O2 is one of the largest telecommunication services providers in the United Kingdom that every year attracts thousands of new clients. The history of the O2 company began nearly 40 years ago but under the current name, it became known only in 2002. The brand participated in a number of different deals that resulted in changes of its owner. The latest of them took place on 1 June 2021 when O2 and Virgin Media merged to create Virgin Media O2.


O2 mobile services

Actually, the range of services offered by O2 doesn’t differ from the majority of offerings provided by other leading operators in Europe. You can become a customer of O2 opting for a SIM-only deal, a service contract or a pay-as-you-go plan.

What makes it really special is its focus on various special deals and free gifts for its clients. 

O2 Priority is a reward scheme for O2 users. It is available via a mobile application and provides a practically endless row of discounts and prizes. Those O2 subscribers who use the app wisely have the possibility to save quite impressive amounts of money.

The coverage ensured by this carrier is excellent. Over 99% of the country’s population can use the signal for making calls and exchange mobile data. Just imagine, already in 2017, 98% of people in the UK could get access to the 4G connection. Moreover, the company is actively working on the expansion of its 5G network.

But let’s have a look at the advantages of using the services of this operator in comparison to disadvantages of this option.

Benefits of using O2 services

  • Excellent coverage
  • A wide row of tariff plans
  • Very flexible contracts
  • A lot of special deals

Disadvantages of being a user of O2 mobile services

  • Rather high tariff fees
  • Lack of unlimited data plans

And actually, these disadvantages are quite often highlighted by users of O2 services. For example, Steve Kinsey from the UK wrote: “O2 are particularly bad at keeping you updated on better plans. I had a Pay As you Go data and calls plan and have been able to switch to EE and get 12 times as much data for the same price and equivalent calls etc.

Mark Davison also left a quite disappointing comment specifying an inappropriate quality of customer support: “I need to speak to a human again at 02. Does anyone have a telephone number for a human in customer services. The most annoying mobile company I’ve dealt with.”

But it’s really worth listening to the customers that have an opposite opinion. For example, Don also shared his thoughts: “Recently I purchased a sim card from o2. This sim deal gave me 18GB of 4G data, unlimited texts and unlimited calls all for £20 a month. This was ideal for me as I am a student and needed all those texts and data. The customer service on the website was fantastic and the setup of my sim card was easy thanks to the online tutorials. Overall I would rate my experience with o2 as 5 star and would highly recommend you go to them for a sim deal, especially if you are a student on a budget.”

And a user called John has very positive impressions: “O2 aren't the cheapest but their prices are fair on iPhones which I recently took out with a new contract. I've been with EE for years but couldn't stomach their greedy antics on the iPhone X and even their 4G can be patchy in London. No problems with O2 so far who have been nothing but helpful 50gb of data, free calls, free texts beat that EE!”

The fact that there are such different reviews means only one thing. Though the company is already well-established, there is still some space for improvements that definitely shouldn’t be ignored.

However, if you are in general satisfied with the services provided by O2 but have some issues with its signal at home or in the office, we can offer you a couple of solutions. And you will have amazing signal without a necessity to choose another operator. If it sounds interesting, just keep reading this article.


How O2 signal booster can solve your problems with connection

For many people it may come as a surprise but it is really possible to deal with O2 signal issues without the involvement of an operator in this process. And no, it is not magic. It will be a fully scientific approach.

We offer you to consider a variant of installing a signal booster at the place where you have faced problems with O2 connection. Actually, the modern tech developments allow us to buy devices of this kind that will be appropriate for buildings of very different sizes.

To understand why a cell signal booster can help you, it is necessary to understand what it represents itself. 

This device usually has several elements of equal importance. The set includes:

  • 1 booster box (this element is responsible for amplifying the signal transmitted by your operator)
  • 1 outdoor antenna (it is able to catch even the weakest signal that is not seen by your mobile devices)
  • 1, 2 or 3 indoor antennas (the number depends on the configuration of a booster. But usually there is 1 antenna of this type. It sends the signal from the booster to all mobile devices within the coverage area of your repeater)
  • Cables and mountings

Probably you’ve already guessed how it all works. An outdoor antenna gets a signal, sends it to a booster box where it will be amplified and then an indoor antenna has to spread this signal.

Today there are a lot of models that are able to work with different frequency bands and, consequently, improve signals of different types. But we will consider this aspect a little bit later.


O2 mobile booster: how to install it

Though O2 signal amplifiers may have a quite different configuration, the principle of their installation will always stay the same. The main task for a new user of a booster will be to fix the antennas correctly in order to ensure their right functioning.

And outdoor antenna should be installed either on the roof, or somewhere near the window. In some cases it will be important to find the right direction of the antenna in order to allow it to catch the signal transmitted by the nearest cell tower of your operator. Some booster boxes have LCD screens where you will see the tips for installation.

An indoor antenna should be placed in a room where it will be able to send the signal to mobile devices. There are different antennas of this type. Some of them should be mounted on the ceiling, some others can be placed somewhere on the table, for example. As we’ve already mentioned, there are repeater models that have more than 1 indoor antenna.

Antennas should be connected to a booster box with coaxial cables that are, as a rule, included into the kit. 

When you are choosing a booster, please, be very careful and read attentively whether a seller offers a full kit or you need to buy any elements additionally to make your device fully functional. For example, at MyAmplifiers, we always offer only those sets that can be used without any additional accessories.

We also advise you not to ignore installation manuals that a manufacturer usually provides. The results of you booster functioning will seriously depend on the way you install your device.

And now, when you’ve read all the general information, let’s move on to the options that we offer you to consider if you want to improve your O2 GSM, 3G and/or 4G signals.

Brian from the United Kingdom has already bought this booster. He wrote: “It's not my first booster. The first one that I bought in an ordinary offline store located in my neighbourhood has been already thrown away as it didn’t work at all. It was quite a difficult decision to buy a new repeater after such experience, but I analyzed a lot of reviews and came to the conclusion that it would be rather sensible to try (moreover, MyAmplifiers.com offers a warranty). I have chosen this model as it meets all my requirements. As my children and I are subscribers of different mobile operators, it was crucial for me to have a repeater that will be able to amplify signals provided by different carriers. And the booster is able to do it. I placed my order on Saturday and already on Friday I installed it at my place.”

Kristofer R. from Estonia also posted a review on our website: “I am impressed! I didn’t think that just in a minute all my problems with mobile internet and called would be solved. But it happened! I just installed my NS-300-Smart (fully on my own) and I noticed positive changes: the signal indicator on the display of my smartphone increased. This booster really works!”
