No, BNESIM does not provide a true unlimited‑data eSIM plan for Mexico. The plan titled “Mexico Unlimited 10 days” gives 3GB per day at high speed, after which data continues at a reduced speed of 1Mbps; this is a capped plan rather than an unlimited one.
If you need large data allowances, BNESIM offers fixed data plans such as the “Surf 100 GB in Mexico for 30 days, ” which includes 100GB of high‑speed data valid for 30 days, and similar 100 GB plans for other regions. These fixed data plans can be more cost‑effective for travelers who expect to use a substantial amount of data.
