In Telegram groups where the bot has been added, the /check command is available for free checks. It only works in topics linked to a service.
How /check Works
- 01
The bot administrator links a service to a specific group topic
- 02
Users send /check IMEI (or SN, phone number) in that topic
- 03
The bot validates the input format and checks the daily limit
- 04
The result is sent as a reply to the user's message
Limits
| Parameter | Value |
|---|---|
| Default limit | 1 check per day per user per topic |
| Configurable limit | From 1 to 100 checks per day (set by admin) |
| Limit reset | Automatically every day |
| Bot admins | No restrictions, no input validation |
If a provider error occurs, the attempt is not counted - the limit is restored.
Input Formats
Accepted formats depend on the linked service:
| Format | Rule |
|---|---|
| IMEI | 15-16 digits |
| Serial Number | 10-12 letters and digits |
| Phone | 10-13 digits, optionally with + |
| Free format | If the service does not restrict input type |
Banned users cannot use /check.
Setup (for Bot Administrators)
To set up /check in a group, use admin commands:
| Command | Description |
|---|---|
| /setup_service ID [limit] | Link a service to the current topic. ID - service identifier, limit - checks per day (1-100) |
| /setup_services | Link a topic for service update notifications |
| /unlink_chat | Remove all bot links from the chat |
Setup commands only work in topics (not in General). The bot must be added to the group with administrator permissions.
