6. Answers from ATT Customer
Service
Paraphrasing:
– “You can only use wifi for Facetime if you do
not have Mobile Share”
– “You can use Wifi or Mobile Share if you have
Mobile Share.”
– “Cellular Facetime is an added-benefit of
Mobile Share plans”
• “Cellular Facetime is a promotion for Mobile Share”
(Nevermind, comment redacted)
Small Footnote: Mobile Share and Unlimited Data are both LTE data services. 6

Calculation: Unlimited users will have to have a limited talk/text plan which is roughly $45 difference from the shared plans.
Shared plan users also get unlimited talk/text. Prices have been roughly adjusted based on the common talk and text usage. 8

10. Unscientific Answer

See complicated diagram above.

11. Scientific Answer
ATT will suffer severely high
network utilization and high
operating costs if a large
percentage of customers Facetime
non-stop.
– This is a semi-likely scenario since
only nerds have unlimited data at
this point
• Given how many hoops I had to jump
through when ordering iPhone5
– Despite waking up at 3am EST to do it.

12. Scientific Solutions
• Why not limit cellular data usage for
Facetime for your paying customers to
roughly that of 1 or 4gig Mobile Share
plans
– Apple won’t allow it?
• Your unlimited data users are your most
loyal customers, be honest with them.

13. Consumer Guide: How to Seek
Revenge
• Jailbreak iPhone5 (when available).
– turn iPhone5 into an LTE router
• Watch StarTrek: The Next Generation on
Netflix indefinitely.
• Pandora and Spotify your life.
• Fring a reality show.
