If I buy a new sim for a new phone, and wish to only top up as and when I need credit (i.e. 10€ in January, no credit in February, €15 in March, €25 in April) would this affect my plan? I know free unlimited data is not offered unless you pay 20€ , but is buying credit in this way a breach of your contract with three?
Hey there, the prepay plan will only last for 30 days. We do have plans for €10/€15 that if you topped up when your plan expired these plans would activate, But once you top up with €20 again you'll get that plan back. If you need more info let me know
