Can I use my HTC Evo 4G LTE (Sprint) as a dial-up modem through my laptop? Many will ask why, and most will say you can tether the laptop to the phone to get internet access, I already do this. Let me explain... I work in the commercial HVAC automation industry. Our building controllers have dial-up modems as a backup/remote connection. The time comes from time to time that I need to connect to the site remotely to test the modem or check on the site's status after repairs. Our old laptops had internal Verizon aircards that could be used for dial-up service. We have have since upgraded laptops and no longer have the internal modems. We have been provided 3G or 4G external aircards from the big carriers. I have tried to set up my Verizon 3G aircard with no success. I have worked with the other techs to do the same with their AT&T and Sprint devices with the same result. I have also contacted the service providers and modem manufacturers with zero success. I think if the device can handle it, it needs to show up as a modem in the device manager. I sometime have to use Hyperterminal for our oldest sites and our building managment software for the rest of them. I'm not necessarily stuck on the EVO, this is a trial phone for us, we're supposed to run them though their paces and see how we like them. My normal work phone is a HTC Inspire 4G LTE (AT&T).
