Why unlocking your phone from Three is a great idea:

  • Avoid expensive roaming charges - Data plans are notoriously expensive when travelling and adding roaming plans, especially in this data-hungry, Instagram era!
    Rather than adding a temporary package to your account, having an unlocked phone means that you can buy a prepaid SIM card or localized SIM card from a local shop at a better rate, allowing you to use your phone abroad just like at home.
  • Selling your Three for more money - If you come to sell your Three, an unlocked version will be worth a lot more money.
  • Switching Service Providers - Network providers often compete with one another, trying to one-up each other with new features, cheaper costs, and of course making contracts easier to get out of. For networks that still offer contracts, their phones are discounted and subsidised through the plan, which means they come locked.
    Using DirectUnlocks you can avoid expensive termination costs and unlock your phone for a relatively low price.

About Three

How to get the most out of your Three phone: unlock to save money and boost flexibility

In April 2003, the Human Genome Project was completed, later the same year, Concorde took its last flight and NASA launched its first manned space mission. Amidst this excitement, Three—a subsidiary of CK Hutchison Holdings—launched the UK’s first 3G-only mobile network (of course, today Three offers 3G, 4G and 5G). Three’s 2003 launch makes it the youngest of the UK’s incumbent mobile network providers. Initially, Three established an agreement with an existing 2G provider, followed by a deal with Orange. As its services expanded, Three continued to use existing infrastructure to provide coverage. In fact, as early as 2004, Three became the first network to maintain 80% population coverage, a regulatory requirement which took other providers several years to achieve.

Three entered the market ambitiously with immediate plans to sell handsets and open physical retail locations—by 2004, they began selling NEC and Sony Ericsson devices. At the same time, Three opened their first stores on Oxford Street and Kensington High Street, two prestigious London locations. As well as their own stores, Three sold devices and contracts through online retailers. Later, in 2006, they purchased almost 100 stores from O2. Three have been pioneering in their product and service launches, as well as in acquiring complimentary businesses. In 2015, Hutchison Whampoa acquired O2’s UK operations for more than £10 billion; however, the EU blocked the purchase on competition grounds.

Today, Three boasts more than 9 million UK customers, 300 stores, 4800 employees, and a strong, active network of data users who combined use more than 3 times the UK average. Continuing its record for strong network coverage, Three has the country’s most complete 5G holdings. Three’s rise to popularity coincided with a general surge in smartphone ownership as well as demand for the latest upgraded handsets, a major trend which led to major network providers selling locked contract devices en masse. These locked contract devices made ownership easier but limit consumer flexibility and reduce handset value.

Millions of UK customers use or own a Three smartphone, if you’re among these, you’ll want to consider a more device unlock.

Why should you unlock your Three smartphone?

  • Recently, major networks have announced that post-Brexit, roaming charges will return for most customers. The charges will be 10p a MB of data, 20p a text and 55p a minute for calls. Even networks like Three and Tesco who previously offered ‘home from home’ style agreements will be forced to reintroduce roaming charges. All users with locked will no choice but to pay these charges, reason being that no other SIM can be used with a locked device. However, even if a user remains ‘in contract’, a device unlock will help immediately avoid roaming charges. Unlocked devices work with any SIM, meaning when travelling to a foreign country, opposed to being subject to roaming charges, travellers can locate a local store and select any SIM-only deal offered by whatever domestic providers are available. Then, you can simply ‘plug and play’, insert the domestic SIM into your handset and continue using your phone without bloated roaming charges.
  • Locked devices are worth less than unlocked devices, unlocking your smartphone will boost the resale value. Hopefully this article has made clear how much more flexible and functional an unlocked device is compared to its locked counterpart. Well, it’s not just you whose noticed this, private buyers and recycling companies know it too. Most smartphone owners intend to sell their device eventually, whether they use the sale value toward a new device or spend it on something else. In this case, you’ll want to maximum that value to get the most out of your smartphone. Unlocking your device can boost the price by as much as 30%, a smart investment!
  • Locked devices are most often bought from major network provers, these ‘big players’ have higher monthly usage costs than their ‘challenger’ competitors. Of late, the usage market has exploded with new, lean start-ups focusing solely on usage. Without staffing costs, physical stores and inventory, these competitors can offer similar usage volumes at much lower prices. If you’ve bought or own a locked smartphone, unlocking it helps you access these deals and save you a ton of money each month. It’s likely you could save as much as £20 per month by switching to a new network.
