Carier network for iphone 4?
If it is a used phone it will likely have the carriers brand name on it. If it is unlocked with a SIM Card T-mobile, AT&T, and T-mobile are options.
You might be able to see the Carrier on a used phone when you turn it on because it will likely log into it even if only for 911 call of unactivated phones
- Wi-Fi on iPhone keeps saying unable to join network (my network name)? How can I fix this! It's been like this for a week but it works on my laptop fine. I tried unplugging it for a few seconds, I tried resetting network settings, I tried turning my phone off then on again, and I know I'm typing it right. I even typed it in upper case AND lower case. Does anyone know how I can fix this?
- What's the difference between off-network and on-network? I'm try to work out which is best for what I want out of the service.
