Do not change every setting at once. Start with the symptom you actually see.
Do not delete the eSIM yet. Most troubleshooting works best while the installed profile stays on the phone.

​
The plan did not activate

First check the activation rule for this specific plan. It may start:
  • on first connection to a supported network;
  • when the eSIM is installed;
  • immediately after purchase.
If mobile data already works but the app status updates later, do not reinstall the eSIM just to refresh the status.

​
The phone shows “No Service”

Check in order:
  1. the eSIM line is enabled;
  2. your current country is in the plan coverage;
  3. toggle airplane mode for a few seconds;
  4. restart the phone if needed;
  5. leave network selection on automatic first.
If automatic registration fails and 2Chip shows supported networks for the plan, you can try only one of those supported networks manually.

​
There is a network but no internet

Check:
  1. Wi-Fi is off;
  2. 2Chip is selected for mobile data;
  3. data roaming is enabled if this plan requires it;
  4. the package still has data and validity;
  5. APN is entered manually only when 2Chip specifically provides an APN for this eSIM.
Do not guess APN values from unrelated internet guides.

​
Internet works but is very slow

Check:
  • signal strength;
  • whether the issue affects all apps;
  • whether connection changes in another location;
  • whether high-speed data has been used up;
  • whether a daily high-speed limit has triggered a speed reduction;
  • VPN or data-saving modes.
5G support does not mean the device will stay on 5G everywhere.

​
It worked before and then stopped

Check what may have changed:
  • remaining data;
  • plan validity;
  • daily allowance;
  • which SIM is selected for mobile data;
  • current network registration.

​
If you need support

Open support from the related eSIM whenever possible. 2Chip can attach known package, eSIM, usage, device, and app context automatically. You may still be asked for things the app cannot reliably read, such as your current country, phone settings, exact error text, or screenshots.

Describe the symptom and add screenshots if useful.
