Popular Questions
How does an eSIM work and how is it different from a physical SIM card?
An eSIM (embedded SIM) is a digital SIM profile downloaded to your device (no plastic card required). It lets you store multiple carrier profiles on the same device and switch profiles remotely in your phone settings.
A physical SIM is a removable card you must insert/swap manually; an eSIM achieves the same “network identity” function but via software provisioning instead of a card.
Is my phone compatible with eSIM?
Your phone must be:
1) eSIM-capable (has eSIM support in hardware/software), and
2) carrier-unlocked (not restricted to one mobile operator).
Quick checks:
– On iPhone: Settings → Cellular/Mobile Data → look for “Add eSIM”.
– On many Android phones: Settings → Network & Internet/SIM Manager → look for “Add eSIM” (wording varies by brand).
If you’re unsure, compare your model to an eSIM-supported device list (and confirm your device is unlocked).
How do I install and activate an eSIM on my device?
Before you start
– Use a stable internet connection (Wi-Fi recommended).
– Have your QR code (or manual install details if provided).
iPhone (typical flow)
1. Settings → Cellular/Mobile Data → Add eSIM
2. Choose Use QR Code and scan it
3. Finish prompts, then label the plan (e.g., “Travel eSIM”)
Android (typical flow)
1. Settings → Network & Internet / Connections → SIMs (or SIM Manager) → Add eSIM
2. Scan QR code (or choose manual install if needed)
3. After install, enable Data Roaming for the eSIM when you’re ready to use it abroad
When does the eSIM activate and when do billing/validity dates start?
For travel data plans, the bundle starts automatically when the eSIM first connects to a supported network with Data Roaming enabled (you can’t schedule a future start time).
Practical tip: you can install the eSIM before your trip, but to avoid starting early, don’t set it as the active data line until you arrive, and follow Apple-specific guidance to prevent accidental data usage during setup.
The eSIM profile validity is 365 days and the expiry timer starts when a bundle is assigned, then refreshes when a new bundle is applied.
Why doesn’t the QR code work, and what should I do?
Common fixes:
– Make sure the QR code image is clear (not distorted), increase screen brightness, improve lighting, and move the camera closer/further until it focuses.
– Confirm the eSIM isn’t already installed—errors like “This code is no longer valid” can happen if the eSIM was previously added or the scan failed.
– Ensure you have a stable internet connection during installation (Wi-Fi recommended).
If scanning still fails, use manual installation (enter SM-DP+ address / activation code if provided by your eSIM instructions) instead of QR.
Can I use an eSIM alongside a physical SIM at the same time?
Yes – on Dual SIM phones you can use one physical SIM + one eSIM (and on some models, two eSIMs) at the same time.
Typical setup is: keep your physical SIM for calls/SMS, and use the travel eSIM for mobile data.
What happens when the eSIM runs out of data?
– On fixed-data bundles, once you consume all data, data service stops (even if there are days remaining). Any unused data after the plan validity ends also expires and can’t be carried over.
– On some “Unlimited” bundles, after a certain amount of high-speed usage, you may be throttled rather than fully cut off (depends on the specific unlimited plan).
