Ok guys Here is my problem
I live abroad and I have a Verizon Galaxy S3 with unlocked SIM capability so I'm using it as a GSM phone. The problem is that my GSM network provider does not have a 3G network, however, there is this other mobile network company that does offer a 3G network but it operates on CDMA. So I flashed my phone using DFS to the CDMA network and I managed to get the phone work for both calls and Data. But now since I usually use my GSM number I have to switch back and forth between GSM and CDMA whenever I want to use data and that is pretty inconvenient, in addition, whenever I use 3G I loose my GSM connection.
So what I was thinking is whether I can activate both my GSM network and the 3G connection from the CDMA network at the same time so that I can surf the web with 3G speed and make calls using my GSM number at the same time.
To be honest with you I've been trying to get that done with no hope, I've tried all the modes the "Phone info" app with no luck, so I'm here now asking for your help.
come on guys
I can't believe no one here does not have an answer
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?

Is there anyway to enable UMTS 3G on this version of phone. I have used the hidden LG app and selected auto select GSM/WCMDA/LTE but I cannot get any 3G service. All I get is 4G/4GLTE or EDGE and nothing else.
2G service will be stopping soon here and I won't be able to use the phone when in EDGE mode when that happens.
I am on Vodafone in AU and live in poor service 4G area but good service 3G when I used my old Note3. I have also tried a Telstra 4G SIM and the same happens.
Looking at spec for this phone it is radio supported for 2G/3G and 4G but I suspect AT&T may have locked out 3G service.
I cannot find a non AT&T ROM anywhere so I suspect I am stuck with AT&T for the moment which I suspect this may fix the issue. But any help would be appreciated.

Strange, because using the same app I'm able to change the network mode from 2G to 3G with ease. And it works well.
Phone is OK
OK the AT&T V10 has no 900Mhz support but has 850Mhz support and 2100Mhz support
After many contacts with Vodafone AU, I found someone that knows their stuff. They tell me coastal areas have 2100Mhz and inland where I am is 900Mhz, so problem not solved but understood. But if I have a Telstra AU SIM they support 850Mhz which this model has.
I bought an M8 last month and with a luck like mine I got a Verizon variant.
The problem is it won't connect to 2g networks ( connects to 3g and 4g networks fine. )
First I thought Verizon variant won't be supporting GSM or 2g networks but I did my research and found that it supports GSM networks. My network gives excellent coverage for 2g in my area . My network's 3g and 4g coverage is really poor in my area so I am left with 2g only. If I set it to global mode, it will connect as long as 3g or 4g signals are available but will go on limited service once there are no 3g or 4g signals.
In network settings if I select GSM only it does not work. The network mode remains unchanged . All other network modes can be selected but not GSM only.
Even by dialling *#*#4636#*#* I can't select GSM only.
If I set it to GSM/UMTS/LTE it will connect to only 3g or 4g but will show limited service once there are no 3g or 4g signals .
I have tried a patch for Verizon phones with no 2g options but still no use.
It would be nice if I could any help what could be the problem.
It can't be hardware related because if the modem is damaged then 3g and 4g should also not work.
