Problem with mobile network "NEDJMA" on the Galaxy S i9000 / i9100
Hello everybody
In first, please excuse my bad English.
We have a big problem in Algeria with the mobile network NEDJMA on the Galaxy S i9000/i9100, the sim isn't recognized, in best case, it's recognized, the network bars are here, but it's impossible to make or receive a call, it's unreachable. That problem doesn't exist with the others mobile networks (Djezzy and Mobilis).
For the i9000, I've try to flash many roms and custom roms, with so many modems, but in vain. the phone refuse to recognize the sim. i have also try to put that same sim in another i9000 with the same custom rom CM9 4.0.4 and the same modem JVT, and guess what, the phone recognize the sim and mobile network works great!
For the i9100p, I've flashed a JVS modem and I've reduced the frequency of network bugs from many in one day to 1 or 2 in 4 or 5 days.
So, what you think about this problem? if is not the modem who we should change? then what we should do?
thanks in advance

hi everyone ,
1- im not in USA , but my phone model name is SGH-T999 , (when i bought my phone i didn't know that it is a T-mobile version !)
2- my issue is that my phone not connecting to 3G , even that there is an option for 3G in the settings but when i choose it the network become unavailable .
3- i tried wipe data and wipe cache , still cannot connect to 3G , only EDGE ! ( E sign )
4- I tried to install like 4 official ROM using Odin , but any of them didn't work , always received a FAILED message on Odin and "unsupported dev_type" on my phone
5- then my phone didn't turn on , ( i didnt know what to do cz i cant fix it using Odin !
6- Suddenly I noticed that my model Name is NOT GT-I9300 , but It is SGH-T999 ( i figured that in the CWM recovery menu )
7- Here i noticed that I DON"T have the "world model" of Galaxy S3 ,but it is the T-mobile version , so here i immediately installed the T-mobile stock ROM , and it worked using Odin and my phone got back to life
8- Now i just want ur help plz to make my phone connect to 3G Network
can I install the "world model" ROM for ex the UK ROM or middle east ROM ?
if yes, will it fix my problem ? if not how to fix my problem
thank a lot
T999 is a completely different device from the I930x line, based on a dual-core Qualcomm SoC (instead of the quad-core Exynos found in the international models). Go to the US/Canadian Galaxy S3 forum for support.
IIRC the T999 is lacking support for some or all European 3G bands, which is why you are not seeing a 3G signal with it.

Hey Guys , I recently purchased an S6 edge G925F from my local market , in used condition , it came with Android 5.1 Lolipop but when i upgraded it to marshmallow , its GSM capability stopped , which means that it detected my local network but failed to register on my sim network , it would say " could not connect , try later" , G925F roms work completely except sim communication , and when i had this issue , i took it to my seller to repair it , and he refreshed it to lollipop again and said that dont upgrade to marshmallow , because it has GSM bugs etc , and i asked him about what happened and asked that whether it was locked or etc , he answered that my phone got locked (i dont know if its carrier or bootloader or baseband lock) but he said it got locked due to baseband change , My questions are :
Q1. is this a reconditioned phone that was previously some carrier phone that they converted it to G925F ?
Q2. Do locks (network , carrier , baseband , etc) exist for G925F which would produce GSM issues ? like i had ? sim works but fails to register on gsm network
I will be glad if anyone could help me out! (P.S IMEI remained intact , didnt get corrupt, despite no network capability , and i checked , in my country it isnt flagged stolen or etc)

hello,
i had to flash my infinix note 4 x572 with a relatively older oreo firmware
everything works fine and i even rooted the device
but i can't register to my sim card's network (vodafone egypt)
here's a quick video screen recording

and at the end it says (can't connect to the network right now)
i think the firmware i flashed wasn't designed for egypt ?
