I just picked a random country UK:
Silent Link: $1.15-$4.65 (varies depending on which network you happen to get connected to)
Sovran eSIMs: $0.73-$5.00 (varies depending on which package you pick at...
silent link always selects the cheapest network, so wouldn’t compare to expensive ones unless you know for sure that your sims support the expensive networks then this would be a benefit
