I have n9005 rooted TouchWiz stock on 5.0,
when my phone is on LTE mode i'am unable to make/receive calls.
Kindly help me solve this problem.
Is the phone set to LTE only? If it is, does the carrier support VoLTE?

LTE/4G is a Data-Only network. To make calls over it your carrier needs to support Voice Over LTE, or VoLTE for short. Which is the mobile equivalent of VoIP.\
If your carrier does not support VoLTE, and your device is only allowed to access LTE, you can't make calls. Change to 'LTE/WCDMA (Auto)' (4G/3G) or 'LTE/WCDMA/GSM (Auto)' (4G/3G/2G) mode so the phone can automatically change to a network that supports voice codecs.

How about switching to wcdma/gsm or wcdma only?

Something appears to be preventing the automatic switch from LTE to 3G/2G. Did you do something in the Servce menu?

My device didn't had the LTE option first so i did something which i don't remember now, what it was, i did it when i never used LTE, but as now i'm using LTE and came accross this problem. also i have installed a network type toggle app.
Sorry for being such a nub but where do I go to change the mode? Option > network operation? Thanks

Not receiving incoming calls on AIRTEL 4G LTE
Iam facing peculiar problem with the phone. Need help with the problem.
I am using samsung note 3 LTE. When ever some one tries to call me, my mobile is Not reachable or out of coverage area even when my mobile is in my hand , perfectly working with the second sim. outgoing calls are working fine. Again, when I am in call, then if any one tries calling me, then I get call waiting. So incoming call waiting is working for me. But incoming calls are not able to connect. LTE data is working fine though incoming calls are not working.
Tried the following but no luck. Problem still persists:
1. Reset phone and erase all data
2. Hard reset phone (volume down + poweroff and clear all data in drive)
3. Tried changing SIM to second slot
When I switch the sim back to 3G mode or 2g mode , incoming calls are working perfectly fine . I googled it and found that most people had same issue and was resolved on switching back to 3G or 2g .
But I need to use 4g . Please tell me a solution.
I had that same issue until I took my note 3 to Rogers and they said that the note 3 doesn't support Lte
Your rom must support VoLTE.
I would unroot and go back to stock firmware, and see if problem still happens,? if it does ,its most likely the sim card.sd card reader slot, (flex cable),my Galaxy s4 had the similar symptoms , but LTE would work with a custom rom, but not if I used stock firmware, replacing sim card reader flex , just google your mak and model and search ebay. mine cost a few pounds for a decent quality part, so dont go rushing to buy the cheapest. No problems since replacing that part, even after resetting phone 3 times to see if it was a fluke. I know its a bit late for a reply, but this actually worked , I am 99% sure it would work for anyone else who has this problem with lte not connecting when 3G, and 2g do connect. If you have tried swapping sim cards, putting sim in another phone,, etc,etc. this part mentioned(sim card/sd card reader) is your culprit. Took me just over 5 hours of testing to find the solution. thanks and fair well android users

For many people having issues with LTE not connecting and diverting to voicemail on android, I am here to offer a solution to your woes. I have a Samsung Galaxy S4, GT-I9505, and recently in in 2018 in July, I had the same problem, phone calls connected on Gsm, Wdcma, BUT when I tried LTe mode, NOTHING, WENT STRAIGHT TO VOICEMAIL.Anyway I tried almost everything mentioned on certain websites and forums, with some luck, Changing LTE mode to GSM worked, and I could receive and hear phone calls. So I investigated further, I tried re flashing stock firmware, factory resetting phone.(nothing worked). I then rooted my phone and flashed a custom rom (do not try this) as it could damage your device if flashed wrongly. Yeah, so I flashed a custom rom, and low and behold problem disappeared, so I used my phone on LTE for 2 days, with no problems, I then decided to go bacjk to stock firmware, ...problem came back, not connecting to LTE mode..........being as patient as I can be, never gave up, and had a spare phone which was dead, just laying in the drawer, ..so ,I took phone apart and thought, it must be where simcard contact make contact with sim card reader contacts ( broken sim card /sd card reader part, and was I wrong, no, it actually was the sim card reader part which coonects with th motherboard, Voila, I am 99% sure if anyone else has this problem with any android that has LTE capabilities, and you know its not the sim card, then try this fix first, MAKING SURE YOU GET SOMEONE YOU KNOW TO HELP YOU , IF YOU ARE UNSURE OF WHERE TO BUY AD HOW TO FIT. hope this has helped,and I know it is a long thread, but hopefully it will be a solution that works for whoever reads and trie this, over and out. yours in sincerity, Tech82, from Surrey, England.

