Upgrade package

[#1]

My current useage is about 7- 8 Gb per month hence I am on the Essentials package
If I take out a new 24 month contract on this package, then later on exceed 10Gb can I upgrade to Unlimited within the same contract period
This would be to avoid the £5 per Gb penalty charge
or will I get a penalty charge each month until the end of the contract

Hello Bures,
You can change product any time, without it affecting your contract as long as it's within the same product family, i.e. Essentials -> Unlimited, Unlimited -> Essentials, The contract may be effected if you switch from ADSL to Fibre , for example.
For the cost difference, you might as well go to the Unlimited package, then you'll never run the risk of having to pay extras.
Cheers,
Matt
