What is the cheapest eSIM for Spain?

Jolli's Spain eSIM plans start from £1.99 for 1GB and scale up to 20GB for extended stays. You connect to Orange and Movistar — the two fastest networks in Spain. For short beach holidays or city breaks, the 3GB plan at £4.50 is the best value. This is significantly cheaper than O2 or EE's daily roaming fees in Spain.
