I have an unlocked Huawei E1550 and I am using a SIM whilst abroad. In Tools/Options/Text Message the SMS Message Center number is greyed out. It contains the number of the original Message Center and I cannot enter the one I need. What should I do?
First disconnect the software and if the same thing happens again, remove your sim and insert in to mobile phone and change your smsc. Hope it helps.
In order to fix the problem, remove the software from your computer (Control Panel > Uninstall a program) and run a registry cleaner from the database of Software Informer to make sure that there are no leftover registry keys or toolbars in your system. After that, download and install the updated version of the software from the official web page.
