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.

Extremely useful, but theres one thing that is annoying.

This is a great app, it’s extremely useful for many reasons. It’s easy to navigate, allows me to keep up to date with my bills, lets me check new products easily, paying bills is easy and has generally made life easier in regards to keeping up to date on my O2 contract. It’s essential to anyone on O2.

However, there’s one thing that is annoying. Trying to contact someone is a bit frustrating at times, especially when you need to speak to an actual person over the phone. They force you to use a messaging service, and most of the time they’re busy which means you can’t even send a message. I know they probably implemented this system to cut costs, having a few people monitor a messaging service is probably a lot cheaper than hiring a 3rd party call centre. Still, it doesn’t beat actually speaking to someone, especially when you have a complicated issue regarding your billing and payment. Anyone on O2 should get this app, but their customer service can be frustrating.

I phone 11

I’ve been with o2 for years would never go anywhere else .I’m an I phone fan and this recent iPhone 11 I’ve got just ticks all the boxes for me,love the colour the size and all the features such has two cameras all the new apps and the face recognition for security definitely a plus point and it’s easy to navigate round,no complicated instructions to trail through trying to find out how to work it also the battery life is a lot longer it’s definitely worth getting if you can in my opinion. Certainly a huge step from my last phone an I phone 6s as much as I liked that one I’m really glad I decided to get the 11 well done apple you definitely got it right still working out what it’s capable off as I’ve only had it a week however I’m having fun learning 😬👍
