# How to connect your eSIM after arrival

> Choose the right mobile-data SIM, check data roaming, and connect to a supported network.

Already installed your eSIM? When you arrive, check which line your phone uses for mobile data.

## 1. Check your plan

Make sure:

* your current country is included in the package's coverage;
* the package is valid or ready to start;
* you understand what starts its validity.

If the phone doesn't connect immediately, **don't reinstall the eSIM**.

## 2. Enable the installed eSIM

In your phone's SIM settings, turn on the eSIM that belongs to this order. The line's name on the device may differ from “2Chip”.

## 3. Select it for mobile data

> [tab] iPhone
>
> Go to **Settings → Cellular → Cellular Data** (or **Mobile Data**) and select the installed travel eSIM.

> [tab] Samsung
>
> Go to **Settings → Connections → SIM manager → Mobile data** and select the travel eSIM.

> [tab] Google Pixel
>
> Go to **Settings → Network & internet → SIMs** and select the travel eSIM for mobile data.

If your phone supports automatic mobile-data switching, check that it won't switch back to your home SIM unexpectedly.

## 4. Check data roaming

Some travel eSIMs need **Data Roaming** turned on because they connect through partner networks. Check the conditions of your package.

Enable it for the **travel eSIM**, if required. You don't need to enable roaming on your home SIM for 2Chip to work.

## 5. Let the phone choose a network

Leave network selection on **Automatic** first.

If it doesn't connect and 2Chip lists supported operators for your package, try one of those networks manually. Don't select an arbitrary operator.

## 6. Only change APN when required

Normally APN is configured automatically. If your package provides manual APN details, enter exactly those values in your phone's mobile network settings.

## 7. Test the connection

Turn off Wi-Fi and open a website:

* **Internet works:** you're connected.
* **No service:** check the eSIM line and supported networks.
* **Signal but no data:** check mobile-data selection, roaming and APN.
* **Very slow:** check coverage and package limits.
