The quick answer. Check the Yesim profile and selected data line, active plan, destination coverage and roaming setting. Use Yesim's personalized in-app troubleshooting before editing APN values; do not delete the profile as a routine fix.
Your questions, answered
Why does my Yesim eSIM show signal but have no internet?
Check that the correct profile is enabled and selected for mobile data, the plan is active with usable allowance, the current location is covered and the Yesim line's roaming setting matches its instructions. Use the selected eSIM's personalized troubleshooting. Yesim says profiles have predefined APN settings; do not substitute an unsourced universal APN or delete the profile as a routine fix.
Identify the problem before changing settings
A rejected promo code is a checkout issue. An installed eSIM that cannot browse is a connection issue. If you are still buying a plan, use the promo-code troubleshooting guide instead.
For connectivity, note whether the phone shows no service, a network signal without internet, or a working phone connection with a failing laptop hotspot. Those observations lead to different checks; an error label by itself does not establish a merchant-wide outage.
Work through the connection checklist
Yesim’s official troubleshooting instructions cover the installed profile, mobile-data selection, roaming and network registration. Use them alongside the instructions for your exact device.
| Check | What to establish |
|---|---|
| Profile | The correct Yesim eSIM is installed and enabled |
| Data line | The phone is using Yesim for mobile data |
| Plan | The package is active and has usable allowance and validity |
| Location | Your current destination is covered by that package |
| Roaming | The required setting is enabled for the Yesim line |
| Registration | Follow the official network-selection and restart guidance |
Keep your home SIM’s settings separate. A setting on one line is not evidence of the other line’s billing rules. If validity has not begun as expected, consult the installation and activation guide.
Do you need a custom Yesim APN?
Yesim’s APN article says its profiles have predefined settings and points to the selected eSIM’s “Internet not working?” guidance. Do not paste an APN copied from an unrelated profile or another travel provider.
The official troubleshooting page also warns against removing the profile or scanning its QR code again as a routine fix. Follow support’s instructions for your specific purchase if the basic checks fail.
Send support a useful record
Our suggested record includes the destination, device model, plan status, exact error, selected data line and steps already attempted. Send account identifiers only through the merchant’s official support channel and redact payment details from screenshots.
If the phone can browse but the laptop cannot, continue with hotspot troubleshooting. If you need a different package, return to the Yesim plan checklist.
