We give simple criteria which characterize the symbols $$$u$$$, $$$\varphi$$$ defining continuous and compact weighted composition operators $$$W_{u,\varphi}$$$ acting between two different weighted sequence spaces. Also we characterize when $$$W_{u,\varphi}$$$ is bounded below and when it has closed range.
