M66 gprs http or gsm connection lost by moving

We are working on a tracker (we use the M66 module), which transmits data to the server using HTTP and POST requests (according to the documentation) with a period of 20 seconds. Everything works well in one place. But when moving, the connection is lost and the module takes a long time (1-2 minutes) to reconnect to the network again. The situation gets worse when traveling by car. We assume that this is due to the change of base stations.

Is there some way to avoid getting disconnected from the network? (seamless recon) Or make a reconnection within 10-20 seconds?

based on your description, your module has done sever cell reselection , we need the detail log for more analisis.
