The best site I have seen for information on pay as you go tarrifs.Thank you.

Ken – thanks for these: great references as always. Now that there is mandatory free roaming across Europe, three had upped their number of countries to ~60, so it probably deserves an update.
Ken replied:
Hi J,
Great feedback indeed – many thanks for the heads up about this. I’m currently working on a full update of this article so will ensure everything is updated over the coming few days.
Thanks again for the support and taking the time to let me know!

Hi Ken,
My child is coming to London and will be going down to Sussex to do his studies there. I am looking for a good plan which allows for the following :-
1. HUGE DATA – AT LEAST 6 GB or more
2. INTERNATIONAL CALLING
3. UNLIMITED LOCAL CALLING
4. TEXTING – MAX 1,000
I am not sure of what to get, whether to get a 12 months plan or a PAYG plan?
I don’t need a mobile phone as I have my own device.
What would you recommend?
Thanks / RLV
Ken replied:
Hi Ramesh,
Many thanks for your comment. Before continuing, I recommend having a look at my guide for people visiting or moving to the UK. In short, one of the key things is your son won’t be able to pass a UK credit check immediately, so he should restrict his choice to Pay As You Go deals. As discussed in that article, giffgaff is probably the best option (no UK credit check, flexible goodybags, low-cost international calls, etc). You can pay £18/month for 2000 minutes, unlimited texts and 6GB of 4G internet.
Hope this helps,
Ken
Ramesh Vasnani replied:
Hi Ken,
Your reply very well appreciated.
A final question. Which is the best PAYG card which also allows for reasonable/cheap International calls & has good data as well?
I have seen THREE & GIFFGAFF SIMCARDS & the service seems to be good. Its it better to go for a 12 month contract or to go for monthly basis?
Thanks / Ramesh
Ken replied:
Hi Ramesh,
Because of the issue with credit checking, it unfortunately wouldn’t be possible to get a 12-month contract straight away. Therefore, the only option available at present will be 1-month rolling deals on a pre-paid basis (e.g. giffgaff or Three Pay As You Go). To be honest, I think both giffgaff and Three are good networks but I’d probably have a slight preference for giffgaff in your situation (due to the lower-cost international calls, the ability to top-up using non-UK cards, better UK coverage, and potentially a lower monthly price for the amount of data you require).
Hope this helps!
