常见问题
Can OTP still be received after switching off data roaming on the home line?+
Yes, as long as voice/SMS roaming for that line is still switched on, since receiving incoming SMS does not rely on data roaming at all — the two are entirely separate mechanisms.
Does the home operator need telling in advance about travelling abroad?+
That depends on the individual operator; some may require roaming service activated in advance. Check directly with your own operator before every trip.
Does an eSIM bought here come with its own number for receiving SMS?+
That depends directly on the specific plan and its underlying network, and this detail varies between products. Check the detail page of the plan you are choosing, or ask the team if unsure.
If data roaming on the home line was left on for the whole trip by mistake, how would that be noticed?+
This page cannot state the cost or data volume that would result, since that depends entirely on the home operator's own terms. If unusual charges are suspected, check with your home operator directly rather than with this site's team, which only handles the eSIM plan purchased here.
What should be done if unsure the primary data line has been set correctly?+
Contact the team via LINE at https://lin.ee/skDPoNx (@esimonline) or email at esimonline.asia@gmail.com, mentioning the device model and operating system, so it can be checked before you actually depart.
