I don't know if this has been inquired before, but why did Nokia remove this function on their new series 40 phones like the 6280 or 6233/4 which enables users to switch the short message centres (smc) right before sending SMS?

For instance, my older Vodafone contract offers two different SMC numbers. One for internal, and one for external SMS. Depending on the recipient's network, I switch the SMC right before I send it away by pressing "sending options > sending profiles" and then chose the appropriate SMC.
Unfortunately, this functionality has been removed from new Nokia series 40 phones. My older Nokia 6230 still supported this, and even the 6230i does, but all newer phones do not.

Does anyone have an explanation or workaround for this? Or is there going to be some sort of firmware upgrade?
