beta so you may see other issues. Not sure if its there in latest stable.

Just to confirm, i upgraded my firmware to XWJM5 today, and i noticed that in settings > wireless and network > mobile networks, there's a new menu 'network mode' in which there's 3 options - auto / gsm only / wcdma only. Nice touch!
In answer to the cynics, there are times when browsing, when the phone is borderline whether to give you 2g or 3g, it does come in handy, and it's safer too, as if i have to browse on 2g it makes me want to smash the phone up!!

LOL "safer"

@OP Although 'WCDMA only' mode may not be a good idea and hence not recommended but just to confirm
my current Build i9000XXJPH have following three modes
GSM/WCDMA (auto mode)
GSM only
WCDMA only

JM8 build also have this mode. I noticed that when I flash the i9000M (bell version) previously it didn't have these modes.

why no Edge network?

Hi all,
i am on O2 Germany network and using AT&T nexus one.
i get 2-3 bars of HSDPA(H /3G, 2-3Mbps) network at my work location but if i move little far from my seat (near to window) i get only GPRS(30-50 Kbps) network but my friends Iphone manages to get Edge network on same provider which my Nexus is not able to get.
can anyone tell me why is it happening so and also i have tested selecting EURO band under phone info settings but no use
TIA

go into the dialer and type *#*#4636#*#*, go to phone information and tell us what setting is selected under Set preferred network type

hmm thats not the issue then as WCDMA preferred can still grab an Edge signal, have you tried turning 3G off and see if you can grab Edge anywhere?

i have switched off 3G too but still i am not getting Edge........
can anyone help me plzzzzzzzzzz

Bump.......for the convenience of all to see and help me out

Seems to me you're never going to get 3G, so I'd personally set it to one of the other options, not WCDMA. Don't have the phone in front of me but think the option to pick is clear if you're only going to get EDGE.

[Q] Network issue

Hello Team,
i purchased a unlocked HTC one and i use a AT&T gophone sim card. i am not able to get the LTE signals so i would like to know is the phone capable or its an issue.

This happened to me a few months ago. The phone is definitely capable and you will get LTE signals on the $60/month GoPhone plan.
1. First of all, call GoPhone customer support (611 from the phone) and confirm that they have your HTC One whitelisted for LTE. They're going to double check with you your phone's IMEI number (they can already see it, but will ask you for it anyway), and then confirmed that the phone is allowed to get LTE signals. They're also going to double check your APN setting and provide you with the appropriate entries for AT&T.
2. Reboot and see if you now get LTE signals. If you still don't get it, check whether your mobile network settings is set to GSM/WCDMA/LTE Auto instead of GSM/WCDMA Auto or WCDMA Preferred (or maybe something else). If you don't see any LTE option, dial *#*#4636#*#* from your dialer, and in the first drop down box choose 'GSM/WCDMA/LTE Auto' or anything with LTE just to make sure you can catch LTE signals at all. If you were able to find and switch to the setting you want, exit out, and go back to that menu, double checking if the setting sticks. If it does, reboot and try again.
3. Most people will get LTE signals after #1 above, while some were only able to get it after #2. However if you are unlucky like me, the LTE setting does not show up in mobile network and no matter what I do in the hidden menu, the setting won't stick (it's stuck on GSM/WCDMA Auto). I actually tried flashing a different radio at this point (a newer AT&T radio), but still... no LTE for me. What solved this finally for me is that I flashed a custom ROM (in my case it was ARHD 12.2). This enabled me to choose GSM/WCDMA/LTE Auto under mobile network settings, and after that I was able to get LTE. It was great! :good:
Hopefully that helps. Good luck!

Ok I change it but it only gives me these options
Preferred network type
2g / 3g / 4g lte
2g / 3g / 4g
3g / 4g
2g only
If I put it in 2g only, it allows me to make calls
The problem of the update is that I add a new option called
4G LTE MODE IMPROVED when turning off the signal
