Troubleshoot a Singapore eSIM
Check the line, activation rule, data selection, roaming requirement and network status before deleting the eSIM.
Keep credentials private
Do not post the activation QR code or full manual activation details. Share only the diagnostic information requested through the official support channel.
Troubleshoot in a safe order
First confirm the plan is active, within its validity and covers the current country. Then verify that the eSIM is turned on, selected for cellular data and permitted to use data roaming when required. Toggle airplane mode, wait for registration and test automatic network selection before changing advanced settings.
Use only the APN supplied for the exact plan. Record error messages and screenshots without exposing the QR code, activation code or payment details.
Do not delete the profile as a first step
Before leaving for Singapore, check that the phone is unlocked and eSIM-compatible. Match the plan's Singapore coverage, data, validity and hotspot terms to the trip, and save your accommodation address and first MRT route offline.
Many travel eSIM profiles are intended for one installation. Contact support with the order reference, device model, location and steps already tried before deleting it. Keep an offline route while connectivity is being restored.

Frequently asked questions
Why does the phone show signal but no data?
The wrong data line, roaming setting, APN, activation timing or temporary network conditions can cause this. Follow the plan-specific instructions before changing advanced settings.
