All CMobile plans are monthly plans. You are free to change to a higher
or lower plan at the end of each calender month. Simply give us a call
on 1300 545 000 or email email@example.com at any time, and we can
schedule the change to go through at the end of the current month.
NB. If you wish to change from a C Red plan to a C Blue plan or vice
versa, we will need to send you a new SIM, as they operate on different
networks. This will incur a replacement SIM charge of $4.90, which will
be added to your next bill.
