Summary · why it matters

Lleida.net said its SMS traffic delivered to Spanish operators has risen 40% since January, driven by mandatory sender registration. The growth accelerated with the first steps of the regulation and soared after it took full effect on 15 September, with Spain the main destination for the company's SMS traffic. Lleida.net estimates its market share at between 20% and 25% of quality SMS traffic in Spain, the transactional, non-advertising traffic such as two-step verification codes and notifications, a share it was able to calculate thanks to sender registration. Under Order TDF/149/2025 and CNMC Circular 1/2026, operators must since 15 September block SMS, MMS and RCS messages whose sender is a trade name or alias not entered in the CNMC's Alias Register, or that arrive through a provider not authorised in that register, a measure aimed at curbing smishing. CEO and founder Sisco Sapena said requiring every sender to be identified restores trust in the channel and rewards companies that operate legitimately. Lleida.net, a telecommunications operator with its own CNMC-assigned numbering that it can assign to clients, said the register has also boosted activity among its clients, who increased their traffic with the company after registering their senders.
