My dolphin sim card when it is fixed in my dongle and when it is inserted into laptop, then internet is not working in d link dongle for the last 20 days. I have several calls on phone numbers 1503 and 1518 but none is attending to my calls. Kindly rectify the problem so that i am able to use internet with my d link dongle.
