Question

When the connection to LTE is dropped, I'm moved to the WCDMA (3G) network. When LTE becomes available again, I'm still stuck in WCDMA over a period before switched to LTE. Can this switch be made faster?

Solution

The switch between technologies is decided by the operator. The general rule is that a switch shall not be made unless it's needed, for example, loss of connection. When the module have a WCDMA connection with an ongoing stream of data, and LTE becomes available, the operator wants the stream of data to end before a switch is made.
