I bought the eSIM before realising the phone is locked — can I get a refund?+
Contact the team through LINE or email at esimonline.asia@gmail.com with your order number and an honest account of the situation. Refund terms depend on the profile's status at that point, such as whether it ever successfully connected at all.
Can a carrier-locked phone still install an eSIM profile?+
Usually yes, since installing only saves the profile file onto the phone rather than connecting to a network. The problem appears only when it tries to actually connect to the destination network.
How do I know which network my phone is locked to?+
Normally it is whichever network you bought the phone from, or the one that provided the monthly contract at purchase. If unsure, ask that operator directly, giving them the phone's IMEI.
Can the site's device checker tool tell me the lock status?+
It can only tell you whether the model supports eSIM at all. It cannot report carrier-lock status, since only your original operator holds that information.
After unlocking, do I need to install the eSIM profile again?+
If the original profile is still installed on the phone and has not expired or been deleted, you usually do not need to reinstall it — just try switching that line on again once the unlock is complete.
What should I do before buying an eSIM for a second-hand phone with an unclear history?+
Always check the lock status first, either by asking the operator associated with the IMEI or by trying a physical SIM from another network. Do not buy a plan first and check afterwards.
