Network locked sim card inserted

My sister presented me this galaxy s6 phone from malaysia. I am from India when i inserted india sim card. I got the message network locked sim card inserted. I came to know from the internet all samsung phones are network locked, for that I have to make incomming or outgoing call for 5 mins. I inserted malaysia sim and (from india) made 3mins of call to malaysia and 2+ mins of call to my mobile in india. Inspite of this my mobile is not unlocked it is still locked. Please help me.
If i flash stock firmware from india will my s6 be automatically unlocked ??, without any side effects.
In internet I saw there are many sites which says they can provide unlock code but their charge is very high almost 50 USD. I have already spent almost 100RM for roaming calls. Please help in unlocking my phone.
Inserting the malaysia sim card will not work as the call has to be made through the network of the region the phone was bought. Using the malaysian sim in india is not enough as the call is still going through the indian phone network.
I already made a 3 mins call to Malaysia . Will it unlock if I ask to someone from Malaysia to make another 2 mins of call to me.
Only way to unlock a network locked S6 is to get the unlock code from your network or buy it online from reputable unlockers. Flashing ROMs will no remove the lock.
Suggest some reputable unlockers

The problem you may have here is unlocking services unlock the phone from a specific carrier. The region lock is not the same as the carrier lock that these companies provide a service for. A quick look on google brings up no results for region unlocking. At the minute your only course of action is take the phone to a samsung repair centre and hope they will remove the region lock for you.
I took my phone to local mobile service center and he unlocked my phone (dont know how he did) and my phone is now rooted. Now my question is, is the unclock permanent and can i flash stock firmware safely without getting locked again.
Please confirm

Sim Unlock is needed once in a lifetime and it`s irreversible. Anyway I don't understand why was needed to root your phone for sim unlock. Normally you can reset, flash anything now and your phone will be sim unlocked.
What do you mean by reset ? we cannot remove the lock by flashing a new ROM.
why dose it come up restart phone when i swich sim cards on my unlocked galaxy s6 eage and dose this lose all othe data and save picuters and contects
Please i do also have S6 brought from USA to Ghana and when i tried put on a sim, it said Network locked sim. please what should i do?

Region Lock and Flashing

Does Flashing with a Stock Rom leave the phone locked to the region it was purchased in or replace the region lock to the country of the firmware that was flashed. If that makes sense. Thanks for your help.
So in other words does changing the CSC alter the region lock status say you unlock the region lock with one CSC then change firmware with another do you then have to region unlock for that region

Carrier Locked

I'm just curious so I asked this. My M2 is Carrier Locked and came from the UK. I live in Asia so I can't use any network with it.
I'm planning to install custom recovery and ROM on my phone. Now, will that affect the phone? I mean am I still Carrier locked if I did install Rom and Recovery? Or I cant do that because I am locked? I'm really confused.
Hope you will answer this one. Kinda noob question. Lol Thank you.
If it's carrier locked to a network then more than likely the Bootloader will not be unlockable. Have you checked as it's usually only sim free network unlocked devices that have unlockable Bootloaders. If this is the case non stock custom roms are out. Also if it's locked to a specific network you'll need a pac code from the network it was on in the UK before it'll work on any other network.
Yes, you can install a custom ROM and recovery, but your phone will still remain carrier locked.
