This is a point of weakness. Alternatively, a more protected route is hardware encryption. This encryption is over the cellular system rather than needing mobile data. It is established phone...
The fact that the processors for computers and mobile phones contain some amount of gold is an old issue, and the amount is very small. It is used because gold is an excellent conductor of electricity. But now there is no need for that because we have processors made of silicon, copper or aluminium, as a specialist has told us.
