# Restrictions and limits

{% hint style="warning" %}
There are no limits from our service. However, we recommend reviewing the limits of the Telegram messenger for phone numbers.
{% endhint %}

Sending limits depend on the level of trust Viber has in your number. 

**Recommendations for sending:** 

* If the number is new, blocking may occur after the 5th message per day. 
* If you haven't had any previous correspondence with your contacts, we recommend no more than 20 new dialogues per day. 
* If the client has replied to you at least once in the chat, there are no restrictions on sending. 
* If the client marks your message as spam, it can lead to blocking the number. 
* If your number has been blocked by Viber before, be aware of the limits as a new number to avoid being blocked again. 
* If your phone number was previously blocked, then changing your Viber number increases the chances of getting a block on your new number.

{% hint style="danger" %}
Blocking may occur due to unusual activity on your number. To avoid this, do not exceed the limits for initiating messages and do not send spam.
{% endhint %}
