I just purchased the Spitz GL-X750 with the EP06-A modem as a backup and travel router and wanted to find out why this router has consistently lower connection speeds then my other router with MC7455 modem. Then I noticed when I issue the AT+QCAINFO the EP06-A response with ERROR. Is this modem not provisioned for CA?
Shouldn’t this modem be able to achieve same download speeds as the MC7455?
This is tested with a T-Mobile unlimited and unthrottled data plan. I also added in the custom firewall rules a TTL=65 setting so that TMO doesn’t throttle due to tethering issue.