Greetings fellow telephony addicts - purchased a Boost Mobile Moto E w/5.1 (xt1526) because of apparent ease of ul'ing bl and rooting. True enough --
However since then I've been trying to get the device to allow use of a GSM SIM (USA/att.) Recently did it on a vzw (xt1528) no problem following instructions found here bit the xt1526 has beaten me senseless, going so far as to install cm13 in a totally illogical move. It works beautifuly, if you don't need calls or mms. Searched the crap out of the E forums with a couple of tips that did not pan out.
Anyone give me any hints /tips or even a nay as in "you dummy you can't to that!"

Boost / sprint xt1526 are locked so that us domestic GSM Sims are not recognized. To my knowledge, no one here has yet gotten around this. I switched from a sprint branded one to a USCellular, which is fully SIM unlocked out of the box, bootloader unlockable, and supports att LTE. Using it right now with my postpaid ATT SIM

Only thing I can think of is to flash the RADIO from a variant that isn't SIM locked and seeing if that works. It's a risky experiment tho... it could definitely brick the device in terms of ever being able to connect to a cell tower again.
Closest match is the USC 5.1 stock ROM's radio, which has the same model number XT1526, and is CDMA compatible, but that phone is also known to work on domestic GSM networks.
Double Thanks - Phone is useless to me as is so it's worth a go. Will report the results here.

Weird - I installed the complete USC 5.1 stock ROM - Everything seems to work fine, but the system version and the broadband version coming up as Sprint. US cellular is not a Sprint MVNO I don't think, but it seems to be kind of a hybrid in terms of networks? No option for switching the network to GSM/LTE in the settings that I can find.
Not sure what I'm going to try next...

Did you flash the Radio/Modem too? If not, that's why the baseband comes up as Sprint.
Dial *#*#4636#*#*, phone info, change "CDMA/LTE" to "LTE/GSM/CDMA auto (PRL)". If you can't do that, follow the 5.1 instructions here: http://forum.xda-developers.com/moto-e-2015/general/how-to-verizon-moto-e-2015-gsm-network-t3098953 (change the 9 to a 10 for LTE/GSM/CDMA)
This will allow you to change the phone to LTE/GSM/CDMA mode.
Isn't the NON-HLOS.bin file the modem file? I did the keyboard commands and got the phone info and was able to change it but it didn't change anything, live or after a reboot - same thing. did the adb shell commands and the same
thing, cellular network settings grayed out. I put back the sprint SIM that came with the kit and it was fine and the network settings are available...hmmmm.
I greatly appreciate the suggestions. I'm gonna leave the battlefield and get dinner or my wife will call me mean geeky names

Putting this thread to rest
Spent the last couple of days flashing the E with rom after rom, particularly of GSM phones, ATT, TM, etc and their respective radio files. And not to my surprise the phone works fine with every one of then regardless of model XTxxxx anything, phone runs flawless, except for the network of course, which always remains Sprint.
I have to conclude, unless someone can prove otherwise, that the phone network part is either embedded in the chipset as hardware or a combination of hardware and software, or the modem files are somehow protected from being overwritten.
Was interesting and educational.
Thanks to those who gave ideas or suggestions, especially you Mr. President

Ok –*question. If I put Cyanogenmod 13 (Lollipop) onto the Moto E 1526 (U.S. Cellular version) –*will GSM work on it? I need to buy my grandma a GSM phone who doesn't live in the States & I want the GSM card to be easy plug in play for her.
I know that the U.S. Cellular version is the best because it is unlocked for GSM as well, but I believe XT1526's default radio is CDMA.
Maybe I should get a GSM sim card here in the States and switch it to GSM on CM13 (if this is possible) –*that way all my grandmother has to do is put the sim card in without any hassle.

