A virtual number is the cheapest way to register an account and the most common way to lose one. The mechanism is not obvious until it happens to you.
What happens to the number afterwards
Disposable-number services rent the same number out repeatedly. Sooner or later it goes to someone else, who registers their own Telegram on it and receives a login code. Your account either drops off or leaves with them, message history included.
You do not control when this happens. The account lives until the number is needed again.
The second risk: prior history
A number rented ten times before you has been used for who knows what. An account registered on it is sometimes limited immediately after first login — not for your behaviour but for someone else's record.
The third risk: no recovery
Recovery codes go to the number. No number, nothing to recover — see recovering a locked account.
When a virtual number is fine
When the account is deliberately disposable: a one-off task, a test, checking whether an idea works at all. For an account meant to run for months and carry traffic, saving on the number is the most expensive saving available.
What reduces the risk
- Long-term rental instead of one-off. The number stays yours while you pay, which is a different arrangement entirely.
- Two-step verification straight after registration. A code alone no longer gets anyone in — two-step verification.
- A live session on a device you control. While it exists, login codes arrive there — Telegram sessions.
- Region agreement. A number from one country behind a proxy in another is one more reason to be looked at — testing a proxy.

How Neurogram does this
Everything above is manual work that runs into the number of hours in a day. Neurogram does it on your own accounts and without you: it collects channels and audiences, writes comments and replies with a language model, and keeps limits and quiet hours so the accounts survive.
