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.

Travel add on

I am unhappy with o2 and, after many years with them will be changing my provider at the end of this contract. I went into rugby o2 store on two occasions to enquire about charges for a forthcoming visit to America. I was told on both occasions that my particular contract, as it was more than 4gb would cover America and Canada. Therefore I would not have any charges to my bill. This however was not the case. I was charged £4.99 per day every time I turned off the airplane mode, even though I did not make or receive calls or send texts for 4 out of the 5 days charged. I do not understand why the system has changed where I could receive texts free but would only be charged 50p if I sent one and if I made a call it was so much per minute. I didn’t need data because most hotels and restaurants provide Wifi. My husband is with 3 mobile and was able to use every aspect of his phone the whole holiday free of charge.

Not really for use with mobile data

For an app that is about your mobile phone you would expect it to be primed for use on mobile data. The app is great when you can get it to load - however if your phone only says that you’ve got 3 bars of 3G then getting it to load is a real problem. Fine for those who live in areas of permanent 4bar 4G but for the rest of us who don’t trying to see your balance can take half an hour. Either the app is not primed for mobile data usage or 3G doesn’t actually mean 3G with O2 and don’t even bother trying if you have less than 3 bars of 3G - it just won’t work.
If I could actually get the app to work smoothly then I would give it at least 4 stars but unfortunately it is either that the displayed network strength (3 bars/3G) is a hoax or the app is just not designed for mobile network data use.
