Movistar has reached a new milestone with ‘Spam Calls’ (Llamadas Spam), the feature launched last March to protect users from unwanted calls, with 1.2 million lines now having proactive call blocking activated by customers.
‘Spam Calls’ has therefore become the fastest-adopted service ever launched under Telefónica’s commercial brand, reflecting users’ growing concern about unwanted interruptions and the need for tools that enhance their security and peace of mind in their everyday mobile use.
With ‘Spam Calls’, Movistar automatically identifies and flags communications on customers’ devices that may be considered unwanted, including spam calls, calls displaying spam-like patterns or calls already reported as a nuisance by other customers. Users therefore receive an on-screen warning whenever an incoming call shows signs of potentially being unwanted.
In addition, customers can use the service to activate full blocking of spam calls through the Mi Movistar app, the telephone customer service channel or Movistar stores, preventing these calls from reaching their mobile phones altogether.
Since ‘Spam Calls’ was launched on 16 March this year, Movistar has identified 166 million spam calls and blocked more than 15 million at the request of customers who activated the blocking feature so that these calls do not even ring on their mobile phones.
Blocking fraudulent calls to strengthen digital security
‘Spam Calls’ complements the measures Telefónica has been implementing since March 2025 to block malicious fraudulent calls at network level, including calls using fake or manipulated phone numbers, in line with Ministerial Order TDF/149/2025, aimed at combating telephone fraud in Spain.
Telefónica was the first operator to implement these anti-spoofing measures, ahead of the regulatory deadlines.
Since the Ministerial Order came into force in March 2025, Telefónica has blocked more than 241 million fraudulent voice calls and more than 28 million fraudulent SMS messages.
