We've got by for years on pay-as-you-go old Nokias, but we're interested in getting modern and upgrading to iPhone-type phones.
What is the cheapest way of getting a monthly contract (if that indeed is the best route), and what are the cheapest phones (not wanting games, apps, Facebook, Twitter, all that nonsense).
Why do we want to upgrade? Well, we're taken with the idea of the door-bell app which buzzes through to your iPhone so you can tell the caller that you can't get to the door (i.e. when you're in fact miles away).
You would have to have a Broadband internet connection. This comes with a box of tricks which gives you wi-fi. A smart phone, and the boor bell device, would use this to talk to each other. If you were abroad and someone rang the bell, you would either need your phone to be able,to connect to wi-fi where you were, or a 4g phone signal, which would then, possibly cost a lot of money depending on the deal with the company you went with when buying your phone (Vodafone, EE, O2 etc etc).
Much better to have new locks fitted.
I have an excellent deal with Virgin as they supply my home broadband but there are plenty of options. I like EE and Giffgaff.
The difference between Android and iPhone is mainly the operating system but both are relatively simple to get to grips with. iPhones are only made by Apple and are very expensive; many companies make android phones and you can pay anything from £50 upwards.
I recommend that you do not make a phone running the Windows operating system as it is unlikely to have the App you need for the bell.
You can easily do what you want with a £100 android phone and a cheap monthly sim card, it depends how many phone minutes you need. The £7.50 a month SIM only deal from Tesco looks good
I would be inclined to avoid iPhones . You cannot easily change a failed battery. Most Android Smart phones you can put a new battery in easily. The deal with Tesco looks good to me.
