eSIM
Profile will not install
Use a stable Wi-Fi network, keep the QR or install code, and confirm the phone is unlocked. Delete a failed incomplete profile only after you have the original details.
TROUBLESHOOTING
When data
does not come up.
Work through install, radio, and sharing issues in that order. Most failures are an unused line, a plan that has not started, or a hotspot that never received the package.
SIGNAL
Installed, but no data
Turn on the travel line, enable data roaming if the issuer requires it, and wait for a local network. Airplane mode toggled on and off can force a fresh attach.
HOTSPOT
Device has no plan
Confirm the plan was assigned to this device ID. Power-cycle the hotspot, check battery, and reconnect clients to the correct Wi-Fi name.
SHARING
Phone will not tether
Many travel eSIMs limit hotspots. If tethering is blocked, a portable Wi-Fi device is the practical fix, not another toggle in Settings.
APN
Manual APN needed
Some SIMs and routers need the issuer’s APN. Do not guess values from another brand. Use the details that came with the plan.
SPEED
Slow after a threshold
Fair-use policies can reduce speed after heavy use. Check remaining data and whether a top-up is available.
STILL STUCK
Send the error, not just “it does not work.”
Include device model, destination, screenshots of the error, and whether the plan has started. That is enough for a useful support pass.
