Sky Mobile Contract- additional phone

[brace123]

I have 2 sky mobile contracts, after 11 months I have over 300gb of spare days from these contract.

If I purchase another Sky Mobile contract, and no data plan, can I piggyback the some of the spare data from my 2 existing mobile phone contracts to the new phone contract each month?

Thanks in advance for any help

you need a dataplan/SIM to use the piggybank.

Sky sometimes offer a low usage SIM (100Mb) that would be suitable.  If not, you'd need to pick the lowest plan available.

However you may wish to review your existing plans as they may be excessive for your needs.
