Need iphone on rent

Hi, guys. Need some help. I just switched from an iPhone to an Android phone and want to move my WhatsApp chats from iCloud to Android. The only way to do this requires an iPhone, and I sold my old one before realizing this. I desperately need my data. If anyone has a spare iPhone or knows someone who would rent one out for two or three days, it would be a huge help. I just need to restore my iCloud backup. Thanks!
