Here is the eSIM setup for a month on Phu Quoc, sized for the days the island goes dark. - Author: Quinn Dao - Tags: eSIM, Travel & Nomad **Quick answer:** Flying straight into Phu Quoc from abroad gives visitors of any nationality 30 days visa-free on the island, so match the eSIM to it: a 30-day plan bought and installed before you fly. As of 25 October 2026, Fizen's Asia regional plan covers Vietnam on Viettel 4G, with 30-day options at 5, 10, 20 and 50 GB, slowing to 128 kbps after the data is used. Working from the island? Take 50 GB, because the power grid is rated unreliable and the phone line becomes your backup. **Key takeaways** - **The visa clock and the eSIM clock match.** Vietnam Tourism (updated 14 October 2026): 30 days from entry, island only, any nationality, direct arrival from abroad, no extension. - **The grid is the weak point.** Freaking Nomads (October 2026) measures island internet at 136 Mbps down but rates the power grid as not reliable. Keep phone data for the outage hours. - **The dry season is starting.** Local Vietnam puts the dry season at December to April, with late November often good, and the rainy season from May. - **50 GB for 30 days for a working month.** Coworking spaces are rare on the island and plans cannot be topped up, so the phone line does more of the work. You landed on a direct flight from Singapore, the officer stamped an exit date 30 days out, and the villa in Ong Lang lost power for the second afternoon in a row. The laptop has two hours of battery. The question for the month is simple: when the island goes dark, is your phone line big enough to keep you working? ## How does the 30-day Phu Quoc visa exemption shape the stay? Vietnam Tourism's guide, updated 14 October 2026, says the exemption has no list of eligible countries: you must arrive in Phu Quoc directly from outside Vietnam, without clearing immigration on the mainland, and you can stay 30 days from entry. It covers the island only and cannot be extended. A flight in from Ho Chi Minh City does not qualify. If your month includes Hoi An or Hanoi, you need a Vietnam visa. Vietnam's official tourism site says the e-visa is valid for 90 days with multiple entry and open to citizens of all countries since 15 August 2023. ## What fixes connectivity for a month on Phu Quoc? Buy and install the eSIM at home on Wi-Fi, keep your home SIM in for bank SMS, and switch the travel line on after landing. On the island, use villa or cafe Wi-Fi for heavy work and let the phone line carry maps, Grab, messages and the hours when the power is off. Goats on the Road found Wi-Fi widely available but dedicated coworking spaces rare, with cafes such as Highlands Coffee and Like Coffee in Duong Dong doubling as offices. Freaking Nomads lists Duong Dong, Long Beach, Ong Lang and An Thoi as the best areas to stay. ## Which eSIM plan covers a 30-day Phu Quoc stay? As of 25 October 2026, the Fizen Asia regional plan, which spans 18 countries, covers Vietnam and connects to Viettel Mobile on 4G. 30-day options come in 5, 10, 20 and 50 GB, and after the high-speed data is used, speed drops to 128 kbps: messages still work, video calls do not. Check the eSIM tab in the Fizen app or fizen.io/esim for the current plans for Vietnam, including unlimited options. Current prices are on the shop page. | Your month | GB per day | GB over 30 days | Plan that survives | | ------------------------------------------------------------ | ---------- | --------------- | -------------------------------------------------------------- | | Wi-Fi does most work; phone for Grab, maps, messages | 0.6 | 18 | 20 GB, 30 days | | Above plus an hour of calls on phone data, three days a week | 1.0 | 30 | 50 GB, 30 days | | Above plus 2 hours of laptop hotspot every day | 2.6 | 78 | No fixed plan fits; check unlimited options or use a local SIM | These are our estimates; the call figure uses Zoom's 1.2 Mbps each way for 720p, roughly 1 GB an hour. Most Fizen eSIMs cannot be topped up, so if you run short, the fix is a second eSIM. ## How do you pay on Phu Quoc as a visitor? The island's best food is small and local. Visit Phu Quoc points to bun ken, a fish noodle soup rarely found off the island, goi ca trich, the raw herring salad wrapped in rice paper, and crab from Ham Ninh fishing village. The night market sits in Duong Dong near Dinh Cau temple. Stalls like these rarely take cards, and many show a Vietnamese bank QR code instead. If you are a foreign visitor, Fizen QR Pay can pay those codes from USDT. It covers VietQR bank codes, VNPay, MoMo and ZaloPay, shows the amount in dong before you confirm, and in Vietnam pays only QR codes of Vietnamese account holders. It is funded only with USDT on Solana or BNB Chain, with no bank link, card or VND deposit; USDT on another network, or another token, cannot be deposited. Limits are US$800 per payment and US$1,000 per week, with no daily limit. It is for cross-border use only, so Vietnamese residents cannot use it in Vietnam. The Fizen wallet is self-custody; USDT you move into QR Pay is governed by the QR Pay Terms, so move in only what you plan to spend. ## When is a local SIM the better choice on Phu Quoc? If you hotspot the laptop every day and no unlimited option in the app suits you, a local Viettel or Vinaphone bundle is the better buy, because local plans go larger than any fixed travel plan. You register it in person at a carrier store, which on Phu Quoc means finding one in Duong Dong after you land. For everyone else, the eSIM saves that errand and is running before the plane doors open. If the eSIM fails on Fizen's side, a real person in the in-app chat handles it, and a verified fault gets a free 1-for-1 replacement for the length of the trip, or a refund for the days you could not use. Changed plans? An unused, not-yet-installed eSIM can usually be taken back; eligibility depends on the plan, check Package details or ask chat. Get it right and the month is quiet in the best way: the call holds through the outage, the Grab finds the villa at the end of the lane, and the bun ken is paid before the bowl cools. ## Frequently asked questions #### How long can I stay on Phu Quoc without a visa? 30 days from entry, on the island only, if you arrive directly from abroad.
