AT&T is rushing to reinforce its MMS messaging infrastructure ahead of the planned September 25 iPhone MMS launch, according to DSLReports. Citing people involved with the launch, the article states that AT&T is “very” nervous about the launch after seeing “record traffic” from the small group of test iPhone users for whom MMS is already active. The company reportedly had a fairly significant outage yesterday that has resulted in the beefing up of their MMSC messaging servers; estimates from those working on the project suggest traffic on AT&T’s network may spike as much as 40% on Friday as newly MMS-capable iPhone users test the feature out. According to the report, the company plans to activate iPhone users in waves, with the first group receiving a mass SMS message at around 10 a.m. Eastern Time, and continuing throughout the day, assuming all goes well.
Update: AT&T has posted a message on its Facebook page, stating that the MMS rollout will begin “late morning” Pacific Time on Friday. The full message reads, “[w]e know you’ve been eager for this service so we wanted to offer a quick update on the launch plans for MMS on Friday, Sept. 25. Late morning, Pacific Time, on Friday, the new carrier settings update enabling MMS should be live and ready to download through iTunes. We’ll provide the steps and all of the details you need right here at that time.”
