In this paper, we study-stability and weak-stability of coarse isometries between Banach spaces for a free ultrafilteron. As a result, for a coarse isometry(), where() are two measure spaces, we prove that the following conditions are equivalent:(i)The mappingdefined byfor anyis a linear isometry ;(ii)For any,exists and;(iii)fis-weakly stable;(iv)There exists awithsuch that $$\begin{aligned}\Vert Tf(nx)-nx\Vert =o(n)_{{\mathcal {U}}}. \end{aligned}$$
