Hi ​@Harvey8453 

starting from two months before the end of your contract (or 60 days).
To check your specific upgrade date, log in to the iD Mobile app or My Account online and go to the "Plan" section, where you'll see if you are eligible to upgrade. 

• For Pay Monthly Phone plans: You are eligible to upgrade up to 60 days before your contract ends.
• For SIM Only deals: You can upgrade to a new Pay Monthly Phone plan after you've been on the SIM-only plan for at least 6 months.
• To check your upgrade eligibility: Log in to the iD Mobile app or My Account online, go to the "Plan" tab, and look for an "It's time to upgrade!" button.
• If you are not yet eligible: You can switch to a different plan if one suits your needs better, as long as you meet the eligibility criteria for plan changes. 
   

If you want to confirm the details then you can either contact the Live Chat:-

Type ‘talk to a person’ when you open the dialogue box to bypass the chatbot.
Please be patient as the agents handle a few conversations at any one time so there will be a delay in connecting with an available agent and also any replies to your query.

Or  email socialqueries@idmobile.co.uk.

Good luck x x
