Make a phone network give more data in a contract

[Combat squirrel]

As title, my Mrs has an iphone 5S with a 2gb a month EE plan, I warned her this was no where near enough when she was getting it but ignored me, I knew full well with time data use would increase. Obviously now shes running out of data 18-20 days into the month and is annoyed at this.

Whats the chances of EE upping the data (£37 a month contract), to say 3-4gb ?

Anyone had good experiences with this ?
