Just a brief report on my trials with three.co.uk (3) and their feel at home programme Somewhat sadly perhaps, I'm a) a complete internet addict b) work is providing internet services, so being online even when away is kinda necessary. In the bad old days, I'd turn off roaming and even mess with the passwords so the phone couldnt get online. Then I'd buy some awful pay as you go phone from walmart which did great for calls/texts but was always rubbish for data. As things moved on, I cared much less about calls and much more about data for emails, forums, web etc. So I started using a US sim card from red pocket mobile found by our very own Wendy. This was brilliant and provided tons of US data, more US calls/texts than could be used and even some UK calls/texts too. All for between $40-$60. This worked really really well but was of course a different number so I still had to keep my UK number in a phone just in case someone texted an important mesasge. A while before we went this time, three announced its feel at home programme. This allows you to use your UK allowance of texts/calls/data in the states and other countries. So, calling someone in the UK from your hotel in the US just comes out of your allowance as usual. No incoming cost for them to call you. Same with texts. Data is the same, switch on data roaming and it'll come out of your UK allowance up to a fair usage policy of 25GB (which is enough for months of holiday). I can happily confirm that it worked brilliantly. Soon as we got to the states, DW and my phones both picked up at&t and worked great. Emails downloaded etc all fine. We could even call/text each other just as we would at home with no cost. It's really a great option since you don't need to faff about changing phones/sims/numbers, everything just works. The only wrinkles you need to be aware of are:- 1. you have to have had your account for 30 days if it's a contract/sim only. I believe pay as you go will work immediately since you have to top it up there's no credit there. 2. we found we had to call a few times to make sure they had actually turned on roaming 3. calling US phone numbers would still be the usual UK->US expensive calls (although they are discounted with the programme) Really impressive tbh and I wish all the cell companies would do the same. Three used to be the worst company. HUGE old phones, terrible coverage, but now they're up there as good as any of the others in my experience and this feel at home programme really makes a huge difference. I'm on a tariff offering unlimited everything including unlimited data for less than I was paying for a few GB on EE.
