Thank you for your reply
In places where 4G signal is weak, that method seems to be useful.
but in my place 4G signal is strong.
And in the case of ROM flashed by FAST BOOT, the problem does not occur.

What twrp r u using?

Did you remove all SIM and lockscreen codes before you installed those 'custom' / non-stock ROMs ?

already solved.
thank you.

The cause was the lack of APN type setting.
It solved by inputting "default, supl, dun" to APN type..
Thank you so much Powell:laugh:

Hi Bro this is very common problem... due to the fact you are flashing your cellphone with rom that maybe is from europe, you will need to get the modem from your country and flash the modem trough "ODIN" ,it works for me so eveytime i Use a rom from any developer from any country i just flash the modem with odin and wuala start working the 3g and hdsp+ connection do a little bit of search i will try to upload the files if you need help with that.... Do a little bit of search and this only flash the modem so it will not change any settings on your phone...

Its possible you are on the wrong Network, some network providers belong to the same group as such your phone may be getting signals from their sister network and not from the network your sim originates from
check menu> settings> wireless and network > mobile networks > and select the correct network , if its on another

Before doing something, make a nandroid backup & then flash this baseband.
I think that's not the problem
I think that's not the problem, should improve the signal reception, I've tried and I can only call at certain points in the city, out of town does not detect the network.
I tried XXAMg4, XXAMJ1

Yes, you're right. This is a known bug in maclaw's & oliver's roms, but maybe it works for him, nothing to lose, just need to try it.
I tried the XXAMG4 baseband but doesn't work...
I don't know where to download the XXAMJ1. Someone have the link?
kernel and baseband
No network/data bug still exists also for me, I use an S3 mini H3g with a WIND ITALIA SIM.
I've just tried to change my baseband with AMG4 nothing change, also now I've random reboot when I'm on GMS/WCDMA or GMS network :/

Yes, simply flash it & then reboot twice, because first time, phone will be very laggy
Read my FAQ (click on my signature) to see the latest baseband.

I asked this because I'm one of those who can't have signal working on Maclaw's works. (ITA H3G brand)
How do I backup things overwritten by this zip first?
