hi everybody
Can someone help me?
I am susing d2g outside us, but I can't make a call.
It appears two problem.
First,when I call someone,the phone will auto reboot.
I call to someone,can't hear voice,just nothing.
3g and signal still work.
Thank you
ok I have found the answer.
Seems d2g doesn't support my country WCDMA .I can only use 2G for calling.
This is my country 3 g 1O1O / One2Free GSM 900 / GSM 1800 / UMTS 900 / UMTS 2100
BUt D2G is support umts 2100,I don't know why it won't work.So sad
Hi, Andy, are u Hong Kong guy? I am from Hong Kong and have the same problem. I am using PCCW 3G plan. If the phone connects to 3G network, no sound can be heard or sent to the receiver when making a call. No problem found if 2G network is used. Have u solve the problem? or may someone help me? Thanks.

yes, I am hk user.
I have try 3 network provider,pccw/3hk/csl.
Only 3hk can work on 3g calling,but you know 3hk wrost network
I have tested D2G using Smartone SIM card. It is no problem on both conversation connection and 3G data connection. The Smartone network is not bad and you can have a try first before you switch your ISP.

Hi, I bought the defy about a month ago. I bought it in south america. I live in Italy, so, when I came back, and tried to connect with my phone to the 3g network it didn't, just the GSM (the little G on the top). I'm currently using CM 7.1, but with the Defy+ ROM it did the same. Now here's a strange thing: i searched over the internet and find out that with the Defy baseband I could change the band for the Italy one, but, I'm vodafone, and the network with Italia RT on the baseband says Emergency calls only. So I used the International RT, and it worked. I thought it may be the device, so I inserted a TIM chip, but now instead of GSM I get EDGE. WTF?
I know vodafone uses 900/1800/2100...any ideas? It is possible that because I bought it elsewhere I can not connect to 3g in europe?? (even if the defy's manual says it works on Quad band GSM with GPRS/EDGE (850/900/1800/1900 MHz in all regions)
Dual band UMTS with HSPA+/HSUPA (850/1700/2100 MHz in the USA, 900/2100 MHz in Europe, and 850/2100 MHz in Australia, New Zealand and Thailand)??
Thanks for the help!!
Please, help me get my 3G back!
No one can help me? Even a hint would be great.
Thanks

Use baseband switcher dude

As I said before: I used baseband switcher, but it doesn't change anything. I wonder if the 3G fixes on other forums are the same as baseband switcher

for 2G networks, Edge and GPRS are the data connections available.so G is for GPRS not GSM. E is for Edge (both E and G are GSM 2G). some networks have GPRS and Edge depending on the location, some only operate GRPS, it depends on the priority network planning etc..
when you tried different SIM cards you used different networks and thats why you have G or E, depends on whats available for that network in that location.
as for 3G, what country did you buy your Defy?
italy has : 900/1800 for GSM and 2100 for 3G/UMTS
south america:
-brazil has 2100 and other bands for 3G/UMTS depending on region/operator
-other countries in south america have no 2100 but only 850/900/1900
good article here on wikipedia
http://en.wikipedia.org/wiki/UMTS_frequency_bands
sadly the 3G radios in most phones are carrying one and not all frequencies so your device is as small and cheap as possible.

Does that mean that even if I use baseband if my phone doesn't have the 2100 will not work in 3g? I bought it in colombia. Thanks for the answer btw. There's any mod, way to give my phone the 2100 frequency? Maybe changing a hardware part? O just I should change the phone? If I change Rom does it do anything? Sorry for all the questions

In the box says made in brazil. Don't know if that's of any help. Any way I can change the 3g radio??
changing roms or baseband is of no use unless you have correct radio. did you use the phone in colombia? did 3G work? if 3G worked in colombia it will not work in Italy, if thats the case i think easiest is to change your phone if you want 3G, not sure if anyone tried to mod radio.

