Hi,
I've been using my Xperia Z3 D6603 for about 2 weeks now on the Virgin Mobile (Bell Mobilily) network in Canada and the network reception is horrible. The signal keeps bouncing from 2-3 bars to zero bars wherever I go. My habits have not changed since using an LG G3 which I never experienced signal problems with. I think it's something to do with the phone not being able to connect to GSM and connects to CDMA only. I think this bc when I go to GSM only under network settings it won't connect at all.
What I've tried:
- Installed generic Canadian firmware
- Went to GSM only under network setting, and have NO Signal
- Entered Virgin's APN settings
Does anyone else have any suggestions?? This is such a nice phone and would love to keep if I can get the signal issue fixed.

Ok then it s better to take it to service center to check its hardware
:good:
Oh man, I really hope it's not hardware...
This might be a dumb question, but are you sure you have D6603 and not another variant?

Hi,
Any AT&T Atrix2 users in the Netherland ?
I've just arrived last week and I couldn't get a stable data connections. I know it's not a network problem because my friends don't have any problem. So I'm wondering if for some reason it's my phone (radio incompatibility maybe).
Most of the time it just won't attached to the network, other time it attached to the network but data is not flowing.
SMS/Voice call are doing fine.

Anyway, don't think that the problem is with the app, cause from time to time, I could have connection (a very fast one I have to say), but most of the time, no traffic are coming through.

And you have tried your connection from the same locations as your friends, who are also using the same mobile operator?
I use a SIM unlocked AT&T Atrix 2 in the Netherlands with no problems. I'm on T-Mobile NL and live in Amsterdam.
I have had problems with my phone failing to connect to a data network when I travel outside of the Netherlands, though. It'll get itself into a state where it won't send or receive data even with the "data roaming" option selected. I've always been able to solve it by rebooting the phone, but that's a crappy solution. Does a power cycle fix it for you?
recently ive been all around(Ger,Aus,Slo,Cze,Hun) europe with data roaming on, and i had data(and phone ofc)just fine where i wanted it. im with vodafone.
unlocked att atrix2
I think it might have something to do with the radio. Force my phone to 2G and connection is very stable.
Might be related with me living in Maastricht which is quite close to the border.

afaik the att 3g bands dont cover all the european 3g gsm bands, its rare but you might be unlucky... you have to see specs of a2 and your providers bands.

Some of European providers use 900MHz band for UMTS which not supported by A2.
So in areas without 2100MHz but with 900MHz UMTS our phone will not work in 3G .
What I find it strange is, when I'm on 3G, phone and sms work just fine. I got a full signal also. That's why I don't suspect radio problem.

When you're on 3G, it SHOULD work fine.
If you meant "when you're not on 3G," then that is still normal. Different radio bands handle different tasks from your phone - SMSPhone being examples. You can still be "on network" and not have 3G data connectivity.
If you take a trip to a different city in the Netherlands and your 3G works fine, you'll know the problem is with the radio bands your carrier is using/not using in your home area. If your connection is still bad, then you have an issue with your phone itself.
^^
that is correct. its not so simple as "sms works so data should too"
in this century less and less people are sending sms and calling, compared to the growth of mobile data usage. but the number of bands on the avaliable frequencies didnt grow at all. so networks adapt to it, different bands are becoming data bands, and small unused bands are becoming phone bands, and so on..
Bougt a Nexus 5 32GB D821 in December in England on holiday. When i came back to Norway the 3g/4g network worked fine but I dont get any signal when i switch to 2G.
I live on the coast so sometimes I lose 3G signals and then I have no signals at all.
I have testet the sim card on my old S3 and there it works fine. Since i bought it in England I have no warrenty and no one will fix my phone.
Is it an hardware problem or software problem?

I have my N5 2 days now and I experienced simular issues.
The 4G symbol would come up but when that leaves, probably due to almost no signal, no 3G, edge etc.
I solved mine by switching it to setting - more - mobile networks - preferred network type ---> 3G ... so far so good.
I also had issues with my wifi on my Asus RT-N66U unit. It would be connected but no wifi at all. reconnect and it would work for a couple of minutes too.
I reflashed the firmware of a couple of months ago and no more issues.
Please let us know if it works for you too so we can help others!

