Is mobile data more reliable than the Wi-Fi in my Lapland cabin or glass igloo?

Yes, often. While many remote hotels and glass igloos offer "free" Wi-Fi, it is often a slow, satellite-based connection shared by all guests, making it unusable for streaming or video calls (especially for uploading your Northern Lights photos!). A esimFlyer eSIM gives you a private, secure, and much faster 4G/5G connection that you don't have to share.
