Or Ultra Mobile, which, in addition to pretty fair plans, has cheaper and more useful ad hoc international roaming costs, if that’s something you might want. (Mint ruined their roaming rates a while back).
You’d still probably need to swap in a modem for a different region to use the L5 abroad, though.
If you’d like to take advantage of “cheap” eSIMs with the L5, you can buy one of the commercially available “eSIM adapters” that enable you to load purchased eSIMs onto them. (An eSIM adapter is a writable physical SIM card.)
