has anyone been able to get data service via their verizon sim in shanghai or hk? no problem with voice coverage, but i've had data coverage in shanghai maybe 5% of the time. i couldn't deal with no data in hk and picked up a pccw sim, which works great. their HSPA+ network is pretty solid.
interestingly i've had the same issue with a 3 HK prepaid sim. totally fine voice coverage, no data (on their UMTS network). no convolution of APN settings has done the trick.
i'm on mf1 & liquidsmooth 2.9.
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
...............just like the title says........is it possible?
I live in a border town with between USA/Mexico. I have the Mexico ad on so I get 1000 mins to use as if I where in the USA, but while being south of the border.
I noticed today, WHILE IN MEXICO. that I received a couple of emails by the notification sounds....it surprised me because I have selected "Deny Data Roaming Access" in the Global Data Roaming access menu. STILL I get the 4G LTE icon and therefore my device has data, BUT my voice service is ROAMING.
Is this possible?
Can I be int'l roaming voice and still be on VZW 4G LTE at the same time???
I even went and turned airplane mode so that when it connected again, it would ask me if I wanted to deny roaming data, I doubled checked to select "deny" and still my phone would be using data with the phone roaming, but with the 4G LTE icon and data access at the same time....
There is NO 4G LTE south of the border (there is but with a different carrier and different freq.), so there is no way it could have connected to int'l LTE, and on top of that by me "denying" access to roaming data.
I know voice and data are split in 2, that the sim carries the LTE duty, and CDMA does the voice duty, SO, it is in plain paper possible since the LTE signal is strong enough to reach, but the CDMA isnt, so it roams........
Also, if its really the case, wont VWZ rape me a new one by charging me int'l data since I actually was roaming according to the CDMA signal.
Anyone care to enlighten me???
Thanks.
on the device the preferred network type is LTE but most of the time it falls back to HSPA mode and not LTE how do you force the LTE mode only? My location get's 3-4 bars for LTE coverage and all 5 bars for HSPA but LTE is faster
Dial *#*#4636#*#* on the keypad and under phone settings there is LTE only. Your phone won't work for calls possibly after you do this and you won't get data outside of an lte area.

Thank You. Yes it did work but changed it back since I need my cell phone to be a cell phone for calls

How do you change it back? Mine keeps reverting back to LTE only and I am unable to make and receive calls.
Did you get calling back?

man, i grepped a whole thread in relation to this very issue, it's a very imformitave read on LTE network overlays on legacy & upgrading cellular & the intro to these single chip, single pathed qualcomm snapdrgon families, but it got closed;
the nexus 5 only has one chip to handle all networking, from wifi, voice calls, to bluetooth;
it's doing quadruple duty, a question, what technology are you using, gsm, or cdma?
~edit~
nevermind it, you mentioned hspa, so it is gsm..
i'm reading up on lte to gsm handover right now.. lol

that's what i'd like to know.. lol
necro'd as in meaning; left'd to wither inthe wind, or because it's 5 months old, it's not worth posting to anymore..
that's why i asked if the issue was solved, there's threads, & posted STILL asking about LTE faulty connections scattered all over the place, so i guess the issue isn't solved in relation to this handset..
i'm in the school of thought, that like a car, or any tool one would use, it's best to grasp a critical understanding of what it's being used ON..
(am i wrong in this assessment?)
from there, once you understand the build of your tool, you compare it what it's being used on, with it's pros & cons; heighten it's pros, lessen it's cons..
wen i went to mexico just two weeks ago, i ordered two telcel prepaid sim cards to use for that 5 day stretch, i noticed i only got version 5 sim cards that didn't do lte that telcel provided, i called back & asked why, & was told that yes, telcel DID provide lte, but not in the area i was visiting, the highest i would get was hspa+, & only in mexico city & within cancun proper would lte be utilied..
knowing this, & knowing i would be off the beaten path on the beach & not in the major city, i opted for the cards sent, settling for the highest hpsa+ speeds..
maybe not all of us, but many of us, purchase our vehicles (& phones) based on critical knowledge of the phone & network in unison, **if we want more utilization from our hansets**
remember that scene - http://nilvideos.blogspot.com/2008/09/transporter-bank-robbery_17.html
I don't want to try disabling the hspa and calling without knowing I can flip it back on easily..

hey, are you on tmobile?
if so, tmobile's roaming is set within it's sim, *unless you manually select a particular nework*
"The device detects and registers on wireless networks inside T-Mobile’s calling area, but roaming networks are usually restricted to T-Mobile SIM cards. You can manually select a network only in areas where T-Mobile does not own GSM spectrum." - ~attachment~
our nexus 5s use single chip, single pathed radios, only one path is used at one time, right?
on the network side, things can be set up pretty differently -
3.3 SUBSCRIBER DATA ASPECTS: USIM/ISIM
Coexistence of LTE with WCDMA/HSPA and GSM Network requires a smooth transition of home location
register HLR towards HSS based on 3GPP specifications. This also helps in providing next generation
Data Layered Architecture that addresses operator’s needs regarding centralization of subscriber data
used for authentication across multiple layers of the same session.
The SIM/USIM is the security token in 2G/3G networks for authenticating a subscriber in the operator’s
HLR. The USIM will continue to provide user authentication function at the access level to the LTE
network.
However, it is necessary to define a mechanism for service level authentication as well, for services such
as the IMS. The ISIM (an application on the UICC) is defined to hold both the user’s access level
credentials and the IMS Private User Identity that is stored in the HSS. The ISIM enables the user to
authenticate to the LTE operator’s IMS network and access its services.
3.4 ROAMING SCENARIOS
There are two roaming scenarios based on home tunneling compared to home tunneling with the
possibility of local breakout as shown in Figure 9. The 2G/3G networks refer to legacy CS or PC based
accesses like GSM/WCDMA in the network
http://www.4gamericas.org/documents/4G_Americas_Coexistence_of_GSM_HSPA_LTE_May%202011x.pdf
to set up domestic roaming on this type of handset ACTUALLY make you roam moreso on other US networks, even though the sim card is provisioned with what network is OK'd?
we're not talking from an older, dual pathed chip paradigm, when that meant exactly *that*..
these newer phones are different beasts..

