For mobile Internet in Paris, one of the best options is using an eSIM. An eSIM is a digital SIM card that allows you to activate a data plan instantly without the hassle of swapping physical SIM cards. The Ubigi app offers affordable and flexible prepaid eSIM data plans with excellent network coverage throughout the city and in over 200 destinations. By using Ubigi, you can also avoid the risks associated with connecting to unsecured free Wi-Fi networks (knowing that 25% of travelers get hacked via public Wi-Fi). You will ensure a more secure and reliable internet connection. You can use it alongside your local SIM card, so you can stay connected in case of emergencies. We recommend using WhatsApp to avoid roaming fees. Ubigi is the perfect choice for travelers seeking a safe, stress-free, and memorable trip. Check out our eSIM data plans for France here.
