It's strange to hear you guys that you are struggling with such things as getting a SMS number. Like in my country, I can go to a local store and buy them for 1 euro each, no need to provide any information.

Was thinking the same thing. There are at least a dozen apps that you can get an SMS with like the one I mentioned TextMe. There's Google Voice.
Temp-Mail also has SMS services now.

It is quite country specific. There are the most services available for the US and the UK and less so for other countries.
Especially if the country requires SIM card registration.
