I'm leaving for Europe in a couple days. I'm spending a few days in England and then a few days in Hungary before returning to the US. Unfortunately, I have not given much thought to my phone/internet options until now.

Anticipated needs: 

* 5-10 phone calls total, all in-country, with no more than 60 minutes total talk time;

* 30-50 text messages total, all in-country;

* light Web browsing, with a conservative (high) estimate of 75MB/day for data use.

I have a Verizon iPhone 5 and am willing to take it to use with a different SIM or, if I must, to use as-is with Verizon's "Global Services" rates. For reference, the latter are the same for both England and Hungary: $1.29/minute for voice, $0.50/$0.05 to send/receive texts, and $0.25/MB for data.

What is my best option? Best means both cheap/convenient, but weighted mainly toward cheap.

Happy to elaborate if more info needed.
