The following link will be useful for those who use Huawei (supports most models). Once you download and install this software, you will be able to make and receive calls through your 3G simcard even while browsing the internet. However the calls will be charged as voice calls. The biggest advantage of this is for Prepaid users as they can check the main
balance of their account.
