Buy a New eSIM
You cannot purchase an eSIM from most international providers once you're in Turkey. Their websites and app stores simply won't load.
Don't Get Locked Out of Your eSIM in Turkey.
Turkey blocked 30+ eSIM providers in 2025. If you don't set up before you fly, you might not be able to buy, install, or manage your eSIM at all. Guac eSIM works when others don't. Activate in seconds, no SIM swap required.

Install before you fly. Turkey's telecom regulator (BTK) blocks access to most international eSIM provider websites and apps on Turkish networks. You must purchase and install your Guac eSIM before departure.
What's Blocked in Turkey?
Since July 2025, Turkey's telecom regulator BTK has blocked access to over 30 international eSIM provider websites and apps from within the country. If you land without an eSIM already installed, here's what you can't do.
Install or Activate
QR code scanning and eSIM profile downloads require access to your provider's servers. If your provider is blocked, activation fails.
Top Up or Extend
Ran out of data mid-trip? If your provider's website is blocked, you can't buy more. You're stuck until you find Wi-Fi or leave the country.
Contact Support
Live chat, support pages, and help documentation from blocked providers are inaccessible from Turkish networks.
Use a VPN to Fix It
Turkey has also been expanding VPN restrictions. Many popular VPN apps are blocked or unreliable, so it's not a dependable workaround.
Switch Providers on the Ground
Most alternative eSIM providers are also blocked. You can't just switch to a competitor's website while in Turkey.
No data. No maps. No ride-hailing. No posting your Cappadocia photos. And no way to fix it from inside Turkey.
With Guac eSIM installed before your flight, you're connected the moment you land.
How Does It Work?
Turkey didn't ban eSIM technology. They blocked access to provider platforms. That means an eSIM purchased and installed before arrival works normally. Here's the process.
Step 1
Buy and install at home
Purchase your Turkey eSIM from Guac before your trip. Scan the QR code, add the eSIM profile to your phone, and you're ready. This takes about 2 minutes.
Step 2
Activate when you land
When your plane touches down, your Guac eSIM connects to a local Turkish carrier. Your plan starts automatically. No website visit needed.
Step 3
Stay connected, no blocks
Browse, navigate, message, and post normally throughout your trip. Your eSIM is already installed, so Turkey's website blocks don't affect you.

Pro Tips for Visiting Turkey
Install 24 Hours Before Your Flight
Don't wait until the airport. Install your Guac eSIM the day before you travel. Confirm it appears in your phone's cellular settings and label it 'Guac' so it's easy to identify. If anything goes wrong, you still have time and internet access to contact support.
Keep Your Home SIM Active
Use your regular SIM for phone calls and SMS. Set Guac as your data-only line so all internet traffic goes through it. This way you keep your home number for calls while using Guac for data.
Download Offline Essentials
Even with reliable data, download offline maps of Istanbul, Cappadocia, and Antalya in Google Maps before you fly. Save your hotel confirmations, flight details, and emergency contacts offline too. Belt and suspenders.
Don't Rely on Hotel Wi-Fi
Hotel and cafe Wi-Fi in Turkey is also subject to the same ISP-level blocks. If you need to access a blocked eSIM provider's website for any reason, hotel Wi-Fi won't help. Your Guac mobile data is your most reliable connection.
