People aren't writing novels on their SmartPhones. The typed input from a normal volume of text messages, e-mails, and URLs is actually pretty minute when you think about it. Certainly it would be compressed before being uploaded to their servers. IIRC they cite 140 million active devices so if you figure 3kB per day, which is probably on the high side, that's only 400GB before compression. You can compress text down by about 90% these days. That works out to only 44GB of data uploaded per day.
