g925w8 no sim card problem

S6 edge when i insert sim the phone asks for a restart but after that i get no sim card message and if i reinsert it the same thing happens again.
Tried reflashing the phone thru smart switch but no luck.
Any ideas on this?
Thats what its supposed to do. Doesn't support "hot swapping" sim cards. Every time you take out your sim card and replace it with another or the same, a message will popup telling you to restart your phone.
Im assuming, of course, that you are not trying to use your phone without a sim card installed.
This phone has a problem and the problem is that when i put a sim card it asks to be restarted which is pretty normal but after the restart the phone shows no sim card but if i take out the sim it will prompt to be restarted again because the sim has been removed. So basically the phone somehow recognize the sim but does not read it.
Sorry if my post wasnt clear enough.

Is there only me facing new rom installation problem using jio sim ?

I don't know if it is the right place for this.Because this a weird problem with a weird solution.I am using jio sim in second slot ( I don't know why I had inserted in second slot and now I can't use the the sim in first slot... ).
Now here is the problem.Whenever I am flashing new ROM,on the 1st boot phone is freezing at boot animation(not mi logo) and restarting again and again.
Now the weird solution :laugh: .If both sim removed , then it is booting good.After first successful boot without both sims, I have to insert jio sim in the second slot and let it boot.After second successful boo, have to insert another sim oin first slot (without jio sim) and let it boot.After 3rd successful boot, have to insert both sim. Now it is good to go.
Lol.....Lol....Lol.....

Same problem here. Even Idea SIM doesnt work. And Vodafone too. Only thing that we can do now is to wait for someone to find the solution, visit the service centre or perform this in the order given:-
1. Remove both sims and boot.
2. Insert sim(Airtel/voda etc) in 2nd slot and boot.
3. Remove sim from 2nd slot(airtel/voda etc) & put jio in 1st slot and boot.
4. Then try booting with both the sims

Sim suddendly disappeared

Hello everyone !
I have some issues with my sim card on OpenBeta3 + custom kernel (Bluspark).
One day, without doing anything, sim card suddenly being not recognized on each slot, swapping slots or rebooting doesn't have any effects.
(My sim card is good, tested with an other phone)
Catlogs says about a "CARD_IO_ERROR" when sim disappear.
I've done full factory reset or resetting network settings and it didn't solve my issue.
Then i flashed full stock rom by fastboot way + reset network settings, it seems to solve the problem (waiting some days to see if this problem occurs again).
Is there any people who are experiencing some sim disapearring ? And how you managed to solve that issue ?
Thanks
