I worked out that buying the 4s outright will be more expensive than contract over 24 months with 100mins/100 texts, based on iPhone 4.
Think I'll wait for a contract deal.
I strongly recommend a Three 12 month sim-only contract £15 pm 600mins/2000txts/1GB for a good sim-only deal.
How good is three coverage these days? I know it had pretty awful feedback a few years back but this £10 tariff is tempting me!
SIM 300 - 12 month gives you:
300 Minutes
3000 texts
1GB internet
Winrya I've never had a problem. On occasions when I've not had signal, friends/colleagues on other networks havent either. Often I find I have 3G signal when others dont (particularly folk on O2 and Voda). It's important to point out that Three only operate/provide a 3G network. This has its pro's and con's.
Pro's are that when you do have signal its 3G and therefore fast. It's as such, reliably fast. Just the other day a m8 was trying to get footy scores on his O2 iPhone 4 and the app was taking ages to refresh because he could only manage a 2G connection. I pulled out my iPhone 4 on Three and got the scores up straight away. Having a smartphone is pretty much useless in my honest opinion if its >50% of the time on 2G.
Cons are that battery life is rumoured to be worse because somebody on a 2G + 3G provider will find themselves sometimes in an area where only 2G is available. When the phone is using 2G the phone will consume less power. Dont forget to make just a standard phone call all you need is 2G. If you live in a built up area though you will probably be on 3G all the time anyways. Another con is that you can't save battery life by forcing the handset only to use 2G (iPhone's allow you to do this). Forcing onto 2G can be useful when you have for example only 20% juice left and need it to last as long as possible.
