US Mobile

US Mobile is a US-based MVNO primarily serving domestic customers but extending international reach through data-only eSIM plans for 130+ destinations including Mexico. A standout feature is 3GB of complimentary roaming data, which provides a safety net for unexpected connectivity needs or casual browsing during the first few days.

This option appeals to Americans traveling abroad who already use US Mobile domestically and want continuity with a familiar provider. The free roaming allowance adds practical value for short trips or situations where you're unsure how much data you'll need before committing to a paid plan.
