Now I won't waste your time and directly goto the main moto.
For this purpose you would need one software named universal software
and IMEI number of your datacard.
This trick will work only for GSM Card and not for CDMA so before all
make sure that your dongle is not CDMA so we'd move further.
Here we go then download this rar file here and extract at some place.
Now if your datacard that is going to be universal datacard is still connected to machine then run the extracted file. You will see the below screen as follow that one I've done for my own datacard.
Sometime guys you'll face problem of not having IMEI number of your datacard may be some unreadable or totally missed. But don't worry we have solution for that. Your datacard's software suite provides facility to see that one. How it is going to do then? Many software suite provide option like diagnostics where you can find details of your dongle. And if it is not there then call customer care service of your datacard they will instruct you to sort it out.
Based on your device like whether it is ZET, huawei or anything select same option and place your IMEI number and press calculate button.
If you don't find your datacard's manufacturer here in this universal software still don't worry try to use by each of one tabs of this software but start by huawei because most of dongles are made by this company so chances are very great to success by this way.
Now if you followed through all this way then only one thing to say......i.e. hurray your datacard is now open for all simcard to insert in and now Enjoy freedom from single sim datacard.
