I'm getting a failure when trying to send texts or reply to text messages. Any idea what the problem is? The senders name is appearing so number can't be incorrect in my address book. Is there a setting I'm missing? Number was only ported from Vodafone to O2 today, if that means anything? Phone calls are fine (except issue with Bluetooth) Any help or suggestions appreciated. I'm sure all the problems I'm having will soon be ironed out soon but for now it's a pain in the butt!
