How do I turn on data roaming on my iPhone?

A. 1

First, you have to sign up for unlimited data roaming products.
Otherwise, data usage fees are prohibitively high.
The way to set it up is
Settings - > Cellular
after going into
Turn off LTE
Turn on data roaming.

It's good to sign up for the data roaming plan
It will cost about 10,000 won a day.
If you think you're using a lot of data, you can use a local USIM.
If you use a local USIM, the fare is extremely low.
If it's an overseas trip, you won't have time to do this and that on your phone like in Korea
It's much more economical to buy a local USIM and put it in.
