Yes. Depending on your area, your options may be cable, WiFi, WiMAX, satellite, and cellular (EV-DO, 3G, Edge). In addition, you may be able to request a dry-loop from your DSL provider that just has DSL service (without phone service).
Actually, it is possible sometimes. Most smartphones need a 3G/4G service or data plan, but apart from that, many have Wi-Fi. The smartphones with the wifi feature can connect to a wireless router and acccess the internet without a service.
First you have a PS3 set up to a TV. Then you have an internet service. Then you purchase devices to allow the PS3 to connect to the internet like WiFi routers or Modems or an ethernet cable and a router or modem to connect it to. Then you go to the settings menu of the PS3 for internet connect and complete the set up for an internet connection. Without internet service and connection devices an online connection is not possible. The PS3 has WiFi which only means that it can connect to your WiFi internet service that you have set up. it does not mean you get an internet connection without having access to an internet service
Even though you have digital cable you will not be able to hook up your cable modem to it and get internet services without having purchased that service. The company has to set it up in a specific way and turn on that specific service in order for you to use it.
Yes. All you need is a low latency(<100ms) internet connection.
If you do not have a phone line you can still get internet service at your home. Cable providers such as Comcast and Quest can both provide high speed internet access without ever having to install a phone line. Also, there are some internet service providers which operate using a satellite dish and require no installation or wires or lines.
Yes. The internet has nothing to do with a Flash drive. You can use the internet without having a Flash drive, and you can have a Flash drive without having the internet.
Truly it would be selling Internet service as an ISP (internet Service Provider) or WISP (Wireless Internet Service Provider). If you mean an Internet Business such as having a website where you are selling a product and/or someone else's product that is also an Internet business where you may or may not be selling Internet service.
No, that is not possible.
I'm not quite sure what you mean by account. If you are talking like on the Xbox, where you have to buy live, then no. All you have to do is create a username and you can start playing! If you mean to you need to have internet service and an internet provider then yes you can not use the internet without someone having internet service.
Yes, it is possible without port forwarding. However, you may have a problem with a firewall, not just the router.
You should still be able to - in Txt messages provided you have that service enabled by your carrier. Most carriers today differentiate between internet service and the different types of text messaging features, so it is possible to NOT have the more expensive internet data plans and yet still send and receive pictures via txt messaging. While you're at it, try using ChaCha. TXT any question you have to 242242 and within minutes someone at chacha will look it up on the internet and answer you back. It's a great way to have the power of the internet without having to pay for internet service on you handset.
Not the entire Internet, no. It probably means you've paid a service provider for Internet ACCESS, though :)
