Following in the footsteps of Verizon Wireless, AT&T announced Wednesday that it has new plans that allow customers to share data. The new plans will be available in late August and start at a cheaper rate than Verizon’s — $40 for 1GB of data, plus $45 for each smartphone versus $50 and $40 on Verizon — but end up being more or less similar in the end. One key difference is that AT&T’s smartphone fee gets smaller as you add more data, whereas Verizon’s fee is always $40. Both companies’ 4GB plans, for example, are $70 for the data, plus $40 for each smartphone. At the top end, AT&T will offer 20 GB of data for $200 and $30 for each smartphone, compared to Verizon’s 10 GB plan that offers the data for $100. Read the full story at The Washington Post.
