The Vatican plans to use a device that disturbs signals around the Sistine monastery to block electronic monitoring or communication outside the papal election matehold, Italian news agency ANSA said.
Proposal is where 133 cardinals will vote to choose the successor to Pope Francis to lead 1.4 billion Catholics in the world.
The phone signal will be cut at 3:00 p.m. on May 7, local time, an hour and a half before the Rosaries arrived at the Sistine Monastery to begin the papal election mass, according to Italy's state broadcaster RAI.
The Vatican Court confirmed on May 5 that all 133 cardinals who will vote to elect the replacement of Pope Francis were present in Rome.
For centuries, catholic leaders have been elected through an extremely secret meeting called a conclave, which means the key in Latin, referring to the doctors meeting in a locked room until a new papal is elected.
The cardinals assigned to select the next papal must follow a complex process originating from the Middle Ages.
A Vatican spokesperson confirmed that doctors will have to return phones and all electronic devices starting from September 6 and will only receive the devices after the friendship ends.
All roses will be in the Sistine monastery and cut off from the outside world from May 7.
All doctors participating in the friendship will be completely isolated and sworn to keep it "absolutely and forever a secret".
The spokesperson said that turning off the signal will not affect St.Peter Square, where the public often gather.
Italian police said security has been enhanced throughout St. Petro Square, with checkpoints at the entrance and metal detectors along with drone control systems in public places.
Sistine monastery was completely blocked during the celebration to ensure absolute secretion. In 2013, in the papal concise, Francis's congress also installed signal blocking devices to block all calls, messages or Internet access.
Even electricians, water pipe workers and elevator operators who ensure Vatican operations throughout the conference will also commit to keeping the confidentiality.
All of them were sworn in and will be on duty full-time, overnight in the Vatican, and have no contact with their families, the Vatican City government said in a statement.
