Dual SIM and mobile data doesn't work after upgrading to marshmallow - Galaxy Grand Prime Q&A, Help & Troubleshooting

hi, i have samsung galaxy grand prime SM-G531H. the original version of my phone was android lollipop but recently i upgraded it to marshmallow. but i have some problems, the mobile data doesn't work (the wifi connection works perfectly tho). i've tried everything the internet have said: factory reset, networks settings reset, turning on/off the airplane mode, turning on/off the cellular data, changing the APN, taking out the sim cards from the slot, rebooting the phone, but nothing works.
but recently i've found out if i only use 1 sim card slot the mobile data will work. but i need both of the sim cards. anyway i usually use the 1st SIM as mobile data, and the 2nd one for texting/calls. so... anyone know how to fix this problem? thanks in advance.

WiFi will not turn on due to no Sim Card

I've searched for 2 months trying to figure this out. Basically my sim card will not be read due to the hardware issue so it is the motherboard, now the problem is i cannot enable WiFi due to not having a sim card inside the phone...when i was on 4.4.4 it says Smart Network Switch and something about not being able to enable due to no sim.....well i tried a custom rom to see if it would remove that feature which it didnt so i went back to 4.4.2 and it doesnt have the smart network switch but it still doesnt allow WiFi to turn on....now the funny thing is before i had the Sim problem i had WiFi on and it stayed working after the sim stuff happened, I factory reset my phone when i was going to install a custom rom before evening knowing WiFi wouldnt work without a Sim so obviously to my surprise when i went to turn on WiFi it wouldnt work, seems like the S4 has a stupid feature imo that if you dont insert a Sim it wont allow WiFi to be turned on. Can anyone tell me if under root or something i can get rid of that feature or some how turn on WiFi in the files or root section of the phone?

I have a similar problem. I have an AT&T S4 I337 that was used with Net10 Network and had the intermittent sim disconnecting problem but it was working well when ik worked. After I changed the Net10 sim to an AT&T non subscribed sim the Wifi, GPS and Bluetooth stopped working. I thoug hit was some firmware problem so I decided to Odin flash the NB1 Rootable Firmware but the problem persist ( can turn wifi and bluetooth on, and GPS turns on but cant get a location). I also tried the complete stock version of NB1 and also did not work. I constantly get a security Notice saying "Unauthorized actions have been detected. Restart your phone to undo any unauthorized changes". I restart but the problem persist. It seems to reboot into a Recovery booting and then restarts. The thin is that the Knox counter is still 0x0.
Did you resolve your problem? If not could some one help us PLEASE!!!!!!:crying:
Any one with that could help me identify the problem?

Nokia 6(TA-1000) cellular network not work after Android Oreo

I just upgrade my Nokia 6(TA-1000) to official Android 8.0.0 (Oreo).
Then my Cellular network won't work anymore.
I live in Hong Kong, using sim card service "CMHK".
I think it is LTE/WCDMA mode.
Tried "*#*#4636#*#*" and changing the settings.
But the connection always shown IPv4: Failed(2)
The phone notification show it is connected and running 3G network.
But the upload/download speed is always 0KB/s.
Reset to factory setting already.
Before upgrade Android everything work fine.
Anyone have the same problems?
Now, what can i do....?
It seems I can't even downgrade my Android.
Only, have to wait for next update and hope it will fixed?
I think i am screwed.

I already do factory reset on System Settings.

It still Android 8.0.0 and problem still exists.

No, there is a lot difference between system reset(soft reset) and recovery reset (hard reset)
Try it, may be it solve your problem

Have you tried other SIM cards, whether you work in your cell phone! Tried to register your network operator service in the settings! Set preferred network ~

I use official update.
All firmware should be correct?
BTW, I get a new sim card from ISP but cellular network still not working.
Also, tried both sim card slot 1 and slot 2 nothing work.
May be new system not compatible with my SIM card service only which is "CMHK" aka "中國移動香港".
Hope next update will fix that...

is there anyway to get rid of it.i asked for nokia chat support but they are asking me to take mobile to nearest service center.

