Purpose
Check whether your phone supports eSIM before you rely on it for travel or work so you can resolve issues in advance with PEXX if needed.
Key Points
Your phone must support eSIM and be carrier unlocked.
Most iPhones from XR (2018) onwards and many Android flagships from 2020 onwards support eSIM.
Phones purchased in Mainland China often do not support eSIM.
If your phone is not compatible, contact PEXX support to discuss options.
Requirements
To use a PEXX eSIM plan, your phone must meet both conditions:
eSIM hardware support — Your phone has a built-in eSIM chip.
Carrier unlocked — Your phone is not restricted to a single mobile provider.
How to check for eSIM support
iPhone
Go to Settings > General > About.
Look for a field labelled EID. If you see a 32-digit number, your phone supports eSIM.
While there, check Carrier Lock — it should say "No SIM restrictions."
Alternatively:
Go to Settings > Cellular (or Mobile Data).
If you see Add eSIM, your phone supports it.
Android (Samsung)
Go to Settings > Connections > SIM Manager.
If you see Add eSIM, your phone supports it.
Android (Google Pixel)
Go to Settings > Network & Internet > SIMs.
Tap + and look for "Download a SIM instead?"
Android (other brands)
Open the Phone app.
Dial *#06#.
Look for a 32-digit EID number. If it appears, your phone supports eSIM.

Is your phone carrier-locked?
A carrier-locked phone only works with the provider it was sold through. If your phone is locked, eSIM installation can fail.
How to check
iPhone: Settings > General > About > Carrier Lock — should say "No SIM restrictions."
Android: Try a SIM from another carrier. Messages like "SIM not supported" or "Network unlock code required" suggest a lock.
How to unlock
Contact the carrier your phone was purchased from. Policies vary (payment status, minimum time on network, etc.).
My phone is not compatible — what should I do?