I have testet with prefered 3G and also only 2G. When I choose 2G only I got no network at all. Some people think it is a motherboard problem.
About a month ago I was in an LTE area and browsing xda and noticed a radio update so wanting the latest version I immediately flashed it. I noticed on rebooting that my lte wasn't working and I thought that the settings had just been corrupted but after a full re flash of the system and the modem I still can't get LTE in an area where other 4G phones can. However my HSPA+ works fine pulling 20mbps next to a cell tower.
Wondering if anyone can help?
Network details:
Three UK Lte bands 3/20
Phone
Nexus 5 D821UK
Why don't you flash the old radio on which LTE worked fine?

I did, still no change. I thought that would be the solution too. I might be onto something but not sure? On the APN settings does having the bearer set to LTE make a difference, I never noticed before but noticed that it wasn't set now.
Dear XDA community
I have a D821 device and since I started using mobile data I noticed that I was having a very unusual issue. I was getting only 2G and 4G signals with greek carrier COSMOTE GR & VODAFONE GR. Max signal on cosmote was Edge and when on 4G coverage 4G. On Vodafone I'm getting GPRS only. Any member had any similar issue and any solution to Fix it? Can it be a software issue or hardware?

I think that this is just about coverage and signal strenght of your providers.

I see that you are from Manila and using a F350L please check supported bands by your network and the supported bands of F350L if they are compatible.
i did check it and it is same bands use here. there are f350L users here with no problems using their 3G connection.
My F350L is LTE-8 other F350L are LTE-A. I suspect that this two have different band
I am having the same Problem up here in Ohio
No matter what I try I can not seem to get this phone to do anything besides just G I am running the F350S on AT&T
Please look in Dialer with 5457#*350# and activate your Bands
Still no dice

Hi folks, I am Nigerian and I use an LG G Pro (D838). Some days back i noticed that i had no network on my phone so I tried inserting another sim into the device and still got the same result but other devices around had network coverage. I changed the network mode to GSM only and got 2G but WCDMA only gives me nothing. I have tried other sims on GSM only mode and got 2G but when i change the mode to WCDMA only, i get nothing at all. Have also put it to GSM/WCDMA auto but keeps giving me just 2G network only. I have even had to downgrade the OS from android 5.0.1 to 4.4.2 as suggested by a friend and still got the same issue. Please, what should i do??????
Same problem overhere Lg g pro 2 though F350k
I have the same problem in Holland. I have the F350k variant) 3G is in Holland 900/2100. The phone has despite of the advertisement text !!! by selling (900/2100) 850/1900/2100. The 2100 band is the same so should work.
Tried a lot. By the way last software and Androi 5.0.1.
The Sim is not the problem, the APN setting not, ........
any suggestions?
Could it be somewhere oleh software??????

Hello, I am from Nigeria.
I bought my LG D838 on eBay in May 2015 and was quite impressed with the performance but my pride and happiness was short lived. I woke up one morning in December 2015, and noticed I didn't have any cell reception. I checked with my siblings and I seemed to be the only one who had no cell reception on the same network as theirs.
I swapped SIMS of other networks into my phone but still to no avail but funny thing was that whenever I change network mode to 2G only, I get reception but switching back to 3G only mode gave me nothing at all...this happened a few days after I updated the OS with a 50MB patch file using OTA as prompted. I have been writing to LG since then but no reply and it has frustrated me so much as I bought this phone for about USD 398 and didn't even get to use it up to a year. I managed it on 2G while trying to contact LG about it until the Wi-Fi and Bluetooth stopped responding also. I need the NV and QCN backup file for this phone in order to get it running again…I would really love to see this beauty run again. Please help me out.
You can contact me or send the file to [email protected]. I am open to suggestions.
Thanks in anticipation.
