How to Fix a DNS Error on a Cellphone

1. Type in the name of a different website other than the one you first attempted to access and click or tap "Enter." If another website loads correctly, you know the error has to do with the first website you tried to access.
2. Clear the cache -- a virtual directory where the phone's Web browser stores copies of Web pages -- in the browser's "Settings" menu. If a fleeting error occurs, the browser may store the error page in its cache as the sole record for the Web page, indicating an error has occurred when, in fact, no error is present. Clearing the cache eliminates this possibility.
3. Reset the wireless router or modem if you use Wi-Fi to connect the cellphone to the Internet. If the DNS for the Internet service provider has caused the DNS error in the Web browser, resetting the modem resolves this problem.
