Hi guys, i have run this in the iPhone forums we all like to save a few pennies, i recently reviewed my internet and landline phone costs. i was on BT for landline and Infinity 1 internet, thats not a boast, i got 40 meg per month. I changed to infinity 2 and now get unlimited 80meg download and 20 upload. I run a small business and check CCTv footage remotely, plus i play games and have 3 grandchildren who also play online games here. enough of my thrilling life lol! Recently BT released their Smart Talk App, // with apologies i removed the link - i did not realise against forums rules. simply Google BT Smart Talk or if you have a BT account you can see it in 'upgrading services' In short you can attach up to 5 smart phones to your landline and get your calls at landline rate using this app (available in other o/sflavours not just iPhone). So if you go BT with all calls anytime+ (breaking call every hour) you can natter endlessly on your mobile as though from your home phone, you get free 0800 and 0845 and half price landline rates to mobiles of any service provider. seems to me a very good deal, especially for those like me as well as any who have kids that overuse their mobiles, as long as you have WiFi or 3G (data costs only). thinking about while abroad or holidays, EE's bolt on's are very expensive for what you get - data roaming just don't go their, but using this app over any free WiFi i can scrounge in cafes etc it will be a boon. It will also work over G3, given it is only speech i'd guess little data would be used, so the bolt-on would i think offer much better value for phone calls at least. .
