Yes—you can use a Mint physical nano-SIM in your Indian OnePlus 12R if the phone is unlocked and its passes Mint's compatibility checker; the eSIM list does not decide physical-SIM eligibility.
“I'm a new graduate student from India with an Indian OnePlus 12R. It isn't listed as eSIM compatible on Mint Mobile's website. Can I use a Mint Mobile physical SIM with my device, even if data speeds are slower due to missing bands?”
摘要
Your Indian 12R has the required physical nano-SIM slot and overlaps several T-Mobile bands, including LTE 4/5/12/66 and 5G n2/n41. Missing n71 and LTE 71 can leave gaps in , but it does not mean your data will always be slow because the phone still supports T-Mobile's n41 Ultra Capacity band.
Your route forks on Mint's device-specific compatibility result, not on the absence of your phone from its eSIM list.
If Mint's checker says compatible and the phone is unlocked, choose a physical SIM. This fits both issuers' rules: OnePlus India lists a dual nano-SIM slot and no eSIM, while Mint expressly allows a physical SIM when eSIM is unsupported (Mint BYOP Help; OnePlus India 12R Specs).
If Mint's checker rejects the device or the phone is carrier-locked, a physical SIM is not a workaround: Mint's BYOP rule requires the phone to be both unlocked and compatible (Mint BYOP Help).
A physical SIM solves the eSIM form-factor problem, but it does not add radio bands that the Indian 12R lacks.
