Unlocking vs Jailbreaking an Iphone 6S

>>185210
Jailbreaking and unlocking are completely different things.

Jailbreaking is done on the "application processor", i.e. the CPU, and lets you run programs that aren't signed by Apple.

Unlocking is done in the "baseband processor", i.e. the 4G modem, and lets you use an unauthorised SIM.

There's no unlock for any modern phone, because there's no market for it: people that aren't willing to pay their carrier £15 for a legitimate factory unlock are hardly going to pay for a pirate unlock.

O2 claim they'll unlock your phone for free anyway:
>If you're on a Pay Monthly tariff, you can ask us to unlock your phone at any time, for free. This policy might vary depending on which phone you’ve got.
>This doesn't affect your contract though – you'll still need to see out the rest of it, depending on your phone and tariff.
>The only way to unlock your phone is by using My O2 online or via the main menu of the My O2 app. Once it's unlocked, we'll text you to let you know

Re your data bill, phone O2 up and give them the third degree. Threaten to take them to the Ombudsman for Communications*. Point out that in the EU, they're legally required to warn you when you've used €50 of roaming data, and thus just letting you spend willy-nilly in a nearly-EU country was not fair practice. Negotiate. You'll probably be able to come to some kind of arrangement.

The thing you need to emphasise is that the charges were not made clear to you at the time you used your phone.

For example, whenever I land, I get a text that says "Welcome to *wherever*. You're on *whatever operator* now, and data costs *whatever*".

If you never got a text like that, you can say that they didn't make it clear to you what roaming was going to cost.

("whatever" is usually "£0.00", because I'm on Three).

Okay so does the above imply that jailbreaking does not unlock an iphone and thus it is impossible for me to unlock my phone without o2?

Did you maybe skim over

Okay but I just wanted to confirm that although there's no market for it, there's no pirate unlock available.

What jailbreak (tool) are you using?

>>185348
Not using any tool until now since I don't know whether or not it could unlock my phone

>Based Three.

My last phone came already unlocked.
