Quick Answer

You’ll get an instant QR by email, follow a short install for iPhone or Android, then enable the eSIM on arrival.

Recommended plans
- Short-trip (3–5 days): 3–6 GB — maps, messaging, light browsing.
- Standard tourist (7 days): 8–15 GB — regular social, navigation, photo uploads.
- Content creators / heavy users (7–14 days): 20+ GB or unlimited options — video uploads, live streaming.
- Families / group sharing: Pick a larger single plan that supports hotspot or multiple eSIMs per device if needed.
Who each plan is best for
- Light user — short day trips, mostly WhatsApp, maps, occasional photos.
- Average traveler — social apps, daily navigation, some video streaming.
- Creator/remote worker — high upload needs, backup connectivity for editing and uploading.
Coverage in Krabi (Ao Nang, Railay, Koh Phi Phi & Krabi Airport)
Expect strong 4G/5G coverage in Krabi town, Ao Nang, and around Krabi Airport. Coverage on ferries and some smaller islands can be intermittent — caves, dense jungle and longtail boats may have weak signal. An eSIM connects to local mobile networks, giving you typical mobile performance for maps, messaging and streaming in populated areas.
Mainland vs islands — what to expect
- Mainland (towns & airport): Good coverage and consistent speeds for navigation and streaming.
- Popular islands (Koh Phi Phi, Railay beaches nearby): Usually good in main piers and tourist hubs; signal weakens away from populated beaches and on open water.
- Remote spots & caves: Spotty or no service — download offline maps and save directions before heading out.

How eSIM for Krabi works — buy, install, activate
Buying and using an eSIM is faster than swapping physical SIMs. The eSIM is a digital profile added to your phone. Follow the steps below.
Step-by-step install (iPhone)
- Buy your Thailand eSIM on the product page and open the confirmation email with the QR code.
- On iPhone: Settings > Cellular > Add Cellular Plan > scan the QR code.
- Name the plan (e.g., "Krabi data"), set your eSIM as your data line, and ensure data roaming is enabled if prompted.
- Turn mobile data on for the eSIM line and confirm you see the network signal.
Step-by-step install (Android — Samsung / Pixel)
- Open the confirmation email and scan the QR or use the manual activation code if provided.
- On Android: Settings > Network & internet > Mobile network > Add carrier > scan QR or add manually.
- Assign the eSIM for mobile data and enable roaming if required by your OS prompts.
- Restart the device if the eSIM doesn’t register immediately.
Troubleshooting common issues
- QR not scanning: use the manual activation option delivered in email.
- No signal after install: toggle airplane mode, restart phone, or confirm the eSIM is set as your active data line.
- Dual-SIM conflicts: ensure your physical SIM and eSIM are correctly assigned for voice/data to avoid accidental roaming charges.

eSIM vs roaming vs local SIM — pros and cons
eSIMs offer instant delivery and no physical swap, making them convenient at airports and ports. Roaming with your home carrier can be pricey. Local physical SIMs work well but require a local store and registration. Choose an eSIM for speed and ease, a local SIM for extended stays where you want a local number, or roaming if you need to keep your home plan active.
Arrival checklist & travel tips for staying connected in Krabi
- Install your eSIM before flying if possible so activation is instant on arrival.
- Download offline Google or Maps.me areas for Railay and islands.
- Carry a portable battery — navigation and photo uploads drain power quickly.
- If you plan to hotspot, confirm your purchased plan allows tethering.
