Hello, with Android the "natural" way is to store your contact info into gmail. This assumes that you actively use gmail as you main address obviously. If you do so, you will retrieve your contact info on any Android phone/tablet you own. If you want to give it a try you should export your contact from the application storing them on your PC as a csv or vcard file. Then import them in gmail on the PC.
Then you contacts will "magically" be synchronized on your phone. You might need to enable contact synchronization in the phone settings if you disabled it previously.
