What are the roaming cost implications for US or EU SIMs in Brazil compared to eSIMTrends?

Data from global roaming agreements consistently places Brazil in a high-cost roaming tier for most US and EU carriers. This means that utilizing a home SIM for data services can incur substantial daily fees, often far exceeding the cost-per-GB of dedicated travel eSIMs. eSIMTrends highlights this trend to emphasize the significant cost efficiencies of using local or regional eSIMs, which provide a more economical and predictable data solution compared to traditional international roaming charges.
