Why do you need to trust the carriers? They MUST unlock your phone if you're off contract and you request it. The FCC forces them to do so.
And yes, I didn't know the phone was missing the hardware at the time I made that post. So Verizon and Sprint are SOL for these phones. That's what people get for being their customers, who Verizon never cared about anyway.
Let me explain:
Some people do
completely trust the carriers to do right by them i.e not rip them off, this is more evident in the US than anywhere else. Why do you think they have been able to get away by not decreasing the monthly cost when you haven't upgraded or bought your own phone?
That is due to blind trust, oh they are spending money upgrading the infrastructure.. yes that is true to certain extent however some of that has been paid of years ago. But have the savings been passed down to the customer?
Also if that was completely true and they are in dire need of money to do the upgrades... yet how comes they are now starting to follow the contract plans that rest of the world was using for a loooooong time?
Pretty much it is the norm to decrease the contract to the base price when you don't upgrade, the base price being the SIM only contract price which is to be used when you've bought your own phone. For instance I only pay ?15 for mine and get Unlimited 4G LTE data, 600 minutes and unlimited data + use my own phone. How much is the comparable plan in the US?
Think about it.
Now put the above debate a side for a minute and step back - You will see
everything has an element of trust.
When you buy groceries you're trusting your super market chain or grocer for not to be selling out of date, uncared for produce or produce that hasn't been tempered down the supply chain.
You respect them as people and their operating policies (refund, complaints etc) which all ties into a brand identity, which is why you keep shopping there.
You have faith in them that what you're buying isn't being overcharged i.e two for one sales thus not being misleading. For instance a pack of 12 eggs is ?1 and a pack of 15 eggs is 1.25 - which is cheaper?
In regards to the carriers in general, you are trusting them to keep your calls, texts, data connection secure and safe. Not to mention that the device you bought will not be mysteriously killed off despite being sold only for a few months, that you will get timely updates and that their cellular coverage won't let you down.
You have respect for their operating policies (refunds, updates, complaints process etc).
You have faith in them of not tempering with the device or operating system in any way and that you can use the device you bought full price without any form of hindrance on their network i.e AT&T gimped the 1520 by halving the storage, removing Qi, certain providers do not give you certain features because they haven't been bought from their network of resellers or direct through them despite the o/s supporting them out of the box (ring any bells?).
So with any transaction be it verbal or monetary there is always an element of trust.
In principle, the core foundations for any sort of relationship be it business or personal, is Trust, Respect and Faith.
