Judgementday

Respected kabam, I purchased a new phone and gave my old phone to family member.. Now I want to open my kabam account on new phone.. Is there will be any problem, if any, how can I switch to new device.

If you had made a Kabam ID for logging into the game with, you can just log into that same Kabam ID on your new phone and have access to the same game account.

If you had used GameCenter/etc. then using the same on new phone will also work.

But if never made a Kabam ID (first, go back to that family person and go make one on it, then come back to your new phone).
Or if used GameCenter/etc and switching base OS (Apple to Android or visa versa), then go back above and create Kabam ID, method to do this and maintain old account is very tricky, before going back to new phone.
