What can I do if Bell Canada refuses to unlock my iPhone without a subscription?

You could consider signing up for a plan just to unlock your phone and then cancel it within the 14-day cancellation period. However, keep in mind that you might still need to pay upfront for the full month if you go that route.

I'm not sure about the laws in Canada regarding unlocking, but I've heard that unlocking rules have changed in other places. If it's just about unlocking a device, a third-party service might also help. Just be cautious, as they may affect your warranty.

If you're still financing the phone, it's technically Bell's until your payment plan ends, which is usually two years. If it's an old phone that's locked, you'll have to contact the original carrier to request an unlock code, but it seems like that's not helping you right now since Bell won’t unlock your iPhone without a subscription.

If your phone was locked by Bell, then unfortunately they should be the ones to unlock it. Legal action could complicate things, so it might be worth trying to calmly discuss your situation with them or see if there's an alternative method they can offer.
