To not buy more phone credit

[RoseMartha]

Dd age 13 wants more credit.

She uses wifi at home.

In two days used up all her data. Mainly making tictoks and using sm to message friends photos and videos when out.

Now she wants more data.
I have told her she needs to learn how to budget her data over the month. I am on fairly tight budget.

She still has unlimited texts and 500 mins of calls left.

I know if I pay for more it will be used up just as quickly. AIBU to say no?

If you look on Uswitch, you can compare SIM only deals.

Smarty give 30BG for £10. You could also look for lower cost contracts that way. When she's earned it, obv!
