The Apple Watch Series 3 has been available for customers in Thailand for quite some time now, but only in the WiFi + GPS model.
It looks like that will be changing in the early stages of April, though. As first reported today by MacRumors, and based on Apple’s own page dedicated to availability for the cellular version of the Apple Watch 3, that model will be landing in Thailand on Thursday, April 5. Customers in that region will be able to buy the new cellular-enabled smartwatch via TrueMoveH.
Once the Series 3 with LTE launches in Thailand, that means the Apple Watch variant will be available in more than a dozen countries and territories, including the United Kingdom, the United States, Japan, Singapore, Switzerland, France, Germany, and others.
Of course, the standard WiFi + GPS model is more broadly available, as that does not necessitate the requirement of wireless carrier support in regions.
