I had an Iphone with a sim card. Then I bought a new sim card with a new number to put in my Iphone because I was out of the country. Now I've lost the Iphone with the new sim card. I bought an Android phone and inserted my previous card. How can I retrieve my contacts? They're not on Icloud and not on Google.
Would it work if I put my sim card in another Iphone? If not, what other ways are there?