The device does do funky things with the radio on first boot on a new rom. I've run several CM based marshmallow roms. There's no real issue, but you need to go through the non-adb method (using the network app) to get GSM working on every new clean flash. Typically this means pulling the GSM SIM before initial boot (when I don't, the radio keeps cycling through modes making initial setup very difficult), do setup on Wi-Fi, turn off radio, insert SIM, then do the process.
I definitely would not give the device to a non tech savvy person before doing this on a clean flash. Once it's done, you can remove and reinsert Sims without issue.

Yep, you got it. Actually, I don't think it's too picky about the order of operations as described in that thread - I've done this many times without referring to the thread so have likely done it "wrong" at times, and it still works. Basically, radio off (either via airplane mode or network app), switch modes, radio back on.
Just don't clean flash a rom without either access to Wi-Fi, or a locally installable copy of the network app.

Hey .. i am in Karachi Pakistan ...
i have seen this phone workingperfectly with gsm network until someone makes a factory Data reset ..
still not found out the solution ..
the devices arrived from china in working condition ..
FYI - US Cellular was bought out by sprint last year, so they are now a sprint mvno.
Did you try flashing the stock 6.0 ROM?
Hi all,
I have the dual sim S7 SM-G935FD running the XSP firmware. Rooted with the microSD Mod on Sim 2. It's being used in the USA at the moment. Sim 1 is AT&T and Sim 2 is T-Mobile. Both are USA sim cards. Everything goes through Sim 1 AT&T - Voice, Text and Data. Sim 2 is just for receiving calls only. Sim 1 is set at LTE/3G/2G and Sim 2 is 2G only.
Since day one I have this connectivity issue pertaining to data connection.
When Sim 2 gets a weak signal and eventually drops out, data connection on Sim 1 remains - everything works. However, when Sim 2 is picking up signal again, the data connection on Sim 1 drops out.
When this happens, the pull down notification will display that the data connection is on Sim 2 - as if the phone switches the data connection from Sim 1 to Sim 2 by itself. However, if I go to the Sim Manager, it will show that the data connection is still on Sim 1 like it originally was. At this point, the phone has no data. And yes, the phone is displaying conflicting information. Notification says Data is on Sim 2 but Sim Manager says Data is on Sim 1.
To fix this, I have to use the Sim Manager, select Sim 2 for Data. Wait a few minutes. Then, choose Sim 1 for Data again, then everything comes back normal. Data connects.
This is quite annoying in a poor reception area.
Troubleshooting steps that I have tried but they do not fix the problem-
Flash stock firmware no root
Use a different stock firmware - XEU
2 sim cards only with no microSD card on the back of Sim 2
Choose 3G/2G only for Sim 1 and 2G for Sim 2
Swapping Sim 1 and Sim 2
If I disable Sim 2 the problem goes away, but of course, what's the point of dual sim then?
I also have a S6 Edge+ Duos SM-G9287 but it does not have this problem.
Any ideas? Thanks.
Just wanted to add that I am experiencing this as well.
Man this is getting unbearable. Is there a specific forum for the FD devices? I'm thinking I might just return this phone while I still can.
Wow I was going to put something on boards as well with literally the exact same setup in USA. It gets way annoying when tmobile gets weak and switches even though I have it set on sim 1 data. I really hope there is a fix or else I might make the switch to htc10 (if they even get a dual sim) and keep my fingers crossed it works better. My S6 duos works better than this but I don't have additional memory with hybrid SD sim card on s7.

