But what if you're on the road and have an emergency? Wifi isn't going to help you there
Correct....that's why we have "Travel Pass" with Verizon (other carriers have similar) for use only in an emergency or if needed on road. It automatically kicks in if you try to make a call outside a wifi area . Otherwise it's wifi calling for everything ...free to the USA and minimal charges to SXM and other countries. Obviously a long call would just be made using the Travel Pass....
Probably not appropriate in this case if the OP doesn't have a useable network to start with but the wifi calling would work ...and that "old S7" is my main phone right now...works great
