MBK is probably the best choice...  lots of range, many stalls...  the fakes are fairly obvious, especially if you have researched what you are after. 

Do you have any idea about mobile phone shop name NASA in MBK ? 

I got a really good deal on a brand new Samsung J6 at MBK. I recommend doing research online regarding the phone's used or new value and if it's a good deal, buy it. I can't remember the name of the store. It was among the many stores on the floor with all the phone shops. I chose truemove as my service provider. It's under 1300 baht for a sim and a year of unlimited internet. Download LINE and use it for texting and calls and you won't need to 'top up' at 7/11 unless calling someone who doesn't use LINE. It's an incredible value. 

NASA is good.

Make sure you know what you want. 

Be careful whether you get a warranty or not.
