My Note 4 does not allow to latch to 2g network when 3g is available.So I changed the settings in device info *#*#4636#*#* accessed via Advanced Signal Status. The problem is that i am no longer able to switch to hspa/3g preferred,/LTE/GSM auto back and even edge does not work when data is enabled for operator1 and 2 ON SIM1 .Data works when switching to SIM2 for operator 1,2 or 3.The problem is on two different 3g enabled sims of airtel and bsnl (already checked the sims on other phone). While 3g hspa works without any problems with a different hspa aircel sim(operator 3). This makes me believe the modem sim1 has not lost functionality to use hspa/edge.
Tried -
1.Clearing cache and data of several different system apps related to settings and network but nothing happened.
2.Factory reset
3.Kitkat 4.4.4 Rom flash via odin.
4.Lollipop 5.0.2 Rom flash via odin.
After Googling a lot : I think the problem is : the phone is not able to connect (establish a data connection ) on hspa so reverts back to UMTS for Operator 1&2 (BSNL & Airtel) . As far as i know UMTS does not allow data connection. I cannot understand why hspa/hspa+ still works for operator 3 (Aircel) . When i changed my settings from WCDMA Preferred to GSM only i was on operator 1 (BSNL) . When i tried reverting back to WCDMA preferred it switches momentarily to HSPA then tries to establish a data connection and reverts back to UMTS. Same behaviour is for operator 2 (Airtel). Both operator 1 &2 works with GPRS on SIM2 and EDGE (when change to GSM only with Advance Signal Status) on SIM1 . When not in "GSM only" mode it locks to UMTS and no data connection is established.
SAME BEHAVIOUR IS ON LOLLIPOP EXCEPT

First of all, if you haven't done it already, put the "gsm/wcdma" (or something similar, it has to have both of them anyway) setting on mobile networks. If you still can't get 3g, try searching for all available mobile networks. When the search ends, select a 3g network according to your carrier (e.g. vodafone 3g if your sim is vodafone).
i think the problem is with with band.in phone description it sais GSM 850/900/1800/1900MHz(2G) - WCDMA 850/2100MHz(3G),but in mtk engineer i can't select wcdma 900 and wcdma 2100 doesn't apear(band for 3g for vodafone) so i think this is motive i can't conect 3g.can i do somthing about that??
There is no probelem with gsm but when i choose 3g, there is no connection .Setting it to 'WCDMA only' results in the same 'no parking' icon and no data. i changed my sim card, i choose my network provider manually, upgreade the phone with latest android version (6.0.1- Marsmallow),apn setting ok, but result is same gsm/edge. i also tried simcard with another phone and 3g is worked.
what can i do? i need help to fix this problem.

Hi all,
First time playing with dual SIM ad think Im missing something easy here.
I use GiffGaff (£5/m) and barely ever use data. Saw an offer from Voxi (Vodafone) for a 6GB data SIM. Grabbed one thinking I could use it as a second SIM just for data so I have a constant connection and a SIM I can move between devices where needed (MiFI, tablet etc, why I went with a second SIM rather than a different plan on my primary GiffGaff SIM)
Put the Voxi SIM in my Redmi, setup the APN and was greeted by the 4G symbol with the cross in the lower corner (no network connection but calls and texts work)
Now this is where Im getting confused. From what I can gather, only one SIM can be 4G while the other SIM will drop to 2G.
How do I go about setting this up correctly?
I do not need 4G speeds on the Voxi SIM as I only really need a constant connection, just enough to ping a few emails and Whataspp/Telegrams around.
Both GiffGaff and Voxi/Voda support 2G and would prefer the 4G to stay with GiffGaff for call quality.
So, I have:
GG in slot 1 (4G)
Voxi in slot 2.
APN set for Voxi.
Voxi set for Mobile Data
How do I now tell the Voxi SIM to connect over 2G and not 4G?
If I switch mobile data to the GiffGaff SIM, the 4G symbol from the Voxi symbol disappears so it must have switched to 2G but then GG is on data (with 4G sysmbol). When I switch back to Voxi GiffGaff goes to the no 4G but Voxi has the 4G with cross.
Is anyone here using dual SIMS like this in the UK?
Settings -> Network & Internet -> Mobile network -> Advanced -> Preferred network type
Did you try that?
Just tried every setting, in-between each one I toggled the mobile data switch and tried a ping and a Chrome page refresh

