Europe (U.K.) prepaid triple(3-in-1) SIM card with 42 countries - SIM ONLY

Ordered two of these (one for me, one for my bf) for a recent trip from the US to the UK, topped up on their website (per instructions in response to the previous review) and activated before we left. Worked great the whole time and had surprisingly good coverage considering some of the very rural areas we were visiting, no we didn't have service everywhere but that's just not a realistic expectation. Were there for just under 3 weeks and the 10GBP All In One 10 top-up/add-on was plenty for one person, even using google maps HEAVILY for driving, walking, and public transport directions (ps if you are planning to use google for navigation in lieu of GPS in rural areas, download offline maps in advance). This method cost so much less than adding international service to my existing US plan, last time I did that it nearly tripled my bill for the month because data and minutes were OUTRAGEOUSLY overpriced. FYI - If you use Verizon or other CDMA carriers this may not work with your phone, bf's phone had this problem but luckily I had an old iPhone he could use.

This sim is ONLY usable if you have a UK credit card.