FYI -
I have been running XSG firmware. I just upgraded from APC8 to APD1 and the problem still remains.
Just trying to save some time for those of you who thinks upgrading will resolve the issue... it will not.
It is amazing how the S6 Edge+ Duos does not have this problem. Things went backwards for Samsung.
No problems here though mine is the G9250 dual sim version (HK).
G9250 is s6 edge is it not? We are on g935FD. It seems like I can never find the elusive perfect dual sim! Always some kind of bug! Might be heading back to my Xperia z5 premium. Can you guys confirm that it's wifi causing it? Seems like whenever I come off of a wifi network it never picks mobile data back up.
That seems like part of the problem too..as soon as wifi loses connection then it switches and then no more data

Has anyone fixed this? I have tried to flash a couple different modem firmwares to no avail. The T-mobile one won't flash as it uses a snapdragon chipset.
Mine was doing fine until I did a firmware update and now the data connection problem appeared. I was on a B6 firmware with a B9 modem on a AFG CSC so I will try to go back to this and report back whether the issue resolves. Any firmware starting D1 (tried D3, D6 and D8) causes the data connection lost issue. Even just going back to a B9 modem with the D8 firmware didn't help. What a pain in the rear...
Follow up to my previous post:
Officially, G935FD is a piece of crap. Tried every combination of modem/AP to get this work but no luck. Resorted to single sim mode for now.
I have this same issue. the only way it works is to manually select one sim in use at a time. I just removed the second sim and added a micro sd card for now.

Did you update your firmware to a different CSC? That's when my issues started (went from AFG to BTU and even after going back the problem wasn't fixed)
What is your original CSC?

Mine didn't work out of the box with stock firmware. I have since upgraded the stock firmware but haven't tried using two SIMs with the latest update. Maybe I'll test it over the weekend.
+1 on this bug existing for me since day one. I have been sticking it out and staying with dual sim as I don't have any other option. Kinda wishing I had just returned it... I have gone through hell trying to talk with people in India (where the phone is apparently from) about just getting the bug's existence up the chain. If only we could get a dev to take a look at our logs so I can have a reason to just root the damn thing already. Has anyone tried maybe flashing the sim manager apk from the s6 edge? Is there even a sim manager apk?
I have exact same problem with S6 edge+ dual sims. SM-G9287. Problem started since marshmallow updated. Didn't have this problem before under old android version. Has anybody found any fix yet? Right now, If I disable one of the sim, then it seems ok, but I need both sim to be on to receive call on either number.
My phone was stock firmware. Problem seems to be with Marshmallow 6.0.1 , not because of custom firmware.

Kind of same problem here, but it happens only since I received the update to APD1.
I live on a border zone, so I have to force my LTE sim card to its own network. The second SIM is only on 2G.
When the phone loses its own network, SIM with LTE completely disappears, everything is moved to SIM 2G and of course I lose network. The problem is that the SIM with LTE is not seen anymore, even if I go back where the signal is, and the "mobile networks" option disappears in the Settings. I cannot do anything else the reboot the phone to see the SIM again.

