New plan

Totally agree with MSF and JJP2 - if I may add, its also worth looking at your plan and considering changing to one with a higher allowance to avoid any interruption in the future - add-ons can be a lifesaver but might work out costing you more if you rely on them too much. With 30 day plans its easy enough to change up or down as you like (just bear in mind that changes only come into effect on the next billing cycle).

Richard_2161731 Smarty plans last for a month so, although you have used your data, the plan can still be used for calls/texts.  As JJP2 says, you can buy a data add-on until the expiry of the current plan. You could remove the auto-renew on the current plan and choose a more appropriate plan for the next month and then make it auto-renew if that works for you.

You can’t buy a new plan, BUT you can buy data add ons,,either online or within app, to see you through until your next plan starts.

Worth remembering that data add ons never expire on Smarty, so any add on you buy now will last until it’s fully used. I still have 1.28 GB of data to use from an add on that I bought in June.

Various add ons are available, in addition to the ones in the screenshot below.
