General Mobile GM 24 Pro (G514 / G515)
- A phone released by General Mobile in August 2023 under the new "GM 24" series. It is known to be "COOSEA F40 Pro" from COOSEA GROUP's websites before the phone's launch along with GM Phoenix 5G being COOSEA X9, but both of the phones seem to have vanished from COOSEA's website after both the phones have launched. The phone features a stunning 6.7-inch AMOLED display with decent performance with it's Helio G99 processor. Some of the cons of the phone are the camera and microphones. They are very under acceptable quality.
Disclaimer! This phone is also known as:
- COOSEA F40 Pro (ODM model)
- DCODE Bold 3 Pro (Pakistan)
- NUU A25 (USA)
- nuvey PRO K10 (Uzbekistan)
