Common Questions

Frequently Asked Questions

For Turkish Travelers Abroad

Will my Turkish phone number stay active for WhatsApp and banking?
Yes. Cellesim acts as a secondary data line. Your primary Turkish SIM (Turkcell, Vodafone, Türk Telekom) stays active for calls and SMS. Your WhatsApp and banking apps remain tied to your original +90 number automatically.
Can I still receive bank OTP SMS from Akbank and Garanti BBVA?
Yes! As long as you keep your physical Turkish SIM enabled in your cellular settings, you can receive incoming SMS verification codes for Akbank, İş Bankası, Garanti BBVA and Yapı Kredi while using Cellesim for high-speed data.
Is it cheaper than Turkcell or Vodafone roaming packs?
Absolutely. Outside Turkey, local operators charge 200 to 400 TL per day for international data roaming. Cellesim provides local rates starting from 110 TL total for a 7-day plan — saving you up to 90%.
Can I share my internet (Hotspot) with others?
Yes! Unlike some competitors like Holafly, Cellesim eSIMs support data tethering/hotspots, making it perfect for sharing data with family or using your laptop during your trip.
Does my Turkcell package work abroad?
Turkcell offers international roaming but charges 200 to 400 TL per day. For a 7-day trip, that adds 1,400 to 2,800 TL to your bill. Cellesim provides the same coverage from just 110 TL total with no daily fees.
How do I install the eSIM before my trip?
Choose your destination plan on cellesim.com, receive a QR code via email, scan it using your home Wi-Fi in Turkey, then enable it after landing. The entire setup takes about 2 minutes.
