常见问题
Does a phone with no SIM tray use a travel eSIM plan the same way as one with a tray?+
Yes, installation and use of the profile work the same way. The difference is that a tray-less phone has no fallback option of a physical SIM, so the home line and travel plan must live on the same device throughout.
If a second-hand tray-less phone turns out to be carrier-locked, what can be done?+
Contact the carrier that locked the device, or the seller, to ask about the unlocking process. Terms vary by carrier, and we cannot confirm on your behalf whether any given model can or cannot be unlocked.
How many profiles can a single device store?+
It depends on the device model and operating system version — there is no single figure that applies to every model. Check that specific device's own line settings directly to see the actual remaining capacity.
If the device is suddenly switched mid-trip, can the same plan still be used?+
The provider needs contacting to request a fresh profile for the new device, since the original profile was tied only to the old one. Contact the team via LINE at https://lin.ee/skDPoNx (@esimonline) or email at esimonline.asia@gmail.com, with your order number ready.
Does renaming a line in settings actually change how it functions?+
No. Renaming is simply a label to make the settings screen easier to read — it does not change the connection, data roaming, or expiry date of that line in any way.
If unsure how many profiles a particular device supports, who should be asked?+
Check that specific device's own line settings first, or use the site's device-compatibility checker for a preliminary read. If still unsure, contact the team via the LINE or email below, mentioning the device model.
