Foreigners choosing between Phuket and Koh Samui are usually trading infrastructure and flights for smaller-island calm — not picking "the best beach."
At a glance
| Factor | Phuket | Koh Samui |

Cost of living snapshot
Both islands cost more than Chiang Mai for equivalent condo quality. Phuket has more budget pockets inland; Samui's hills and resort zones keep averages high.

Visa and admin
National rules are identical. You still need TM.30 from your landlord, 90-day reporting on schedule, and insurance proof where your visa requires it.

Frequently asked questions
Which island is cheaper?
Neither is a budget destination. Phuket offers more price tiers; Samui can feel uniformly resort-priced in prime beach zones.
Can I work remotely from either island?
Yes — fibre is widely available in expat areas. Power cuts and storm season affect both; backup mobile data helps.
Is Phuket too touristy for long stays?
Patong and beach strips are. Inland and east-coast areas feel residential if you choose carefully.
Do I need a car on Samui?
Many long-stayers use scooters or cars for hills and hospital trips. Walk-only life is limited outside small pockets.
