Most South Africa travel eSIMs receive their APN settings automatically. Manual entry is a targeted fix when the phone registers on a network but mobile data still does not load.
For a NoveSIM plan, the manual APN is data.esim. Do not substitute the APN of MTN, Vodacom, Telkom or another domestic operator, because the installed travel profile is not a local retail SIM from that operator.
NoveSIM South Africa eSIMs are data-only. APN settings control internet access; they do not add a South African number, conventional calls or carrier SMS.
Quick answer: First confirm that the South Africa eSIM is enabled, selected for mobile data and has Data Roaming on. Only then enter data.esim in the APN field if manual setup is required. Leave username and password blank unless NoveSIM Support provides different instructions.

When should you change the APN?
An APN change is relevant when the eSIM appears installed, the phone can detect or register on a supported network, but apps cannot use mobile data. It is not the first fix for every connection problem.
If the eSIM is switched off, the wrong line is selected or the phone has no network registration, changing the APN will not solve the underlying issue. Check those settings first.

Enter data.esim on iPhone
- Open Settings → Cellular or Mobile Data.
- Select the South Africa eSIM.
- Open Cellular Data Network when that menu is available.
- Enter data.esim in the Cellular Data APN field.
- Leave username and password blank.
- Return to Settings and restart mobile data.
Some iPhones do not expose the APN menu because the profile supplies it automatically. Do not install an unrelated configuration profile to force the field to appear.
Enter data.esim on Android
- Open the mobile-network settings for the South Africa eSIM.
- Select Access Point Names.
- Add a new APN rather than overwriting an unrelated profile.
- Enter a recognisable name and set APN to data.esim.
- Leave username and password blank.
- Save the APN and select it.
Samsung, Pixel and other Android phones use different menu labels. The South Africa Android eSIM guide explains the usual device paths.
Check the data line and roaming settings first
- The South Africa eSIM is turned on.
- It is selected as the preferred Mobile Data line.
- Data Roaming is enabled on the travel eSIM.
- Data Roaming remains off on the home SIM.
- Automatic mobile-data switching is disabled.
- Network Selection is Automatic.
For the complete arrival sequence, use the South Africa activation guide.
If data still does not work
- Confirm that data.esim was saved without spaces or spelling changes.
- Turn Airplane Mode on briefly, then off.
- Restart the phone once.
- Test a normal web page rather than only one app.
- Check that the plan is valid and has remaining usable data.
- Follow the South Africa eSIM troubleshooting guide.
Keep the installed eSIM. Do not delete it unless NoveSIM Support specifically instructs you to do so.

FAQ
What is the NoveSIM APN for South Africa?
If manual APN entry is required, use data.esim. Leave username and password blank unless NoveSIM Support instructs otherwise.
Should I use the MTN, Vodacom or Telkom APN?
No. A NoveSIM travel eSIM uses its own APN even when the plan connects through a South African partner network.
Why can I not see APN settings on iPhone?
The eSIM profile or carrier configuration may manage the APN automatically and hide manual editing. Check the data line and roaming settings before assuming the APN is wrong.
Should I delete the eSIM if data.esim does not work?
No. Keep the eSIM installed and complete the remaining troubleshooting steps. Delete it only when NoveSIM Support specifically requests it.
Final Recommendation
Use data.esim only when manual NoveSIM APN entry is required after the correct data line and roaming settings have been confirmed.
Leave unrelated APN fields at their defaults and do not copy settings from a domestic South African SIM.
If data remains unavailable, keep the eSIM installed and work through the full troubleshooting sequence before contacting support.
