An Argentina eSIM that does not connect usually needs a plan, line or network-setting check rather than a new installation. Start with the exact symptom and change only one setting at a time.
“No Service” points towards registration or local coverage. Signal bars with no internet more often indicate the wrong data SIM, disabled roaming, an inactive allowance or an APN problem. Slow data is a third, separate issue.
NoveSIM Argentina travel eSIMs are data-only. They do not include an Argentine number, conventional calls or carrier SMS, although internet calling and messaging work over data.
Quick answer: Keep the eSIM installed. Confirm the plan is active, enable the Argentina profile, select it for mobile data, turn on Data Roaming for that line and leave network selection automatic. If signal appears but data still fails, verify APN data.esim.

Identify the symptom before changing settings
| What the phone shows | First area to check |
|---|---|
| No Service or Emergency Calls Only | Location, enabled line and network registration |
| Signal bars but no internet | Selected data SIM, plan status, roaming and APN |
| Data works but is slow | Signal quality, congestion, allowance and background use |
Move outdoors before editing the configuration. A basement, lift, thick-walled hotel or remote road can produce a local reception gap even when the profile is correctly configured.
Confirm that the Argentina plan is usable
Check that the eSIM appears in the phone’s SIM settings and is switched on. Verify that the purchased plan has started, remains within its validity period and has data available.
Review the exact order rather than assuming that every Argentina plan activates at installation. The current product and setup context is available in the Argentina eSIM guide.
Select the correct mobile-data line
Choose the Argentina eSIM under Mobile Data or Cellular Data. Disable automatic cellular-data switching so the handset cannot return silently to the home operator.
Turn on Data Roaming for the travel eSIM when required by the plan, but keep roaming disabled on the home SIM. These are independent controls: enabling roaming for the NoveSIM line does not authorise the home line to use data.
Restore network registration safely
- Set operator selection to Automatic.
- Wait several minutes in an open location.
- Turn aeroplane mode on for about 30 seconds.
- Turn it off and wait for registration again.
- Restart the phone once if no network appears.
Use manual selection only after automatic registration has failed. Test only a network permitted by the purchased plan, then return to automatic mode after diagnosis. The Argentina manual network-selection guide explains the procedure.
Check APN data.esim when signal has returned
Most phones receive the APN automatically. If the APN field is empty or the plan instructions require manual entry, use data.esim. Leave username and password empty unless NoveSIM support supplies different values.
Save and select the APN, then refresh mobile data. Do not copy an APN from an Argentine domestic operator. See the Argentina APN guide for the device fields.
What if data works but is very slow?
Test a simple webpage in an open location and stop background transfers. Cloud photo backup, app updates, video uploads and tethered laptops can use the high-speed allowance or compete with the task being tested.
Speed also changes with congestion, terrain, building materials and the local partner network. The Argentina slow-data guide separates these causes from a complete failure.
Do not delete the installed eSIM
Deleting the profile can make recovery harder and may prevent another download. It does not repair expired validity, weak coverage or an incorrect data-line selection.
If the ordered checks do not restore service, take screenshots of the eSIM status, selected data line, APN and error. Send support the phone model, current Argentine location, displayed operator and the last time data worked.

FAQ
Why does my Argentina eSIM show signal but no internet?
The phone may be using the wrong data line, the plan may be inactive, Data Roaming may be off or the APN may be missing. Check them in that order.
Which APN should a NoveSIM Argentina eSIM use?
Use data.esim when manual APN entry is required. Leave unrelated fields unchanged unless support instructs otherwise.
Should I choose an Argentine network manually?
Start with automatic selection. Use a supported network manually only as a controlled troubleshooting step.
Should I delete and reinstall the eSIM?
No. Keep the installed profile and contact NoveSIM support after completing the safe checks. Delete it only if support explicitly tells you to.
Final Recommendation
Diagnose the Argentina eSIM in order: location and symptom, plan status, enabled line, mobile-data selection, roaming, registration and APN.
Test after each change and leave automatic network selection as the normal setting.
If data still fails, retain the profile and send support clear screenshots together with the phone, location and displayed-network details.
