I am selling the popular mobile translator, Langogo. * It has a Wi-Fi router function. * It has a built-in eSIM, but since I'm using the Wi-Fi function, whether or not a SIM card can be used needs to be verified. * Used a few times, but there are no noticeable stains. * Purchased in February 2019. * Body only (no cable, no box) * Recommended for overseas travel and dealing with foreigners in stores, etc. Thank you.
