  In this letter, we introduce a general cellular network model where i) users
and BSs are distributed as two general point processes that may be coupled, ii)
pathloss is assumed to follow a multi-slope power-law pathloss model, and iii)
fading (power) is assumed to be independent across all wireless links. For this
setup, we first obtain a set of contours representing the same meta
distribution of SIR, which is the distribution of the conditional coverage
probability given the point process, for different values of the parameters of
the pathloss function and BS and user point processes. This general result is
then specialized to 3GPP-inspired user and BS configurations obtained by
combining Poisson point process (PPP) and Poisson cluster process (PCP).
