If I buy a new phone, are my contacts on the SIM or in the phone? Current phone is Motorola Moto G version 3, thinking of buying version 6, would be nice if I can just put SIM in and all contacts are there.
Do you have a google account??
If so, is your phone connected to it and have you got "sync" turned on??
If the answer is yes to all of the above, then when you get a new phone, simply log into your google account and all your contacts, etc will be automatically transferred onto your new phone.
