Sometimes, due to the carrier not responding promptly, an already installed eSIM will display 'Activating...'. This situation usually resolves itself automatically within 10-15 minutes. You can try disabling other SIM cards, leaving only the newly installed SIM card on your phone, which typically resolves the issue faster. You can also contact MicroEsim customer service.

P.S.

Sometimes, you may get the troubleshoot "eSIM Cannot Be Added - This code is no longer valid" Error as below. Mostly, the eSIM is already added to your phone and you may check the sim list. For detailed steps on how to resolve this issue, please refer to our guide on resolving the 'This code is no longer valid' Error.

2. Configure the eSIM Label

After activating your eSIM, you will typically see the SIMs List settings page. The newly added eSIM will appear at the bottom of the list and is often labeled "Travel" or other preset labels by default. If you prefer a different label, you can customize it at any time. Simply select the corresponding eSIM and modify its name according to your preference. Here we customize the label as "MicroEsim" in the blank "CUSTOM LABEL".

3. Configure Defalt Line and Cellular Data

Sometimes the default line settings will appear.

  • Default Line >> Select "Primary".
  • iMessage & FaceTime >> Select "Primary", which allows you to keep your original number for iMessage and FaceTime.
  • Mobile Data or Cellular Data >> If you haven't arrived in your destination yet, select your original SIM card. If you have already arrived in your travel destination, select the newly added eSIM. Be careful not to turn on the "Allow Mobile Data Switching".

Enable Roaming

Typically, the newly installed eSIM is turned on by default. If you do not plan to use it immediately, you can turn it off. Once you arrive at your destination and are ready to use the eSIM, ensure the following:

  • This travel eSIM line is set as the default line for Cellular Data.
  • Ensure that this eSIM line is turned on and Data Roaming is enabled.

*Note: Some eSIM products come with a local IP and do not require roaming. They can be activated immediately after installation but network access available only upon arrival at your destination. This information will be included on the eSIM data plan product page

Select Available Network / Carrier

Mobile devices usually detect and connect to the appropriate network automatically based on your eSIM settings and location. This process can take a minute or two. However, sometimes the automatic network selection may fail or connect to the wrong network. If you’re having trouble with your mobile data connection, first identify which networks your eSIM is meant to use in the country you are in. This information is typically found in the description of the MicroEsim product page.

Manually selecting a network will usually resolve connection issues caused by auto-selection glitches, and will also override auto-selection, so if you travel to a new country or region during your travels, you may need to manually switch again.

Follow these steps to manually select the correct network:

1) Go to Settings > Cellular.

2) Select the eSIM or Cellular Plan under the SIMs section.

3) Tap Network Selection.

4) Turn off Automatic.

5) Select the correct network from the list.
