Where Airalo is better
Airalo also offers plans lasting just a few days. For a short city break, you do not necessarily need 30 days. Compare the total price: shorter validity does not automatically mean better value per GB.
Multilingual support is available around the clock, including through WhatsApp. That can help if you have installation trouble outside Dutch office hours.
Where HolySim is better
On the date checked, the 5, 10, 20 and 50 GB fixed plans cost less than Airalo’s corresponding 30-day plans. At 5 GB the difference is one cent; that alone should not determine your choice.
You can email in Dutch about installation and buy extra data through My eSIM. We have not tested access to our website from within Turkey.
Which should you choose?
Choose Airalo if…
Choose Airalo if a shorter plan fits your city break better or you value 24/7 WhatsApp support. Airalo says purchases cannot be made from Turkey: buy and install your plan before travelling.
Choose HolySim if…
Choose HolySim if you want a fixed allowance for up to 30 days and appreciate support in Dutch. Buy enough data before departure; do not assume every eSIM shop will be accessible during your stay in Turkey.
