PPCGeeks - Windows 6.5 – Can’t receive sms from Way2sms.

What I have done is - forwarded my gmail mails to www.way2sms.com and it would send me sms alerts for the mails I receive on gmail.
The sms’ come to me correctly on my Nokia smartphone or may be any Nokia phone. However on my HTC mobile, I do not receive these sms’.
However I can receive all other sms from another mobile on my HTC. I can receive some from the Network operator but not all. I guess it’s not accepting sms’ which do not come from another mobile no. or a short code no.

Does anyone know what this problem is about and how to fix it.

Thanks in advance
