Seems like Lycamobile is now offering better roaming packs with Lycamobile than on Toggle. At least in Germany and Spain they seem to offer bundles that can be used in own country as well as in 16 other countries where Lycamobile is active (incl. US and Australia). In Spain a pack with 400 minutes, 400 SMS and 2 GB data apparently usable in all 17 countries and valid 30 days is 40 or 20 euros. Toggle offers for about the same price (the higher one of the two) only 1 GB with no minutes and no texts. However from the description on their web page I was not able to understand, what exactly these bundles include.
While Toggle bundles only work in 13 Toggle countries (I assume the identity for that country has to be present on the SIM), Lycamobile offers 17 countries.

Lyca commented in a forum that their roaming offers 4G access in the US, UK, the Netherlands and Switzerland even though the SIM is not enabled for 4G in it's home country. I have not yet seen any user confirmation whether this is true.
