# Why is SMS verification not working?

This article explains the SMS verification limits in Onde.Light and what to do if a number or device gets blocked.

To protect the platform from fraud and abuse, Onde.Light limits how often SMS verification codes can be requested in the Driver app and Customer app.

### Rule 1. SMS request limit

A user can request an SMS verification code up to **5 times within 24 hours**. This limit applies per account, installation, or device. After the fifth attempt, further SMS requests are blocked for 24 hours.

**What to do**  
Wait 24 hours before requesting a new code again.

### **Rule 2. Number of phone numbers used on one device**

One device can be used to log in with up to **3 different phone numbers within 24 hours**. If a user tries to log in with a fourth number, the device is blocked for **30 days**.

**What to do  
**Contact [Onde.Light Community](https://community.onde.app/) and ask them to unblock your device.

**What users will see**  
If one of these limits is reached, an error message will appear on the screen. The image below shows an example of this error.
