CometSIM is a travel eSIM store offering prepaid mobile data plans for 190+ destinations worldwide — including single-country, regional, and global plans. Operated by Furvexo LLC (United States). All plans are data-only and delivered instantly as a QR code by email — no physical SIM, no roaming fees, no contracts. Travelers keep their home number for calls and texts while using CometSIM for data. Plans are priced in USD and start low, with a range of data sizes and validity periods. Coverage uses local partner networks with 4G/5G where available.
