Hi ​@Uddin1, 
 

Thanks for getting in touch.

If you’re currently on a SIM-only 1-month rolling contract, you’ll normally be able to upgrade or change your plan once you’ve been with us for at least 6 months.

If you’re on a 24-month handset contract, you’ll typically be able to upgrade or make changes within the final 24 days before your contract end date.
