BNESIM does not provide a true unlimited high‑speed data plan for Mexico. The only plan with “Unlimited” in its name, Mexico Unlimited 10 days, gives 3GB per day at full speed and then switches to 1Mbps for the remainder of the 10‑day period, so it is not unlimited in the sense of unlimited high‑speed data.
Travelers can instead choose fixed data plans that include large data allowances. For example, the Surf 100 GB in Mexico for 30 days offers 100GB of full‑speed data for a 30‑day validity, and the Surf 100 GB in North America for 30 days or the 100 GB no‑expiry options deliver the same 100GB of high‑speed data for their respective validity periods. These fixed plans may be more cost‑effective than the daily‑limited “unlimited” option.
