Hi Nickl360, here is the process that worked for me
Turn your (non apple) phone/device to Airplane mode
Now turn 'on' your wifi and connect to any network (say wifi network A --this is to have internet access) on the (non apple) phone/device. Open the Move to IOS app
Get to the enter the code from you apple device ---> Enter the code shown on your apple device set up page
Now your (non apple) phone/device will disconnect from the wifi network A and connect to another wifi network (temporarily) formed by your apple device.
After about a few good minutes of "preparing for transfer" or "preparing" you will see the options of data that you can transfer to your apple device from your (non apple) phone/device.
Select the relevant things you would like to move and press 'next' / 'done' and leave the devices close to each other till the data transfer is complete.