I have similar issues with my s7 duos not the edge model. Sim1 tmobile, sim2 at&t. Sim2 seems to be the issue for me. Cell quality at my house is not great. I also have a xperia z5 premium dual that has similar problems mainly with lte. The samsung does hold lte signal but the bars are misleading. But the samsung, I woke up this morning and sim2 was offline no calls or text or data. Call quality with sim2 isnt as good either. I blame cell signal on that since the sony has similar issues. But I have seen it with sim1 set to calls and texts and sim2 for data the pull down says sim1 even though sim manager says sim2 is data. Wtf right? Disabling sim2 and reenabling gets it back working again but what happens when the phone does this is you lose data since sim1 data would be gsm only. The common theme is sim2? Also seems signal quality is a big factor. My CSC code is ECT which is Nigeria. I have not changed firmware yet other than the APD1 update. Ironically my xperia z5 dual didnt have these issues at all with lollipop the problems started with marshmallow. I am in the US by the way.
Temporary fix?
Looks like I accidentally ran into a temporary fix, that's working for me for the last few days. I'm on Vodafone for SIM1 and T-Mobile for SIM2, EU&US.
When I restart the phone and set SIM1 for data on LTE/3G/2G it connects, but looses the connection after a while and defaults to SIM2 (with no data). No BT, no WIFI, no data icon anywhere the screen.
When this happened, I ejected the SIM card holder and pushed it back in 2 seconds. Suddenly SIM1 was trying again to connect and the 4G icon appeared. At his point I turned on WIFI.
The weird stage: WIFI on, 4G icon flashing every 5secs – but it's working as it should. If I loose reception, it does not switch cards. Actually never switches card if I don't want to. I can live with the flashing 4G until we have an official fix.
Let me know if it works for you guys!
Im learning that mine is a lot more stable if I set everything to the same sim and not split up talk/text on sim1 and data only on sim2 like I was doing. Not sure if this is placebo for now but I have everything set to sim2 and so far so good with no drops.
Hi, i recently buy an used nexus 4 in ebay, simply for nostalgia, so, i´m in Mexico, the nexus 4 that i had 3 year ago, was unlocked, so, i supose this too, when arrive, i connect to wifi immediately without any sim inside, the cellphone request for one upgrade, i accept, after that, i put my sim from Virgin Mobile and the nexus only showed " no simcard inside, only emergency calls.... y try with other carrier, weex mexico (virgin and weex work in Movistar, they are OMV) and the same all.... finally y put a sim from at&t mexico, nothing... with the sim (att) inside, i downgrade to android 4.4.4, when woke up, the nexus 4 with the same result, No simcard, so, the cellphone wasn´t detecting any simcard, after that, it request for the next upgrade, lollipop 5.0.1 that i accept, but in this chance, the nexus with the simcard from ATT showing signal¡¡¡¡¡ the cellphone was working at 100%, i made a couple calls, without problems.
But, i try with the other 2 simcards, and it doesnt detecting, simply show again No simcard, emergency only, so i switch back my Att sim and this is detecting without problems....
I install a rom named Pure Nexus, waiting for work, but the same, only with ATT simcard work, so i downgrade again to 4.4.4 but in this chance with other simcard differnt from AT&T, Virgin mobile.... but nothing, nexus 4 is not detecting any other simcard than at&t¡¡¡¡¡¡
What can i try? could be a nexus 4 locked only for one carrier or what? in google dont appear in blacklist, the imei is good nor corrupted... could be the sim holding?
try going back to stock using the nexus 4 toolkit,then root, and try one of the hybrid models LTE enabler or download the 107-3, if that doesnt work also, then it might be defective.

use this to go back to stock

you will get android 5.1.1, you can also install custom recovery and root using it.
then if the sims doesnt work, change the modem using the LTE Enabler you can get it from the Play Store.
it has the modem until version 104-33, but im using another one the 107-33 that i got from

104 33 and 107 33 are hybrid modems, but you can also install stock modems,
the modem is the one that allows you to make calls and use the data channel in your phone
hope that makes sense, let me know how it goes. regards.

