Airalo holds the lowest-price position for this destination (Nomad averages $0.74/GB globally, the lowest of the five providers we track). Prices are fixed year-round with no seasonal markup. For the best per-GB rate, the 20GB plan at $37.02 ($1.85/GB) saves $1.64 per GB versus the entry plan.
When does unlimited data beat a fixed plan for Mexico?
The unlimited data option in Mexico runs $3.37/day. The best fixed plan runs $1.85/GB (20GB plan at $37.02), which covers about 14 days at 1.5GB/day.

What is the cheapest network to use a travel eSIM on in Mexico?

Are budget eSIMs less reliable than premium ones in Mexico?
