It is a long shot but go to settings/general management/reset/reset network settings, then reboot the phone.

I rely heavily on internet, and lose my not so many marbles left when without it, I feel your pain.

From what I am seeing trying to look into your problem, you have done all that is suggested, other than a service centre visit

Hopefully someone who has suffered but resolved this will comment and share the steps for you :fingers-crossed:

Have you check your APN settings?

Replaced your SIM card? (It might work on other phones but not on yours either to not sitting properly or something else. So try replacing it.)

Take your sim card out and try this.
Do a factory reset and flash firmware with CSC file (not home-CSC file, backup first. )

Let phone boot without sim card first.

You're not going to get CDMA to work on the F version of the phone as far as I know you can only use GSM that's why nothing that's being suggested is working. You need to get a GSM carrier sim card.

Edit: Samsung Galaxy Note 8 SM-N950F/DS Dual-SIM 64GB (GSM Only, No*CDMA) Factory Unlocked 4G/LTE Smartphone International Version. ... This phone*WILL*NOT*WORK*with any*CDMA*Networks such as VERIZON, SPRINT, US CELLULAR.

yes i know m from india before the ota update everything was working fine please help

Ok i am trying to understand something.

Your device is SM-N950F/DS.

You are in india.

The phone can't connect to 4g/Lte after the security update. 2G and wifi is ok.

Before the update 4g/lte is fine.

You tried your simcard on other phones is able to connect to 4g/lte.

Is this correct?

May i ask how did you update to the latest firmware? ota, odin or smart switch?
