Length of Text Messages

Do any of you know how long the text messages can be and how many can be sent/recevied with the current network and infrastructure? Do you the devices have preprogrammed times to receive messages or do they receive messages real time? Thanks for your help and I can’t wait to see how this project develops.

devices receive messages in realtime. But the default long-range settings we use for lora are quite slow. The absolute max packet len is 255 bytes , which equates to about 200 bytes for the max text message length.

Though symbols such as emoji and non-latin scripts are encoded as utf8 so those will consume up to four bytes per symbol.
