Why can't I connect to the internet?

If you’re having trouble connecting to the internet, there could be a few reasons. Try the following troubleshooting steps based on common connectivity issues:

  1. Check Your eSIM Activation
    Make sure your eSIM is properly installed and active. If you’re not sure, go to your device’s network settings and ensure the eSIM shows as "active."

  2. Verify Data Settings and APN
    On Android and Windows, ensure the selected APN profile uses Name: globaldata and APN: globaldata. If needed, create this APN profile and then select it from the APN list.

  3. Confirm Data Plan Status
    Check that your data plan is active and not expired. If your plan has expired, contact BambooSIM support to purchase a top-up.

  4. Enable Data Roaming
    For iPhone, Android, and Windows, make sure Data Roaming is enabled for your BambooSIM eSIM. Keep roaming off on your primary SIM/eSIM to avoid unintended charges.

  5. Restart Your Device
    A simple restart can often resolve connectivity issues. Power off your device, wait a moment, and power it back on.

  6. Check Signal Strength
    Ensure you’re in an area with strong cellular reception. Buildings, basements, and rural areas may have weaker signal strength.

Important: The APN and Data Roaming steps above do not apply to Japan or Vietnam Single Use or Unlimited bundles.

If you’re still having issues after following these steps, please submit a ticket and we'd be happy to assist.
