Ive had similar problems myself. I opted for the laborious buying the physical sim and doing everything one at a time method but your post made me wonder if there was a better way. After a little bit of poking around it seems that if you are up to it you could build a solution using an Arduino and multiple Arduino GSM Shield's.

GSM Shield


It appears that up to 8 of the GSM shields can be hooked up in parallel. This would be a fun project if i had the time.

I mean it is not really that much work but it would be much nicer to have one platform from where you could access multiple sims from multiple countries. Looking at how much some people charge for a single message (5 GBP), it looks like doing the manual work could make for a decent business if you have good hardware and a decent website setup. Especially if you offer services for countries where people have to register their ID to get a sim card working.
