**Quick answer:** For two to four weeks based in Ao Nang with trips to Railay, Phi Phi and Koh Lanta, buy an unlimited Thailand eSIM for 15 or 30 days before you fly. As of 25 October 2026, Fizen's Thailand plans run on TrueMove H over 4G and 5G, and the unlimited plan's speed is capped at 10 Mbps. On the water, signal comes and goes between islands, so save ferry tickets and offline maps before you board.

**Key takeaways**

- **Unlimited suits island weeks.** Photo uploads, ferry apps and maps add up. The Thailand unlimited plan comes in 3 to 30 days, capped at 10 Mbps, as of 25 October 2026.
- **Railay is boat-only.** Longtails from Ao Nang cost about 100 baht one way and run roughly 8am to 6pm, per Backpackers Wanderlust.
- **The monsoon cancels boats.** From May to October, Andaman ferries are frequently cancelled or delayed in rough seas, especially June to September, per Wego.
- **Carry small cash for markets.** Most Krabi night market vendors do not take cards, per Traveloka; the phone line is for maps, tickets and rides.

You are on the beach at Railay at 5.40pm, the last longtails are filling, and the guesthouse wants the Phi Phi ferry ticket confirmed tonight. The PDF is in an email you never downloaded. Krabi rewards people who plan for the gaps: the cliffs, the crossings, and the island cafe whose Wi-Fi gave up an hour ago.

## How do you stay connected while island hopping from Krabi?

Install a Thailand eSIM at home on Wi-Fi, keep your home SIM in the phone for bank SMS, and switch the travel line on after landing at Krabi airport. Then prepare for the water: download offline maps of Krabi, Phi Phi and Koh Lanta, save ferry tickets and hotel confirmations as screenshots, and send anything important before the boat leaves the pier. Signal at sea depends on the towers on the mainland and the larger islands, so it comes and goes as you cross.

## Which Thailand eSIM plan fits a Krabi trip?

As of 25 October 2026, Fizen's Thailand-only plans connect to TrueMove H on 4G and 5G. The unlimited plan is capped at 10 Mbps, which comfortably carries a 720p call (Zoom lists 1.2 Mbps each way), and the 3 GB and 10 GB plans state no throttle. Current prices are on the shop page.

| Your trip                            | Plan that fits     | Why                        |
| ------------------------------------ | ------------------ | -------------------------- |
| 3 to 5 days, Ao Nang and Railay      | Unlimited, 5 days  | Short and photo-heavy      |
| A light week, one island trip        | 10 GB, 7 days      | About 1 GB a day           |
| Two weeks with Phi Phi and Koh Lanta | Unlimited, 15 days | Uploads and hotspot add up |
| A month working from Ao Nang         | Unlimited, 30 days | Calls and a laptop hotspot |

Continuing to Malaysia or Vietnam? The Asia regional plan covers 18 countries, uses AIS 5G in Thailand and slows to 128 kbps after its data is used. Plans cannot be topped up, so more data means a new eSIM.

## How much data does an island-hopping day use?

| Your day                                            | Estimated GB |
| --------------------------------------------------- | ------------ |
| Ferry day: tickets saved, offline maps, messages    | 0.5          |
| Beach day with photo and short video uploads        | 1.5 to 2     |
| Work day in Ao Nang with calls and a laptop hotspot | 3 or more    |

These are our estimates. Two weeks mixing those days runs past 20 GB, which is why unlimited beats fixed data for most island trips. A light week of about 1 GB a day fits 10 GB for 7 days.

## Where does Krabi island hopping get tricky?

- **Railay has no road.** Longtails leave Ao Nang Beach or Ao Nam Mao, run roughly 8am to 6pm and cost about 100 baht one way, with a 50 baht surcharge after 6.30pm, per Backpackers Wanderlust. Book the evening ride back while you still have signal.
- **Monsoon crossings.** Wego's July 2026 guide says boats between Phuket, Phi Phi, Koh Lanta and Koh Lipe are frequently cancelled or delayed when seas turn rough, especially June to September. Check the operator the morning you travel.
- **Island Wi-Fi is fine until a storm.** Nomada puts Krabi internet at 50 to 200 Mbps, but patchy during typhoons, and counts only a handful of coworking spots in Ao Nang. Your phone line is the backup.
- **Markets want cash.** Krabi Town's walking street runs Friday to Sunday evenings on Maharaj Soi 10, and the Chao Fah Pier market runs nightly, per Traveloka. Bring small notes.

## When is a local Thai SIM better for Krabi?

If you stay longer than a month, or you do not mind queueing at a counter on arrival, a local SIM is a fair choice. True's tourist SIM terms require registration with a valid passport, allow up to three SIMs per brand, and cap validity at 60 days. An eSIM installed at home skips that queue and is working before you reach the longtail pier.

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.

Sorted, the trip looks like this: the Phi Phi ticket opens on the pier, the longtail back is booked before the cliffs swallow the signal, and the evening is pad thai at the Chao Fah market with small notes in your pocket.

## Frequently asked questions

#### What is the best eSIM for Krabi island hopping?

An unlimited Thailand plan for the length of your stay, on TrueMove H and capped at 10 Mbps, as of 25 October 2026\. For a light week, 10 GB for 7 days fits.

#### Do I need data on the ferry to Phi Phi?

Not if you prepare. Save tickets and offline maps before boarding, because signal comes and goes on the crossing.

#### How do I get to Railay from Ao Nang?

By longtail boat only, about 100 baht one way, roughly 8am to 6pm, per Backpackers Wanderlust.

#### Can I top up a Thailand eSIM?

No. Most Fizen eSIMs cannot be topped up, so buy a new eSIM if you need more data.

#### Is Krabi good for digital nomads in the rainy season?

It is quieter and cheaper, but May to October brings ferry cancellations and patchy Wi-Fi in storms. November to April is the dry window, per Nomada.
