I want to start a business and I have an idea.?

However, as part of my business, I will have to go to people's homes with my laptop and Internet service. I only have dial-up Internet right now. Obviously I will have to upgrade. Some of my possible clients may not have Internet service. Is it possible for me to have Internet Service at all times on my computer no matter where I travel to? And if so, how do I get this? If I can't have Internet Service on my laptop when traveling to clients' homes who don't have Internet service, then this business won't work. Your help is greatly appreciated.

You could get a broadband wireless card from Sprint, AT&T, Verizon, or what ever wireless carrier is in your area.

In the UK we have mobile internet which is becoming a big thing, and it uses the 3G network. With Vodafone's mobile broadband, you should be able to use the internet absolutely anywhere you would be able yo use your mobile phone.

But it is not set in stone... not everywhere in the UK has coverage and speeds can change dramatically from area to area. That said, I think your best option is satellite internet. I have no idea how good it is and how much it costs, but theoretically you should have a better coverage and range... But you will never have the 100% guarantee which you need with your business idea.

there is internet service that is available through the phone companies that you just plug a thing into the laptop

check with the phone companies

you can get a wireless card for your laptop from your wireless service provider (I.E. Verizon, ALLtell, AT&T) slap that baby in and your good to go
