● The cellular data internet is disabled after you pay the fee. Press and hold the power button until Reboot option appears, choose Reboot to restart your phone.

● Factory reset your phone if above methods don't work, or ask the seller for help.
The UMI ROME X phone supports dual SIM dual standby, if one SIM card doesn't work:
● Check if you have activated the SIM card: Settings - SIM cards - SIM card 1 / SIM card 2 - Activate, tap the option.
● Insert the SIM card 1 to the SIM card 2 slot. If it works fine, maybe the SIM card 2 is overdue or it has something wrong. If the card doesn't work as well, clear the SIM card slot and your card with a soft cloth.
The SIM card 2 still doesn't work after trying above solutions, maybe the SIM card slot is broken, please contact the aftersale service to fix the phone.
