FAQ
Clear answers to what travelers ask most about eSIM.
An eSIM (embedded SIM) is a programmable chip permanently built into your device. It stores carrier profiles digitally and can switch between them remotely — no physical SIM card required.
Most flagship smartphones from 2018 onwards. iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and select Xiaomi and Motorola models. See our Devices page for a full list.
Yes, in most cases. Carrier-locked phones may only accept eSIM profiles from the locking carrier. Contact your carrier to request an unlock — usually free after your contract period.
Purchase a plan, receive a QR code by email, go to Settings → Mobile/Cellular → Add eSIM, scan the QR code. The profile downloads and installs automatically.
Yes, and we recommend it. Install the profile at home over Wi-Fi. It remains inactive until you switch it on when you arrive at your destination.
Yes. Most modern phones support dual SIM — your home carrier for calls and a travel eSIM for data, running simultaneously.
Many plans support hotspot, but not all. Always verify before purchasing, especially for laptop work.
Deprioritized data gets lower network priority during congestion. Budget plans often use deprioritized data, which can result in slower speeds during peak hours in busy areas.
Casual use: 3–5GB. Light remote work: 5–10GB. Heavy remote work with video calls: 15GB+ or an unlimited plan with priority data.
Factory reset typically deletes all eSIM profiles. Contact your provider before resetting — some allow re-download, others require a new purchase.
Depends on the provider. Some profiles expire from purchase date; others from activation. Check validity terms before buying.
In several ways, yes. eSIM profiles are cryptographically bound to your specific device, making SIM-swapping attacks significantly harder.
The GSMA (Global System for Mobile Communications Association) sets mobile industry standards, including SGP.22 — the technical specification for consumer eSIM.
Possible causes: exhausted high-speed allowance, network congestion (deprioritized plan), low coverage area, or needing to toggle airplane mode to reconnect.
Typically 30 seconds to 5 minutes after scanning the QR code. Contact your provider if not activated within an hour.
