This is why whenever I am changing contracts/numbers I always turn the old number into a PAYG and keep the SIMNo one gets my old numbers!!
That doesn't always work!!.. My Mum had my old phone and SIM with the number converted to PAYG.. she didn't use it for about 18 months and Voda decided to re-allocate it to someone else with out prior noice!.. it was only when my Mum tried to use it (for an emergency!!) that she found this out!!![]()
