Hello, I am enquiring about repair of [device] in Macau. If a whole-device exchange is proposed, please describe repairing the original and replacing the whole device separately, including scope, cost and what is delivered. What are the replacement model, condition and recordable identifier? Will the original device be returned; if not, how will it be handled? What can and cannot be done to retain or transfer data? How is my agreement obtained before changing the plan, and how is the device identifier checked at handover? This is an enquiry only; exchange or handling of the original device and its data is not authorised.
