eSIM installed but no internet?
Signal bars but no internet is almost always one switch: Data Roaming, turned off for the eSIM line. Here is where it is on iPhone and Android, and what to check if that is not it.

Why roaming has to be on
A roaming eSIM connects to Jazz as a visiting line. Phones block data on roaming lines by default, so until you allow it the eSIM sits there with signal and no internet. It does not cost extra and it does not affect your normal SIM.
iPhone
- Settings → Mobile Data (Cellular in some regions).
- Tap the FirstSIM line.
- Turn Data Roaming on.
- Back on Mobile Data, set Mobile Data to the FirstSIM line and turn off Allow Mobile Data Switching.
Android (Samsung, Pixel, Xiaomi)
- Settings → Network & internet (Samsung: Connections) → SIMs (Samsung: SIM manager).
- Choose the FirstSIM line and make sure it is switched on.
- Turn Roaming on for that line.
- Set Mobile data to use the FirstSIM line.
Still nothing?
- Restart the phone once after changing the settings.
- Network mode: set it to 4G/LTE automatic rather than 5G only.
- Data left: check your eSIM page — a finished plan looks exactly like a broken one.
If it still will not connect, message support with a screenshot of the SIM settings screen — a real person will look at it with you.
