Quick answer
In Phuket, mobile data matters most between the beaches and on tour days: booking Grab from Kata to Patong, checking pier times for Phi Phi, or finding your tour pickup. A local True–DTAC eSIM covers the island’s towns and beaches, and signal drops only far out at sea.
Where will I use data in Phuket?
Resort Wi-Fi is often good in the lobby and weaker by the pool or beach. You will want mobile data for Grab and Bolt between beaches, Smart Bus times, restaurant maps, and messages from tour operators about pickup times.
Does the eSIM work on boat trips to Phi Phi and Phang Nga Bay?
Near the islands and close to the coast you usually have signal. In open water between islands it can drop for a while. Screenshot your tour voucher, pickup time, and pier name before the boat leaves.
Which plan suits a Phuket holiday?
A one-week beach trip with maps, messages, and social media fits the 7-day 15 GB plan. If you upload a lot of video, share a hotspot, or stay longer, choose the 15-day or 30-day Unlimited + Calls plan.
