Signal but no 4G or 5G

Bars on the status bar but no 4G or 5G, and nothing loads. It is usually one of three things, especially the first time you use the eSIM.

1. Data roaming is off for the Atli eSIM

• A travel eSIM needs data roaming ON. Turn it on for the Atli line

2. The network mode does not match

Sometimes the phone is looking for 5G where the local operator does not offer it. Dropping to 4G fixes it.

• iPhone: Settings › Cellular › SIMs › Atli › Voice & Data › pick 4G or LTE instead of 5G Auto
• Android: Settings › Connections › Mobile networks › Network mode › pick 4G/LTE instead of 5G Preferred

3. There is no data coverage where you are

This one comes down to the network.

• Rural areas can have no data coverage at all
• Crowded places get congested and drop data connections
• Operator faults happen and are usually temporary

Try another network if your location has one.
