Our corporate policy doesn't allow personal phones to be linked to corp accounts, for obvious reasons. We have no idea what kind of security your personal phone number has setup, nor do we compensate employees for their personal phones, nor do we want corporate communications happening on your personal device (work/life separation).
If the vendor is unable to comply, all we're using them for is email. Time to look elsewhere.
