> Officials told Politico that Kelly had not used the personal phone since joining the administration in January, and has reportedly been using a different phone since. He reportedly relies on his government phone while at the White House.

Then why did he bring it to the White House IT team because it stopped working/updating?

Edit: To clarify, it's not that he took it to the White House IT team (that's appropriate). It's the question of why he would notice if it wasn't working, the type of technical complaint described in the articles seems to argue a little against him not using it at all.
