So what is the pattern for the email address of the orangeclick.ch phone?
I did not see it; of course I do not have an account myself so I was looking around the http page only.
OP knows in US one can send an email/SMS to a Verizon phone from any email account using this pattern:
AAANNNNNNN@vtext.com
T-Mobile US using:
AAANNNNNNN@tmomail.net
AAA = 3 digit US area code
NNNNNNN = 7 digit mobile phone #.
Other US carriers have similar setups.
