# Does Airalo, Holafly or Saily Work in Turkey? BTK Website Block & Pre-Flight Setup

Status: **WORKAROUND_REQUIRED** | Last verified: 2026-11-12

> **Verdict:** Pre-installed travel eSIMs from Airalo, Saily, Holafly, and Nomad work normally on Turkcell and Türk Telekom once you land—ONLY if you download and install the eSIM profile before boarding your flight. Inside Turkey, the BTK regulator blocks access to eSIM provider websites and apps on hotel Wi-Fi and local networks.

## Official Claim vs. Verified Reality

- **Official claim:** eSIM marketplaces advertise instant Turkey 4G/5G data packs that cost a fraction of Istanbul Airport (IST) tourist SIM counters.
- **Verified on the ground:** Turkey's Information and Communication Technologies Authority (BTK) blocks the web domains and app API endpoints of major international eSIM providers (including Airalo, Holafly, Saily, Nomad, and Mobimatter) on Turkish ISPs. This does NOT block cellular roaming itself—an eSIM profile already installed on your phone connects to Turkcell or Türk Telekom within seconds of landing. However, if you land at Istanbul Airport without the eSIM installed, you cannot open the Airalo or Saily app on airport Wi-Fi to download your QR code unless you connect through a working VPN first.

## Before You Fly (Pre-Departure Checklist)

- Purchase and install your Turkey eSIM profile on your phone while still on home Wi-Fi—verify that the eSIM line appears in Settings > Cellular / Mobile Service before boarding.
- Install at least one VPN with stealth/obfuscated protocols (Proton VPN, NordVPN, or ExpressVPN) on your phone before flying so you can open your eSIM app to check data usage or buy a top-up while in Turkey.
- Screenshot or print your eSIM QR code and manual SM-DP+ activation details offline in case you need to reinstall.
- Download the BiTaksi and Uber apps and register your account via SMS while your home SIM is still active.

## Practical Limits & Failure Modes

- Physical tourist SIM packages at Istanbul Airport (IST) and Sabiha Gökçen (SAW) counters frequently cost €40–€55 ($45–$60 USD) for 20 GB—roughly 4× to 6× the price of a pre-installed roaming eSIM.
- Phones using a local Turkish SIM card for more than 120 cumulative days require a hefty government IMEI registration tax; short-term travelers on foreign roaming eSIMs are unaffected.
- Discord and Roblox are blocked nationwide on Turkish ISP connections; a VPN or a foreign-routed roaming eSIM is required to access them.

## Frequently Asked Questions

### What if I am already in Turkey and forgot to install my eSIM before flying?

Connect to hotel or airport Wi-Fi, turn on a VPN (such as Proton VPN, NordVPN, or ExpressVPN) set to a European server, and then open your eSIM provider's app or website to purchase and install the eSIM profile.

### Does a European regional eSIM cover Turkey?

Often yes—Airalo Eurolink, Saily Europe, and Maya Europe include Turkey alongside EU countries, making them ideal if your itinerary combines Greece or Italy with Istanbul.
