US cable MVNOs look to improve multiline and premium traction as mobile share grows

The location broadband marketplace remains a slog for US cablegram operators, with their nett broadband subscriber losses continuing to equine acknowledgment to the two-prong unit from fibre and fixed wireless entree (FWA).

Given the prolonged subscriber losses for cable’s halfway connectivity play, mobile and the accompanying virtues of convergence aren’t a sideline enactment for cable; it’s the full ballgame close now.

In that context, Q3 2025 offered different changeable of bully quality from the cablegram players’ MVNO organisations. Comcast and Charter reported northbound of 900,000 nett mobile enactment additions betwixt them successful the quarter, acknowledgment successful nary tiny portion to Comcast erstwhile again blowing by its idiosyncratic champion quarterly mobile performance. Moreover, each saw much-needed gross maturation from the class – maturation they anticipation to spur connected by driving multiline take-up and much premium relationship mixes.

Comcast saw its champion quarterly mobile enactment tally yet successful Q3 2025, with its 414,000 nett mobile enactment adds during the 4th putting Comcast astatine 8.94 cardinal full mobile lines and implicit 14% penetration of its broadband base. However, CFO Jason Armstrong noted during the company’s Q3 2025 net presumption that “nearly fractional of our residential postpaid telephone connects came from customers taking a escaped line.”

In short, Comcast’s adoption of a free-line bundling mechanic successful mid-2025 played a large relation successful that uptick successful subscriber acquisition. This, of course, is not dissimilar the leap successful nett adhd cadence Charter saw aft uncorking its Spectrum One bundle mode backmost successful November 2022.

Armstrong went on, however, to enactment that Comcast “saw beardown uptake of [its] caller premium unlimited plans, enhancing [its] worth successful the postpaid market.” Comcast volition request Xfinity Mobile to construe a important information of those escaped lines into paying customers erstwhile promo roll-off clip hits successful H2 2026 if the company’s going to seizure the convergence gross maturation it’s targeting.

For that, Comcast hopes newer wrinkles successful its premium tier program – i.e., gigabit-level speeds (thanks to a WiFi boost), 4K HD streaming, higher hotspot allotments, precocious spam telephone protection, and guaranteed instrumentality upgrade capableness with discounts – supply a robust capable postpaid offering to support those subscribers satisfied erstwhile they are paying afloat freight.

The header numbers astatine the apical of Charter’s Q3 2025 study paper amusement the strain from its combined stressors, resulting successful year-over-year (YoY) declines crossed full gross (-0.9%), residential gross (-1.1%), and adjusted EBITDA (-1.5%). While broadband gross was up 1.7%, that’s a flimsy uptick driven by promo roll-offs and pricing actions – an unsustainable look successful the agelong term. Thus, mobile remains Charter’s agleam spot.
