Think I need to unlock phone?
I’m a relative novice with phones so please be gentle!
I have a Samsung Galaxy S8. It was originally on an O2 contract from 2018, and I switched to Giffgaff in 2019 with no issue. I’ve just switched to Sky mobile but it won’t work. The message is “SIM network PIN blocked. Enter SIM network PUK.”

I spoke to someone at sky who didn’t have a clue. All they could suggest was sending a new sim, but that’s clearly not the problem as the sim I am trying to use does work in an old iPhone.
I think the Samsung must be locked or have another problem. I didn’t expect any locking issues because I thought Giffgaff and Sky both used the O2 network. I’ve seen something on the internet that said there was a defect with some Samsung phones, and you need to ask Samsung for an MCK code, so I contacted Samsung and they said I needed to contact the old provider, I.e. Giffgaff, but that’s not easy when you’ve already left them.
Can anyone suggest anything?
If it needs unlocking, how can I get that done? All the high street shops are shut during lockdown.
I might be best to see if we can cancel the whole transaction and go back to Giffgaff.
Thanks for any help.

Look on the back of the SIM card surround (the credit card size plastic bit). There should be an 8 digit PUK on there.
If you binned that, then ask Sky Mobile for it again.No free lunch, and no free laptop0 -

Google says try 8 zeros. Failing that, you'll have to call Sky and ask for your PUK.No free lunch, and no free laptop0

It looks like we could get the Samsung unlocked for about £25 from a link on the Giffgaff website to a third party unlocking company.0 -

Try eBay, probably a lot less than going via giffgaff. a brief search throws up 270 offers for an S8, average price around a tenner.No free lunch, and no free laptop1
