T-Mobile puts the blame for its anemic prepaid growth on AT&T (updated w/ AT&T statement)
T-Mobile posted a very good last quarter, but noted a stark decrease in prepaid subscribers, pretty unusual for the Un-carrier. The user base for its prepaid offers increased with 149,000, a far cry from the 260,000 posted in Q3. Compare that to the sequential growth in postpaid subs, from 595,000 to 891,000, and you'll see what got T-Mobile worried, not to mention the fall from 541,000 net prepaids in Q4 2016.
The Un-carrier parsed the stats, and found out that the culprit for the nosedive in prepaid subscriber growth was... AT&T. At the time, AT&T was running a clever bring-your-own-device (BYOD) promo in select areas, aiming to simplify the porting process for switchers that come from another carrier. BYOD campaigns don't require such stringent financial history checks like buying phones on installments, as there is no credit extended, just prepaid monthly plans that can be cut without loss at any time, if the user stops paying.
That's the analysis that T-Mobile's CFO Braxton Carter put out at an investor conference yesterday, hinting that things with AT&T's miraculous 329,000 post paid subscriber growth after a few quarters of losses, may not be as rosy as they seem. In fact, the CFO claims that the carrier's porting ratio against AT&T and Verizon has since increased significantly, to 1.7 net adds for each subscriber lost, so we can't wait to see the Q1 results reported by all carriers.
