If you get at least one unknown call per day from a number saying, “You left a request…” — even if you never left anything — then this topic concerns you directly. Starting from October 2, mobile operators in Ukraine officially received the right to block numbers that are considered sources of spam. It is presented as a victory against phone advertising, but let’s see if it’s really that simple.
For those who want the essence immediately
Yes, now you can report a number, and the operator has the right to block it. But:
— operators will not look only at complaints, but also at call statistics;
— if a number makes many short calls to different recipients, it can be blocked even without complaints;
— this applies not only to “English schools” but also to courier services, pizza delivery call centers and even some banks;
— yes, theoretically it’s possible to abuse the system and try to knock competitors off the market by generating complaints.
Now in detail.
How blocking will work — in plain language
The operator will not listen to call recordings. It is enough to look at statistics: how many calls, what is the average duration, whether people call back, how many unique numbers were contacted, and whether there are signs of an automated voice message.
If at least two criteria match, the operator can limit the activity of the number. And this is not a theoretical possibility — they already have filters similar to email anti-spam systems. First — a warning, then — a block. It is possible to restore a number, but not instantly.
A typical situation that is recognized as spam
A number you don’t know calls. You pick up — there’s an automatic voice: “Good afternoon, our manager…” — you hang up. If this happens dozens of times a day and people either do not talk or hang up at the 10–20th second, the system sees this number as suspicious. A few complaints on top of that — and such a number risks disappearing from the network.
Why regular users will be happy
Because what is happening now annoys everyone. Constant calls like “You have a request…”, “Do you want crypto investments…”, “English in 4 weeks…” — all of this can decrease drastically. A real mechanism of response has appeared, no need to file police reports or prove anything — you just inform your operator, and the process is launched.
But there is another side — the one not mentioned in press releases
These algorithms were designed not for people but for formal indicators. And here the problems begin. For example:
— A courier service calls clients about delivery. Calls are short: “I’ve arrived, please come out.”
— An online store calls to confirm an order: also a short conversation.
— A bank calls about transaction confirmation, the client does not pick up — many missed calls.
— Authorization services call to dictate a confirmation code.
And all of this can look like spam in the system: short calls, different recipients, half of the calls not answered, some calls automated.
Can the new rules be abused
Theoretically — yes. Scenario: an organized group submits dozens of complaints about a competitor's number. If the system sees that the number already has a “suspicious” pattern (short calls + many different contacts + few incoming calls), then the operator has enough formal confirmation — and the number is blocked. The competitor is left with a call center but no connection. Now add to this the long unblocking procedure through the regulator.
Why this may become a problem for businesses
Many small companies, delivery services, call centers and services now work simply: they take a SIM card, put it in a GSM gateway, and hundreds of calls go from it. From the perspective of the new rules — this is almost guaranteed spam. Real companies will now have to prove that their calls are legitimate. That means extra time, resources and communication with operators in an already stressful situation.
How businesses can avoid being blocked — realistic steps
— The number must accept incoming calls. No “outgoing only” numbers.
— A real human operator should be available, not only a recorded message.
— It is worth documenting customer consent for calls.
— If a business uses a call center, it is safer to have records that clients submitted their number voluntarily.
— After the first suspicion or complaint, it’s better not to remain silent but to immediately communicate with the operator before the number gets blocked.
The most interesting question — will this actually change anything for users
Yes, it will. Not instantly, but spam will decrease. Operators have long wanted to launch these filters but were waiting for legal cover. Now they have it. The first mass blocking of “grey” call centers is only a matter of time. But together with them, perfectly legal services that simply have a similar call profile may also be affected.
Questions people will start asking
— Can you block a bank if it calls five times a day?
You can file a complaint, but banks have legal CRM logic, accept incoming calls and hold a conversation for more than 60 seconds. So they won’t be cut off automatically.
— What if an English school calls three times a day?
If there are many complaints and the call pattern is typical — yes, the number can be disconnected.
— Will big call centers bypass the system?
Yes, they already know how: real phone lines, incoming call acceptance, no pure automated messages, increasing minimum call duration to over 60 seconds. They will adjust scripts to fit within the rules.
— Will those “investment companies” with recorded voices be cut off?
Yes, and quite fast. Voice bots are first in line for removal.
Final thought
This is not just about fighting spam. This is a redistribution of the telephone market. Grey schemes will go away, mid-tier companies will be forced to adapt, big ones will find a way. Regular users will indeed breathe slightly easier, but businesses will have to become more formal or risk daily disconnections. And yes, this mechanism can be used as a pressure tool — and it will be used.
