One can sympathize with a President's staff trying to provide him with a mobile device.
Any of a mobile's radios could be used to pinpoint his current location, given knowledge of is unique identifiers; that's probably not cool with his physical protection detail. Such knowledge would also make the mobile a prime target for spoofing AP's, cell towers (BTS simulators work for bad guys just as well as for the government), and websites. Then there's all the Tempest issues with inadvertent radiation.
On top of that, his email, and by connection, all of his contacts, are probably the number one spearphish targets in the world.
I wonder if someone makes a phone has hundreds of link level identities and rotates through them?
