Yes, it is possible to transfer or relocate a PLDT landline number and handset from one building to another. This process is known as a change of address request. When you move to a new location, you can request PLDT to transfer your existing landline number and handset to your new address.
To facilitate the transfer, PLDT will need to reconfigure their network to connect your landline number to the new building's infrastructure. This may involve physical changes in the wiring or activation of services at the new location.
Regarding the existing PLDT router/modem with the landline number and handset, you can bring this equipment to the new building. However, PLDT may need to reconfigure the settings to ensure that the equipment works properly in the new location.
To initiate the transfer process, you will need to contact PLDT customer service and inform them of your intention to relocate your landline number and handset to a new address. They will guide you through the necessary steps and provide you with the required information to complete the transfer successfully.
It's important to note that there may be additional fees or charges associated with transferring your PLDT landline number and handset to a new building. Make sure to inquire about any potential costs during your discussion with PLDT customer service.
