Transfer WhatsApp from Android to iPhone 2024 [Official Free Method]
In this tutorial, we will show you how to transfer WhatsApp data from Android to iPhone with AnyTrans and iCareFone. We should mention in advance that these tools are not free, but they both do their job.
To migrate your data, you will need one of these apps, a computer (PC or Mac), USB cables, and a Wi-Fi connection. Also, install WhatsApp on the new device (iPhone) and log in to your WhatsApp account before transferring your data.
Transferring WhatsApp messages and data between devices with similar operating systems is easy. Google Drive supports Android to Android migration, while iOS to iOS transfers work with iCloud. However, inter-OS WhatsApp data migration is a bit complicated. But it is not impossible.
