After being launched in Seoul on May 18, the LG G4 has begun its global rollout in Hong Kong, Turkey, Russia and Singapore, which will be the first ones to receive the flagship smartphone, though the exact release dates have not yet been disclosed. Eventually, the LG G4 will be made available across most regions of Europe, North America, the Commonwealth of Independent States (CIS), Southeast Asia, Middle East, Africa, South and Central America. The South Korean tech giant has reportedly partnered with 180 service providers and retailers across these regions to market the LG G4.

LG and T-Mobile are on a nationwide tour of the U.S. to promote the LG G4, and have stated that the all-new flagship smartphone will hit the U.S. carrier's stores on June 2. Meanwhile, Verizon Wireless will be selling the LG G4 from June 4, while Sprint and U.S. Cellular will also be offering the flagship smartphone in the coming months. However, none of the carriers have revealed the details of their contract plans for the LG G4 and the company has stated that prices will vary worldwide. Early reports indicate that the LG G4 will retail for around $600 without a contract, or about $200 as part of a U.S. carrier deal. U.S. buyers of the leather-back LG G4 will also receive a spare battery unit, an extra wall charger and a 32GB microSD card.

Ahead of the nationwide release of the flagship smartphone for the U.S. market, LG has also introduced the G4 Stylus and G4C, which follow the design of the G4. Unlike the G4, neither the G4 Stylus nor the G4c will be available in leather-back options, and will be showing up in "key strategic markets in weeks to come," according to LG.
