A turtle's call sign can only be one, and if you want to apply for a station in another area, you must choose one of two options:
1. Deactivate the original call sign and apply for a new local call sign at the new location.
2. Deactivate the original call sign and apply to use it at the new location (this is practically impossible in practice).
Since the initial call sign was only for use within the province, it was possible to apply for a new call sign from another province. In practice, you could obtain a new call sign directly at the new location without canceling the original one.
However, once connected to the internet, there will definitely be an investigation and appropriate handling of cases where a person has multiple call signs. Therefore, it is still recommended to first cancel the original call sign and then apply for a new one in your hometown, while also setting up a fixed frequency. Additionally, you should apply for a nationwide shortwave license that does not require a fixed location, which can be used for activities outside of your hometown.
