It is always quite tricky to convert a carrier locked device to the International version. It involves various steps that you should follow very carefully. After guiding you to unlock bootloader and Install TWRP recovery on OnePlus 7 Pro device, today we will help you to convert the T-Mobile based OnePlus 7 Pro to the International variant.

OnePlus launched the new flagship smartphone series last month featuring specifications like Qualcomm Snapdragon 855, fast charging, and QHD display. For the first time, OnePlus unveiled two new smartphones – OnePlus 7 and OnePlus 7 Pro to answer the increasing expectations from fans. It features a 6.67-inches Quad HD+ Fluid AMOLED display at 3120×1440 pixels resolution and an aspect ratio of 19.5:9. The device is available in three different variants: 6GB+128GB, 8GB+256GB, 12GB+256GB. The triple rear camera setup sports a 48MP+8MP+16MP sensors, and on the front there’s a 16MP pop-up selfie camera.

The conversion to a global variant facilitates users with global updates. Rather than waiting for the carrier to roll out update after several months, the user can easily enjoy the global updates directly from the OEM. It also allows users to install Magisk modules as these don’t work on the T-Mobile firmware.
