In addition to their publicized disclosure of iPhone plan prices for individual customers, AT&T and Apple have also released pricing details for family phone users and existing AT&T customers. Family plans start at $80 and all have unlimited night and weekend minutes, 200 SMS Text Messages, and the same unlimited data features as individual plans. The $80 plan includes 700 minutes, while $100 (1400 minutes), $120 (2100 minutes), $160 (3000 minutes), $210 (4000 minutes), and $310 (6000 minutes) plans offer correspondingly more time.
The company also added that existing voice plan customers can add an iPhone data service plan for an additional $20 per month with 200 SMS Text Messages. Paying $10 more ($30 total) will increase the SMS number to 1500, or $20 more ($40 total) will increase the SMS number to unlimited.
