Automatic network selection is normally the correct setting for a South Africa eSIM. Manual selection is a troubleshooting step when the phone does not register automatically or remains attached to an unusable network.
The eSIM can connect only to networks authorised for the selected plan. A carrier appearing in the manual list does not mean that it will accept registration.
NoveSIM South Africa plans are data-only. Manual network selection changes the attempted partner network; it does not add a local number, calls or SMS.
Quick answer: Confirm the eSIM is enabled, selected for mobile data and has Data Roaming on. Try Automatic selection first. If registration still fails, disable Automatic temporarily, test only the supported networks shown for the plan and return to Automatic after the check.

Check these settings before selecting manually
- Confirm that the South Africa eSIM is turned on.
- Select it as the preferred Mobile Data line.
- Enable Data Roaming on the travel eSIM.
- Disable automatic data switching.
- Keep roaming off on the home SIM.
- If manual NoveSIM APN entry is required, use data.esim.
If the phone is not configured to use the travel line, changing the network will not solve the problem. See the South Africa APN guide when the phone registers but data does not load.
Select a network manually on iPhone
- Open Settings → Cellular or Mobile Data.
- Select the South Africa eSIM.
- Tap Network Selection.
- Turn off Automatic.
- Wait for the available network list to finish loading.
- Select a network included in the current plan’s supported access.
- Allow time for registration and test one normal web page.
If registration fails, try the next supported network rather than every carrier displayed. Return Automatic selection on after the test unless support asks you to keep a specific network.
Select a network manually on Android
Menu names vary by manufacturer. On many Pixel phones, open Settings → Network & internet → SIMs and choose the travel eSIM. On Samsung, open Settings → Connections → Mobile networks or the relevant SIM manager path.
- Open the South Africa eSIM’s network settings.
- Find Automatically select network or Network operators.
- Turn automatic selection off.
- Wait for the scan to complete.
- Select one supported partner network.
- Test registration and mobile data.
Use the South Africa Android guide when the manufacturer menus differ.
Which South African network should you choose?
The live NoveSIM product page currently lists MTN, Telkom and Vodacom access across available plans, but the exact selected product determines which networks are authorised. Check the plan details before choosing.
Do not select a network solely because it shows the strongest signal. It must also be included in the plan. Review the current South Africa eSIM page and the network guide.
When manual selection is useful
- Automatic registration remains stuck after arrival.
- The phone is attached to a supported network but data repeatedly fails.
- A border or long route caused the phone to retain an old network.
- NoveSIM Support asks for a specific network test.
Manual selection is not a way to unlock every network or guarantee 5G. It is a controlled diagnostic step.
If no supported network accepts registration
- Turn Automatic selection back on.
- Turn Airplane Mode on briefly, then off.
- Restart the phone once.
- Move to an open area when indoor signal is weak.
- Confirm plan validity and device compatibility.
- Follow the South Africa troubleshooting guide.
Keep the eSIM installed and record which networks were tested. Do not delete the profile unless NoveSIM Support instructs you to do so.

FAQ
Should I use automatic or manual network selection in South Africa?
Use Automatic first. Manual selection is appropriate when automatic registration fails or support asks you to test a specific authorised network.
Can I select any South African carrier shown on my phone?
No. The plan can register only on authorised partner networks. A visible carrier may reject the connection.
Why does manual network selection take a long time?
The phone must scan available networks. Allow the scan to finish and avoid repeated toggling while it is searching.
Should I delete the eSIM if no network connects?
No. Return to Automatic, complete the other checks and contact support with the tested network names. Delete the eSIM only when instructed.
Final Recommendation
Keep a South Africa eSIM on Automatic Network Selection for ordinary use and switch to manual selection only as a controlled troubleshooting step.
Test only partner networks authorised for the exact plan, then return to Automatic after the comparison.
If none registers, preserve the installed profile and record the results before continuing with the full troubleshooting sequence.