I just turn off the cellular network yesterday.
After I wake up from bed, my phone Google service can not connect from wifi(can't use email, Google store).
BUT! After reinsert my sim card and turn back on cellular network, everything working now.
Both 4G cellular and Google service all good.
May be some part of the network is cached.
So, if you encounter this problem just turn off cellular network and wait.

It seems that, the old slot 1 cached your sim card.
So, you change to slot 2 work, but you can't use SD card.
And I found that if you wait a long time the cache will clear.
You can try to insert sim card back to slot 1 after 1-2 days.

The only option was left to flash stock firmware, but as it updated to oreo, its bootloader has also been updated so I will suggest you to wait for official oreo firmware to release, please don't try to downgrade your device for now, it can brick your device very badly, keep patience, if any solution will come out, we will definitely tell you
Sim detecting issues of Nokia 6
Have you got it fixed now?

Yes, I got it fixed...
1) Just turn off your cellular network.
2) Wait for 1-2 days.
3) Turn on your cellular network again, it should work.
How can I off cellular network. Will keeping it in flight mode helps?

Thank you for raising this question. My phone got the same problem. I am just wondering if I should send it to maintenance center but I guess they will just do reset.
And by saying "turn off cellular network and wait for 1-2 days", do you mean by just turning off the data usage, or turning it to flight mode/ turning the phone.

radio/network/modem/dual sim problem. pls help

my moto e3 power has a serious network problem
in single sim mode it works fine, but in dual sim mode the non-data sim constantly loses signal (emergency only/no service)
and when I play around with switching things on and off like airplane mode/mobile data/sim card slot activation it gets worse, both sim cards loses signal and sometime even showing that the sim was enabled even when i disabled it
there's so many things I've tried and I honestly don't know what I've missed
here's some things I've tried
clear cache from internal storage, from twrp
reset app preferences
safe mode
network settings reset
factory reset
flashing fresh stock rom (download only and format +download)
custom rom ( lineageos 14.1 7.1.2)
downgrade stock rom to s131 (currently s147)
maybe there's something else i tried but i don't remember
any suggestions?
oh and I attached some screenshot of my phone's anomaly
pls help:fingers-crossed:

Idea sim not working in Mi A1 after Pie January 2019 patch update

Hi there, I updated my Mi A1 through OTA to pie january update via Idea mobile data. But after it rebooted the network signal was gone. I tried inserting Airtel Sim card, it works.
It somehow has problems with Idea sim. The same idea sim works absolutely fine in other phones. Tried factory reset but to no avail.
Here is the list of things I already tried,
1) Inserting other operator's sim. Airtel SIM worked.
2) factory reset
3)Changing from 4G network to 3G or 2G. No use.
ANY HELP WILL BE APPRECIATED.

Same issue here, but on Cricket. I cannot make calls at all. I put this SIM in another phone and it works fine. I put the other working SIM in this phone and it doesn't work. Tried setting preference to 3G and 2G since I saw threads about VoLTE being broken by the update, but still nada. This really sucks. Can anybody help?

No SIM card error

Hi All,
Recently my one note 5 (N920I) experienced no SIM card error and i couldn't make any call or on data for my phone. I've tried below method but still couldn't solve the problem. Hopefully someone can help me or advise what i need to do. I haven't root my phone yet though. would factory reset solve my problem?
1. tried re-inserting the SIM card and retart the phone
2. tried to delete the cache data on the phone
3. tested SIM card is working on other phone
4. tried to check though the software/firmware details and found that baseband showing unknown
5. found IMEI is missing from my phone when entered *#060# but i'm able to retrieve my IMEI# through other means
i have that issue too, for some weird reason 2g seems to work. calls can be made and answered but mobile data only works on 3g or 4g or 5g.
if you set your phone on 2g only, it should recognize the sim card
