Yes, there is cellphone coverage on Koh Jum, an island in Thailand’s Krabi province. While the island is relatively undeveloped compared to other more tourist-heavy destinations in Thailand, most major Thai mobile network operators do provide coverage there. This means that visitors can generally expect to have access to basic mobile services, including voice calls and data connectivity.
However, it’s important to note that coverage can vary depending on where on the island you are, and some remote areas might have weaker signals or no coverage at all. For those planning to visit Koh Jum, it might be a good idea to check with their mobile operator about specific coverage on the island and consider downloading maps or important information in advance in case of intermittent connectivity.
