Apple Event: May 7th at 7 am PT
I bought the iPhone Xs max international version and used more than 1 year (warranty expired), the software update is completely normal. Currently, my iPhone has a Sim not valid error and it can no longer be used. What do I do now to fix it?
Serial number: FF*****PHC

iPhone XS Max, iOS 13
The phone you have is locked to a carrier, and only a SIM from that carrier will work in it. You need to contact the carrier and ask them to unlock the phone. See—>How to unlock your iPhone for use with a different carrier - Apple Support
Note that there is no such thing as an “international version”. iPhones are localized to the region where they are intended to be sold. This is different from “unlocked”.

I can't know which carrier my iPhone is locked on. Because I'm living in Vietnam. Serial: FF****PHC. Model ... LL / A.
Can you help me contact the carrier that has locked it?

There is no such thing as an "international" version of the iPhone.
The phone you have is carrier locked. Only the carrier it's locked to can remove the lock. Contact them.
Try the 4 major US carriers, Sprint, T-mobile, AT&T, Verizon. It’s a US market phone from the model number.
I checked, it's Sprint carrier and it's got Blacklist. Now, what am I going to do to unlock it?
Nothing. It's a stolen phone. It's blacklisted, and Sprint will absolutely NOT unlock it for you or anyone else.
Recycle it and go buy a phone you can use.
Thanks for the help. I bought a new Iphone Pro max.
