The story circulating is that Anatel suspended TIM’s call blocking. It is the other way round: TIM got Anatel’s rule suspended.
Anatel’s president granted TIM a partial and temporary suspension on 8 September of a provision the regulator itself adopted in August, governing how mass calls originating on mobile networks are filtered.
What the Rule Said
On 17 August 2026 Anatel adopted a ruling that barred operators from exempting mass calls originating on mobile networks from their anti-spam filters. In effect it forced those calls to be filtered like any other.
TIM challenged it, arguing that the provision lacked technical justification and that it treated calls originating on mobile networks more harshly than calls originating on fixed lines.
What Was Granted
On 8 September, Anatel president Carlos Baigorri granted a liminar, a partial and temporary suspension of that specific provision, while the challenge is considered.
This is narrow relief. It suspends one provision, not the anti-spam framework, and it does not decide the argument. The full council will rule on the merits.
The Direction Matters
Summaries of this story have inverted it, describing Anatel as having suspended TIM’s mass-call blocking. That is the opposite of what happened.
The regulator wrote a rule requiring more filtering of mobile-originated mass calls. The operator objected. The regulator’s president suspended his own agency’s provision pending review.
Underneath the procedural detail is a genuine technical question about whether the network of origin is a sensible basis for filtering, given that mass callers can choose which network to originate from. That is what the council will have to decide.
