Reported user complaints
Reviewers report SIM malfunctions lasting over a month in some cases, unused pay-as-you-go credit expiring after 3 months of inactivity without prominent upfront warning, and unpredictable service interruptions. Confirm the exact recharge and credit-expiry terms before relying on this for a long trip. These are aggregated patterns from public reviews (Trustpilot, app stores, Reddit) as of 2026-07-15 -- not independently verified by Nomad Utilities and not necessarily representative of every reader's experience. Read current reviews directly before deciding.
