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.
hello frnd i hv problem with my g7102 is not connecting to internet i have tried everything like mobile hard reset apn setting flash new roms but still data connection wont turn on but wifi is working please help guys
The only solution is to fix the hardware
My samsung SMG- 7102 network problem.when i start the mobile data then network are automatically no service pls help me
I'm having problem with a Asus Zenphone 2 Laser ZE551KL.
I'm from Dominican Republic. I bought this phone to use 2 sims. one for calling (ORANGE) and the another for LTE Data (TRICOM).
This is my history:
When the phone arrive i put my 2 sims cards to the phone and update to the lastest Android version available: WW_ 1.17.40.1234. After that i can use the sim card ORANGE for calling but the data sim cards isn't detected by the Zenphone. I tried with another TRICOM Data sim card with the same result.
Also, i tried with a sim card from another company (CLARO) ant it works. it was detected by the Zenphone.
Later, i flashed CM 13.0 for the Zenphone and i get LTE data using the TRICOM sim card but for a 1 minute or less. I mean, when the phone boot up it get lte data and show me the icon LTE indicating that is working but after one minute the signal turn off. I only get data for that short time.
Also i test the lte sim card on another zenphone Z00A and it worked perfect.
the problem is that when using stock rom the sim card for lte data is not detectec. when i use CM 13.0 Rom, the sim card lte is detectec for a minute and it get loss.
Any suggestion about it?
I would like to try changing the modem version, but i don't know how to do it.
Did you check your APN settings? Different companies use different settings. Maybe the ROM doesn't have them set for one or the other SIM
I am using two sims in india SIM1-> airtel(2G mode) and SIM2->Jio ( LTE mode).
This message pops up frequently at the bottom of screen.
Any one aware of how to fix it ?
I am also facing the same problem in S7 Edge. If you are able to find a solution please share it.
jio sim seems to be the culprit kick it out of the phone and problem solved, was facing the same problem one of my two sim cards was a jio sim, did a little research and found that mostly those who were facing the issue were using jio as one of the sim cards.
The thing you need to do is go to Setting> mobile and networks > select network operators> choose the sim card which you use for data usage > select on ( Select automatically- automatically select preferred network)
I satisfied with this solution, look that you might be too.
Me too facing this issue in my j7. Using jio in slot 1. Anyone found solution ?
I called to jio customer care but they told me that your sim card is damaged. Visit nearest center to issue new sim card.
But i dont think this is the solution.
Most likely it's CSC problem , You may flashed a different CSC than yours
Check your APN settings and see if they are properly set.
hi! Has anybody found a solution to this issue? I bought a #Note9 yesterday and same issue exists. This happened on all my past devices too Samsung S7 and LGV20. I once changed the SIM card still no luck. Any update on this matter is greatly appreciated.
Hey there
I have the following situation and basically this is the reason why I've bought a dual SIM
SIM 1 - Vodafone Italy
SIM 2 - Yallo Switzerland
SIM 1 is used ONLY for receiving phone calls and I want to have it 24/7
SIM 2 is more a working SIM, I am using it for phone and internet
Evening I want to switch off SIM 2, don't want to be bothered with calls nor I care for internet.
First problem when I try to "disable" SIM 2 I got the message that the SIM is set as primary (whatever it means) so I cannot disable it (why ????????????)
Trying to findo out what is the reason I have discovered that if I select data on SIM 1, then I can switch off SIM 2 (whaaaaat ?????)
Seems that I am not free to do it
The other thing is ... to "disable" the SIM, I have to go to Settings | SIM and mobile network click on SIM 2 and disable
This is not what you want to do just before going to sleep, I expected something very easy to switch off SIM 1 or 2 based on needs
How can I solve the problem ?
Cheers
Steve

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
