When you try to send data > Ethernet Frame default MTU (1500) the SIM7600 responds with CIPERROR 3. This method is used too by the HTTPClient interface, so you can't send POST or other HTTP queries that exceed that size. This PR fix that trying to split the full data array into chunks.

You can see on the SIM7600 AT commands manual: That the limit is 1500.
