ByteSIM

ByteSIM offers unlimited 5G data plans on India's Airtel and Jio networks with 79 single-country plan options. The six-month money-back guarantee lets you test the service risk-free and return it if coverage doesn't work for your route.

This is the option for heavy data users who want true unlimited access and Jio's fast 5G where available. The generous return window is rare in the eSIM market and gives you real insurance against unexpected coverage gaps.
