I’ve recommended this O2 app to family an friends, ‘Why’ because it gives you all the information you need and require, at the end of your finger tips.

• Let’s you keep check of your data usage, so if your running low, use the app to add a bolt on, the good thing about adding a bolt on, what you don’t use rolls over to the following month, how cool is that.
• Also lets you keep an eye on your minutes, texts and your monthly billing.
• Shows you how much you have paid of your device, and what you owe, so when your due an upgrade, O2 will let you know.
• What l like the most, is the ‘Help Service’ which is built into the app, you have a problem with your devices, or billing, you can speak with an O2 Guru online or give them a call, their customer service is outstanding, they are always happy to help in any way they can.

l have both an iPhone and an iPad with a combined billing service. This is perfect for me, one less direct debit to think about.

O2 have combined everything together, in one small little package, they have really thought of everything. This app has made my busy life style a lot easier, so worrying and stressing about my monthly bill is now a thing of the past‘ l can’t rate it enough’. That’s why l have given a 5 Star rating.

From Yours Truly

Good company !!


I’ve been with O2 for nearly 15 years, they’ve always been helpful, polite and great value for money (if you’ve been with them long enough) coverage is generally really good.
My 2 gripes are that their recycling prices are poor, I recently exchanged my iPhone 7plus for an iPhone X, the recycled price they offered was easily £200+ less than what I could have received elsewhere (not just Ebay)
Secondly, there should be more competitive prices if you add a second phone or additional contract sim only deals if you decide to add them on O2 but their O2 priority offers and deals seems to offset any negatives so no real complaints, I’ll stay with them. I moved from Vodafone and I’ll never go back (loooong story)

Five Years On, Still No Support for Business Customers


I took out a contract with O2 Business over five years ago now and was surprised that only retail customers can make use of this app to keep track of their costs and data usage.

Five years later and this is still the case! Not only that, but the o2 Business account website is so utterly user-unfriendly as to effectively make it impossible to see how much data you are using or have remaining from your allowance until you get a text from o2 telling you that you have run out!

Businesses need to keep track of costs too o2! So perhaps instead of developing apps to tell me how my driving style is, you could (after five years) develop an app that is relevant to your core business.
