I've bought E6533 for nearly 1 month, but I still can't find WCDMA signal.
When I select "LTE/GSM", phone is on LTE, but I can't receive calls(it doesn't fall back to GSM).
I try to set "WCDMA only" and got no signal. At that time I know that my E6533's 3G is "broken".
I flashed many ftf from xperiafirm and factory reset for many times, but doesn't work.
Please help me out, what should I do or should I flash?
(My carrier is China Unicom)

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..

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.
hi there..got i9305 and its got a strange problem that every time i change the sim card it cant detect the sim cards automaticly and i have to search networks manualy and select it..then its works fine with all sim cards like t mobile phone o2 vodaphone but only with 3 sim it cant connect to network and always says mobile networks not avalible..
its was locked on EE and i used the free methoed to unlock it from xda..
please help to solve that problem
thanks
Go to Network Settings and set it to "WCDMA only" or "AUTO" mode. You CAN'T use 2G only for Three UK as it is 3G ONLY network. If this doesn't work then try different sim-card or try different Modem/Rom. Nothing else's coming to my head.
It's all OK here, 3UK as well, my i9305 was locked to T-Mobile but I've used a Unlocking Code from eBay and simlock is gone for good.

GSM=2G, WCDMA=3G, LTE=4G..................
UK Three is a 3G ONLY so you need to set it up 3G ONLY... leave it for couple of minutes, if still nothing then re-install modem
thanks for your help again..just one thing where can i find just the modem for this model..?
thanks again..

Hi,
I'm not getting any 3g signals on my Xperia V after flashing back to stock.
What I did:
1. Had CyanogenMod 11.x on my Phone for years. Worked just fine.
2. Switched to CyanogenMod 12.1 (Neo's Homebuilds) a few weeks ago. 3g still working.
3. Wanted to sell my phone - cause I got a new one - so flashed back to stock (9.2.A.2.5 Customized DE) using "XperiFirm" from Flashtool
4. After flashing 3g wasn't working anymore. Every time the phone switches to it I have zero bars and a red "x".
5. After switching to "only GSM" and a reboot I had a stable 2g connection. But as soon as I try to turn an 3g, I get zero bars and a red "x".
6. I switched back to CyanogenMod 12.1 (Neo's Homebuilds). Same problem - zero bars and a red "x"
7. Tried several different stock roms found in the "STOCK FIRMWARES for Xperia T,TL,V,TX" thread
8. Locked the Bootloader und used Sony PCC to repair my Phone
9. Did a factory reset
Additional info's:
I live in Germany
Provider is "o2"
Sim works in a different phone
Can't try out 4g since my provider doesn't offer it.
Everything else is working just fine
The phone is in a really good condition and would get me 100€+ easily. I really hope it is something that can be fixed.
So if anyone can offer some help I would appreciate it.
Try unbranded ftf Nordic or central Europe
Tried them all. No change.
My SI is 1270-9179 which is "Customized DE" if the information in this post is correct.
It is really wired. While finding the 3g networks in 2g mode, it behaves like there is no network at all when it switches. Doesn't even find 2g networks anymore and I have to switch do GSM only and reboot. Only emergency calls are allowed and under "Settings > About phone" it's looks like there is no SIM card.
Have u tried 4.1.2 or ICS.
And try with a different sim card
Hello guys,
I am using the C6903 variant of Xperia Z1 (purchased from Saudi Arabia) in India. However, the phone struggles to connect to the LTE network. The 4G network shows up in the list of networks, but on selecting it, it displays "Could not connect to the network now, try again later.".
So I dialed *#*#4636#*#* and selected LTE only. It did work once and the LTE signal indicator did appear, and internet was working for approx 5 seconds, but the signal was very weak and I lost it very soon. Will check if it is a range issue tomorrow.
Using a custom ROM(Stock based) [MX ROM] and a custom kernel (RockZ1L). Is it a baseband issue? Please help
Update: it seems that my providers representative was lying when he said that the area where I live has 4g signal. Went for a little trip and lte seems to be working fine now.
I have got moto-x xt1052 running lollipop Asia version
Network works fine in gsm (2G) mode but it shows no service in 3G and LTE mode
Vodafone IN 2G works not 3G and 4G, Reliance JIO doesn't works since it has only LTE
I tried resetting the phone and flashed the stock rom
Run test in *#*#INFO#*#* mode, in SMSC it shows my number
Even flashed the modem files but also it show no service
How can i get back LTE mode?, help me guys
Since a few days ago, my Moto X also has no service, regardless of what the preferred mode is set to. It simply sees no carriers at all. Anybody got an idea how I can debug this? One idea is that the GSM antenna has disconnected itself somehow, but I don't even know where it is.
