To find out whether your Android smartphone can be equipped with eSIM compatibility:

Please download the eSIM.me APP from the Google Playstore under https://app.esim.me

At launch, the eSIM.me APP will check if your device is compatible or not and if compatible, which SIM card slots are supported.

If it is compatible, you can buy this eSIM.me Card.

In some cases, it may not yet be compatible but a Software update may provide compatibility, so check if an Android Software update is available for your device.

This issue only affects old eSIM.me v1 cards. Any eSIM.me v2 card purchased after the 01.03.2025 is not affected.

On Android 13+, disabling the SIM Slot that holds the eSIM.me Card, will render the currently active eSIM profile unavailable! 

If for any reason you must disable the SIM Slot that holds the eSIM.me Card,
first disable the active eSIM Profile in the eSIM.me APP and only then disable the SIM Slot.

From Android 11 and newer, Android assigns a CardID to every SIM card inserted in the phone and “remembers” what the setting of that SIM card was, including its status (Enabled/Disabled).

Android OS 13 can handle eSIM profiles. As eSIM Profiles are "digital" version of a SIM Card, they also get an CardID assigned.
So each eSIM profile gets its CardID, including its status.

When you (think to) disable a SIM Slot, what actually Android does is to set the status of that CardID to "disabled".

Unfortunately, Android is then unable to set the status back to "enabled" again. This is an Android BUG.

So it will remember it was disabled and you will not be able to access that CardID, eSIM Profile.

If you already disabled the SIM Slot while your desired eSIM Profile was enabled, you have the following options:

a) Reset your phone to factory settings, that will clear the “list” of the statuses of the CardIDs.

b) If your phone is rooted, you can follow this guideline a user created, to manually enable the SIM cards in the Android list:

Another option would be to install a new eSIM Profile, as the Android Bug does not affect the eSIM.me card itself, but only the single eSIM profile that was active the moment you disabled the SIM Slot.

This issue only affects old eSIM.me v1 cards. Any eSIM.me v2 card purchased after the 01.03.2025 is not affected.

Avoid disabling the SIM slot holding the eSIM.me Card in Samsung's One UI 6.1: 

Doing so, will disable all SIM Slots and a factory reset will be necessary to gain back access to the SIM Slots.
If you need to be able to switch off the SIM Slot with the eSIM.me Card, please stay with One UI 6.0 until further notice.

It is unsafe to purchase eSIM cards from any unauthorised provider, other than eSIM.me.

The eSIM.me Card, is the only eSIM card that is legally available.

Any 3rd party products, however they are called, are illegal copies of our intellectual property and buying these will bring the buyers into legal trouble!

We will do everything necessary to protect our property.

eSIM profile is property of the Mobile Operators.

Mobile operators will not tolerate their eSIM Profiles to be stored on plagiarism cards.

We will disclose to the mobile operators all eIDs of plagiarism cards and will enforce all eSIM profiles delivered to those cards to be invalidated.

We will also disclose those eIDs to the SM-DP+ Providers serving eSIM profiles, to black list those eIDs from receiving new eSIM profile downloads.

So users of plagiarism cards would loose all the eSIM profiles already downloaded on their plagiarism cards and would not be able to download new ones.

Fortunately, the eSIM ecosystem is a very small and organised system fully under the control and certification of the GSMA, the association of all mobile operators.

We think it is fair that you should be aware about the consequences of buying plagiarism cards!
