Helpmobi located at helpmobi.io, which claims they can locate a mobile phone, appears to be a scam. If you enter any bogus telephone number on their website and request the location, it will claim it has located the fake number and then ask for your credit card information to make a payment of £1.00 in order to get the coordinates. Seems to be a trick to get credit card information.

Helpmobi claims it is completely legal to request a mobile phone location, but this is not entirely true. Even though it's technically possible to track someone via a cell phone using GPS or tower triangulation, it's not always legal. Unless you are part of a law enforcement agency and have a warrant to do so, it is usually illegal to track the physical location of an adult person through his or her cell phone without his or her consent. This doesn't mean that it's illegal to track a person at all; it just means that you need that person's permission.