Yes it worked there. Well, thank you for the help, I think I'll keep this for a while, but at the end I'll have to change it. I'll try to ask if maybe some other company use the 850 or 900 here also for 3G. I think, if the topic is solved. Thank you nolimizz.

Hello,
I bought a new device, Nexus 5 from China
And I have a problem when I insert SIM regardless of which provider I have no reception (no service),
Tried to set the correct APN settings with the provider but it didn't help.
It works out only when I'm working on 2G when I return to 3G again no reception. (No LTE in my country - Israel) .
I can't find any operator after switching to 3G.
when I switch from 3G back to 2G I still can't find operator only after a restart.
Do you have any data about my problem? and how\were can I get service support in my country? Thank you.

Same problem here...anyone?
Well, depending on your operator, 3G frequenties used maybe not the same as the ones uses in China.
I know that USA LTE(4G) isn't the same as here, in France (If not I would have bought it in USA for 349$, that equals to 255€. And I bought my N5 349€ in the play store)
Try to call your operator and ask them for the frequenties they're using ?

Are you sure this method workd for the problem I am having? Please note that I can select 3g but its not getting any network while others have problem where they cannot select 3g. I am asking here before following the video so that I do not mess up my device.
I'm from india.
Im using BSNL carrier on nexus 5. I have kinda strange problem on my phone. When i select only 2G mode i am not getting any signal.but if i change it to 3G or LTE im getting 3g signal. But in some areas in city 3G not available only 2G is available but im not getting 2G signal. I changed carrier to IDEA and VODAFONE still facing same problem.2G not working only 3g.
But in airtel and reliance 2G working ok.
For solution i have flashed new rom but not working also flashed RADIO files provided in xda forum but still same problem.
If u have any idea what to do please tell me.im about to swith my carrier due to this..
Thank you.
Hey guys,
So my Nexus 5 stopped working the other day, and I sent it for repairs. It's come back now and I got a new SIM. Airtel 4G here in New Delhi, India. The problem is, it will only show me a 2G connection/no signal at times. I don't know what to do. The SIM works in other phones perfectly well. I've tried going to *#*#4636#*#* and changing to WCDMA only. Doesn't work. What is the alternative solution guys?
The phone was bough in the USA but before it got repaired, 3G worked flawlessly. So at least that should work, if not 4G.
Thanks,
Crazysah
No one has had this problem? Or no one knows a solution?
Hi, Airtel as I see operate in 2G (GSM, EDGE), 3G (HSPA+) and 4G (TD-LTE band 40). But Nexus 5 (USA model) D820 doesn't support TD-LTE (band 40), so for sure you can't connect to 4G. But 2G and 3G should be ok. You can reset network settings and check again.

Yes. 3G should work at least. But it isn't and that's the problem. Before repairing it, it used to work with my mom's Vodafone 3G connection. What's the solution here?
Can you try to restart and after that change to "GSM auto (PRL)" from *#*#4636#*#* menu? Are you tested other device with this SIM in the same location ?

Tried that. With no luck. I changed it to GSM auto (PRL) and stayed on that menu. Still showing E with full signal strength.
Any idea guys?
Nobody at all has any solution to this?

Hi guys, i'm using N920P with China Mobile network now, i have a problem that is if i change the network to GSM/UMTS, I can't use 3/4G, but i'm still able to make or receive phone calls, but if i change it to LTE/CDMA, I can use LTE now but I can't make phone call anymore. I'm wondering what's the problem with my phone. Hope that someone can help me to fix it. Many thanks.

You can't use China Mobile 4G. Only way to do is to switch to China Unicom or Telecom, China Unicom supports 4G but may not be able to call at same time, but i think 3G is perfect, and you can use China Telecom 3G too. You can install a patch for China Telecom 4G but I don't recommend that. Otherwise you can bare with the 2G speed...And don't trust those people online who want to charge you after adding their QQ or wechat.
@sonvu2110 Try this rom http://bbs.gfan.com/android-8394771-1-1.html

I didn't try yet. but it says N920p supported. If u are on sprint, am not sure how it works.. but GSM should work well.
