If you don’t have a Proxmark, there may be somebody near you that can help you out.
Where are you based?
also possibly check out THIS Wiki, in the “meet and clone section”, it is pretty light on contacts at the moment, but you never know.
Ideally It would be great to build up this “database” or even have a Partners Map that includes reccomended unoffical piercers plus Cyborgs with Proxmarks etc. but until then…
