Does an international iPhone12 work with a US carrier?

Does an iPhone purchased in India with model no. A2403 work in the US with a US carrier?

The key question is carrier lock. If the phone is locked to a carrier in India it will not work with any other carrier in India or anywhere else in the world, unless the carrier it is locked to is willing to unlock it. If it is not carrier locked it will work almost anywhere in the world, but may not work on specific LTE or 5G channels. You can research this for yourself. Go to this site and find the phone model→https://www.apple.com/iphone/cellular/. Note the channels that phone supports. Compare that to this list→List of LTE networks - Wikipedia, the free encyclopedia and see the channel compatibility.

There is no international iPhone. A carrier unlocked phone will work in other countries.

I do not know why it would not be compatible with the US market. Hopefully someone else will see this thread and be able to offer some feedback.

You should buy an iphone in the country you want to use it.

5G in particular has different specifications in USA, like mm wave

You will also not get warranty or repair service in a different country
