Best 4G Network Coverage Providers In The UK

Several providers offer 4G networks to users across the UK. Here’s an overview of all of them, demonstrating their pros and cons.

4G Network EE UK

Boasting the widest 4G coverage of all the providers, EE UK is the largest operator. Their signal even extends to the underground, keep this in mind if you are a heavy data user or plan on spending a lot of time on the tube and still need data roaming.

4G Network Vodafone UK

Vodafone is known around the world and has earned a reliable reputation. In the UK, it comes in at a close second to EE and has recently deployed 4G LTE carrier aggregation technology.

For those who aren’t tech experts, this means that it has helped improve speeds and reliability of connection across the UK. It’s also known as the best SIM Card for UK and Europe because you can get service in other European Countries.

4G Network O2 UK

O2 UK is known mainly for its SIM deals as they don’t offer home broadband. Their coverage is relatively decent in London and other major cities.

However, the connection gets noticeably weaker in smaller towns.

4G Network Three UK

Although one of the leading mobile internet operators in the UK, Three has the least coverage across the country.

However, it does feature some of the most affordable packages. So if you’re planning to stay in one of the large cities and want the cheapest pay-as-you-go SIM in the UK, then Three could be a great option.

The brand is reliable but not necessarily the most affordable.

Best Deal

O2 UK offers one of the best pay as you go UK bundles for up to £30, which includes 100GB of data. But unless you’re streaming YouTube videos instead of ticking off your London bucket list, this package may be overkill. With this in mind, I’d recommend the entry-level deal.

  • 20GB of data
  • Unlimited minutes
  • Unlimited texts

How To Top-Up

It’s rather easy to top up your O2 travel SIM, with different convenient options to choose from.

Once again, you may need a UK card (so make a British friend and repay them with a pint).

Three UK Prepaid SIM Card

Three UK offers four different Pay As You Go prepaid SIM packages . These 5G ready packages include unlimited texts and calls.

Three UK Best international sim card UK packages

Best Deal

Of the various options available, the most cost-effective package is the unlimited package for £35. However, the 8 GB package at £10 should give you enough data for a single trip as a tourist.

What really sells the package is the ‘Go Roam’ feature. This feature allows you to use your phone outside of the UK. This makes it one of the best SIM cards for travelling Europe and the UK.

The EE prepaid sim card UK has two packages within the same price bracket that can be customised to your needs.

For example, you can either receive less data but more minutes. Or you can receive more data and fewer minutes.

Best Deal

If you’re looking for reliable connectivity but are on a tighter budget, then you may find EE’s affordable packages to be limited. However, if you have a few extra pounds to spend, then you can have an easy, hassle-free experience.

Regardless, I’d still recommend the entry-level package.

  • £28
  • 200GB of data
  • Unlimited minutes
  • Unlimited texts

How To Top-Up

To top-up your EE prepaid contract, you can buy and redeem an e-voucher from a convenience store. You can also top up online, call or text 150 from your EE phone.

Best Deal

Vodafone has a very affordable entry-level package that costs very little, but you get what you pay for, and the chances are that it won’t be enough to keep you going.

With this in mind, the best Vodafone UK tourist SIM deal is as follows:

  • £10
  • 5GB Data
  • Unlimited calls
  • Unlimited texts

How To Top-Up

Vodafone sells top-up vouchers through their My Vodafone app, which can be activated when needed.

You can text 2345 with the words ‘TOPUP’ and the amount you want to top up with. Another option is to call 2345 free from your Vodafone Pay-as-You-Go phone. This could be tricky if you don’t have access to a UK credit card.

VOXI SIM Options

In their own words, VOXI SIM card packages offer you “endless possibilities”. They offer rolling 30-day SIM card deals with complete flexibility to cancel at any time. VOXI has two main contract types: Endless Social Media and Endless Data.

Voxi SIM Card Package for UK

Best Deal

Seeing as data includes access to social media, I’d recommend the VOXI Endless Data package. It is considerably pricier than the Endless Social Media plan but offers fantastic perks.

The plan also has EU roaming which you can access at no extra cost.

  • £35
  • Unlimited data – for everything
  • Unlimited minutes
  • Unlimited texts

How To Top-Up

VOXI works differently from other providers because it uses a prepaid contract method. You can opt out of this to use their pay-as-you-go, but this restricts data access. With this in mind, you’ll need to cancel your “contract” before the end of your 30-day rolling period (in case of an impromptu change of plans to Hang Kong or South America!)

Additional Providers

These are just a few of the recommended prepaid SIM providers in the UK. Here are a few others that you may have heard of:

  • Virgin Mobile SIM – on the EE network offering 4G services, but their packages are more long-term focused
  • Lycamobile SIM card – on the 02 networks offering 4G services at a slightly higher price
  • SMARTY SIM card – on the Three UK network offering 3G and 4G services at an affordable rate

Best E-SIM Cards for the UK

E-SIM Cards are becoming more popular among frequent travelers because they bypass the need to purchase. physical SIM Card. Most of the time it’s more reliable to have a physical card with a local carrier if you are spending a few weeks in the UK, but if you will only be there for a couple of days, an E-SIM is the most convenient option.

