For non mobile stores, servicing/activating mobile phones is not our job, and leaders don't expect us to be spending time on it. Now, personally, I will help if its a basic problem that I can solve relatively quickly, but that's an exception, not an expectation. For example I move SIM cards from old phones to new phones all the time so that the guest can begin using the new phone, but when activation is required that's when they have to call the company or visit a mobile store. And no, I'm not tying up the electronics phone for them to use.
