New Connections
Within around six days of connection, customers will receive their first bill from EE. This will be for one full month’s line rental to cover the monthly recurring charges in advance. The new package is effective immediately and in the majority of cases, the customer’s billing date will be the day after connection to prevent any Pro-rata implications to their inclusive allowances.

Additional Lines
If a customers adds another line onto their account part way through their billing period they will see part charges on their next bill – A part charge for line rental for the additional line from the date of connection, up to their existing bill date plus one month in advance. It’s the same for their inclusive allowances too, they will only receive a partial allowance to use from date of connection until their existing billing date.

EE to EE Upgrades
If a customer has changed price plan it is effective immediately, therefore this will create part charges on their next bill, which will appear as: - A Pro-rata refund of the old plan (as it was paid one month in advance)
- A Pro-rata charge for the new plan (to cover the date the charge became effective, until the existing bill date)
- A charge for the new price plan, equivalent to one month in advance.
- It's the same for allowances too. Customers will get a partial allowance refund for their old price plan and a partial allowance for their new plan to cover them until their bill date.

Moving to EE
When a customer migrates to EE their Orange/ T-Mobile account will be closed. Their final Orange/T-Mobile bill will act as their first EE bill and will detail a Pro-rata refund of their old plan (because it was paid one month in advance) and a charge for their new plan equivalent to one month in advance.
A new Account Number, bill date and Direct Debit date will be set up for their EE account. The new billing date will, in most cases, be the day after connection to prevent any Pro-rata implications to their new inclusive allowances.
