I am thinking about getting a sim card while in England for 2 weeks. I am not anticipating making many calls, but I probably will use 100-200 MB of data. Any suggestions for companies or brands, or are they all about the same? Is this worthwhile, or should I just upgrade my Verizon plan to international for a month? Thanks.
Carphone Warehouse do some good sim only deals:

driller,
If you're planning on using other SIM cards, your phone MUST be unlocked. You'll need to contact Verizon about that.
The super-cool thing about Verizon iPhone 5, 5S, 5C and 6/6+, is that they are unlocked out of the box! It's really an awesome deal to go to carphonewarehouse and get a SIM as others suggested. I did it, and it was only like $20 and it could even make a few calls.
Have fun!
Thanks for the info, I will pick one up when I get to Cardiff.