well, i flash EnableNexus4LTE.zip and LTEhybrid33-84 without good news, i have the same issue, only at&t mexico sim is detected and the others no, well, i´m now with 4G LTE but only working in at&t
i don´t know what other things trying in the nexus, seem like only prefer at&t sim and no one else.
Adding information, i have sims from cricket USA and t-mobile USA, i know is not supported in México, but it will be for try to get something like: Sim not activated... or invalid sim, but other different from my nightmare: NO sim, please insert....
SOLVE:
I´ll auto answer... after a lot off attempts, i found the problem is the sim reader, like i posted before, only working with at&t Mexico sim, so, I watch the thickness of this was little bit smaller than others, my "strategy" was try to imitate the fact that at&t sim is making contact gently on pins, i take a 3in1 simcard, and i put the nano sim in micro sim adapter (included in the sim) but not in all (i don know exactly the words in english), so by this waya the nano sim standing on a little bit from microsim adapter.
when i insert the sim by this way an my nexus, and turn on, the cellphone recognize inmediatly the sim, so i found the key of this problem, like i said, the problem here is the sim reader, because, a normal and good sim reader not need this tricks to get signal.......

I glad its working now, you can stay on 5.1.1 with the hybrid modem if you got the 4G signal, or return to 4.4.4 if you want. regards.

i think is real, speedtest results are much better using 4G. I got around 40mbps.

i just sintall LTEhybrid33-84 and EnableNexus4LTE with TWRP custome recovery, but apparently without any 4G signal, in the menu mobile networks only i can choose 2G & 3G.... but the baseband does change.....
so, i use the trick hidden menu with *#*#4636#*#* and i choose LTE only, only with this my nexus 4 has 4G signal¡¡¡¡¡¡ but, if i come back to mobile networks, again only i can see 2g and 3g and the little 4G on top disappear.... so i need to come back again to hidden menu....
conclusion, mobile networks menu it will prohibited for me :silly:

you should be able to select "LTE/GSM Auto" that way the phone will switch to GSM when needed.
and the option is only visible under *#*#4636#*#* menu, also, we have to switch to LTE/GSM auto, if the phone is restarted. there is a way to make it persistent, but I haven't tried. i'm fine with it since i don't restart the phone too often.
hope this helps, regards.
Hi, ive been an owner of an HTC bolt for a while now. Recently my island was hit by the famous Hurricane Irma (Puerto Rico, USA Territory). And ever since my mobile data dont want to connect.
Details about the phone:
HTC Bolt (Sprint but is GSM Unlocked and have been using it with H2O Company. Uses At&t Towers.)
Phone is bootloader unlocked and rooted but stock software i believe is the march latest update (1.32.651.6)
The phone was working excellent by that day. Now i had to switch to my spare phone HTC M9 and mobile data works fine here.
Rightnow i still dont have electricity at home. But i was wondering if any of you guys have had this same issue or maybe know why this could happen.
Ive tried resetting network settings, checked the APN multiple times. And no luck. Also i have access to the DM menu where i can see all the network settings when i input the MSL code. But everything seems fine.
Maybe running an RUU on it can fix the problem...
Thanks in advance for any help you can give me.
Willing to bet it is more of a provider issue. Give it some time for them to fix the infrastructure

Thanks for the reply!
I thought of that but in that case my M9 shouldn't be working either. And its perfectly working. Don't know maybe is the LTE band it is trying to connect is bad or something. Because on the M9(Factory Unlocked version) the data is working but not as fast as always.
Oh yeah not really sure sorry.

this thing is driving me crazy. I'm on the line to Customer Service to see if they can find the issue.
But me guessing, does the radio image installed on the phone has anything to do with that? Does that file or part of the ROM could get scrambled and cause this kind of issue??
Update:
They have reset the account, but they say is the phone thats giving me the issue, since the SIM card shows successful connection on another phone. I will try to run the RUU on this and see...
Ok so apparently the issue is on the network. I just tried my sister SIM card from T-Mobile and the phone connects perfectly to internet. So apparently the issue is maybe a technical problem on the network band the carrier is transmitting. And that band isn't available or not accepted on the Bolt cuz is a Sprint variant.
Don't know 100% sure but apparently that's the issue. I checked on the M9 what bands are the phone connecting and according to LTE Discovery App the phone is connecting to band 17 or band 4.
BTW
Is there a way to edit network bands on a phone?
