T-Mobile blocks Twitter? (updated 12/14/07 9:17 PM CST)
After several days of no Twitter SMS service I contacted T-Mobile customer support. After the standard technical support for my phone (even though ALL phones on my account are denied access to Twitter SMS via 40404) …
Context & Ripple Effects
The Alternageek report lands the same day as TechCrunch's writeup of the same complaints, so this is now a two-outlet story rather than one blogger's support ticket: T-Mobile customers say every phone on their account is denied Twitter SMS via short code 40404, with gripes piling up on the carrier's own user forum. The claim is still unconfirmed by T-Mobile itself, and the reporting treats it as exactly that — reported, not admitted.
The episode fits a pattern already flagged in June 2007 coverage of carriers' unease with services that ride their networks for free, and it matters because Twitter has become real distribution: the author's own blog logged more than 2,000 referrals from Twitter in the past 30 days, so cutting SMS cuts a growth channel, not a toy.
First-order effects
- T-Mobile subscribers on affected accounts lose tweet delivery over SMS immediately, and per the report get no fix from standard technical support even when every handset on the account shows the same 40404 failure.
- Twitter loses an entire carrier's worth of its most habitual usage pattern — SMS in and out — for those customers, pushing them toward whatever non-SMS access paths they can find.
Second-order effects
- Other carriers now face the same question in public: whether short-code partners like Twitter are billed, blocked, or carried neutrally, and silence reads as policy once one carrier is accused of blocking.
- For Twitter, dependence on carrier-controlled SMS pipes becomes a visible single point of failure, strengthening the case for direct client apps and mobile-web access that bypass the short-code gatekeeper.
Third-order effects
- If carriers treat third-party services as negotiable access rather than neutral transport, wireless becomes the front line for the open-access fights that defined the wired net — with short codes and handset platforms as the choke points.
- Service providers that grow up on SMS distribution learn to treat carrier relationships as infrastructure risk, accelerating the shift toward smartphone clients where the OS vendor, not the carrier, controls the pipe.
The trend: Wireless carriers are asserting gatekeeper power over which third-party services reach their subscribers' handsets, forcing fast-growing mobile services to route around the SMS pipe.
