II. Three coverage and speed in Europe

Mobile connectivity has transformed how we live and work, yet access remains uneven depending on location. We will explore coverage and speed data for three mobile networks operating in Europe.

1. Three coverage

In countries where Three operates, the network blankets nearly the entire main population centers with strong 4G/LTE signals. This includes major cities, smaller towns, main roads and highways, tourist sites, and airports.

  • Northern region: Coverage reaches 85%, spanning major cities like Stockholm and Copenhagen along with rural areas. Strong 4G and 5G networks keep you connected.
  • Southern region: Sun and connectivity go hand-in-hand in this region with 90% coverage! Enjoy seamless 4G and 5G in Rome, Barcelona, and coastal havens.
  • Western region: The UK boasts 75% coverage, focusing on bustling cities like London and Manchester. Reliable 3G and 4G networks power your digital life.
  • Eastern region: Austria joins the party with 80% coverage, ensuring major cities like Vienna and Graz stay connected. 3G and 4G options keep you informed and entertained.

Remember, specific coverage within each region can vary. Check Three’s coverage map for your exact location before jumping in!

2. Three speed

In addition to broad 4G networks, Three also offers swiftly increasing 5G coverage in many parts of Europe. Parts of the UK, Ireland, Italy, Austria, and Sweden now have 5G connectivity from Three.

  • Northern region: Generally considered to have the fastest Three speeds in Europe, with average download speeds exceeding 150 Mbps in major cities like Stockholm and Oslo. 5G availability in many areas further boosts download speeds, reaching up to 1 Gbps in some instances.
  • Southern region: Speeds are typically good, with average downloads exceeding 100 Mbps in major cities like Rome and Barcelona. 5G availability is increasing, but coverage is not as widespread as in the north.
  • Western region: Speeds can be variable depending on location, with average downloads ranging from 50 Mbps to 150 Mbps. 5G availability is limited, mainly concentrated in major cities like London and Paris.
  • Eastern region: Speeds are generally lower than in other regions, with average downloads ranging from 30 Mbps to 80 Mbps. 5G availability is rare, with 4G being the dominant technology.

Important points to remember:

  • These are just general estimates, and your individual experience may vary depending on your specific location and network usage.
  • It's always recommended to check online speed tests or contact Three directly to get a more accurate idea of speeds in your area.
  • Consider your internet usage needs when choosing a plan, as higher speeds come at a higher cost.

III. Three connectivity options for travelers to the EU

As a tourist visiting Europe, you have two main options for connecting on Three’s network – a local prepaid SIM card or a multi-country eSIM plan, or go roaming in 71 destinations: 

Option Description Pros Cons
Prepaid SIM Physical SIM card purchased in Europe or online before arrival. Affordable, flexible data plans. Easy setup. Wide network coverage Requires physical card (eject home SIM). May need top-up. Potentially higher cost than eSIM
eSIM Virtual SIM downloaded directly to your phone. Convenient, no need for physical card. Easy to switch plans. Often cheaper than roaming Not all phones compatible. Limited eSIM providers. Activation might require internet
Roaming Use your home SIM card's data and calls in Europe. Familiar and convenient. No SIM swap needed Extremely expensive data charges. Limited call/text allowances

Recommendation:

For most travelers, eSIM offers a good balance of convenience and affordability. However, if your phone doesn't support eSIM or your trip is very short, a prepaid SIM might be a good alternative. Roaming is generally the least cost-effective option unless your home plan has specific Europe-friendly offers.

IV. Three vs. Other European mobile operators

Some of Three’s major competitors in Europe include:

  • Orange: Strong brand presence, international reach, and diverse service portfolio. More expensive than Three.
