Alternate to set up two-step if SMS short codes blocked?
Facts:
- To prevent spam expenses, my corporate mobile plan blocks all SMS short codes.
- Setting up two-step verification for Apple ID requires receiving a verification code that is (currently) sent from Apple using an SMS short code.
- There is zero chance that the administrator of my mobile plan will unblock SMS short codes across the board for any period of time.
Given the above facts, which of the following three options (or maybe another one you know of?) is most likely to allow me to set up two-step verification:
- Find which SMS short code(s) Apple sends verification codes from and unblock only those short codes. KB HT5593 "Apple ID: About two-step verification and SMS" lists the supported mobile carriers; does anyone know Apple's SMS short codes for those carriers?
- Have Apple ID send the verification code from a regular, non-short code SMS number like Yahoo! does?
- Have Apple ID deliver the verification code using a voice call like Google does?
Thank you. I'm looking forward to Apple ID catching up with other cloud services.
