T-Mobile Won't Tax Twitter Texts But Will Hike Prices
T-Mobile USA finally divulged a little information on its impending pricing change for text messaging, saying the move affects only the messaging aggregators that serve as a kind of middleman between businesses and carriers.
Context & Ripple Effects
T-Mobile USA has spent over a year pulling toward flat-rate pricing, starting with its $50 unlimited calling trial in February 2009. Its impending SMS price change initially looked like a consumer hike — and a report that Twitter messages would be 'taxed' spread fast before T-Mobile denied it.
The company's clarification on September 17 narrows the story considerably: the increase lands on messaging aggregators, the middlemen who connect businesses to carriers for bulk and application-to-person texting. That makes this a business-to-business repricing, not a consumer fee — but it still raises the cost floor for every brand using SMS to reach customers.
First-order effects
- Businesses that send SMS through aggregators — for alerts, marketing, and notifications — face higher pass-through costs from their aggregator providers, effective with T-Mobile's pricing change.
- Twitter and other services whose outbound notifications ride those aggregator pipes are insulated at the consumer level, per T-Mobile's own statement, but their delivery costs depend on how much of the hike aggregators absorb versus pass on.
Second-order effects
- Aggregators must reprice their contracts or squeeze margins, pushing the cost onto the brands and developers building on business SMS — a direct hit to the nascent app-to-person messaging market carriers themselves sell into.
- Rival carriers' own aggregator rate cards come under scrutiny, since any carrier that holds rates steady gains an edge courting the same notification-heavy services.
Third-order effects
- If carriers systematically raise the toll on the SMS middleman layer while flat-rate plans spread, application-to-person messaging economics get decided by carrier pricing rather than market competition — a structure regulators and large messaging platforms have reason to challenge.
- The episode also shows how opaque carrier-to-aggregator pricing is: confusion about who pays forced the carrier to publicly deny targeting a single high-profile service.
The trend: Carriers are shifting SMS monetization from consumer plans toward the business-messaging supply chain, where aggregators absorb and pass through whatever the carriers charge.
