Hi. I have bought iphone X new sealed in box in february this year. I bought it from a person i saw his ad in facebook. That was early this year so i dont really keep his number.

Then on early november this year suddenly showing no service.

I went to apple center. A week later they replaced me with a totally brand new iphone X.

After using this new iphone x for about 2months it shows no issue service again. I went to apple center again but this time they said my phone have been blocked by MCMC? Seriously? Why at the first place they replace me with new iphone and now telling me this new iphone is being blocked with MCMC?

Means this ne iphone have been blocked by telco? How do i find out which telco blocked it?

Finding the seller  is impossible i think coz i lost the conversation and his number. I dont feel suspicious since its brand new seaed and using the phone with no problem at all for 10months.

Or my iphone is totally unuseable now? Practically i have been using this phone for 11months but its only 1month++ old since Apple just replaced it 1month++ ago.

Is there any way to find out which telco blocked it? I went to celcom center they said they cannot check which telco is it from.
