Using Apple Card.
Can I use my own sim card (Lycamobile)
if I purchase a phone with my Apple Card with monthly payment?
I also go over seas (India) will I still be able to use my another SIM card on my phone and/or my phone will be locked?
1) If your iPhone is locked to a carrier then SIM cards from different carriers will NOT work.
2) You may purchase an iPhone with your Apple Card on a monthly payment program provided that you have enough available credit equal to or more than the total cost of the iPhone.
3) See answer to point 1 above.
