Hi,
I am looking for mqtt cloud for free, which can be used normal data packet.

I am corrently using mosquitto on my server, but want using cloud service if it's free:)
I know some cloud for free such as a CloudMQTT, Adafruit IO,ThingSpeak, AWS IoT and etc..but unfortunately all most cloud I know have some issues that are not being used for free anymore,,,or,,has different data format
of course there's a liberally for them but they are not working for sim7600e I am using

anyway,, could you guys recommend a cloud if its for free?

I got the impression that Adafruit IO was pretty good and free. So what's the problem with it?

I used to use Cayenne for MQTT data but ended up using mosquito on a home Raspberry Pi as it's a lot more convenient and avoids the loss of date/control if no internet access.

There is https://shiftr.io/ but it is not private as anyone can see the data

https://www.hivemq.com/ might also have a free (non private) option
