Troubleshooting Guide

The eSIM will usually only activate when it connects to a supported network operator. For example, you can scan the eSIM in Australia without activating it. However, please ensure that you do not turn on data roaming and please turn off the eSIM line until you reach your destination.

Our eSIM generally works with no issues, however if you encounter any issues with the eSIM, please check the following:

  1. You must be connected to Wi-Fi when scanning the eSIM
  2. Turn off any other SIM and any VPN (if applicable), your phone also must also not be on airplane mode
  3. Turn data roaming on (Android: select all network)
  4. Ensure mobile data is sourced from our SIM and wait at least 10 minutes for activation – refrain from changing any mobile settings 
  5. APN should be “ctm-mobile” (if it is not internet please wait or restart the phone, do not change manually)
  6. Network operator should be automatically selected but if it isn’t please select manually to network operators listed below
  7. Restart your phone (off / on) or turn airplane mode on / off
  8. If you experience drop outs please turn on / off the eSIM line and you may also want to try selecting a different operator manually where applicable (see the list below)
  9. Please check your mobile network settings to make sure the eSIM was installed (occasionally it may looked like the eSIM did not install successfully however it may already be installed on your phone)
  10. Please do not delete the eSIM, if you accidentally deleted the SIM it may take up to 24 hours for us to reset the eSIM.

eSIM QR code along with the instruction will be sent via email instantly (please check your junk/spam email). Please note if you purchase a physical SIM in the same order, the eSIM will need to be sent manually (i.e. NOT instant), we recommend buying the eSIM separately.

      Hello we regret that you are having issues with the eSIM. It seems like it is working in Japan and you are currently in Vietnam.

      Please kindly choose Vinaphone on your network settings to see if it is better. We also ask all customers to please contact us so we can assist to get you connected again.

    Great coverage, but a warning when reaching the data limit would be beneficial.