There are no local carriers in the UK that provide E-SIM Cards, but if you want the convenience of one, there are some third-party sites where you can purchase them and have access to Data throughout the UK

The best E-SIM providers are;

SimOptions – After you purchase an E-SIM Card with SimOptions, you will get a QR code sent to your email, from there, you simply scan the code and activate the SIM card through their website.

Airalo – Airalo is the leading E-SIM company in the world. They have an easy-to-use app, so once you purchase your SIM Card for the UK, you can install the card and activate it right on the app (no need to mess around in your phone settings!

Orange Holiday Europe – Orange Holiday is the most expensive E-SIm, but they offer 14-day packages that work all across Europe, so if you will be traveling to multiple countries, this will save you the hassle of needing multiple SIM cards!

No matter which option you choose, you can simply purchase the E-SIM on the website or the app and they will give you instructions for installation.

The only downside to using an E-SIM Card is that you will pay for the convenience. They are often 2x-3x more expensive than you can get at a local provider. But if you only have a few days in London, it’s worth it to pay a little more so you can spend more time exploring the city!

How Much Data Do You Need?

The answer to this question depends entirely on your data-using habits and how long you plan to spend in the UK.

If your idea of killing time on the tube is streaming YouTube videos, you may run out of data before uploading that amazing Instagram shot. Even worse, you could lose your way and get stuck in the rain without direction.

As a guideline, you can consider how much data you use in a week at home and estimate a little bit more than that amount.

The good news is that most UK SIM cards with prepaid data allow you to top up rather easily. This is usually done by heading over to a convenience store where you can purchase a voucher.

Alternatively, you can head on over to Mobiletopup.co.uk which allows you to top-up your account as needed.

Keep in mind that most restaurants, hotels, and public areas offer free WiFi. I’d recommend switching over to WiFi access whenever possible.

How Much Does A UK SIM Card Cost?

Once again, this will depend largely on your data requirements. If you use a lot of data then it’s best to invest in a slightly pricier package so that you can use your phone without concern.

If the purpose of your phone is to take photographs (and maybe upload them to social media) and navigate your way through the city, then you can opt for the budget package.

Generally, a SIM card and data package will cost approximately £10 for the entry-level option and go up to £35 for the pricier alternative.

What Do You Need To Get A SIM Card?

Getting a SIM card in London is as easy as pie. In most instances, you don’t need to show your passport or any other form of identification. All that you need are the funds to make the exchange.

The one part of the process that you should check in advance is whether or not your phone is compatible with a UK SIM card.

Pre-paid vs. Pay-as-you-go Contracts

While looking for a SIM Card in the UK, you can choose either a prepaid phone plan or a pay-as-you-go phone plan.

A prepaid phone plan doesn’t have. contract, but you pay on a monthly basis a set amount of Data, minutes, and texts.

A pay-as-you-go phone plan is very similar, and sometimes the phrases are used interchangeably, but pay-as-you-go minutes, texts, and data typically don’t expire, so if you won’t need a lot of data, this can be a better option for you!

Will a UK Prepaid SIM Card Work in My Phone?

UK mobiles use the Global System for Mobile Communications (GSM). GSM mobile phones are widely used across Europe and the rest of the world.

If you arrive from one of these destinations, then all that you need is a SIM card.

However, a few international phones won’t work in the UK without being unlocked.

Alternatives to a Prepaid SIM Card

If you travel frequently, then you may find that buying a new tourist SIM card in each country can become tiresome.

Portable WiFi Device

A great solution for travel junkies is a portable WiFi device for travelling . With a portable WiFi device, you have access to a 4G mobile hotspot wherever you are in the world.

This way, you can stay connected in various instances, such as travelling the Ocho Rios beaches of Jamaica one day and landing in London the next.

There are several benefits to purchasing a portable mobile device, namely:

  • Full access to internet on-the-go
  • The small and slight size makes it easy to move around
  • It can save you money in the long run
  • Removes the hassle of finding a network provider and SIM in each new country

International SIM Card

Also known as travel SIM cards, an international SIM card can also save you a fair amount of money in the long run.

You can enjoy the same benefits of a local SIM, such as free incoming calls and local data rates. Some UK international SIM cards allow you to make cheap international calls from inside the UK too.

You can buy these SIM cards in most countries from cell-store providers. 

Free-Roaming in Europe or the UK

One of the unexpected benefits of many internet providers is Europe’s ban on roaming costs. This means that you can use the data (and make calls) on your UK SIM card in at least 30 other countries across Europe.

This makes a European trip a lot more convenient when it comes to connectivity and communications.

As a guideline, SIM cards from outside the EU will be subject to roaming charges and it’s best to invest in a UK SIM card. However, you may still be able to benefit from a European SIM card.

Brexit and Free-Roaming in Europe

There are concerns that Brexit’s impact on roaming fees won’t be positive. While some networks might charge a bit more for roaming charges, there are a few networks that promise not to (for now).

In fact, some providers are reassuring customers about their consistent services. Certain providers have the following to say about their services in relation to Brexit:

“We currently have no plans to change our roaming services across Europe. We will be working closely with the UK government and other European mobile operators to try to maintain the current EU ‘Roam like at home arrangements once the UK leaves the EU.” – O2
