How to Renew Water IoT SIM Data Fees
The 4G water IoT SIM provides cellular connectivity, with data fees charged annually. Expiry without renewal causes devices to go offline, disabling remote control. This article explains how to renew IoT SIM data fees based on YOOAI's Water IoT Solution. See Technical Docs.
1. Data Fee Billing
- Billing cycle: Annual, proportional to device count
- Billing method: Device count x annual data fee
- Applicable hardware: 4G Comm Board BL-600N, 4G+Bluetooth Module
- Wi-Fi option: Wi-Fi+Bluetooth Module has no annual data fee
2. Renewal Channels
1. Contact Sales
Brands contact YOOAI sales with a device list and renewal years to get a renewal plan and complete payment. See Contact Us.
2. Platform Query
View IoT SIM status and expiry in the PC backend to plan renewal ahead.
3. Expiry Handling
- Before expiry: The system reminds in advance (renew 30 days before expiry recommended)
- After expiry: Device goes offline; remote control and data reporting interrupted
- Recovery: Device auto-comes back online after renewal payment-no on-site action needed
4. Notes
- Renew ahead to avoid expiry disconnection affecting operations
- Bulk renewal may get tiered discounts-contact sales
- New devices need IoT SIM data activation in sync
- Retired devices need SIM deactivation to avoid empty data charges
5. Data Fee vs Wi-Fi Option
| Option | Data fee | Fit |
|---|---|---|
| 4G board / 4G+Bluetooth | Annual | Commercial, no Wi-Fi |
| Wi-Fi+Bluetooth | No annual fee | Home, stable Wi-Fi |
IoT SIM data fee is an ongoing cost of the 4G option; timely renewal keeps devices online. See Technical Docs for more; to renew or learn about the solution, contact us.
