The description for the luckeu S24U says it is T-Mobile compatible, but I get no network after inserting the SIM card and T-Mobile says it is not compatible. Can you help me?

While the luckeu S24U is marketed as an unlocked 5G device compatible with major carriers like T-Mobile, network issues can often be resolved by manually configuring the device or verifying specific band support. Since you are using Standup Wireless (which operates on the T-Mobile network), please try the following steps:Reset Network Settings: Go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. This often forces the phone to re-scan for compatible towers.Update APN Settings: Because Standup Wireless is a Mobile Virtual Network Operator (MVNO), you may need to manually enter their Access Point Name (APN) settings. Contact Standup Wireless support for the specific APN values required for their service on Android 14.Toggle Airplane Mode: Turn Airplane Mode on for 30 seconds and then off to refresh the cellular radio.Verify SIM Placement: Ensure the Nano-SIM is correctly seated in the tray as shown in the manual's SIM tray diagram.Note: There is conflicting information regarding this device's compatibility. While the product description claims support for T-Mobile, some user reports suggest the device may not support all necessary North American frequency bands. If the steps above do not work, you should contact luckeu customer support directly for a firmware update or carrier-specific patch, as the device includes a one-year manufacturer's warranty.
