A little prep. A smoother trip.

Check your phone and the plan’s rules before you buy.

Your pre-purchase eSIM checklist

First, check that your phone can use an eSIM and is not locked to one mobile company. Check how many days the plan lasts and when those days start counting. For daily plans, find out when you get a new day’s data. If you need to share your phone’s internet with a laptop or another phone, check whether the plan allows it. Read the seller’s refund rules before installing the eSIM.

How many days should I buy?

Choose the number of days you need internet. If a seller has no exact match, we show its next longer available package and label the difference. A price per day is the package total divided by its days. Check the full package price before paying.

Can your phone use this eSIM?

Check the exact phone model in your settings, then check the manufacturer’s instructions for that model and region. The phone must also let you use another mobile company’s service. This restriction is often called a SIM lock. A phone that supports eSIM does not necessarily support every seller’s plan.

When do the days start counting?

Some plans start when you install the eSIM. Others start when it first connects to a local mobile network. For a seven-day plan that starts on installation, installing it before your trip can use up part of those seven days. Check the selected plan’s start rule and any deadline before installing it.

What happens when you use the data?

1GB each day for seven days is different from 7GB to share across the whole week. After the fast data runs out, a plan may slow down, stop, or require an extra payment. Check which rule applies. For daily plans, also check when the next day’s fast data becomes available and which time zone the seller uses.

Can you share internet with a laptop?

A hotspot, or tethering, lets another device use your phone’s internet. Check whether the plan allows this and whether shared data has its own limit. Your phone having a hotspot button does not mean every eSIM plan permits internet sharing.

Can you sign up and pay from your country?

A seller may ask you to create an account, use a local phone number, or complete an identity check. Check whether your phone number and payment card are accepted. Also check the currency and any fees at checkout. A price converted into your preferred currency is an estimate, so confirm the final charge with the seller.

What should you check before installing?

Read the seller’s refund rules before you pay. The rules can differ before installation, after the plan starts, and after data has been used. Keep the selected plan details and order confirmation. If you cannot connect, check how to contact support before deleting the eSIM from your phone.

A few things worth knowing.

What is an eSIM?

An eSIM lets you add a mobile plan to a phone without putting in a physical SIM card. For a travel data plan, you install the eSIM and use it to get online at your destination. Your phone and the seller’s plan must both support this, so check your exact phone model before buying.

Is 1GB per day the same as 7GB for 7 days?

No. With 1GB per day, you get a new 1GB amount each day at the time set by the seller. With 7GB for the whole trip, you can spread that 7GB across all seven days. You could use more on one day and less on another. We compare these two types separately.

What does “unlimited after 1GB” mean?

You can use the first 1GB each day at full speed. Once you use it all, the internet gets slower, but you can still keep using it. Full speed returns when your next day’s data becomes available. Check with the seller for that time and for how slow the connection becomes. “Unlimited” does not mean full speed all the time.

What does a speed like 384kbps mean?

It is a limit on how fast data can reach your phone. If the plan slows to 384kbps after you use the full-speed data, web pages and photos may take longer to open, and videos may stop to load. It is a speed limit, not a promise that you will always get that speed.

What is a hotspot, and why would I need it?

A hotspot lets you share your phone’s internet with a laptop, another phone, or another device. This is also called tethering. Some eSIM plans allow it and others do not. If you want to share your connection, check the seller’s rules before buying.

Are all sellers offering the same eSIM?

Not necessarily. We group plans with matching data amounts and days of use. They can still use different local mobile networks, have different rules for sharing internet, or start counting the days at different times. Check the details for each seller before you choose.

How current are the prices?

We check prices on a schedule and show when each seller’s price was last checked. Plans that people view or click are checked more often. While a new check is in progress, you can see the last price we found. A price may still change before you buy, so confirm it on the seller’s website. Prices marked “Sample” are examples, not live offers.

Does changing currency change what I will pay?

It changes how we show the price, not the seller’s price. The amount shown in another currency is an estimate to help you compare. The seller may charge in a different currency. Taxes, coupon rules and your bank’s exchange fees may also change the final amount.

Not every phone can use every eSIM. Check the instructions for your exact phone model and the seller you choose.
