Installing an eSIM and activating its data package are not necessarily the same event. A Mexico profile can be added at home while its validity begins only under the conditions stated in the plan instructions.
Quick answer: Install the eSIM on stable Wi-Fi before departure. In Mexico, switch on the eSIM, choose it for mobile data, enable data roaming for that line and turn off automatic data switching. Test with Wi-Fi disabled.

Confirm that the phone is eSIM-compatible and carrier-unlocked. Read when validity starts, keep the QR code on a second screen and record any manual installation details. Do not scan a QR code merely to experiment; many profiles are designed for one installation.
Install the Mexico profile
- Open Cellular, Mobile Service or SIM Manager.
- Choose Add eSIM or Add Mobile Plan.
- Scan the QR code or enter the supplied details.
- Label the line “Mexico Data.”
- Keep your usual number as the default voice line if required.
Choose a suitable plan from the Mexico eSIM page. NoveSIM plans are data-only; we do not provide a Mexican number, conventional calls or SMS.
Connect after landing
Enable the new line and select it for mobile data. Turn on data roaming for the travel eSIM, leave network selection on Automatic and disable mobile-data switching. Then turn off Wi-Fi and load a fresh webpage. A signal icon alone does not prove that data routing works.
If activation does not produce data
Toggle airplane mode, restart once and check that the package is valid. For a NoveSIM profile, use data.esim only when the APN must be entered manually. Do not delete the profile. Work through the Mexico eSIM troubleshooting steps while it remains installed.
FAQ
Should I install my Mexico eSIM before travelling?
Yes, installation on reliable Wi-Fi is safer, provided you follow the plan’s activation-timing instructions.
Why does it show no service before Mexico?
The plan may have no supported partner network outside its coverage area.
Must data roaming be enabled?
Yes for many travel eSIMs because they connect through partner networks.
Should I delete and rescan a failed eSIM?
No. Preserve the installed profile and contact support before attempting removal.
Final Recommendation
Install before departure, but activate according to the product’s rules. On arrival, verify the selected data line, roaming toggle and automatic network selection before changing advanced settings.
