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?
Hello everyone!
I've got my Sprint s4, unlocked it to use in Canada and flahed JFLTE-GPE. Since then i had no problems for half a year, but this autumnthe ROM got an update. It has lost all the personalisation and other stuff and moreover started rebooting randomly. I decided to switch to OCT-L, and the phone couldn't connect to the network. I tryed different settings and it either was written "Sprint" or "International" (at the network status). But also there was a setting at which it was rapidly changing from "Sprint" to my SIM card network. I flashed JFLTE-GPE back, but nothing changed except it didn't connect to my SIM card at all. I flashed OH1 modem (saw it somewhere on the forum) but it didnt give anything.
Help me anyone please!:crying:
I flashed phronesis n7 port rom to my n9002 note 3. The problem is, have no mobile network. The phone says no sim card inserted when I have both slots with working sims from 2 different network. I tried the n5 port rom and similarly it didn't find the sim cards either.
Additionally both roms doesn't seem to recognize the second sim card slot, as there was only one no network icon in the statusbar.
My question is, is there something I'm missing, or some kind of fix to solve the problem let me know please. I really want to use any one of the two roms.
Ps. The n5 port wasn't going pass the WiFi network screen...blanked out when I pressed next then the same screen reappeared
HELP!!
On that roms thread you will see a big faq list and guide as to how to get help .
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.
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
