I’ve tried apn settings tweaking and tried several sim card of that gsm career. Then I realised that this particular sim network isnt working with EMLID.
If you tried this SIM card with different Reach devices, it does look like it’s not an issue with a particular Reach.
Reach receivers work well with different types of SIM cards. Usually, such cases are resolved by charging the SIM card settings or configuration. We haven’t tested this particular SIM card operator, but it could be the data-only SIM card. In such cases, some of our users could connect to such SIM cards after mimicking a voice plan with a provider or switching to the voice plan.
