The EZR24 and EZR34(T) series routers use EV4X series firmware. They use the same MediaTek MT7621 architecture with an 880MHz clock speed, 256MB memory, and 32MB flash memory.
The EV4X firmware supports 4G-LTE and 5G-NR modems. It has built-in mobile modem drivers and multiple networking protocols to control the 3G/4G/5G modem and connect to mobile networks.

Firmware Upgrade Tutorial
!IMPORTANT!
DO NOT turn off the power while flashing and resetting the firmware!
If you run a critical upgrade with a leap of several versions, please choose “Local Upgrade” below and unselect the “Keep Settings” option.

- Compare the MD5SUM code and click the “Proceed” button to start flashing new firmware;
- Wait for 5 minutes, then connect to the router by Wi-Fi or LAN, and re-log into the router’s IP address.
Note: If you choose “Keep Settings” on step 3, the router’s password is the same. If you have not kept settings, the default password is none. Click the “Login” button to access the admin panel.
It requires an Internet connection to download the firmware file online. Please make sure your 4G router is connected to the Internet.
- After logging into the router, go to “System > Backup / Flash Firmware” on the top menu.
- Scroll down to the last section of “Online Upgrade.”

Hello
I am a new customer of modem router EZR24-05G i like to understand some possible feature upgrade for this product if is capable or the hardware not allow
Here my tree request
1) Dual sim function will be activated as a backup
2) What kind of mobile connection is connected (5G or 4G LTE or 4G LTE advance)
3) Traffic statistic, Limit threshold, SMS alert
Thank you for your great and valuable advice. We appreciate your interest in new features to improve this product.
1) Dual SIM functionality is hardware-dependent. Unfortunately, the EZR24-05G model only has a single SIM slot for the 5G module. EZR34T series outdoor 5G routers support dual SIM slots and auto backup.
2) The 5G router connects to 3G/4G/5G according to the signal quality. When connected to the 5G-NR network, the front page shows “5G-NR” on access tech.
3) Traffic statistics, thresholds, and SMS alerts are great feature ideas. Our development team is always working on enhancements like these.
Thank you again for your feedback. We aim to provide the best experience for our customers.
