I have no landline so only use my mobile phone for calls. I call abroad sometimes and normally I would use my Tesco sim card for this, calling an '077' number which would connect me to a number in Mauritius. I usually had free minutes when I topped up so I was ending up paying around 5 p a minute. I cannot call to that number for cheap anymore due to their new pay-as-you-go tariff plan. So now I am paying 15p a minute.
Would anyone know where else I can find a better deal?