LTE has an all IP backbone, with no circuit switching mechanism, the network would provide that, & from my understanding from reading up on it, wcdma provides the **IP flattening** for voice on the gsm networks, just as ehrpd does for cdma networks..
what would happen if you switch on domestic roaming in -
APN & data settings
To set the Access Point Name (APN) and turn on data settings, follow these steps:
1.From any Home screen, tap the All appsAll Apps.pngicon.
2.Tap Settings.
3.Under 'WIRELESS & NETWORKS," tap More... to display more options.
4.Tap Mobile networks.
5.Check the Data enabled check box.
6.Check the Data roaming check box to receive data when roaming domestically
7.Uncheck the Data roaming check box when roaming internationally to avoid incurring roaming charges.
8.Tap Access Point Names
9.Choose from the following:•MetroPCS - fast.metropcs.com
•T-Mobile GPRS
•T-Mobile GPRS - fast.t-mobile.com
do you think you'd simply, roam on another provider?
i suspect it would aid your phone in it's LTE to GSM voice handling..
i suspect strongly.. setting it to *LTE* in -
Switch 2G / 4G / LTE
To change the band between 2G, 4G, and LTE, follow these steps:
1.From any Home screen, tap the All appsAll Apps.pngicon.
2.Tap Settings.
3.Under 'WIRELESS & NETWORKS," tap More... to display more options.
4.Tap Mobile networks.
5.Tap Preferred Network Selection.
6.Choose from the following:•LTE
•3G
•2G
..........................
on yet another note,, your handset may be functioning more properly than you could imagine; in your OP
"on the device the preferred network type is LTE but most of the time it falls back to HSPA mode and not LTE how do you force the LTE mode only? My location get's 3-4 bars for LTE coverage and all 5 bars for HSPA but LTE is faster"
tmobile's LTE may simply be having issues for a spell, to be worked out at a later date, & you're falling back on hspa+ asa failsafe..
you may not have to change a darn thing..
In the Palo Alto area LTE doesn't always stay on and the HSPA+ does not actually transfer any data. Sometimes hspa+ is on when weak LTE is available. In situations where I want wreak LTE over strong but useless hspa+ I need to force LTE not just prefer it

Hi everyone. Quick question. I searched but didn't find much, but I was wanting to use LTE only (*#*#4636#*#*, Phone, LTE Only), and it does work but on Sprint, it disables 1x and pretends like the phone has no coverage and then does the "Searching for Service" and the battery drains like crazy. Any ideas?

That mode disables all voice and texting abilities, I don't think you can use that on a phone, especially not a phone on Sprint.
turn it back, if the phone doesn't think it has a good enough signal to use LTE, trust it and drop to 3G you'll be better off.
Use global setting for Sprint

I don't want 3g though because my phone has the power to get a signal but if it gets down to 1 bar roughly (driving between towers and I'm in a fairly big city so it's not a coverage/reception issue) and it drops to 3g, despite the fact that it'll get stronger if it waits 5 more seconds.
you can not get/make phonecalls on lte only, period. its for data only.
indeed. setting it through the dialer to lte only, makes that lte data channel the only channel, it kills the ehrpd / 1x cdma 200 ip hand-off needed for voice paging to & from the network..
but NOW i know WHY you were forcing lte only via the dialer (didn't know at 1st)
but where you are (if you're on srpint) this is what' was reported happening -
Sprint used to have "same-as-native" 3G service in the western half of Kansas via those carriers, and even used to show it as Native on their coverage maps. Then it changed to Off-Network roaming a couple years ago. They even stopped Native service along I-70 through most of Kansas and eastern Colorado. Sounds like some of those carriers aren't being too accommodating to Sprint nowadays.

i didn't know, the hometown of sprint, was having such a hard time covering, it's own home state..

That's inaccurate for me as I'm in central KS. That only applies for west KS. I'm in a native market with LTE, NV, and band 25 and 26.

ok.. central ks..
what were your settings prior, to lte only?
Just LTE/CDMA. There are times I want to set LTE only so I don't drop 4g. Of course I have service with that setting.
Sent from my Nexus 5 using xda app-developers app
you know, that going via the keypad to set LTE only you'll kill the fall back bridge to 1xrtt voice & evdo 3g, right?
& every time you want to have voice service you'd have to do the toggle to undo LTE only , then when you want it back LTE only ..
you say "you don't want evdo 3g" but the devil in the details are, you'll not have voice service ither, that way..
is it worth that trouble?
