Both featured offers provide free mobile data through an eSIM, meaning you won't need to wait for a physical SIM card to arrive.

Some providers also allow you to install your eSIM before travelling, so you're ready to connect to a mobile network when you arrive at your destination.

Is Nomad Really Free?

Yes. Nomad advertises its new-user trial as completely free, with no payment card required.

You receive 1GB of mobile data for three days in an eligible destination.

Once your free allowance expires or is used up, you'll need to purchase additional data if you want to continue using the service.

There's no requirement to take out a monthly phone contract or purchase a paid plan just to claim the free trial.

What Is an eSIM and How Does It Work?

An eSIM is a digital SIM card that's built into compatible smartphones.

Instead of inserting a physical SIM card, you download a mobile network profile directly onto your phone.

This makes eSIMs particularly useful for travelling, because you can arrange mobile data before leaving the UK and activate it when you reach your destination.

For example, you could keep your existing UK SIM for your normal phone number while using a separate travel eSIM for mobile data abroad.

Most travel eSIMs are data-only, so they don't provide a new mobile phone number or traditional calls and texts. However, you can still use internet-based services such as WhatsApp, FaceTime and Messenger.

What's the Difference Between a SIM and an eSIM?

A traditional SIM card is a small physical card that you insert into your phone.

An eSIM works in a similar way, but everything is handled digitally.

Both options can provide mobile data, but eSIMs are particularly convenient for travellers because they can often be downloaded and installed within minutes.

Can You Get Free Mobile Data Without a Credit or Debit Card?

Yes! Some mobile providers allow you to claim free data without entering any payment details.

These offers are often available as promotional giveaways, free trials or welcome rewards designed to attract new customers.

Depending on the provider, you may be able to claim free data with:

• No credit card required
• No debit card required
• No monthly subscription
• No upfront payment
• No purchase necessary
• No long-term contract

However, requirements vary between providers, so always check the individual offer details.

Some services may still require you to create a free account, download an app or verify your email address.

Can You Get a Free SIM Card With Data Without a Contract?

Yes. Several providers offer prepaid SIM and eSIM services rather than traditional monthly mobile phone contracts.

This means you can receive a promotional data allowance without committing to a 12-month or 24-month agreement.

Once you've used your free data, you can simply stop using the service.

If you need more data, some providers let you purchase an additional prepaid package, but this is separate from the original free offer.

This makes free SIM and eSIM giveaways particularly useful if you only need mobile data occasionally.

Can You Use a Free eSIM in the UK?

It depends on the provider and the destinations covered by the specific offer.

Some travel eSIM providers support the United Kingdom, but their free trials may only be available in selected countries.

Before claiming a free eSIM, check whether the UK is included in the promotional coverage list.

These offers are particularly useful for travelling abroad, rather than necessarily replacing your everyday UK mobile plan.

If you're looking for free mobile data specifically to use at home, make sure you select an offer that explicitly includes UK coverage.

Which Phones Support Free eSIMs?

Many modern smartphones support eSIM technology, including compatible models from:

• Apple iPhone
• Samsung Galaxy
• Google Pixel
• Motorola
• Other Android manufacturers

However, eSIM support varies depending on the exact model, country of purchase and network restrictions.

Before claiming an offer, check that your device supports eSIM installation and is unlocked for use with another mobile network.

You'll usually need an internet connection to download and install your eSIM initially.

How to Check if Your Phone Supports eSIM

On iPhone:

Open Settings, select Mobile Service or Mobile Data and look for an option to add an eSIM.

On Android:

Open Settings, go to Connections or Network & Internet, and look for SIM Manager or an option to add an eSIM.

The exact menu names vary depending on your device.

If you're unsure, check your phone manufacturer's official compatibility information.

Can You Keep Your Normal Phone Number?

Yes. On compatible dual-SIM smartphones, you can usually keep your existing SIM active while using a travel eSIM for mobile data.

This means you can continue using your regular phone number and WhatsApp account.

You can normally choose which SIM handles mobile data in your phone settings.

Tip: When travelling abroad, consider disabling data roaming on your regular UK SIM to avoid unexpected charges. Make sure your travel eSIM is selected for mobile data instead.

How Much Can You Do With 1GB of Free Data?

Although 1GB might not sound like a huge amount, it can be surprisingly useful when travelling.

It's generally enough for activities such as:

• Sending hundreds of WhatsApp text messages.
• Checking Google Maps and navigation.
• Looking up restaurants and attractions.
• Checking emails and travel reservations.
• Browsing websites.
• Booking transport and checking flight information.

However, video streaming, large downloads and video calls can use your allowance much more quickly.

If you're travelling for several days, we'd recommend downloading offline maps and avoiding unnecessary background data usage to make your free allowance last longer.

Tips to Make Your Free Mobile Data Last Longer

Download maps before travelling. Google Maps allows you to download areas for offline navigation, helping reduce mobile data usage.

Use Wi-Fi for large downloads. Download apps, films, music and software updates before leaving home.

Disable automatic app updates. Background updates can quickly use up a small data allowance.

Turn on Low Data Mode. Many smartphones have settings designed to reduce background mobile data consumption.

Avoid unnecessary video streaming. Watching videos can use significantly more data than messaging or browsing websites.

Are Free SIM and eSIM Offers Safe and Legit?

Free mobile data giveaways can be legitimate promotional offers designed to attract new customers.

Many providers offer a small complimentary data allowance so users can test their service before deciding whether to purchase a larger package.

However, it's always worth checking the terms before installing an eSIM.

Make sure you're downloading the official app, check which countries are supported and understand when your data expires.

You should also check whether the offer is restricted to new users and whether any additional purchases are optional.

A genuine free data offer shouldn't require you to make an unexpected payment simply to unlock an advertised complimentary allowance.
