Easy, simple, smooth!
Good combination of cost, data allowance and usage time. In fact EE website says usage will last for 12 Months for the 12GB, which is more than you advertised.
Top-ups are rather poorer value than the original purchase (I couldn't find anything that lasted longer than 1 month). So I'd really need to buy a new card each year, which is a pain for a remote system.
You could include an amount of overseas phone credit in the bundle
Cheap, works well, fast deliver
Perhaps make it a bit more clear that low cost calling means using a voip service
No problems stall with the SIM card in Europe
Good and reliable product
Prompt response from knowledgeable staff
Good advise and quick delivery
Fast support, good product
Website could use some modem updates
very accessible website, good information, very good good and swift service
