Hi folks,<br>
<br>
I have one of the original production OVMSv3 modules, with the
then-current 3G modem. I've been getting by with Wi-Fi at home, and
the one or two cell sites around town that still seem to have
connectivity, but those sites are gone now too. What is involved in
upgrading to the new modem?<br>
<br>
Do I simply get the modem, or do I need a whole new module? What
about the SIM? The status page reports:<br>
<blockquote>Version: 3.3.003/ota_1/eap (build idf
v3.3.4-848-g1ff5e24b1 Sep 1 2022 08:40:30) <br>
Hardware: OVMS WIFI BLE BT cores=2 rev=ESP32/1; MODEM SIM5360<br>

I'm using a Hologram SIM, and I'm in North America (California USA,
if that matters).<br>
<br>
Thanks,<br>
<br>
Greg<br>
