While registering to the guest portal, the registration is getting successful. But the user is not getting the SMS. Because the mobile number send by ISE is +91750XXXXXXX and our SMS vendor accepts only the number that dosen't have + sign before the number.
SO does anybody knows how to remove this + sign from the number.
Wow - an SMS provider that doesn't understand international telephony standard E.164 (been around since the 1980's). I would make that apparent to them as an area of "improvement".
There is an option to write a small Java Code function before making the API call to the SMS provider. You could write some regex to strip out the leading symbols (if present).