Some things to note, I dont know if these are bugs in the ROM/AOSP or normal:
SIM Cards:
SIM Slot 1 shows "giffgaff - myphonenumber" and when clicked shows 'Operator - giffgaff' & 'Number - myphonenumber'
SIM Slot 2 shows "Voxi" - blank" (I edited the name to say Voxi manually) and when clicked shows 'Operator - unknown' & 'Number - unknown'
Mobile Network:
Enhanced 4G LTE Mode - This toggles the settings for both the GiffGaff and Voxi SIM regardless of within which SIM I set it
(Just found a reference to it here but no reply so dont know if this normal?)
This applies to the actual network in these settings as well. GiffGaff shows: Network - O2-UK, flicking across to the Voxi side it also shows O2-UK even if I untick 'Automatically select network' and search manually, choose Vodafone UK (Successfully registers on network) but doesn't change to 'vodafone uk'. The main sub heading under 'Settings - Mobile Network' shows O2-UK as well the status bar carrier info has always shown both giffgaff and vodafone uk no matter what.
These change if I completely disable SIM1 though, then it shows vodafone. I presume this is all because SIM1 is 'Priority' though. Doesnt help when troubleshooting
Also I realized I forgot to mention the ROM is ResRemix, not stock (oversight on my part, haven't used a stock ROM on a device for years, forgot they exist )
I have also tried the SIM in my old Nexus 4 and it worked with no issue so I am assuming it is definitely a device issue rather then a SIM/Carrier one.
Im going to try another ROM over the weekend, probably Lineage, If I get chance to try and get a baseline to see if this is ROM related though (although the ROM thread, people are saying dual SIM is working, mainly the JiO network(?))
Its also harder to troubleshoot when Ive never used Dual SIM before and have no idea how thongs should look and feel etc

current ROM: RR-O-v6.1.0
Hello community,
I have a network connection problem:
No matter with which ROM - except the official Samsung 8.1 - I can not select an LTE mode on SIM slot 1. Although LTE is always preferred in the connection properties, it always stays in H + or EDGE. Even about the * *#*#4636#*#* function and and there "LTE Only" or "LTE / UMTS auto (PRL)" does not work. The mode in SIM1 remains in HSDPA or EDGE. It only switches to the respective mode if I set GSM only or WCDMA only. Then he also changes the net type. LTE does not work here. Although LTE is present - because with the original Sasmung8.1 floor works the conversion - the only error: after a restart is always WCDMA preferred in it.
I can use different Custom ROm (everything formally properly formatted before) - no ROM works.
The 2nd problem: on SIM2 slot no incoming calls go. Call can be accepted, but no sound is heard - but I call with SIM2 everything is as usual without error.
What do you have for tips?
Hi all after wifi not working anymore I bought a refurbished motherboard for my 9505 LTE version. After replacing it wifi is working great but I can't seem to be able to connect to 3G. In info menu (*#*#4636#*#*) I read -voice network: GSM and -data network: EDGE, no matter what I set in preferred network type. I contacted phone company (3 Italy) and they say mi sim card is correctly registered on the network and I should get at least H+.
Tried all the latest modem/bootloader avaiable, now I am on I9505XXUHQC1 (GSM/NON-HLOS COMBINED).
Also tried manual network selection and I can only have signal if I set 2G as preferred network type in Settings-WiFi and Mobile-Mobile network.
Any ideas?
Thanks
