My GSM Module has been replaced. What do I need to do to make the new GSM Module work the same as the previous one?

You will not need to do anything. It should continue working the same as with the previous Module. You may want to run a test by pressing the ‘Test’ button on the “GSM Module Settings” screen of the Robomow app (Main Menu ⇢ Lawn & Mower Options ⇢ Mower ⇢ Mobile Comm. System). If everything is intact, you should receive a “GSM Test Passed” notification.
