The TravelSIM shop registration works fine now, please try to registrate again, wait for the confirmation email and click on it to activate your account.
please let me know where your problems were.
In your memberarea you will see each incoming call, each outgoing call, and each sent sms. you also can top up airtime in realtime, not with many payment options at the moment, but they will be added after and after
btw - the standard triggering process is through USSD - but
SMS triggering works now as well in manual mode ( send message ?*146*00+cc+number+#?, to number ?9146?), very useful for instance in UAE now.
cheers
