The correct APN depends on the exact eSIM product you purchased. Check the product name in your confirmation email or in the BambooSIM portal before changing any settings.
| eSIM product | APN setting |
| ----------------------------------------------------------------------------------- | --------------------------------------------- |
| Legacy eSIM with globaldata in its installation instructions | Set both Name and APN to globaldata |
| Viettel, MobiFone, Japan KDDI, South Korea SKT Unlimited, or Australia Vodafone | Leave the APN on Automatic |
| All other travel eSIMs | Leave the APN on Automatic |
Do not change the APN to globaldata unless the installation instructions for your eSIM explicitly require it. Using globaldata on another product can stop mobile data from working.
Set globaldata for a legacy eSIM
If your device provides editable APN settings:
- Open your device's Mobile Network, Cellular, or Access Point Names settings.
- Add a new APN profile if needed.
- Set Name to
globaldata. - Set APN to
globaldata. - Leave the remaining fields unchanged, save the profile, and select it.
The value is case-sensitive and should not contain spaces.
Japan KDDI eSIMs normally configure themselves automatically. Only use the manual Japan Unlimited APN settings as a final troubleshooting step after the standard connection checks.
If you are unsure which product you have, please submit a ticket before changing the APN.
