If you want to raise revenue, what's the fastest way? Not cold calling for new customers. Upselling and cross-selling your current base will move the needle a little. But if you have a lot of subscribers the fastest way to raise revenue is to raise prices. BAM!
AT&T sent out notice to business customers about rate increases on Fast Access Business DSL ($5-$10) and POTS service ($5-7). Then give them just a month notice. With the September bill, the new rate will be effective.
Everyone else is worried about pricing. Not AT&T. Leave! We don't care. If they lose less than 10% of subscribers, the price increase will still work out to more revenue next quarter.
