SIM call gets disconnected within 2-5 seconds of inward/outward call

[S22 India]

I have S22 ultra phone(256GB variant) bought from South Korea. It has Qualcomm chipset. Issue is during an inward call, as soon as call is accepted, call gets disconnected. The person need to call 2nd time again for call. Same pattern with outward call, call gets disconnected when other person accepts my call, then again we need to reconnect. This happens all the time and it is irritating.

Please give a solution for this problem.

Hi @S22 India 

The issue couod be with the person calling you or is this happening with all callers ?

With your user name including " India " and that you say you bought the phone from South Korea have you imported the phone to your region ?

If so it could be that the bands and frequencies in the phone are experiencing issues with the bands and frequencies your chosen home network uses.

Also please do check your masts where you are to see if they are experiencing issues.

As a process of elimination can you try your sim card in another phone and then another sim card in your phone and then see what happens. 

You can reset the connection settings in Settings > General Management > Reset > Reset Network Settings.

Just to add with imported phone's you may find that the Samsung Support Department in your region may not be able to provide support for an imported model.

I wish you all the best.

Dear BandofBrothers, thanks for your comment

I reside in India and bought S22 ultra from South Korea. I did all the workarounds like

SIM card changed to another phone -> it works well in other phone (Made in India phone)

Settings > General Management > Reset > Reset Network Settings. -> Didn't help much

I wanted to know, is it a phone issue? I see lot of threads with similar issue and solutions like above and software update may help it seems. But none is working at the moment.

Don't know if Samsung is planning to roll out a fix in next software update.

Ok so imported @S22 India  👍

Have you checked what I've spoken about bands and frequencies in the phone to that of what your network uses ?

It's a conundrum as to why the calls fails 1st time and then connects the 2nd time !

The Korean version is limited in terms of the bands it supports in India, http://specsgate.com/frequency-checker/in?device=samsung_sm-s908n_galaxy_s22_ultra_5g_uw_td-lte_kr_2...


This is not a software issue, the Radio is just not capable of dealing with the requirements in India.
This is one of the drawbacks of purchasing non local devices.
