If you grab an imported Chinese phone bargain, will it work in the UK? or any other non-EU phone?

Over the course of the next five minutes (okay maybe 10) I’m going to explain the ins and outs of buying a phone from overseas. I’ll show you what you should be looking for to guarantee that a phone will work in the UK.

Don’t worry if you’ve already gone ahead and bought your first smartphone from overseas, it’ll still be useful to know the basics should you ever have to troubleshoot any connectivity issues. Those of you still to take the plunge are in luck as we’ll be covering ‘what to look for’ when importing your first Chinese or non-EU phone.

By the end of this article you’ll know:

1) How to tell if a Chinese Phone or non-EU phone will work in the UK on your network?

2) What bandwidths to look for that will support 2G, 3G & 4G LTE.

3) Which UK mobile network carriers are piggy-backing (using other networks).

4) Some random useful facts about mobile frequencies that might help you win a very geeky pub quiz.

How do I find out what frequencies my Chinese or non-EU phone supports?

When importing a phone you first need to check what frequencies does the phone support. You can do this by either looking on the phone manufacturers website or alternatively websites such as devicespecifications.com  are great for finding out full device information. Once you know what bandwidth the phone supports you can then cross check this against the carrier information above.

4G LTE is listed as either a bandwidth or as a number

In the UK, we currently use only three bands for our 4G network. These are Band 3, 7 and 20. Below I’ve converted the frequency to band number for all three frequencies. Often manufacturers decide to use either the frequency or the band, so hopefully this will come in handy.

Frequency 2600MHz = Band 7

Frequency 1800MHz = Band 3

Frequency 800MHz = Band 20

Didn’t you say something about piggybacking earlier?

That’s right, not all of the networks shown above use their own frequencies. It’s quite common for UK carriers to use a virtual network, or in simple terms, they rent the network spectrums from other providers. Until recently there have only been 4 networks in the UK that actually own the frequencies they operate on.

EE, Vodaphone, Three & O2. All the other carriers rent the frequencies or spectrums they use allowing them to provide network coverage for their customers.

*BT is the exception here as they recently bought some of the 4G spectrum and became number 5 in UK network giants club.

Here’s a very helpful list of all the UK Carriers who piggyback from over at USwitch.

Working out if my Chinese or import phone’s bandwidth is supported in the UK?

Below I’ve posted a couple of examples of phones and their bandwidths, so we can see what all this GSM / LTE Frequency stuff is all about.

LG Nexus 5


2G – GSM 850 / 900 / 1800 / 1900

3G – HSDPA 850 / 900 / 1700 / 1900 / 2100

4G – LTE band 1 (2100), 3 (1800), 5 (850), 7 (2600), 8 (900), 20 (800)


Supports all three UK 4G bands. Supports two of the UK 3G bands (900 + 2100). This means that the Nexus 5 phone should have no problems working in the UK.

The Cubot S200 (Chinese Phone)


2GGSM 850 / 900 / 1800 / 1900

3GHSDPA 850 / 2100

4G – The Cubot S200 does not have support for 4G LTE


The Cubot S200 doesn’t support 4G but will work on the 900 + 1800 + 2100 frequencies for 2G & 3G so it will work fine in the UK.

Here the boring bit I was talking about, read on if you dare! Or skip to the bottom and leave a comment if this helped you out.



What’s the difference between Dual Band, Tri-Band & Quad Band?

In essence, when a phone is classed as a multi-band device it can support multiple radio frequencies / bandwidths. A band is classed as a group of frequencies within a certain range. If your phone supports bandwidths 900MHz and  1800MHz, it is actually using two spectrums of bandwidth, 880-960MHz and 1710-1879MHz, one for upload and one the other for download. Each area in the world chooses what frequencies to output its cellular waves onto. If you’d like to delve a little deeper and brush up on you GMS frequency bands then check out Wikipedia GSM Frequency page.

Where will a Dual Band phone work?

Dual Band is one of the most widely used frequencies and uses 900MHz & 1800MHz. This will allow the phone to work in Europe, Middle East, Africa, Australia and most parts of Asia. If your mobile phone only supports this frequency it will not work in US and Canada.

The other Dual Band frequencies that are widely used are GSM 850MHz & 1900MHz. These frequencies are used in the US, Canada, Brazil and other parts of South America. If your mobile phone supports these frequencies is will not work in Europe, Middle East, Africa, Australia and most parts of Asia

Where will a Tri-Band phone work?

Tri Band or Triband like the name suggests means that the phone will work on 3 different frequencies. Generally, tri-band phones work the 900 MHz, 1800Mhz and the 1900Mhz spectrum which means you can use it in Europe, most of North America and most of Asia.

Where will a Quad Band phone work?

A quad-band phone will work almost anywhere in the world and covers the following frequencies:

  • 850 MHz (U.S. / Canada / Latin America / Brazil)
  • 900 MHz (Africa / Europe / Brazil / Africa / Australia / Asia (excluding Japan and South Korea))
  • 1800 MHz (Africa / Europe / Australia / Asia / Brazil)
  • 1900 MHz (U.S. / Canada / Latin America)

What is 1G, 2G, 3G, 4G, 5G?

1G – Stands for 1st Generation so without giving anything away this was the 1st wireless network that phones communicated on and was introduced in the 1980s to allow the transfer of analogue signals.

2G – You guessed it, stands for 2nd generation wireless network and was commercially launched in 1991. The advent of 2G allowed for digital voice to be transferred over radiowaves.

2.5G – They improved upon the 2G network allowing faster internet speeds more commonly known as GPRS.

2.75G – Or EDGE as you might see it appear on your phone is another enhancement on 2.5G.

3G – Was released to further the standards and improve speeds again.

4G – This is where things change, the 4th generation wireless network was created primarily for data use, allowing us to achieve even faster mobile internet speeds.

5G – Now we are looking into the future. As more people adopt data-heavy mobile plans and streaming increases we will inevitably have to open up more frequencies. This will be known as 5G and will enable faster speeds whilst supporting more people at once.
