Frequently asked questions
Is an unlimited eSIM plan worth the extra cost?+
For trips over a week with heavy navigation, streaming, or hotspot use, yes. For shorter or lighter-use trips, a capped pay-as-you-go plan is usually cheaper overall.
Will an eSIM work on my phone?+
Most phones released in the last 4–5 years support eSIM, but it's worth confirming your specific model and that it isn't carrier-locked before purchasing.
