SIM card locked. (What do I do?)

hstraf — Wed, 05 Jan 2022 16:53:05 GMT

Hello,

I just purchased a used iPhone froma friend, and I am trying to switch to use it. However, when I put my Public Mobile SIM chip into the used iphone, it shows this message:

-------------------
SIM is locked - 1 attempt remaining

-------------------

I tried putting my iPhone unlock passcode into it, but that does not work. (I just restored the Iphone from iTunes backup.)

I logged into my Public Mobile online account, but I don't see anywhere to set the SIM passcode.

What should I do?

UPDATE: I just put the SIM chip back into the old phone, and it still says "SIM Locked".

So now I can't use either phone any more.

How can I unlock the SIM?

The default SIM card PIN on all Public Mobile sim cards is 1234. If this doesn't work and you enter one more incorrect code, I beleive that you're going to need to ask moderators for your SIM card's PUK.
