I have an HP ProBook 4530s that has an inbuilt sim card slot. I have been able to activate Cellular data usage meaning I can use my sim card data to access the internet. What I am unable to do is respond to text messages and do USSD requests. I have the Microsoft Messaging software; with it, I can only read received messages but i can not reply.
What can i do to enable text messaging and USSD dialing or is it not possible?
