# How to choose an eSIM plan for your trip

> Compare countries, validity, data limits, and activation rules before buying a 2Chip eSIM.

Start with the countries you're visiting. Then check the number of days and the amount of data.

## Four things to check

| What | What matters |
| - | - |
| **Coverage** | Every country where you'll need mobile data is included |
| **Validity** | The plan lasts long enough, and you know when the countdown starts |
| **Data** | You understand the allowance and what happens when you reach a limit |
| **Conditions** | Available networks, speed restrictions, and whether top-up is supported |

## 1. Check the countries

For a trip to one country, look at plans that cover that country.

If you're visiting several countries, check the full country list for each regional or multi-country plan. A plan named “Europe” doesn't necessarily cover every country in Europe.

## 2. Check when validity starts

The plan's validity may begin:

* when the eSIM first connects to a supported mobile network;
* when the eSIM is installed;
* immediately after purchase.

**Don't assume you can install every eSIM well before your trip.** The correct time depends on the plan.

> Check the plan's activation rule before you buy.

## 3. Choose a data allowance

| Plan type | What to check |
| - | - |
| **Fixed data** | Total GB available over the plan's validity |
| **Daily data** | Daily high-speed limit, when it resets, and what happens after the limit |
| **Unlimited** | Any fair-use or high-speed restrictions and what happens after reaching them |

> [!WARNING]
>
> “Unlimited” doesn't always mean unlimited data at full speed. Read the conditions of the specific offer before paying.

> [accordion] How much data will I need?
>
> Maps, messages, and quick searches generally use less data. Video calls, streaming, large uploads, and hotspot use can consume much more.
>
> Your needs depend on how you use your phone, so no weekly GB estimate fits everyone.

## 4. Can I top up later?

Only some eSIMs support top-up. If yours does, you can buy another package for the same eSIM when the option is available. There's no automatic renewal.

If top-up isn't supported, you'll need to choose another package instead. Don't plan your trip around an add-on that isn't offered for your eSIM.

## Before you pay

> [!TIP]
>
> The destinations, validity, activation rule, data limits, and other conditions match your trip. Check the final price before confirming the purchase.
