I have a fairly basic question to ask:
If I happen to buy a cheap pay-as-you-go phone from Carphone Warehouse, can I just simply pop my current SIM card into the phone and carry on making calls and sending messages straight off the bat?
Or is there an activation process involved?
Thank you to whoever helps!
