  In comparison to the original Tolman VII model, Exact Modified Tolman VII
(EMTVII) with one additional parameter can increase the compactness of compact
object. When the compactness is in the ultracompact regime, the quasinormal
modes~(QNMs) of the trapped mode as well as the gravitational echoes become
more viable. Starting with the EMTVII model, we introduce nonlocality into the
matter sector and analyze the effective potential, the QNMs, and the
gravitational echoes of the compact and ultracompact object in the nonlocal
model. The nonlocal gravity version of EMTVII~(NEMTVII) is parametrized by the
nonlocal parameter~($ \beta $), modified Tolman VII parameter ($ \alpha $), and
the compactness ($ \mathcal{C}$). It is found that the nonlocal profile
produces the smeared surface and consequently reduce the compactness. The
maximum compactness $\mathcal{C}_{max}=0.4$ occurs when $\alpha=0=\beta$, i.e.,
EMTVII with no smearing. For relatively small value of $\beta = 0.01$ and the
compactness $ \mathcal{C} \lesssim 0.2667$~(with $M=2.14$ solar masses,
$R=11.835$ km at $\alpha=1.4$), the causality condition and the dominant energy
condition~(DEC) are satisfied. The quasinormal modes of the gravitational
perturbation are calculated using Bohr-Sommerfeld (BS) fitting and we find that
the nonlocality produces less trapped modes than the original (EMTVII)
counterpart. At high compactness, gravitational echoes are simulated
numerically. Echoes are found to exist in the parameter space where the
dominant energy condition and the causality condition are violated.
