Hi,
My device is LG L5-E615 unlocked.
I've put 2 different operators sim cards into the device. The first slot sim is WCDMA and the second slot is normal GSM.
When I enable both slots, from time to time(like 10 minutes to 1 hour), the connection of the GSM sim card goes away and it says "No Service" and after a few minutes (2 or 3 minutes), the signal comes back. I'm not on the move and I have strong signal.
When I use 2 GSM sims, such problem does not happen. It only happens when one sim card is WCDMA and the other is GSM.
I've changed the slots (First WCDMA, Second GSM / First GSM, Second WCDMA), but it doesn't help.
Does anyone else have such problem? Any idea how can I track the issue and solve it?
Thanks

This is a known issue of the stock rom. Using two WCDMA enabled sims solves the problem. I doubt if any of the custom ROMs, of which there aren' that many yet, will solve this issue.
Note that while using two WCDMA sims, it is not possible to use 3G on both the simcards, one will always run in GSM mode only.

Hi there, thanks for this info. I currently have two sims,a 3 SIM and a Samba (internet only) sim that runs on the 3 network. My phone has the standard one sim slot GSM and other WCDMA.
I first tried my 3 SIM by itself in both the GSM and WCDMA slot and to my surprise it worked in both (in terms of 2G services). I thought that a 3 sim couldn't work in a GSM (2G) slot ? So I decided to leave the 3 sim in the GSM slot and then added the Samba sim into the WCDMA slot. However, when I turned the phone back on it connected to the Samba sim but the 3 sim said no network was available.
Any idea why this is ? Sorry if this has been asked before but I haven't been able to find an adequate explanation !
Hi i have a Notes 2 but i can only connect to Edge network not 3G even though my phone supports LTE.
My sim card and network is ok because i used the same SIM card in another 4G phone i can connect to 3G. So i suspect maybe is the phone issue or some settings i have misconfigured.
Android is running on 4.3.
Could someone help?
Thank you.
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
Hi all,
I have a redmi 3s, i have a major issue with this phone with one sim configuration
Signals drops from 4g/3g to 2g (edge) with minimal drop of signal. With other mobiles no drop of signal, stay at 4g/3g continuously. Then the mobile takes forever to recover from 2g to 3g/4g at a full coverage of 3g/4g. The configuration at the mobile is preferred LTE. I have tried with other mobiles and the coverage it is fine. With other sim providers and I have same problem.
I am looking for any trick for fix the network mode. I have tried different programs from google play and modifying the build.pro, exposed but the networks mode comeback if you reset the phone or change from air plane mode.
Any ideas?
Thanks and regards
Fix for MIUI 8
Look here or here
Different issue. it is described here:
http://en.miui.com/thread-320293-1-1.html
The workaround is to enable GPS (for example open Maps), the phone will return to 3G.
Turns out, I'm not the only one facing this problem. From the above post, having 2 SIM card active will fix this problem. Too bad I don't have second SIM.

Hello,
I have the following problem: I can't get a 4G signal with my provider.
Vodafone Netherlands uses 800, 1800, 2600 MHz for 4G connection.
I have bought my telephone at flosmall . com
It should work, or do I forget something?
Can somebody explain this?
I had the same.
I tried some 4g signals apps to check my connection. This one seemed to fix it: https://play.google.com/store/apps/details?id=com.mcstealthapps3.networksignalsearch
Let me know if it worked for you!
I have trieded with the app but nothing changed.
But still on 3G...
I need to ask this.
Is your SIM card even 4G capable? If its older than 3-4 years it might not be.
I don't know anything about vodafone, but try googling, for one of my providers I actually needed to activate 4G on their website after logging in to my account.
Also. Settings -> Dual SIM & mobile networks. Is network mode set to 4G priority and Celluar data to correct SIM card if you are using dual setup.
Yes the sim card is capable with 4G (was using it on Lumia 950XL).
Have contacted Vodafone about the problem.
But the will only support devices that Vodafone Netherlands will be sell.
Have tried to flash lineage rom, but nothing change about the signal.
(stock Rom was from groschopp)
I also have a Le Pro 3 (x720) on the same network in the Netherlands and I have no issues with 4g.
I am currently using the Grossoshop-Rom (Build-number WAXCNFN5902011181S).
You can download several signal apps in the play-store to see if Band 20 is available to you, this is the one used in my region for 4g Vodafone.
I assume you set the preferred network type to 4G?
It's working now
Have called Vodafone again for some extra information about the frequency band for 4G.
But nobody could help me, there was one person that say i can give you a other simcard type maybe it will help. (I say how will it help if 4G works on a other phone with the same sim card, but let's just test it)
Afterwards the call, visited the shop for a other sim card
Doing the sim in slot 1 nothing changed, same 3G signal.
Was thinking this the last try and do the sim card in slot 2 and after 10 minutes i have LTE signal.
Trying slot 1 again but only 3G. changed back to slot 2 and solved.
Have earlier check slot 2 with me "older" sim card and only 3G was showing up.
I have noticed stock ROMs have better signals than say CM

You need to enter the APN settings for your provider's data coverage in the Mobile data section of Settings.

Are you on a custom ROM? Maybe it did something to the modem. If so, you need to return to a stock ROM and try.
The phone has all the bands it needs to work on your carrier, and my carrier as well. My SIM already had the APN settings for my carrier on it, and I connected to LTE right away on my x722. I'm on a vendor ROM, which is pretty much just stock eUI. I can't fathom why it doesn't work for you if you're still on stock. Have you tried the SIM in other phones?
I also have this problem in Romania with my LeECO Le Pro3, but with Orange 800,1800 and 2600Mhz. The only solution for this problem was to manualy search and select the 4G operator network. Although in settings/network operator it was on 4G/3G/2G(Auto) by default, my phone was stuck in H+/H/3G until i manualy search and select 4G. If you are sure your SIM is 4G and you have the corect APN you can try this but you will have to search and select for several times manualy to work. I find this solution very uncomfortable because every time you restart your phone or put it in airplain mode, you will have to repeat manual searches and register in 4G.
my x720 doesn't have the correct bands active. i activated them with qpst but only actived and running in sim2 (sim 1 actived but no gain lte signal)
ah! i'm on 20s
