3. SMS/MMS - Look for third-party apps that claim to transfer SMS/MMS from an Android device to an iOS. However, these apps/software has the risk of data being compromised and which may or may not safeguard your data.

   1. That may be possible with third-party software. Warning!; WhatsApp data through third-party software has the risk of data being compromised. Because the data will be churned through third-party servers, which may or may not be encrypted. Be judicious while selecting the software and taking this call.
