Hello
1. which sim card to buy for IoT?
The device will send a maximum of a dozen text messages per month.
This is an amateur gadget fitted with a SIM800L and nodemcu module. I am primarily interested in the low maintenance cost of such a card.
2. possibly how to send sms over the internet (nodemcu is online all the time).
