Hello @JJ1997
It seems to be a low memory issue, not releated to the 4G module, you have to leave enough memory to use for 4G module.
Hello @numbqq, how much memory does the module need at least? Do you know the correct way to set reserved memory? Before I set 32MB of free memory but the error will still show up after one day. (vm.min_free_kbytes = 32768 in /etc/sysctl.conf).
