On the product pages for the Bounce 1 and Bounce 2 watches, it says: "No need to switch phone providers." With our current provider, we have a family plan that gives us up to 4 numbers without extra costs - perfect for two parents + two kids. But the page also says "subscription plan required", which links to an €11/month Garmin plan.
Does this watch take a SIM or eSIM from our existing provider ("no need to switch") and the Garmin plan is just one offer I could consider, or are we required to use that Garmin plan? That was not clear from the product page.
