Do iPhones coming direct from o2 come unlocked?
I placed an order for an upgrade on the o2 phone network. I have an iPhone 6 and I was going to order an iPhone 8 from their website. It was my understanding that phones sold come unlocked and are only locked to the network of the first SIM card inserted into the phone. O2 are telling me however that phones sold directly from o2 are locked to the o2 network when dispatched. My previous iPhone was locked to o2 however I used the Three sim in it straight away therefore locking it to Three instead. The difference is that phone was sold from a third party reseller. So question is does phones sold direct from o2 come locked to o2? Thanks
