Several times per year I am abroad for some conferences or holidays. And lack of Internet access from a cellphone there sucks.
In October I was in Munich, Germany for some internal Red Hat training. Had most of day for sightseeing but doing it without constant access to the Internet was a bit of disaster as I did not have time in previous week to mark interesting spots in Google Maps or to make any notes. And it was Sunday so all stores were closed == no way to buy local prepaid card.
In February I will visit Brussels, Belgium for [FOSDEM](http://fosdem.org/) and then Brno, Czech Republic for [devconf.cz](http://devconf.cz/). Local SIM cards for both countries would be nice.
Did not yet checked Belgium ones yet but did that for Czech Republic. And man… situation there is awful. 200MB for 150CZK from mobil.cz looks like best offer for prepaid. Disaster… I wonder how slow it will be as well.
But there are exceptions. In United Kingdom and Hong Kong I went to first Three shop and got unlimited data at affordable price. Spain was a bit strange as I had to register SIM card. But for 20€ I got something like 2GB of data.
In Poland I am topping up my SIM with 100 PLN every 2-3 months and this gives me 6GB of transfer as a bonus. I now have 45GB of data available without any extra costs. And prepaid cards from all operators are available to buy at every corner…
