Mobile phone( Is it locked or blocked)

[yesterday]

I have been on contract with my mobile phone for some years and Ive finally had enough of being ripped off. I want to go with asda PAYG as I now have a landline. I dont need to pay £15 a month on contract as £5 pay as you go would be sufficient. At present people can contact me, but I can't dial out. I cancelled my direct debit. I paid £25 twice to have my number changed because I had a stalker who managed to get my number. Why didnt the company just tell me to get a new sim card? This isnt the only issue Ive had with them. I dont really want to have to buy a new phone if possible. What are my options? Is my phone locked or blocked? and what is the difference. What can I do to be on mobile with the least expense to myself. Your advice would be much appreciated. Thanks.

They all have their own stores, perhaps they will be better equipt to answer you
