I've searched and searched and searched and still not found the information as it relates to sim blocking.
Basically I bought a phone off Gumtree, I was specifically told it was sim free - to which I was like, ok then. I did of course check the IMEI with CheckMend though as I always do.
However, unknown to me, my partner took out a contract for the phone I wanted and after skinting us buying the one off Gumtree, I listed the one I'd bought back on Gumtree. I had numerous people ask if it was sim free/paygo or contract. Never had this before when buying/selling phones. Since then, I have managed to sell the phone and also got my partner a newer phone and the bloke we got it off was like, it's sim free, that's important, won't get blocked.
As far as I was aware, if someone didnt pay their bill, they cut the service off/the sim became blocked/inactive. Are networks now blocking the phone by IMEI if a bill isn't paid? If so, how long have they been doing this? Surely a lot of people sell their phone on before the contract's up? I know I still have 6 months left of an 18 month contract and I sold that phone 6-7 months ago. I know not everyone does this but, a lot of people do.
Or is it a case of, if say after 3-4 months the bill isn't paid for on a new 24 month contract, do they block the phone under those circumstances, rather than say a few months left of the contract? Or just a blanket block whether you've had the phone/contract a month or 23 months?
I sell and buy phones a lot off Gumtree as I like to change and like I say, never experienced this before until the last month or so. Where all I get constantly is "is it sim free/payg or contract?"
