Redmi Note 3 MTK problem with SIM CARD

Hi All,

i seldom post here but i am in need of help.

i been using Redmi Note 3 MTK version, China domestic model for quite sometime.
it works great until my Vietnam trip last week.

when i was there, i purchase a local SIM which is by Mobikom.
at first the viet girl struggle to make my phone recognize the sim.
eventually she made it working.

long story short, now i am back to KL. now my phone CANNOT detect any sim card at all.
it keep saying NO SIM CARD. even the MIUI sim setting is disable.

i tried a number of ways to revive the phone but still no luck.

1. Tried Reset factory - No good.
2. Tried flashing Recovery firmware and clear cache - No good.
3. Tried downgrade MIUI 8 to MIUI 7 -0 no good.
4. Tried upgrade from MIUI 7 to MIUI 8 - No good.
5. tried flashing China MTK developer ROM - No good.
6. Tried Root all the above - No good.

Any help would be grateful , even i have to pay for your service to revive my phone back.
I do not want to spend RM 1k for another phone right now.
