Hi,
I have an orange pay as you go, and I am sure the mobile to landline calls are 25p per minute. Orange are useless at customer service, I applied for a monthly sim card only, they sent me one, not the tariff I wanted, there is one with unlimited landline calls, several hundred texts etc. for £15 per month,which I thought would be ideal as I do not text anyone. then they told me I had failed their credit check for some unknown reason, then on my next bank statement they were taking the money, having set up the direct debit.
