Android pick up 3G signal without data plan?

Hello, this sounds interesting to me. In fact, I do not have an active 3G data plan or 4G and I am currently using 2G. However, when I set the airplane mode off and the phone starts to pick up 2G signal from cell towers, it also pick up the 3G signal too. In fact, I can see on the signal strength bar a 3G or H+ icon that are constantly changing with some up and down arrow signs that indicate that my phone might be downloading and uploading data. Can anyone explains this phenomenon? For sure, I can not access to the Internet without Wifi.

go to settings-mobile networks and there will be option for mode
if the mode selected if gsm/wcdma - then ur phone will pick up 3g signal if it's available in the area irrespective of ur plan..this means ur carrier has activated 3g services..u can deactivate by selecting mode: gsm only!(2g mode)
wcdma mode is 3g only!
hope this is helped!

If you truly can't have 3g on your plan, phones will communicate with towers due to the requirements to have a phone be able to call 911 even if it is not activated at all.

this has happened to me before as well

Maybe it's just scanning the available networks or something? Do you have data connection disabled at your device?

What is this thing about a 3G data plan?
A data plan is a data plan. Your speed depends on your phone hardware and what your provider had installed in your area...
At least that's how it works here in Norway, they can and do limit our download speeds after a certain amount of data is transferred as I assume they do elsewhere, but even when I pass that threshold my phone reports using 3G...

the situation is not same everywhere...
like in India and more countries, 2g and 3g services have different rates and are users can opt whether they want a 3g plan or 2g plan....although speed is more in 3g!

T-Mobile no LTE

I had trouble activating my SIM earlier. It did not want to activate when i did initial set up on the device. So I skipped thinking that i can activate it after set up. So for about an hour it would not connect to T-Mobiles network, then it finally did, with bad signal. All i am able to get is mainly 3G and H data signal, no LTE/4G like i am paying for.
has anyone had a similar problem before? Do you think this can be a bad SIM? Any help is appreciated.

Sorry to hear about your problem my phone isn't here yet so I can not give insights yet but will let you know if anything arises

Getting the same problem here, not getting LTE only H... this is my first time with a LTE phone so maybe my area doesn't have LTE, going to Uni tmrw and see if i get LTE there (which is should)
I like in Central Jersey so don't know if they have LTE there, i am pretty sure they have it in Northern Jersey, specially the Newark, Jersey City, NYC area's

U have lte in your area?

Try setting your APN to fast.t-mobile.com instead of epc.t-mobile.com

Yes. You can do a zip code search on there coverage. My zip is 37075 its got great coverage. I feel its a SIM problem.

T-Mobile does NOT have nationwide LTE so theres no guarantee that you actually have LTE where you are. Best to make sure of that before you do anything else.
And just so you know, their coverage site does not distinguish between LTE and HSPA+ since they consider both 4G.

No LTE here on a new T-Mobile account. My roommate has it on his S4. I'm hoping it just takes time to provision. Using fast.t-mobile.com

i get lte anywhere i go..im in miami

LTE is not a huge deal as long as I get HSPA+ its fast where I am. It shows Excellent coverage in my area, so yes I may not get Real LTE, but i should get good HSPA+ and cell service. Right?

Try setting the preferred network to LTE. No clue if this will work on a Nexus 5, but it works on a Nexus 4. Even with the appropriate hacks, I only get LTE in my area when I do the following.
1. Enter *#*#4636#*#* in the dialer
2. Go to "Phone information"
3. Change the "Set preferred network type:" dropdown to "LTE only".

LTE started working after about 4 hours after setting up my new T-Mobile account.

I live in Nashville, well the outskirts. I may not have LTE but the HSPA+ should be decent. Like I said above it may be my house. I get crap wifi reception in here so thats probably the reason.

Yep. Thats why you got LTE. Still Rolling out in my area. I am actually not upset about it. The HSPA+ is pretty dang good.

I've been in LTE since I turned on my phone. I'm in Connecticut

My N5 flips between HSPA+ and LTE pretty much without rhyme or reason. Interestingly, HSPA+ is about as fast down most of the time, but of course LTE is faster uploading.

How do you force LTE mode and not HSPA?

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.

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

LTE Only Searching For Service Battery?

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
Sent from my Nexus 5

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..

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?

