Re: If I buy an iPhone 5s and I'm on the go phone plan, does it need to be unlocked
You can most definitely purchase an AT&T-locked one, provided that you plan on keeping the phone with AT&T and have no intentions of switching over to another GSM carrier. If that is not the case, I would strongly recommend purchasing the unlocked model even if it is significantly more expensive.
