Vishal is a Navigraph member and not a scammer. He is the responsible person for the Simlink app. Normally, we don´t offer a 1:1 support but in some cases, we must do this and therefore the offer to you via a DM.
Again, this guy is a Navigraph member/employee and you can take his offer, or not but he and all other team-members trying to help here. For the next time, look on his profile first before you wrote such postings …
Thank you very much,
Richard (also a Navigraph team member and exactly in the same position as Vishal)