Airave, CDMA and LTE

I just got the Airave and I was wondering how come when I use CDMA only for "mobile networks", I get 5-6 bars i.e. pretty much perfect but when I select CDMA/LTE, I get 1 bar..sometimes two.
More importantly, Airave hasn't fixed this issue but when I go to CDMA only, it seems perfect. How do I go about fixing this?
Thanks
PS - It seems like at home, I have weak LTE (which is what it's connected to by default) rather than holding onto a STRONG 3G signal....how do I make the S5 favor strong 3G over weak LTE?

Which kills more? 3G at -70db or LTE at -102db?

The Airave is only a 3g CDMA over Broadband solution. When you choose CDMA only it's the only choice and is a strong connection. With LTE enabled the device is still trying to keep an LTE link but since your coverage area sucks it keeps falling off. Seems the Sprint GS5 has that issue for everyone where there is bad LTE coverage. It may also be that "Connections Optimizer" crap.
I'd suggest tasker or a similar app for automating setting your mobile network to CDMA Only when at home or elsewhere LTE is crappy and creating another to revert back to LTE/CDMA. There a bunch of threads with people trying to figure out how to optimize their LTE band for their specific coverage. I burned a lot of battery with my N4 constantly trying to decide whether to stick with HSPA+ or other crappy alternative networks. I don't think Google or the manufacturers have done a good job of considering what happens under less than good conditions signal wise.

It's not so much that it falls off but that the signal for LTE is low....around -112db while CDMA/3G is around -70db (full bards).
I wish there was a way to make "CDMA only" turn on at my house while LTE/4G turning on while I leave it....How do I do this using tasker or a similar app?
Then again, I don't really download anything outside of my house....only time I use data outside my house is for Waze or Snapchat or Instagram or Facebook....and they seem to load fine under 3G...it's not worth the battery drain to use 4G for those applications.

The Galaxy S5 only has one radio so this causes huge problems with use of a device like an Airwave. Since Sprint didn't include WiFi calling in the S5 you have no real solution except to force the S5 in to CDMA only mode. It requires a reboot and is annoying. This is ridiculous by Sprint. I went and got a more advanced phone with two radios (The Galaxy S4) and now have no problems with one radio staying attached to 1x Airwave and LTE. I returned my S5 and am now very happy.

With Tasker or similar you'd want to set it up to switch mobile networks to LTE/CDMA based on your location but like rocket said it's a reboot every time - aka PITA. I just set up a shortcut to Mobile Networks and change if it's a problem. Rebooting often sucks. I don't know why they'd give the S4 two radios and the S5 one. Seems stupid. I'm not sure if you can change to CDMA only via the debugging options - that may not require a reboot. There's a big thread about optimizing LTE bands that has a bunch of info on that.

Alrighty. Looks like I'll use CDMA at my house for Airave with Wi-Fi for downloading stuff and have CDMA for downloading stuff while I'm beyond the borders of my house.
I don't "download" anything anyway.

You will be UNABLE TO CONNECT TO THE AIRAVE unless your are in "CDMA ONLY".
Go to
settings/network connections/more networks/mobile networks
and change to CDMA .
( Do NOT select CDMA/LTE until you LEAVE the Airave vicinity)
If you are indeed connected to the Airave, you will hear a recording telling you that you are if you call *99.
You will have to re-enable the CDMA/LTE everytime you leave the vicinity of the Airave to get LTE service.
Sprint Tier II Tech informed be of the above, and I have verified it all by personally testing the above.
Now, here is the real question:
What are the EXACT DIFFERENCES between using the "Wi-Fi Calling Feature" with NO Airave - AND- using the Airave WITHOUT using W-Fi Calling.????

the differnece is the range of the signal / router range of 2.4 ghz/5.0 vs airave 5k to 6k sq ft. and of course haveing a phone made before the s5. any lte+ or sprint spark device will not stay connected to an airave device without network mode selection and crossed fingers. and due to that- wifi calling was born and pushed to the front lines

When you're at home, why not just leave WiFi on for data, and WiFi Calling on for phone calls? That's what I do. I used to use an Airave, but I stopped using my Airave when I got a Galaxy S5 because it has WiFi Calling. (BTW. If you leave WiFi Calling on, your phone will automatically switch to cellular calling when you leave the house.)
