Which Canadian cellular carrier are you trying to use? https://docs.modalai.com/lte-modem-and-usb-add-on-v2-datasheet/#radio-specification ## Reply by Chad Sweet (ModalAI staff) · 2021-01-14 05:57:14 UTC This page seems to have good information: https://www.signalbooster.com/pages/what-are-4g-lte-frequencies-bands-of-telus-rogers-bell ## Reply by Chad Sweet (ModalAI staff) · 2021-01-14 05:58:20 UTC VOXL-ACC-LTEH-7610 seems like it should work on each of those carriers ## Reply by Aldo Castro Freire · 2021-01-14 13:28:32 UTC Yes, thank you I am trying to use a rogers SIM CARD, So I should order the LTE modem with the US Carrier (WP7610) right ? ## Reply by Aldo Castro Freire · 2021-01-14 13:32:04 UTC Should I be worried that the US carrier does not cover B7 band? ## Reply by Aldo Castro Freire · 2021-01-22 16:57:05 UTC I got the modem but, i am not sure it is working. I don't get any ip ## Reply by Chad Sweet (ModalAI staff) · 2021-01-22 17:05:00 UTC Have you followed the instructions? https://docs.modalai.com/lte-v2-modem-manual/ Also, you will need to know the APN for your carrier and set it properly. You can look at the voxl-modem source code for how to set the APN ## Reply by Aldo Castro Freire · 2021-01-22 17:09:58 UTC Yes I followed the instructions. Yes I know the apn carrier of my provider. I used before. Also my wifi set up is on does it matter? ## Reply by Aldo Castro Freire · 2021-01-22 17:17:26 UTC This is the apn I used: just type ltemobile.apn When it ask for it in the configuration. https://www.rogers.com/customer/support/article/rogers-lte-apn-settings ## Reply by tom (ModalAI staff) · 2021-01-22 17:20:48 UTC (in reply to Aldo Castro Freire) @Aldo-Castro-Freire Can you post the outputs of both `systemctl status -l voxl-modem` and `ifconfig` ## Reply by Aldo Castro Freire · 2021-01-22 17:29:58 UTC these are the outputs: ![5ec57739-dd9c-4970-87b5-21e26c4abafb-image.png](https://forum.modalai.com/assets/uploads/files/1611336583593-5ec57739-dd9c-4970-87b5-21e26c4abafb-image.png) ## Reply by Aldo Castro Freire · 2021-01-22 17:32:33 UTC (in reply to Aldo Castro Freire) wait the first one changed: ![d1249b29-2db4-4450-9ab6-d1ee188a0fc8-image.png](https://forum.modalai.com/assets/uploads/files/1611336683298-d1249b29-2db4-4450-9ab6-d1ee188a0fc8-image.png) ## Reply by tom (ModalAI staff) · 2021-01-22 18:05:28 UTC Have you tested this SIM card previously? With another phone perhaps to determine that it is activated correctly? ## Reply by tom (ModalAI staff) · 2021-01-22 18:18:41 UTC Antoher thing to try is to disable the modem startup script using `systemctl disable voxl-modem` and then rebooting your voxl. After you reboot, ADB back in and run `voxl-modem-start.sh`. This should allow you to see the script's entire output. ## Reply by Aldo Castro Freire · 2021-01-22 18:43:13 UTC okay that worked, one more question for the openVPN I am new to yocto linux, how do I know if the daemon was able to connect to the openVPN server, my IP still the same. ## Reply by tom (ModalAI staff) · 2021-01-22 20:06:02 UTC OpenVPN will usually create a new network interface, similar to `tun` or `tun0` and should route traffic through there. If you run `ifconfig` you will see a list of network interfaces. You will also need to make sure that OpenVPN is starting after you have connected to the internet as it will most likely fail to connect to the VPN and not retry with default settings. ## Reply by Aldo Castro Freire · 2021-01-24 00:06:01 UTC (in reply to tom) @tom thanks apparently the openvpn version needed to be updated the default version that comes with voxl does not work for me ## Reply by modaltb (ModalAI staff) · 2021-01-24 17:10:03 UTC (in reply to Aldo Castro Freire) @Aldo-Castro-Freire thanks for the feedback, do you mind sharing the openVPN Client and Server versions you ended up using that worked? We've tested using server v2.4.8, voxl-vpn (v2.1.3 inside that), and OpenVPN Connect ver 3.2.2 on Adroid.
