Best International SIM Card for Travel

A single international SIM that works everywhere sounds perfect, but the per-gigabyte cost is usually higher than local options.

• Global SIMs cost roughly $15 to $30 per gigabyte
• Cover 100 plus countries on roaming agreements
• Local SIMs in most countries cost under $5
• Best for multi-stop trips under two weeks

For a long stay in one country, buy a local SIM; for a fast multi-country sprint, a global SIM saves the hassle.
