Hi @benedettim,

Welcome to our community!

1. Are you referring to the RV55 router? What Aleos version and Radio module firmware are your RV55 and MP70 running?
2. Please make sure you have connected antennas to those routers. Two antennas are required when connecting to an LTE network.
3. What APN have you set up for each router?
4. Could you please share the log files and Template files with me.
5. Additionally, there is a topic related to the APN on Verizon SIM cards, please refer to: [GX440 and change to Verizon static/public IP](https://forum.sierrawireless.com/t/gx440-and-change-to-verizon-static-public-ip/12851)

Thanks,
