Some interesting wireless market updates:

• The strongest growth continues to come from Verizon, accounting for almost 31% of industry’s data revenue in Q307. Its data service revenues jumped by 11% Q/Q to $2B (again becoming the first US carrier to get past the $2B milestone). Verizon was followed by AT&T at $1.8B, Sprint at $1.2B, and T-Mobile at $676M
• The top three US carriers again maintained their respective rankings amongst the top 10 global carriers in terms of data revenues. For the year, Verizon with $5.4B, AT&T with $4.95B, and Sprint with $3.7B in service data revenues stood at #4, 5, and 6 respectively with Verizon closing in on KDDI for the number 3 spot. Verizon became one of only four operators in the world who are now generating $2B or more in data revenues/quarter (the other three are NTT DoCoMo, China Mobile, and KDDI). The carrier indicated that enterprise services such as data card and mobile email are generating in excess of $500M/quarter now.
• iPhone became the quickest smartphone to eclipse the 1M mark in a quarter (by doing it in its first full quarter). By contrast, RIM took 22 quarters or 5.5 years to crack the 1M/quarter sale mark. Palm is still searching for the elusive milestone and might not find it in this lifetime. iPhone also made its entry into Europe and remains in intense negotiations with operators worldwide.
• In terms of messaging, T-Mobile keeps their users more engaged than other carriers. Each T-Mobile subs exchanged on an average 758 messages last quarter compared to 584 messages by a Verizon sub and followed by 370 messages by an AT&T subscriber. By comparison, subscribers in Philippines engage in almost 2000 messages every quarter or pretty much a message every hour.
