Have you changed operator? Do you have right settings on mobile network access point names?

thx for your rep, my net mode is set as lte/wcdma/gsm... however, when i set it to wcdma only, on low signal areas the signal drops dramatically, because of freq. change, i keep flashing new modems in order to find the suitable one :/

Hi

that is an option is most likely a modem issue, you could also see what modem your country operator uses ( check in sammobile) and flas it to see if you get an impovement

I already had the newest rom/modem installed since it came out, now I am rolling back all of the modems available in order to find the proper one...

I'm totally messed up with Service mode on samsung galaxy duos. Which caused not recognising any SIM. Help me out to reset everything to Service mode default. Thanks in Adv

@Iway76: You get a kudos for searching before posting, even though this isn't the right forum for you. I would recommend attempting to install a stock ROM using Odin, not Kies, and see if that helps. If that doesn't help, you may have to take the device in for service as you may have a hardware issue like mine, where the SIM card tray died while attempting to unlock the S4 - again - and it just was a coincidence that the hardware failed while working on the service menu unlock.
