What is Profile transfer?

No. The feature needs support from the source handset, the destination handset, and the provider that issued the profile. Many travel plans do not support it, because the profile is tied to the device it was first installed on. Check your plan's terms before switching, or send us the plan name and we will check.

The transfer features built into operating systems are generally designed to work within the same family, so moving between different systems usually means installing afresh instead. If you are changing platform, plan on the assumption that a new profile will be needed, and check in advance whether the provider will issue one.

Generally not on your own. A profile deleted from a device usually cannot be restored, and whether a replacement is issued is the provider's decision: some will under conditions, some will not. If it has happened, gather the purchase email and order reference and contact us as soon as you can so we can take it up under whatever terms apply.

Yes. The step is not a file copy between two phones; it involves the provider's systems deactivating one profile and activating another. Do it where the Wi-Fi is steady rather than while travelling or in patchy coverage, because a drop partway can leave a state that support has to clear.

Where you have the choice, finish the handset change first and then buy and install the plan on the new phone. That order removes the transfer question entirely and gives you time to test the new device at home. If the change has to come afterwards, check the transfer conditions first and do not delete the original profile until the new phone is fully working.
