Hi guys ,i hope u can help me with this..
recently i just got the grand 2 like 2 months ago...when i tried to activate mobile data (of sim1) i had a problem ,it's not working,
I tried to trouble shoot the problem by changed apn's and stuff like that with the cust service,,nothing,
however,when i remove the 2nd sim the data of the sim1 ( which i want to activate) starts working ,I always make sure that sim1 os on wcdma and sim 2 mode is on gsm...i had sim 2 as clipped micro sim,however went to store and got a brand new micro sim to see if the clipped one was the problem ,nothing changed ,also swapped their position and placed sim1 in place of sim 2 and voice versa ,nothing happened same problem ,,,I also sometimes get a message saying:
the mobile network will be unavailable until you restart with a valid sim card inserted ,,and only the restart button available and u can't override it by pressing home key or anything so restarting in this case would be mandatory ,,that's why i chaned the 2nd sim card but nothing happened.
now i still can't get mobile data on my neww phone from sim1 and it's driving me crazy ,i think it's a software issue but am not sure cuz when i go to sim card manager and change the data service network to sim2 then put it back on sim1 ,some times the H+ appears and it works ,but not always and not for a long time,,,,,so the problem is between mobile data and dual sim functionality ,do u have this as a common issue ???,,please help
again ts steps i made:
1-re positioned sims in place of each other.
2-changed sim2 into an original micro sim instead of the clipped one i used to have.
3-i reset phone to factory defaults but same problem appeared

I think it is a hardware issue. take it to the service center and insist on getting the issue sorted out as they will try to fob you off with some excuse or other.

Hi.
I was searching for a solution for exactly the same problem.
I have the same phone as you and I get this to work if I select the option to allow Roaming, even though I fix the network operator to my provider's network. Strange but it should work.
Leifur.
m too facing the same prob in my grand prime 4g... i bought dis sum 10-15 days ago... plz help me to solve dis... othrwise i hv to use it as a single sim... any suggstion...plz help
Sent from my SM-G531F using XDA Free mobile app
Here is the best solution: I faced the same problem and fixed it doing the following...
First restart your phone, when you do that you will see the sim configuration settings screen appears at the boot time and allows you to choose which sim card to use for the Data Service Network... it has three options
1. Sim1
2. Sim2
3. Data service is Off
the third option is active and set by default which is why my cellphone was not working internet and i changed it to Sim1, and it worked perfectly so you have to try it again and again by changing the sim card in their slot... hope that helps!
my 4g on this phone is stopped working and there is so much hang problem in this phone, don't buy it, I did factory reset so many times in this phone to remove my problems but they remained as it is. I am writing about samsung galaxy grand prime 4G phone, model G531.

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.

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.

In fairness post might be useful to some .
Where it is actually the sim holder .
But 99% of the problems are not the sim holder .

i am facing the problem with my LGF180

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.
Hello,
I have this cheap Homtom HT20 Android phone that started manifesting the 3G internet issue soon after I have bought it. I can do messages and calls ok on 3G, just not internet. It works for web browsing and few other things but as soon as it does a few MiB's of traffic at once it starts going unresponsive. All fine on 4G or Wifi. Tried swapping the SIM card slot (it is dual SIM, seems to start working when I put the SIM card into SIM slot #2, but only for a few hours). Tried upgrading ROM, still the same. Is there anything I could do before I get to the GSM service ? I do not care about any warranty, I am not sending this thing back and froth to and from China.
Thanks!
I have same phone, same problem...

There could be 3 possible ways.
1) Software bug
2) sim slot pin breakage
3) sim card chip problem
Identify the root cause at first.

2nd and 3rd not possible. Since data and messages are working.
Can you provide more information.
Are you on 4g network.
What type of error do you get.
Your circle.
Have you changed your network settings using *#*#4636#*#*?
Have you tried calling using 3g and 2g only?
If not choose WCDMA only (use above code). Also try with GSM only.

Same problem here. Solution for now is to change to 2G network, at least for me. When I try to call with 4G preferred sometimes it work, but when it works they can't hear me and I have to scream. This Pie update have so many bugs it is ridiculous. I can't believe they put such ****ty update to the masses it seems like BETA version. In Oreo when making call phone switches from 4G to 3G instantly now in Pie switches worry slow if it even switch and the signal is so bad that the call drops and that is in places where the signal is perfect
Hi, since last 4 days i am facing same ptoblem cellular SIM in slot 1 not working for incoming and outgoing calls and outgoing sms but internet and sms service (invoming) is working perfect on 4G
When i switch it to 3G/2G it shows no signals
But when i inserted this same sim in slot 2 all things work perfect. same problem occurred even when i inserted other network sim in slot 1 (internet and sms(incoming) worked but unable to do calls) I had factory reset but problem not solved
I am using poco x3 nfc
I anyone have solution plz tell me
