Lebara 50% off deals

Hi all

can you get the 50% off deals by topping up as an existing customer or are these contracts or for new customers only?

I’d like to know too please, I just purchased a sim for £9 for 1 month, but I’ve ported my number, do I buy another sim to get 50% off? And then import my number again
the savings are significant, £2.78 until May 2026
